Interesting DIY mechanical devices. Homemade machines and devices for the home workshop

A good owner always has his own workshop, which he fills with equipment and devices to suit his needs. Some things can be bought, but others can be built with your own hands. And we must not forget about the garage, because all the necessary equipment should also be there.

It is impossible to provide for everything that might ever be needed. Therefore, we will consider the most basic machines and mechanisms that can be useful when working with wood or metal.

How to make a universal machine with your own hands

There is a huge amount of different types of equipment, many of which in one form or another can be made independently. Craftsmen have even learned to combine several functions in one device.

For example, you can make a universal mechanism from a regular drill that will work like:

a circular saw;
grinding;
cutting;
sharpener;
turning.

To make it, you need to attach a drill to the frame. A board with a thickness of 20–25 mm is chosen as the base. The drill is fixed to that part of the body that is intended for attaching another handle.

The place of fixation on the tabletop is selected based on the size circular disk, grinding wheel, cutter, sharpening stone.

To secure the drill, use a firmly fixed threaded rod and nut. Rigidity of fixation is achieved using epoxy glue and, as an addition, a pin 2 mm in diameter. We build a moving sole and that’s it, the base is ready.

To get homemade circular saw, install a saw blade with a diameter of 15 cm on the drill chuck and make a slot for it in the bed. The saw blade must be protected by a metal casing.

If you plan to use a flat cutter instead of a disk, you need to additionally make a rectangular slot or widen the hole for the saw.

From this “circular” saw you can build a cutting mechanism. To do this, on a rigidly fixed surface we install a rotating bracket, a miter box that sets the cutting angle, guides and devices that secure the workpiece.

We combine this with a circular saw on the bed. Grinding and turning machines are assembled using the same principle.

Making a circular saw with a frame

If you want to have a separate circular saw, then you can easily build it from a manual circular saw bought in a store. Such homemade mechanism not designed for too heavy loads, but suitable for occasional use on the farm.

We take a frame of suitable size and fix it on it manual circular saw, make the maximum cut and leave it in that position. We turn the base over with the circular side down and place it firmly on the frame with legs.

We make a guide and everything is ready to go. Please pay Special attention to the height of the machine, you should be comfortable working with it, and its height should be commensurate with your height.

You may also need a pipe bender in the workshop. This is a device that allows you to bend pipes from almost any metal, as well as strips. Bent pipes are required when a person decides to make, for example, a greenhouse or a greenhouse or something like that.

There are different types of pipe benders, let’s say, made independently. There are very simple ones, and there are others that are similar in design to factory ones; they are more difficult to manufacture.

The simplest option homemade pipe bender we get it by sawing the board on one side in a semicircle. Then this workpiece is attached to a stable surface and a limiter is mounted next to it - a wooden part that has space up to the semicircular workpiece, into which one end of the pipe is inserted.

Features of homemade devices and equipment

You can talk for a long time about what equipment you can make for your workshop with your own hands. But everyone has their own needs and capabilities. In addition to homemade devices, there should be places to store tools, as well as a workbench.

You should take the construction of a workbench seriously. You need to think about what will be attached to it, where it will stand, and what materials to build it from. The tabletop can be made of metal or wood.

You can immediately attach a circular saw, for example, or a jigsaw, various kinds of vices, clamps, and so on. It all depends on your idea and need for this or that equipment. But the workbench must be the right comfortable height, stable and well made.

Also in the workroom, various types of cabinets and pencil cases for placing and storing existing tools, which you can assemble with your own hands, are very useful. Can be equipped separate places for storing large tools and separately for small ones, for example, a separate open cabinet for drills.

The convenience of work, how quickly you can find the necessary tool or part and, ultimately, your comfortable well-being depends on how you organize your workspace.

What can be done for the garage

Often, a garage becomes not only a place to store a car, but also a place for many necessary tools, and sometimes a workshop at the same time. Therefore, here you need to have:

Tools for car repair.
Spacious racks for their placement.
Garage workbench.
Hooks.
Shelves or brackets for tires.
Lamps and heaters.

These devices are easy to assemble with my own hands. The organization of the garage space should be well thought out. Everything should be placed conveniently and not take up much space. Think about whether you need a workbench and where to put it, what size it will be and in what places to place racks and shelves.

A workbench will be needed if you are repairing your car yourself. Typically, all tools are located on shelves and racks next to the workbench. Spare tires are stored either on a special rack or hung on brackets on the walls.

Place all fuels and lubricants on a separate rack. Most often, some difficulties arise with storing small parts: screws, nuts and the like. You can take small ones for this glass jars with screw caps.

Screw the lid to the shelf below, sort all the small items into separate jars. This way you can save space and put things in order, and the search for the right screw, drill or nut will now be reduced to a minimum.

For these purposes, you can choose another option. You will need magnetic tape, small clear plastic containers with durable lids, and metal flat washers. Fix the magnetic tape vertically in the place you need.

Attach metal washers to the bottom of the containers. Sort all the small fasteners into ready-made containers and hang them on a magnetic strip.

For repairs you will also need inspection hole. And if it is not possible to equip it, then you can build two overpasses to lift the front or rear or side of the car. This will allow you to fully carry out all repair operations. Overpasses are made of timber and durable boards or metal, if possible.

Well, in the end, good lighting is very important for the garage. It can be general and as an addition to portable and local lamps. And make sure that there is more than one outlet in the garage. If you are repairing the car yourself, then you need to think about ventilation of the room.

This article discusses homemade machines and devices for the home workshop. Here we detail the features of the most popular and necessary DIY tools, as well as tools for the workshop or garage, step-by-step technologies their manufacture and other useful recommendations on this topic.

Many home workshop owners create the equipment they need with their own hands.

Homemade machines and devices for the home workshop: general information

Each owner of a garage or workshop, depending on his needs, selects the equipment himself. Many of them know how to make homemade machines and devices for garages, so they get by on our own when arranging the premises, customizing the technical features of the structures to suit you.

So, when creating metal drawings and the dimensions of the product on them can be adjusted to the parameters of the room and other conditions. Even for a small home workshop, you will need to allocate enough space to accommodate at least the design of a universal folding workbench and a minimum set of tools. The required area for this is at least 3-5 m².

Helpful advice! It is better to arrange the workshop in a separate room, so that noise from the work of a homemade grinding machine woodworking and other tools did not interfere with the residents. A garage can be allocated for the placement of machines, the area of which is sufficient for comfortable work and installation of equipment.

Manufacturing of tools storage devices: shelves, racks

In fact, it is very difficult to achieve optimal operating conditions. It is desirable that the size of the room be at least 6.5 m. To equip a workshop, you can make an extension to the house or garage. This solution will be the most profitable in any case.

Before designing a drawing of a folding workbench with your own hands, which has the largest design (therefore its dimensions are taken into account first), it is worth deciding on some points:

indicate what types of work will be performed in the workshop;
determine a list of necessary tools and equipment.

By mounting the tool on the wall you can save a lot of money usable space In workshop. Shelves or racks are perfect for this. You can successfully arrange these structures, achieving the most rational distribution of area.

To save space, you can get special device for a circular saw with your own hands, made on the basis of a conventional drill. Such universal machine can perform several functions at once, combining the following capabilities:

circular saw;
grinding machine;
sharpened;
cutting machine.

The desktop can be combined with carpentry workbench and equip it with drawers to store small tools.

DIY tool shelves: popular designs

Metal structures are more durable and reliable, while wooden ones are affordable.
There are several options for rational storage of tools:

wall shelves;
DIY tool racks;
suspended ceiling shelves;
Shelves-boards for hanging small tools.

Helpful advice! The shield shelf is very convenient for metalworking and carpentry work. You can install holders or hooks for tools, small shelves or containers for fasteners on it. It is most advisable to hang such a structure over a folding carpentry workbench. You can even provide additional lighting. It is better to use a small lamp for this.

Technology for making a shelf for tools with your own hands (shield):

A shield is cut out of a plywood sheet, and the places where the shelves will be installed are marked on it.
Using a jigsaw, shelves with side walls are cut out. The length of these sides must match the length of the shield.
Shelves for tools are assembled and fixed to the surface of the shield using long self-tapping screws.
Hooks are being installed. Holes are made in the shield where dowels are installed. You need to screw special hooks equipped with threads into them. First, you should distribute the entire tool and mark the points where it will hang.
Brackets or lugs are installed on the rear wall of the structure.

All that remains is to fix the shield shelf on the wall. To prevent the lugs from sliding off the anchors, it is recommended to fix them with special washers.

Making a carpentry workbench with your own hands: drawings, videos, technology

The drawing of a carpentry workbench should include the following details:

Working surface - for its manufacture it is recommended to take a board 6 cm thick or more. Suitable wood species such as oak, hornbeam or beech. It is allowed to use several narrow boards pre-treated with drying oil.
A do-it-yourself homemade vice design is attached to the top cover, which should also be included in the drawing. If you intend to install a large-sized product, it is better to use wood for its manufacture. It is allowed to make and subsequently install small metalworking vices made of steel yourself.
Workbench supports can be made from linden or pine. A longitudinal connection in the form of strips must be installed between them. This will increase the stability of the table.
Shelves for storing tools - mounted under the workbench. Designs can be fixed or retractable.

Helpful advice! The linear parameter of the workbench can exceed 1 m. The increased size of the structure can be used to install two carpenter's vices with your own hands.

There are several modifications of workbenches:

mobile;
stationary;
folding (universal).

Having familiarized yourself with the structure of a carpentry workbench, you can begin to manufacture it.

Technology and drawings of a do-it-yourself carpentry workbench: how to make a simple design

Step-by-step technology for manufacturing the structure:

To make a lid for a wooden carpentry workbench, you will need to take thick boards. The size must be selected so that, as a result of their connection, a shield with parameters of 0.7x2 m is obtained (the length can be less than 2 m). Long nails should be used as fasteners, which must be driven in from the front side and bent from the back.
You can finish the lid by securing a beam with a section of 50x50 mm along its lower perimeter.
Depending on the size of the carpentry workbench (its cover), vertical supports are located. To make them, a timber (12x12x130 cm) is taken. At this stage it is necessary to take into account the height work surface, because it should be comfortable. The upper limit of the support should be at the level of your lowered arms. Subsequently, due to the installation of the cover, about 8-10 cm will be added to this indicator. Markings for installing the beams should be applied to the ground and these elements should be dug to a depth of 0.2-0.35 m.
Next, we install the frame part and the cover of the wooden workbench with our own hands. The installed support bars must be connected in pairs. For this, wide boards are used, fixed at a height of 0.2-0.4 m with long screws. The cover is secured to the ends of the supports using the same fasteners.

Note! Do not use nails to install the cover. During the process of driving them in, the frame part of the product may move.

Technology for making a universal wooden workbench with your own hands

Despite the fact that the technology for creating this design is in many ways similar to the previous version, for the manufacture of a composite carpentry workbench, drawings with dimensions will be required. But in in this case Bolts are used instead of screws.

In addition, you can install drawers for storing tools in a folding universal workbench with your own hands.

Technology for making a folding workbench with your own hands:

Vertical supports are installed in a similar way and are connected to each other using horizontally located jumpers. Before installing the jumpers, grooves should be made on them for nuts and washers. To do this, it is better to use a hammer and chisel.
When the jumpers are set at the required level, the through holes in a horizontal bar and a vertically mounted support. The long bolt will be inserted here. On the side where there is a groove for fastening, put on a nut and washer, after which the element is tightened well.
You will need 2 horizontal jumpers for the frame part of a homemade carpentry workbench. on each of 4 sides. You will also need a couple of jumpers for installation under the work surface (in the center). The elements under the table top are designed for drawers. The distance between these jumpers must correspond to the size of the boxes.
Bolts are also used to fix the working surface. Mounting recesses are prepared at the ends of the supports, and holes for fastening are prepared on the tabletop. The bolts are installed so that their heads are recessed (1-2 mm).

Note! Drawings for a folding workbench are not as complicated as they might seem. The advantage of the design is that any damaged part can be easily replaced with a new one.

DIY carpenter's vice design for a workbench

Usually workbenches are equipped with a vice. Many garage workshop owners know how to make such a device with their own hands. For homemade design you will need special pins. Such fasteners are sold in hardware stores.

To work, you will need a special screw pin. This threaded part is the main operating component of the structure. The minimum pin diameter is 2 cm, the cutting length is 15 cm. The longer this part is, the wider the vice can be spread. If you take into account exactly these dimensional parameters in the drawings of a vice with your own hands, you can get a design that is set apart by almost 8 cm.

The jaws of the tool are made from a pair of boards. One part of the part will be fixed. To make it you need to take pine. The second part measuring 2x1.8x50 cm will move. In each of these boards you need to make a hole for a screw. Using a drill with a diameter of 1 cm, holes for the studs are formed in all boards at the same time. To prevent the holes from moving relative to each other, you can connect them using nails.

After all the holes are made, the screw and all the studs are inserted into them along with the washer and nut.

Helpful advice! To be able to process workpieces of different sizes, you need to make the studs repositionable. You will need to make a pair in each of the boards additional holes located close to the screw terminal.

Additionally, you can use the video material posted below to create a vice with your own hands.

Making a metal workbench with your own hands: how to make a metal structure

For plumbing work, it is better to make a metal workbench with your own hands, because a wooden one will not be suitable for this. The fact is that wood is not that durable. In addition, when working with metal workpieces, a tabletop made of this material will be constantly damaged and will quickly become unusable.

On general drawing mechanic's workbench With your own hands, you can identify five main components of the design:

For longitudinal rigidity of the product, horizontal beams (3 pieces) measuring 6x4 cm are used. Length – slightly exceeds 2 m.
Rack-mounted small-sized beams (9 pcs.) made of profiled pipes measuring 6x4 cm. They are used to assemble the frame part of the cabinets. In the corner area there are welded spacers made of steel strips. Due to all these elements, the frame is rigid and very durable.
Rack beams (4 pcs.) 9-10 cm long (section 6x4 cm). To do this, it is better to use metal profile pipes with thick walls (more than 2 mm).
Corner No. 50 (4 pcs.), which will be used as vertical posts. The height of these elements is 1.7-2 m. Working tools will be attached here.

Dimensions of the bench:

Helpful advice! In order to make high-quality seams, it is recommended to use carbon dioxide semi-automatic. Experienced craftsmen can use a pulse-type welding machine. If you lack skills in handling this tool, it is better to entrust the work to professionals.

Do-it-yourself workbench manufacturing technology: how to assemble

Making a universal workbench with your own hands begins with assembling the frame. To do this, you need to take a couple of short and a couple of long beams. During the welding process, these elements may become twisted.

To prevent this, you must:

Lay out the parts on a perfectly flat plane.
In the places where the connecting points are located (there are 4 of them), the beams are tacked using the spot welding method.
After this, all welding seams are fully completed. First on one side of the frame, then on its reverse side.

Then the rear vertical racks and the rear beam (long, one of three) are attached. You definitely need to check how evenly they are placed in relation to each other. If there are any deviations, the beams can be carefully bent using a hammer. At the end, the remaining vertical rack elements are assembled, as well as elements that provide rigidity.

When the frame is ready, corners can be welded to it to strengthen the structure. The tabletop is formed from wooden planks. They must first be soaked in a fire-resistant liquid. Then a sheet of metal is laid on top.

A plywood tool shield can be mounted on the vertical rack elements. The same material is used to sew up the cabinets. Can be used for boxes metal boxes or make wooden structures.

You can use the video below to understand in more detail the technology of making a workbench with your own hands:

Features of creating a wood lathe for a home workshop

In the technology of making a wood lathe with your own hands, the bed occupies a special place. The operation of other parts, as well as the stability of the entire structure, directly depends on this part. It can be metal or wood.

Helpful advice! To make a wood lathe with your own hands according to standard drawings, it is better to use an electric motor that can reach a speed of 1500 rpm. The optimal power indicator is 200-250 W. If you plan to process large workpieces, you can increase the power ratings.

To create a turning - copying machine for woodworking with your own hands, you can use an old one that is no longer needed. This tool is placed on a plywood platform 1.2 cm thick and 20x50 cm in size. You must first make holes in it for fastening elements. Stops made of bars will also be mounted here. They are necessary to ensure that the cutter is in a fixed state. The router itself is secured with two nails between the clamps.

In fact, it is absolutely not difficult to make a copy design of a homemade wood lathe with your own hands - there are enough video materials on the Internet.

An example of a homemade wood lathe with your own hands

For the basis it is better to take steel profile with thick walls. To make the structure reliable, it is recommended to use two supports. A frame will be installed on top of them. To fasten parts, a groove type of connection is used. First you need to make support platforms intended for the headstocks (rear and front).

List of parts for a wood lathe (it’s easy to understand how to assemble the structure yourself based on this list):

Power component - you can use an electric motor from an old pump or washing machine.
Headstock (rear) - a head from a drill with a high power reserve is suitable.
Headstock (front) - to organize this part, it is better to buy a factory spindle equipped with 3-4 pins. Thanks to this, it becomes possible to shift the workpiece relative to the rotational axis.
The supporting element - the table for incisors - can be of absolutely any configuration, the main thing is that it provides comfort during work.
Pulley - is a connecting element between the headstock and the shafts in the electric motor.

Note! To work with this design, you will need to purchase a set of factory cutters. If you have the right tool, you can make them yourself, but you will need tool steel.

As supporting information, you can use a video detailing this process to assemble a wood lathe with your own hands.

The second example of a DIY woodworking lathe

An alternative solution would be to make the design of a simple mini-wood lathe with your own hands based on an electric drill. This example of technology can be used as a test before building a more serious tool.

This type of machine is suitable for processing wooden blanks small size. The material for the frame can be wooden beams. The return headstock can be replaced by a combination of a shaft mounted on a support bearing. To fix the workpiece you will need to get the appropriate one.

This design has its disadvantages, they are associated with:

high probability that errors will occur in milling;
low level of reliability;
inability to process large-sized wooden workpieces.

But you shouldn’t give up this option, because it forms the basis for technologies for creating more advanced and complex turning tools. To correctly calculate the design, determine for yourself the necessary operational properties and technical characteristics.

The principle of making cutters for a wood lathe

The technology in this case is complicated only the right choice workpieces, which not only must have a level of cutting edge hardness that meets the requirements, but also must be correctly installed in the clamp - the holder.

Note! In the absence of tool steel, you can make do with improvised means. After the preliminary preparation stage is completed, the material is further hardened.

Reinforcing steel bars - it is better to use options that have factory original dimensions and square shape sections.
Files or rasps - worn-out workpieces are suitable, but it is not allowed to use material with deep chips or cracks.
Automotive springs - before using these blanks they will need to be given a square shape, which not everyone can do. For this purpose it will be useful welding machine. Autogen will also do.

Turning: A - with a semicircular blade for rough turning; B - with a straight blade for finishing turning; B - shaped; G - machine passage

The machine can provide the ability to change cutters. For this purpose, a special modification of the housing is made with the necessary mounting parts. These elements must be strong enough to withstand the loads during operation and at the same time maintain the original location of the edge part.

When the cutter is made, it is sharpened, and cutting edge hardened. After the cutting part is heated, the cutter must be dipped into machine oil. Using slow hardening technology, the surface of the product can be made as hard as possible. In this case, the heated workpiece should cool naturally.

DIY knife sharpening devices: drawings and recommendations

To make a sharpener from a washing machine motor with your own hands, you can limit yourself to a motor from an old Soviet design, for example, SMR-1.5 or Riga-17. A power of 200 W will be enough, although you can increase this figure to 400 W by choosing a different engine option.

The list of parts needed for a DIY sharpening machine includes:

tube (to grind the flange);
a nut for fixing the stone on the pulley;

metal for making a protective casing for a sharpener with your own hands (thickness 2.-2.5 mm);
whetstone;
an electrical cable cord having a plug;
starting device;
a corner made of metal or a block of wood (for the frame).

The diameter of the flange must match the dimensions of the bushing on the motor. In addition, a sharpening stone will be placed on this part. On one side, this element is threaded. The indentation should be equal to the thickness of the circle multiplied by 2. The thread is applied with a tap. On the other hand, the flange must be pressed onto the motor shaft using heat. Fixation is carried out by bolting or welding.

Helpful advice! The thread should go in the opposite direction relative to the direction in which the engine rotates. Otherwise, the nut securing the circle will unwind.

The working winding of the motor is connected to the cable. It has a resistance of 12 ohms, which can be calculated using a multimeter. The starting winding for a DIY knife sharpener will have 30 ohms. Then the bed is made. It is recommended to take a metal corner for it.

Some people need . You can make such a design with your own hands from a frame with 3 supports, two spindles, stepper motor(2 kW) and pipes used as holders.

Instructions for creating a stationary circular saw with your own hands

Making a DIY table for a handheld circular saw is the most important stage creation of the machine, since this structure will house the main parts of the equipment in the form of:

power unit;
control block;
cutting component;
other components.

The support bed on the hand tool table doubles as a guide for your DIY circular saw. It controls the direction in which the cut is made and fixes the workpiece.

The sawmill is a modification of the circular saw. The only difference is that the disk is located at the bottom. The design of the table for a circular saw with your own hands is assigned the function of a bed. Installed here power unit, block, fixing disk and control system.

At the design stage for DIY circular saw drawings, you should take into account some factors:

The depth to which the material will be cut depends on the geometry of the disk.
The power level of the electric motor - a specific indicator of 800 W will be sufficient.
Control system installation area - the control should be located as far as possible from the disk.
Rotational speed - the minimum acceptable value is 1600 rpm, otherwise color change will occur during the cutting process.

Helpful advice! If the table is made for a manual version of the tool, it is recommended to make the tabletop metal. The metal sheet should be equipped with stiffening ribs at the base.

How to make a circular saw from a grinder with your own hands

First, the tabletop is made from sheet material. Markings are applied to it in accordance with the dimensions of the instrument. Using these markings, cutouts are made to install the saw.

Installation rip fence for a DIY circular saw made from a wooden strip. The element is fixed to the tabletop.
Groove for stop – these elements are formed on the tabletop using the milling method.
Installation of a ruler for measurements - the installation area is located at the leading edge of the cutting element. The ruler will be used to control the dimensional parameters of the workpieces.
Installation of clamps is an additional component for fixing the workpiece.

For a DIY circular saw machine you will need legs. They are mounted taking into account the dimensions of the countertop made of wooden beams with a section of 4x4 cm. Use is allowed. To provide additional stability, stiffeners should be installed between the supports. A control unit is placed next to the workplace. You should not refuse to install RCDs and devices that protect the engine from overloads.

Technology for creating a wood cutting machine

Manufacturing technology of a homemade cutting machine:

Cutting parts from the corner for assembling the frame (total size - 120x40x60 cm).
Frame assembly by welding.
Fixing the channel (guide) by welding.
Installation of vertical posts (2 pcs.) on the channel (bolt connection).
Assembling a frame from pipes for installing an electric motor and shaft at the required angle (45x60 cm).
Installing a plate with a motor at the rear of the frame.
Manufacturing of a shaft equipped with flanges, supports and a pulley (flange protrusion height - 3.2 cm).
Installation of supports, bearings and pulleys on the shaft. The bearings are fixed to the upper frame in recesses made in the plate.
Installation of a box with electrical diagram to the lower part of the frame.
Installing the shaft in the area between the posts. Diameter – 1.2 cm. A bushing should be placed on top of the shaft with the minimum possible gap so that these elements slide.
Welding a rocker arm made from a channel (80 cm) onto a bushing. The size of the rocker arms must be within the following ratio: 1:3. WITH outside the springs must be secured.

Helpful advice! Experts advise using asynchronous motor. This motor is not particularly demanding. For networks with 3 phases, a motor with a power of 1.5-3 kW is required; for single-phase networks this figure must be increased by a third. A connection via a capacitor will be required.

All that remains is to mount the motor on the short arm of the rocker arm. The cutting element is placed on the long arm. The shaft and motor are connected using a belt drive. For the tabletop you can use a sheet of metal or a planed board.

Assembling a drilling machine with your own hands: video on how to make a structure, recommendations

A good drawing of a drilling machine from a drill with your own hands is the main condition for acquiring the necessary tools. To create such a machine, you do not need to use special materials or buy additional components.

Components for the construction of a homemade drilling machine with your own hands:

bed (base);
rotation mechanism (drill);
device for supplying;
vertically located rack for fixing the drill.

In mastering the technology of making a drilling machine from a drill with your own hands, video material can provide invaluable assistance.

Guide to creating a drilling machine with your own hands (how to make a simple design):

For the rack, it is better to use DPS to make the part massive or a furniture board with a thickness of more than 20 mm. This will eliminate the vibration effect of the tool. You can use the base from an old microscope or photo enlarger.
The accuracy of the drilling machine from a drill with your own hands depends on the guides (2 pcs.). They serve as the basis for moving the block on which the drill is located. To make guides, it is best to take steel strips. Subsequently, they will be securely screwed to the rack.
For the block you need to take steel clamps, thanks to which the rotation mechanism will be securely fastened to this part.

A self-made mini drilling machine requires a rotary tool feeding mechanism. Classic scheme The design involves the use of a spring and a lever. The spring is fixed between the block and the stand.

There are many DIY devices; video material will help you understand this topic.

Features of DIY CNC milling machines

Software is considered an important component in a DIY wood CNC router. Drawings of a conventional design, taking into account this condition, must include additional elements for it:

LPT port;
CNC block.

Helpful advice! To make your own copy-milling machine for wood or metal, you can use carriages belonging to an old printer. Based on these parts, you can create a mechanism that allows the cutter to move in two planes.

Assembling a wood milling machine for a home workshop

At the first stage, drawings are drawn up for a wood milling machine with your own hands, which include information about the placement of all structural components, their dimensions, as well as methods of fixation.

Next, a support frame is assembled from pipes pre-cut into parts of the required size. For fastening you need to use a welding machine. Then the dimensional parameters are checked in order to begin manufacturing the working surface.

You need to act within the following scheme:

Markings are applied to the slab and a tabletop is cut out of it.
If the cutter will be placed vertically, you need to make a cutout for it in the slab.
The spindle and electric motor are being installed. In this case, the spindle should not extend beyond the plane of the working surface.
A limit bar is installed.

Be sure to test the machine before work. When the router is turned on, it should not vibrate too much. To compensate for this drawback, it is recommended to additionally install stiffeners.

Assembling a metal milling machine with your own hands

Step-by-step instructions for making a homemade metal milling machine:

The column and frame are made of metal channel. The result should be a U-shaped structure, where the base of the tool acts as the lower cross member.
Guides are made from the corner. The material must be sanded and connected to the column with bolts.
Guides for the console are made from a profile pipe with a square cross-section. Here you need to insert pins with screwed threads. The console will be moved using a diamond-shaped car jack to a height of 10 cm. In this case, the amplitude to the side is 13 cm, and the tabletop can move within 9 cm.
The working surface is cut out of a plywood sheet and fastened with a screw. The fastener heads need to be recessed.
A vice made of a pipe with a square cross-section and a metal angle welded together is installed on the working surface. It is better to use a threaded pin as a fixing element for the workpiece.

Note! It is better to secure the rotating element in the frame so that the spindle is directed downward. To fix it, you need to weld the jumpers in advance; you will need screws and nuts.

After this, you need to attach a cone (Morse 2) to the spindle and install a collet or drill chuck on it.

Features of making a thicknessing machine with your own hands

Do-it-yourself thicknesser drawings with a complex design involve the use of expensive components:

bearings with increased wear resistance;
rolled steel sheets;
cog;
pulleys;
powerful electric engine.

As a result, production costs homemade surface planer increase significantly. For this reason, many try to limit themselves to the simplest design.

Instructions for homemade thickness planer on wood:

Assembling a thickness planer from an electric planer with your own hands

To create a homemade thickness planer, you need to place the plane on the block, secure it with a device such as clamps, not forgetting to leave a gap.

Note! The gap size is set taking into account the thickness of the workpiece that will be processed on the machine.

The scheme for making a surface planer from a plane with your own hands is very simple:

the support beam is fixed on a convenient surface;
the required gap size is selected by adding layers of plywood;
The surface planer structure made from an electric planer is attached to the resulting base with clamps.

Two clamps hold the base on the table, the other two hold the plane. After making sure that this fastening is secure, you can start using the tool.

Scheme for creating a wood grinding machine with your own hands

The optimal width of the sanding belt is 20 cm.
The sanding cloth of the tape is cut into strips.
Sticker abrasive tape performed end-to-end.
To strengthen the seam, you need to place dense material underneath.
It is not recommended to use low-quality glue, as it will cause the material to tear along the seam.
The diameter of the tape shaft in the center should be 2-3 mm wider than at the edges.
To prevent the tape from slipping, it is recommended to wind it with thin rubber (a bicycle wheel).

Calibrating and grinding machines for wood belong to the group of drum structures. This category is broad and includes many varieties of equipment.

To make a drum sanding machine for wood with your own hands, you can choose the following designs:

surface grinding – the workpiece is processed within one plane;
planetary - with its help a flat plane is formed on the workpiece;
cylindrical grinding – it is used to process cylindrical workpieces.

From the video below, you can learn how to make a grinding machine with your own hands.

Rules for operating a wood jointing machine with your own hands

In the designs of a hand-made jointing machine, it is very important to correctly set the equipment settings so that errors do not exceed the permitted values:

perpendicular – maximum 0.1 mm/cm;
plane – 0.15mm/m.

You can familiarize yourself with the technology of making a jointer with your own hands using a video.

If during operation a mossy or scorched effect appears on the treated surface, it means the cutting elements have become dull. To make processing parts with dimensions less than 3x40 cm more comfortable, they need to be held using pushers.

The curved surface of the workpiece after processing indicates that the correct placement knives and work surface. These elements need to be set again.

All of these machines can be useful for home renovations or basic repairs. Therefore, their presence in the home workshop will be useful. Regardless of how the garage is equipped, all machines require careful and attentive handling. You should never forget about safety while working.

An electric drill is a compact, lightweight, easy-to-use and transport machine. It is indispensable in the home workshop, garage and construction site. In addition to drilling operations, it can be adapted to perform turning, milling, grinding and other work. Many craftsmen use drills to create homemade machines and devices for the home workshop. They are used in the garage for simple wood and metal turning work.

Workshop equipment

It is not always possible to drill an exact hole using a hand drill. If such a need arises, use a stationary drilling machine. It is certainly accurate and safe, which is what you need when processing solid elements with a drill. large diameter.

You rarely see such a machine in a garage or workshop, mainly because of the price; it is expensive, in addition, it is bulky, takes up a lot of space, and is rarely used. The drill on a tripod is a lightweight, easy-to-transport design that will fulfill all the requirements for a desktop drilling machine.

Stationary drilling device

A homemade machine based on a drill will ensure high drilling accuracy in any conditions - it can be installed on a workbench tabletop or on the floor. It consists of several elements. The main ones, of course, are the base and the column. The first part is responsible for the stability of the machine installed on a flat surface. The second, in turn, allows you to smoothly and very accurately move the drill up and down while drilling.

The steel column does not deform even under the greatest pressure to ensure perpendicular drilling. In addition to high accuracy, it is worth mentioning operational safety. If the workpiece is securely secured in a vice on the workbench, then there is no risk of injury during drilling.

Benchtop drill-based machine enables precise drilling of holes in parts complex shapes, for example, round, oval, and also at an angle of 90 degrees. A home craftsman cannot do without it, where the tool is not used intensively. To make a desktop vertical drilling machine based on a drill, you can use ready-made stands or tripods. They are quite suitable for use.

As the manufacturer guarantees, the stand for vertical drilling useful wherever there is a need to perform drilling operations during repairs metal structures, wooden parts. The product is made from quality materials, provides stability and reliability of fastening, due to which the quality of work is good. This type of product is great for reducing work time.

In private garages you can find homemade machines, where tripods from photo enlargers and overhead projectors, jacks and car steering racks of a suitable design are used as a stand for the drill. There are machines made entirely of wood. A drill is a universal mechanism with which you can construct homemade woodworking machines.

Woodworking Machine

Using a drill as electric drive, you can assemble homemade machines and accessories for the garage. For example, a wood lathe in a few days from a board and a handful of screws. Nobody makes drawings for making machines, everything is created according to an invented project.

In addition to homemade drilling and turning equipment for your home workshop, you can make your own milling machine on wood. For the drive, you can choose an electric drill or a hand router.

Bed for grinder

The grinder, like the electric drill, quickly entered our lives and took the place of a universal tool. It can be used to cut pipes, sheet metal and rods, stone and tiles, grind and polish. It has found wide application in car service centers when repairing car bodies. For ease of use, you can make a cutting machine.

To make it cheaper and easier, they make it from wood. As in every machine, the base is made, the material can be chipboard measuring 400 x 400 x 20 millimeters. From below, attach the legs in the form of two slats 40 x 40 millimeters to the slab with screws. Attach a block 100 millimeters high and 50 millimeters thick to the top of the slab. A door hinge with a long plate is attached to the block with screws. The grinder is attached to the plate using a clamp. All, homemade device for a home workshop, acting as a cutting machine is ready. For safe work A machine vise is installed on the base.

Garage sharpener

Emery, electric sharpener, sharpening machine - this is what the tool is called, without which a workshop, a private garage, and a car service center cannot do. The sharpener is the most necessary tool for car repairs, making plumbing products, sharpening tools, and polishing metal surfaces of crafts. No need to buy this one useful mechanism, it is quite possible to get by with a homemade product based on an electric drill. First you need to choose a place on the table and use two wooden brackets 40 millimeters thick and two screws to secure the drill.

To support your hand or tool, you need to make a rest. To do this, you can use thick-layer plywood 20 millimeters thick. The tool rest is attached to the table and placed under the emery wheel. In order for the chips to fall freely on the floor and be able to use sanding wheels different diameters are cut into the tool rest rectangular hole slightly wider than the thickness of the abrasive tool. To adjust the hand rest different heights it is necessary to install a set of plywood plates and secure them with screws. Cover the upper plane of the tool rest with a steel plate. That's it, the useful power tool for the home is ready for use.

Milling machines

There is an opinion among woodworking experts that a router is the most necessary tool for a carpentry workshop. It can even replace some power tools, e.g. circular saw, drill and even jointer. There are two main types of routers:

submersible;
edge

The plunge cutter works as follows: the cutter is immersed in the material and moves along a given contour. The edge cutter does not allow the cutter to be immersed; its milling depth is set in advance and fixed. Based on power, milling cutters are divided into three categories:

small from 500 to 1200 watts;
average from 1100 to 1900 watts;
powerful from 1900 to 2400 watts.

Low-power milling cutters are lightweight, compact, maneuverable, easy to use and allow you to perform all the tasks of a home workshop - this is the best choice for the home. True, low power imposes its limitations. The device works with cutters with a diameter of up to 32 millimeters, there are restrictions on length. If you need to make boxes and frames, this machine is quite enough.

Using an electric drill or a router, you can make a useful attachment for a power tool with your own hands - milling table. This device will come in handy if you have to make profile products from wood. For these purposes, you can adapt an ordinary table by strengthening the tabletop sheet metal two millimeters thick.

A router is attached to the tabletop under the table. A thrust board is installed on the table, which moves under set size and is fixed with clamping bolts. The cutter feed mechanism is a lift, made from a regular car jack, which is installed on metal brackets under the table. The finished homemade product is pleasing to the eye.

By changing cutters you can perform various milling jobs. In general, the device is a professional wood milling machine for the home workshop. It is convenient to select grooves, mill quarters on frames, and process the configuration of skirting boards.

An electric drill, an angle grinder, a hand router are tools on the basis of which you can create devices and multifunctional machines, greatly facilitating the work of the home craftsman.

Homemade machines and devices for the home workshop.

The master came up with a new machine design based on a washing machine engine, which is more functional than its analogues. Several interesting solutions were applied during the work and in the final design.

For homemade work you will need a profile pipe, a sheet of plywood, a section of water pipe, a bearing, a pin, and pulleys. At first I wanted to install a 420 watt motor, but later replaced it with a 300 watt motor, which is sufficient for this design with pulleys.
The frame is in the shape of a parallelepiped.
The master decided to install a large diameter grinding disc - 45 cm - to increase the functionality of the machine.
This machine has more capabilities.

A few comments.

Nils Forsberg
Maybe I’m a fool, of course, but I don’t understand why people use disc sanders, why not a belt sander? On the plate, in different places on the disk, the sandpaper moves at different speeds, which is why it is almost not used near the center, but vice versa at the edge, then again cutting it into a circle means loss of material, a lot of glue is used for gluing, etc. With a belt sander, the speed is the same everywhere, whether in the center or along the edges, it is more economical in terms of sandpaper consumption, in terms of glue consumption, and in terms of wear resistance it is much better because You can glue the tape at least 3 meters or even more. It’s possible that the engine for a tape machine needs a more powerful one, but the benefits are undeniable.

super. One note, there is no need to weld the assembly with bearings. Welding current passes through the balls, can spark through them and the service life of the unit is noticeably reduced. At least the return wire should be connected to the pipe itself, and not to the axle. Otherwise - handsome!

Vladimir
I watched it with pleasure. A lot of witty solutions! I would order the bearing housing from a turner, but then I sawed the pipe, pressed it, welded it and everything was ready! Subscribed to the channel. I hope to learn a lot.
And the editing of the video pleased me! I'm tired of people explaining “twice two” for an hour!

Machines and devices from a simple drill

It is difficult to do without mechanization and automation, having only hand tools. However, a drill is such a universal tool that even when there are no machines in the workshop, using simple devices With just one drill, you can greatly increase productivity and ease of use and save not only time, but also money.
Watch 5 homemade drills at once in a short review video of the DaBRO video channel.
Recommended video.

Another DIY that's worth having in your home workshop if you have a drill and don't have a separate sanding and polishing machine.

Drill holder

It is fixed on a workbench, like a meat grinder.

A drill with such a clamp works as a grinder or

polishing device.

Thank you for watching!

A machine was created based on a large spring

A great and simple idea to make working with a hand-held circular saw more convenient, safer, faster and more precise. The master fitted a large spring. The solution is universal and suitable for grinders and other tools.
I made a platform for the machine.

Attached the door hinge to a circular saw.

Attached to the platform.

I set the sawing guide at an angle of 90 degrees, but you can vary the angle if necessary.

I installed the strut and securely secured the spring.

This is what the finished installation looks like.

The spring works as a return mechanism.

The idea of the author of the video channel Mr. Make Deswal: https://www.youtube.com/watch?v=Z8Ol2Djo5KU

The idea of a simple cutting machine clamp made the job go faster.

An interesting and very convenient clamp for quick work on cutting machine metalworking is used by a master. Usually, not very convenient clamps are used, with which it takes quite a long time to fix the part. Gets lost work time and energy. The clamp is installed on the machine platform. Dimensions of the device for clamping metal and other workpieces. The video will begin immediately with a demonstration of the operation of this device. It is also shown how to make a machine and its attachment.

Each master strives to equip his area as much as possible, to saturate the workspace with machine tools and devices. Homemade machines and devices for the home workshop are of great benefit for running a private household.

Among the homemade household crafts and equipment are:

joinery;
Workbench;
stool;
shelves;
racks.

Crafting table

Workbench dimensions

The height of the tabletop surface must be such that a worker can operate tools and equipment while standing. The workshop owner determines the height of the workbench himself - according to his height. The height of the desktop ranges from 75 cm to 80 cm.

The size of the countertop is determined by the area of the utility room. The table should not impede free passage around it.

Workbench material

Tree
A wooden table is often used. The workbench is made of timber and boards. The legs of the table are secured with diagonal crossbars for reliability.

The table top is made in the form of a shield from knocked down boards using pieces of timber. The shield is rested on the legs of the table and fastened with nails or screws. The connection parts are made from angle steel.

Assembly options wooden workbench They are different, but they have one thing in common - the design of the table must be stable and withstand static and dynamic loads.

If the surface of the workbench will be subject to accidental impact from cutting and sharp tools, then the tabletop is covered with tin or a metal sheet is placed on top.

Metal
The most reliable design desktop is a workbench welded from a metal profile. Manufacturing a welded product requires having a welding machine and experience working with it.

The supporting frame and table legs are welded from steel angle and strip. For auxiliary parts, pieces of reinforcement are used.

The table top is made of metal sheet, 8 - 12 mm thick. A thick sheet will significantly increase the weight of the workbench, which will make it difficult to move.

Stool

Making a stool with your own hands is quite simple:

4 supports, 50 cm long, are made from timber 40 x 40 mm.
The legs in the middle of the length are fastened with crossbars.
Grooves are made in the supports using a chisel.
At the ends of the transverse planks, protrusions are cut out using a chisel to fit the grooves.
The protrusions are lubricated with wood glue and inserted into the grooves.
While the glue dries, the supports are tightened with a belt.
The seat is cut out with a circular saw from wide board 30 mm thick.
A seat measuring 300 x 300 mm is nailed or screwed to the legs of the stool.

Shelves

Shelves are made from boards, chipboard or MDF. They can be open or with side walls. For fastening, furniture hinges are used.

Holes are drilled in the wall into which dowels are driven. The screws are not screwed into the dowels completely so that the hinges of the shelf can be placed on them.

The hinges are screwed to the back of the shelf. The shelves are hung on the wall by placing the hinges on the heads of the screws.

Shelving

Racks are a whole complex of shelves different sizes. They are good to make from chipboard. The lattice structure is supported on a pedestal or simply placed on the floor. For stability of the rack, corners are screwed to the sides of the furniture. Free shelves of corners with holes are nailed to the wall with dowels.

Vertical tool holders

Every craftsman strives to organize his workplace so that the tools are at arm's length. This is facilitated by vertical holders.

Wrench holder

A wooden plank is attached to the wall above the workbench. The rail is screwed with screws into dowels installed in advance.
Small nails are driven into the strip at intervals equal to the width of the wrench handles.
The keys are hung on the rail.
Nail heads hold keys horizontally and vertically.

Screwdriver holder

In a piece of timber 40 x 40 mm, holes are drilled corresponding to the diameters of screwdrivers, at a distance of 30 - 40 mm from each other.
A piece of timber is nailed to the wall with dowels so that the holes are located vertically.
Screwdrivers are inserted into the resulting sockets. Now you can quickly get it the right tool without leaving your workplace.

Chisel belt

The plank is secured to the wall with dowels.
The belt or belt is nailed to the bar so that unique through pockets are obtained.
Chisels are lowered into the pockets, through which only steel blades pass. The handles are held in place by a belt.

The device can hold hammers, pliers, pliers and other tools.

Homemade soldering iron stand

When working with a soldering iron, a situation arises when you need to put the tool down. Placing a soldering iron with a hot tip on a tabletop or on any object is always risky. Homemade stand will solve this problem.

An example of making a stand for a soldering iron

The holder is made of wire in the form of a spiral. To do this, unbend a wire clothes hanger.
The wire is wound around a cylindrical object with a diameter of 1.5 - 2 cm. The handle of a chisel or other tool will do.
On one side of the spring there is a free end of the wire.
The end is bent into a loop with pliers.
For the base of the stand, take a board 200 x 100 x 20 mm.
A through hole ø 4 mm is drilled at the base.
A hole is drilled from the back of the board with a large drill for a countersunk screw head.
The screw is threaded from bottom to top.
Place the spring loop on the screw and tighten the nut.
Circles are cut into the board using a crown to fit the size of a cup for candles or similar products.
Using a chisel, make a sample of wood in 3 recesses.
Cups are inserted into the openings, which are filled with solder, tin and a napkin to clean the tip.
The soldering iron is inserted into the spring.
A small hole is made in the board for attaching a flexible steel cord from a lamp.
A clamp is attached to the end of the cord, which is used to secure various parts for soldering.

The design may have a different look - it all depends on the imagination and ingenuity of the author.

The simplest mousetrap in the world

This name can be assigned to many homemade mousetraps, invented by craftsmen. They have one thing in common - humane treatment of animals caught in a trap. The device does not kill the animal, but isolates it. A few examples of how to make a simple mousetrap:

Plastic funnel

Cut a plastic 3 liter bottle in half. The cut neck is turned over and inserted into the bottom of the bottle. Bait (seeds, grain, etc.) is poured onto the bottom.

The trap is placed close to an object that the mouse could climb. A rodent, having fallen into a funnel, can no longer get out of the bottle.

Console

The design is a tilting platform. It is made from a piece of cardboard or plastic. The bar is placed on a plane so that half of it hangs in the air.

The bait is placed on the edge of the console so that the bar is on the verge of balance. The animal, having reached the bait, overturns the bar and falls along with it into the substituted bucket.

Suspension

An empty plastic bottle with bait at the bottom is placed on the edge of the table. A cord is attached to the neck by piercing the plastic with a hook made from a paper clip. The other end of the cord is tied to some support.

The mouse, attracted by the smell of food, enters the container. The bottle tips over under the weight of the rodent and hangs on the cord.

Mini vise made of metal loop

When performing small operations, small parts often need to be clamped. To do this, use a mini vice made from a one-piece door hinge.

Matching holes are drilled in both hinge flaps.

A bolt of suitable diameter is threaded through them. On the other side, a wing nut is screwed onto the bolt thread. The parts are inserted into the opening between the doors and clamped by tightening the nut. The device can be used as a clamp.

Portable beer box

A box for drinks in glass containers is a convenient device for carrying several bottles at once at the cottage or on a picnic. To make such a box with your own hands, you will need the following tools and materials:

Tools

jigsaw;
wood saw;
sander;
drill-driver;
drill;
hammer;
chisel;
feather drill.

Materials

edged board – 1050 x 170 x 15 mm;
fruit box slats - 5 pcs.;
handle ø 36 mm and length 350 mm;
stain;
screws;
nails.

Step-by-step instructions for assembling the box

The edged board is sawn into three identical parts (bottom and two sides), each 350 mm long.
Two boards are cut with a jigsaw so that the sides taper from the middle and end in an oval top.
At the tops of the sidewalls, holes ø 36 mm are drilled with a feather drill.
All wooden parts clean with a grinder and an emery wheel. The cuttings are sanded manually with emery.
Using a thin drill, drill 4 holes along the edges of the bottom. The nests of holes are countersinked from below.
The sidewalls are installed on the sides of the bottom. Screws are screwed into the bottom of the bottom. The heads of the screws are “hidden” in the sockets of the holes.
Two strips are nailed to the sides with nails on each side of the box. They will become a vertical fence for bottles.
Cuts are made in three planks so that by folding them, you get a sheathing with square openings for glass containers.
The sheathing is laid on the bottom between the sidewalls.
The nails are nailed in those places where the ends of the sheathing rest against the sidewalls and fencing strips.
A ø 36 mm handle is inserted into the holes in the tops of the sidewalls.
Driving the nails in at an angle, fasten the sides to the handle.
The entire surface of the box is treated with stain.

The box is ready for use. The portable container can easily accommodate 6 bottles of beer or other drink. The crate's lathing and guards will prevent bottles from breaking or falling out while being carried.

Hammer upgrade

A common occurrence is a wooden handle falling out of the hammer socket. One way to create reliable fastening handles - a cut is made at the upper end of the handle. The holder is inserted into the hammer socket. The cut is filled with Moment glue. A wooden wedge is driven into the groove.

In order not to look for nails while working, and especially not to hold them with your teeth, a round magnet is glued into the bottom of the hammer handle. Magnetic nails will always be at hand for the worker.
It is dangerous for the hammer to accidentally fall out of your hand at height. To prevent this from happening, a hole is drilled in the handle through which the cord is threaded. The worker's belt is threaded through the loop.

Homemade tools and machines

Pipe bender

Bending device metal pipes It is a metal rod welded to the frame. I make the rod from a piece of reinforcement. The pipe is placed on a pin, and on the other side a long piece of reinforcement is inserted into the pipe. By pressing the lever, the pipe is bent at the desired angle. The device is suitable for small sections of round pipes.

Device for bending profiled pipes

Greenhouse owners know how important it is to have a device for bending long lengths of profile pipe. The curved profile is used as an arched structure for the formation of polyethylene coverings for greenhouses.

Pipe bender allows you to save considerable cash on the construction of a greenhouse. The design consists of 3 rollers - two are guides, and the third roller performs the leading function.

The profile pipe is inserted into the opening between the two wheels and the roller. The roller has a stop and a rotating device in the form of a lever or an electric motor drive.

Making a pipe bender with your own hands

Two axles are welded to a metal frame from pieces of smooth reinforcement, onto which old car hubs are placed.
Protruding chamfers are removed from the hubs to side surfaces the rollers were smooth.
The channel is placed in the opening between the hubs with the shelves facing up.
The same profile, smaller in width, with the flanges down, is placed into the channel.
An axle is welded to the top of the inner profile, onto which the third hub is placed.
A vertical shelf made of steel sheet is welded to the frame.
A hole is cut in the vertical bar and the bearing is pressed into it.
A nut is secured to the middle channel by welding.
One end of the screw rod is screwed into the nut.
The screw shank is threaded through a bearing in a vertical bar.
A rotary handle is welded to the shank on the back side of the bar.
A swing arm is welded to the axis of the drive hub.

The machine is ready for use. A profile pipe is inserted between the rollers and clamped with a screw. The rotary lever drives the rollers, which pull the pipe, bending it. The bending radius is set using the rotary handle of the screw.

Pipe bender from car hubs- one of the device options. There are many designs of bending devices. In some models, the drive roller is coaxially connected to the motor shaft.

Impact screwdriver from starter

There are situations when it is impossible to unscrew a rusted bolt or screw with a conventional tool. An impact screwdriver does this job perfectly. The tool is made by hand from parts of a car starter:

The shaft and bushing are removed from the starter housing.
Part of the shaft is cut off, leaving a splined rod.
A piece of pipe of suitable size is placed on the sleeve.
A piece of bolt of equal diameter is welded to the end of the pipe.
The end of the shaft is ground into a tetrahedron shape onto which the heads are placed the right size. For screws, a bit is inserted into the head.

When you hit the head of the bolt with a hammer, the shaft slides with beveled splines inside the sleeve, making rotational movement. The stronger the blow, the more force the shaft rotates.

Homemade circular saw machine

A do-it-yourself cutting machine made from an angle grinder is not inferior to some factory-made samples. The grinder is a fairly powerful hand-held circular saw.

The grinder-based machine performs precise cuts of lumber and metal profiles. To make it you will need the power tool itself, a welding machine and a metal profile.

Step-by-step instructions for assembling the machine

Two metal strips are welded to the pipe section, in which mounting holes are drilled.
Accordingly, two holes are also made in the casing of the angle grinder.
The strips are bolted to the casing.
The machine bed is made from a metal sheet with support corners welded to the bottom.
A vertical section of a corner is attached to the frame by welding, in which a hole is drilled.
A piece of angle is welded to the lower end of the lever and drilled through along with the pipe.
The bolt is threaded through the holes and the hinge connection of the vertical post with the lever is tightened with a nut. Additionally, install a lock nut.
In a vertical position, the angle grinder lever takes a stable position.
At the point of contact saw blade a cut is made with the bed so that the disc can completely cut the workpiece.
The handle of the power tool is moved to the end of the lever.
As additional devices, a transverse and angular stop are installed on the frame.

If necessary, remove the power tool from the machine and use a circular saw in manual mode.

Homemade bow saw

A bow saw is a convenient tool for cutting tree trunks and lumber. The design of the saw is simple, make hand tool easy to do with your own hands. To do this you need to prepare tools and materials:
