Homemade tabletop machines. Home workshop: homemade carpentry machines and equipment

If a person often faces the need to make something from wood, simply loves to do it, or produces things to order, then he simply needs a machine. It is not only expensive to purchase such things, but they also do not always fit in size, may be uncomfortable or do not fit into the design. But a homemade machine with your own hands, made to the required dimensions, will fit perfectly into the space of the room and will always be comfortable.

Engine

If you have decided to manufacture this device yourself, then it is important to choose the right components. For example, in order to design, you will definitely need an electric motor. This part can be of several types.

The first type of motor that can be used when making a machine with your own hands is an asynchronous one. The advantage is that it requires no maintenance and will also allow you to work with a larger cutter. Among the shortcomings we can highlight a large number of the noise the engine makes when running. However, this is a purely individual question.

Commutator motor. This option is somewhat worse than the previous one, for the reason that over time and the work of the part, its brushes wear out and have to be replaced. The more and more intensively the engine is used, the more often the brushes will have to be changed.

Engine power

Choosing the type of engine for a homemade machine with your own hands is not all. You need to pay attention to the power of this element. This is a very important indicator.

Machines with power up to 0.5 kW are best suited for surface processing of material. It is worth adding that only the softest types of wood can be processed on such a machine and only small cutting tools can be used.

The second type of engine power for a homemade do-it-yourself machine is 1.2 kW. As practice shows, this indicator is the most universal and in demand. This power is quite enough for deep wood processing. For home use 1.2 kW is quite enough.

The last type of power is up to 2 kW. Most often, such machines are already semi-professional. They open ample opportunities for wood processing, they allow you to use almost any type of cutter, as well as process some types of plastic and soft metal - aluminum.

Speed ​​and power supply of the workbench

If we talk about the number of revolutions for a homemade machine with your own hands, then everything is quite simple and clear. The higher the numerical value of this characteristic, the cleaner and more efficient the final processing of the wood part will be. However, there is another small plus. If the speed is high enough, then such an engine is not afraid of wood defects such as knots. The cutter will pass them without any problems.

With nutrition, everything is also quite simple. Most often, those engines that are powered by 220/50 are selected. Installing and connecting this type of motor does not cause problems. Several more difficulties arise when connecting elements with three-phase power.

Workbench and frame for the unit

A do-it-yourself woodworking machine must have an element such as a workbench. The choice of its size should be based on what parts will have to be worked with in the future. Dimensions of the table on which all this will be mounted: special significance Dont Have.

The frame for the machine must be selected so that it is not only very durable, but also can withstand dynamic loads. The main difference between a self-assembled electric woodworking machine and a manual one is that the device itself will not move, but the workpiece will have to be actively moved. WITH practical point In my opinion, using wood for a machine frame is not a good idea. This is due to the fact that over time the wood dries out, becomes cracked and loses its strength. The best option would be a metal pipe that has a square or rectangular profile.

Tabletop

When choosing this element, everything is exactly the same as with the frame, but vice versa. Metal will not be the best choice in quality source material for two reasons. Firstly, the tabletop will turn out to be very massive and will have a too rough appearance. Secondly, you will have to use welding to secure everything securely.

It is best to use one of the following three materials:

• planed boards;
• chipboard boards, OSV;
• multilayer plywood.

The material for the countertop must be quite durable to withstand subsequent loads. For this reason, the thickness and material for the manufacture of this element must be selected based on what work will be carried out in the future. Another one important detail- This smooth surface table. If you do not follow this recommendation, you will not be able to make an accurate cutter. If it is important to assemble a homemade machine with your own hands so that it can be used to produce workpieces of decent quality, then this is one of the most important conditions.

In order to ensure a perfectly flat surface, you can use methods such as lamination, upholstery with sheet iron or precise adjustment of planed boards.

How to make a machine with your own hands

The assembly procedure for this device begins with the need to determine the location of the engine. The best option Installing this element under the table is considered. A cutter is placed on the motor shaft, which should be directed vertically upward. In order to facilitate the assembly procedure, it is best to make a drawing of the machine with your own hands, on which all the parts were depicted in advance.

It's all about money. Metal lathes are very, very expensive things, this applies to even the simplest models.

Making this kind of machine with your own hands is something anyone can do, which is why many home and handicraft craftsmen build these devices on their own and are very successful.

A lathe is an ancient device; it is an early device for processing a wide variety of parts from a wide variety of materials - from metal to wood, etc.

Processing is, first of all, turning surfaces both inside and outside, drilling and boring holes of different diameters, cutting threads, and forming surface relief using knurling.

Speaking of turning metal parts, then industrial turning devices produced by different factories are expensive and massive units, which are very difficult to operate.

They in no way relate to desktop devices, these are serious industrial units, which in principle are not suitable for handicraft work. Therefore, a homemade lathe is a great idea for all reasons.

Drawing of a lathe.

You can, for example, make it in the form of a mini version, which will be quite enough for processing both metal parts and workpieces made of any other materials.

There are certain limitations when using homemade mini-machines: they are designed mainly for working with round parts, with sections such as axles, handles for tools, wheels, etc.

In mini-machines, parts need to be fixed only in a horizontal position for their rotational movements. Excess material during turning is removed by cutters, which are fixed in the support of the lathe.

Components of a mini metal lathe

Composition of any turning device traditional, all of the following elements are present regardless of how it is made - manually at home or industrially.

The devices consist of the following components:

bed

The main load-bearing element of the entire structure, giving it rigidity and strength. The bed of a homemade lathe is made from wooden beams or metal blanks in the form of ready-made corners.

The main requirement for the bed is the necessary strength, since the structure of the machine is exposed to strong vibration during the processing process.

Drive unit

The main element of the part responsible for the power of work. The drive must be selected very correctly based on the power required. This is not an easy task and one that needs to be thought through carefully.

A used washing machine drive will suffice, construction mixer or anything else if you are making a lightweight metalworking machine.

The number of revolutions with such drives is about 1500 rpm, and the power is 200 W or slightly higher.

1. Tailstock.
   This is a special steel plate to which a steel corner is also welded. It is needed for tight fixation of the workpiece to the bed for high-quality processing.
2. Headstock.
   This is the same part as the tailstock, but unlike the front one, it is fixed on the movable frame of the device.
3. Front and back centers.
4. Caliper.

This is one of the key factors for the working elements of the device, information about which you can read below.

How is rotation done?

Device lathe.

Torque is generated in the machine different ways. You can install the working part on the rotary shaft electric motor directly. This approach will save a lot of things: both space and money for spare parts.

Unfortunately, such an arrangement is not always possible, so the so-called gears are appointed as the main executor of the rotational movement. They come in chain, belt and friction types.

Each type of transmission has its pros and cons:

Belting

Most a budget option motor transmissions with many advantages. The main one is reliability. Making a belt drive is simple: most often craftsmen take one from other devices.

There is also a drawback - this is its fragility, since the belts wear out quickly. You will have to change them quite often.

Chain and friction transmission

A chain drive is not cheap, and it is also much more bulky than a belt drive. But such a transmission will last much longer, so you will get “strategic” cost savings. The friction drive is located exactly in the middle between the belt and chain drives.

Main components of the device

The final quality of the processed part depends on the support. The effort, time and all other resources invested in the process can go down the drain without a well-established support. This part is located on special “sleds” moving along the frame along guide vectors.

The movement of the caliper can occur in the following directions:

• Longitudinal movement in which the working element of the device moves along the part being connected. This direction is performed when turning a circular thread or to remove the surface layer of paint or something else from the workpiece being processed.
• The transverse movement of the caliper is perpendicular to the axis of the part. With the help of this movement, holes and recesses are made.
• The inclined movement can be carried out at various angles of inclination, it is used to produce surface recesses of various configurations.

It should be remembered that the caliper, as the most active and moving part of the device, is the most worn.

Elements of a lathe.

Rapid wear is explained by the action of constant and serious vibration, which results in loosening of the fasteners and subsequent backlash, which always affects the quality of turning work in one form or another. Such a disaster can be avoided; this requires constant adjustment and adjustment of the caliper.

The caliper can be adjusted in different ways. If the backlash is adjusted, it is eliminated using a screw. Gaps can be eliminated using special inserts between the carriage and the guides.

Gaps appear when the screw that controls the longitudinal and lateral movement in planes. Oil seals can also wear out. In this case, they are washed and lubricated until completely saturated with machine oil. Sometimes they just need to be replaced with new ones.

Stages of assembling a lathe

The power level of the motor must be calculated depending on the planned work - the size of the metal parts that you are going to work with on your new unit.

If you plan to work with small parts, a motor with a power of about 1 kW will be sufficient. Such motors are found on sewing machines or other household electrical appliances. If your future parts are larger, choose a motor with a power of 1.5 to 2.0 kW.

The power also depends on the material you are going to work with. If, for example, your material is wood, then do-it-yourself wood lathes, including homemade cutter for wood lathe, high power will not be required.

The most important issue is reliable insulation of all electrical components. The best option would be to consult a specialist. Confidence in the safety of the device and the professional reliability of the design will not hurt you: after all, you are going to work with electricity and metals. And they don't joke with them.

Making a machine from a drill

The drill will look great as a drive to a lathe.

This elegant solution will save you a lot of money and make your life much easier because it has a number of great benefits:

• The modularity of the device: it is simply assembled and disassembled. The drill can be detached from the frame and reattached without any difficulty.
• This model is very transportable, you can work with it anywhere - even in the country, even in the garage.
• Significant cost savings: no need to purchase additional replacement attachments or belt drive.

To assemble a device from a drill, you will need almost the same parts as for a regular device. Only two things will not be needed: an electric motor and a headstock, and these are the most important and most expensive structural elements.

Because the lightweight machine and compact, there is no need to build a stable frame; a workbench or table will be enough. The drill is fixed using a clamp and a clamp.

Design and dimensions of a lathe.

Expanding the functions of a turning device from a drill can be done using additional attachments and other devices. You can make some great homemade woodworking machines.

There are, of course, disadvantages. You will not be able to process parts using a drill machine big size. We can try to improve the model in this direction. For example, add a belt drive to increase the speed.

But the game is not worth the trouble: it will lose its main advantages in the form of simplicity and ease. Thus, homemade apparatus using a drill only makes sense in cases where you are working with small parts.

A lathe made from a drill is capable of many things: it can not only process parts. But also work with paints - apply them to the workpiece while it is rotating. This is also a homemade wood cutting machine.

Winding wire around a transformer and applying various types of notches on the surfaces of parts are just some examples of using a multifunctional machine consisting of a drill and a metal lathe.

And now the simplest machine

Today there are a huge number of drawings, instructions and videos on the Internet on the topic “how to make a homemade lathe”, with the help of which independent work making a lathe is quite realistic and can be done by almost anyone.

You can, of course, take a swing at a mini-machine with program controlled. Or you can stop at the simplest option, which will work perfectly with low costs according to the most various details various configurations.

Wooden posts are attached to the frame using bolts. The frame must be reliable, so it is made of steel corners. In extreme cases, it can be made from bars.

The device of a wood lathe.

The cutting element is fixed on a knot from the tool rest, and it will move along it. A sheet of metal should be tightly fixed on the moving surface to protect the structure from deformation. In addition, this will help position the metal turning tool exactly to the part that needs to be machined.

To make the headstock and tailstock, suitable metal cylinders with the appropriate diameter are selected. They are housed in bearing assemblies that are pre-positioned in wooden posts.

The rotational movement is transmitted through the front center, connected to the motor using a belt drive. The part is fixed between the front and rear sections and processed with a cutter from a tool rest.

There are no problems with finding and choosing an electric motor for a mini-lathe.

We have already written that a low-power motor can be found on any household electrical device, any used home appliance is quite suitable for this task. Can be used as a drive grinding machines or drill.

Safety precautions

Since we are talking about working with metals, the requirements for compliance with safety regulations will be clear and strict, from which there is no escape. The first step is to check the functionality of the new machine immediately after its manufacture.

How to check the performance of the machine: the spindle should rotate without the slightest difficulty. It is necessary to measure the coincidence of the axis of rotation of the parts in the machine with the center of symmetry of the same part. Common axis should be visible at the front and rear centers.

Elements of the design of a lathe.

The electric motor is always covered with a special casing, which protects the motor from dirt and metal particles, as well as the machine operator himself. If your device is made from a drill, no casing is needed.

If you decide to equip your homemade lathe with a powerful motor, be sure to test on your home network to see if it is enough for your powerful motor. In general, it is better to adhere to established traditions and use old friends - electric motors from household appliances.

Making a homemade lathe is an excellent and elegant solution from all points of view. Ease of execution, cost savings, efficient processing of parts - all this is about homemade lathes.

The most popular machines are wood and metal working. Either one would look great in a home workshop. If it weren't for their price. Today we will tell you how to make useful equipment with your own hands.

Wood lathe – bringing the experience of millennia to life in the home workshop

Official history believes that the first woodworking lathe was created in 650. BC e. Over the past millennia, machine tool manufacturing has stepped far forward, and modern devices perform dozens of tasks. However, we are interested in homemade machines and devices for the home workshop.

One of the most popular mechanisms remains the lathe. It is designed to give rounded shapes to wooden workpieces and apply patterns. By the way, some managed to work with them in school labor lessons. Someone remembers its structure, and for others the figure below will help:

Most of the parts have self-explanatory names. But during assembly we will explain what this or that element is responsible for. But because... The machine is homemade, we will leave only the main mechanisms:

• Bed;
• Electric drive;
• Back and front headstock;
• Handyman.

This process begins with drawings:

We will leave the dimensions of the machine standard for factory products:

• Length – 800 mm;
• Width – 400 mm;
• Height – 350 mm.

These dimensions of the device allow you to work with workpieces with a diameter of 250 mm and a length of 200 mm. Of course, the dimensions are not impressive, but this is our first machine. Assembly begins with the manufacture of the frame - the remaining mechanisms are attached to it.

The next element is electric drive. DIYers advise using old electric motors for these purposes. washing machines. Such a drive has acceptable power and a ready-made control device (bolts and fasteners are a bonus). The power plant is mounted on a separate plate and attached to the frame (sometimes they are made detachable).

Headstock – holds and rotates the workpiece. You can make it yourself from a metal sheet or thick plywood. But it is safer to use a factory spindle with several pins. In factory machines it is connected to power plant using a belt drive. We can attach the holding device directly to the motor shaft.

The spindle of lathes is a rotating shaft equipped with a mechanism for fastening workpieces.

Tailstock – serves to support and rotate the workpiece installed in the machine. It is best to use a metal head from an electric drill for these purposes. In the future it is used as self-fixing or for installing a feather drill. The tailstock is mounted on a carriage made of angles or channels that moves along the frame.

By the way, many interesting ideas homemade machines involve the use of old power tools.

The output should be something like this:

WITH drilled iron without leaving home - do-it-yourself milling machine

Along with wooden blanks Metal products are regularly required in the household. To work with it, people have invented many machines: lathes, cutting machines, milling machines, etc. A metalworking lathe is similar to woodworking lathes - the difference is in the margin of safety and power. Cutting machine involves working with iron sheets. But for the average homeowner, a metal saw or grinder is enough for these purposes. But a milling machine is needed much more often. With its help, shaped surfaces and planes are processed and complex hardware(pulleys, rollers, etc.).

Factory price milling machine starts from 10 thousand rubles (usually much higher). But if you have free time, some details and skillful hands, it can be assembled at home. It may not be too powerful or beautiful, but it is functional.

For a home milling machine you will need:

• Electric drill operating from 220 volts (power drive);
• Jack;
• Metal channels, angles No. 25, square tube No. 20;
• Metal rods for axles or threaded rods;
• Plywood 10 mm thick (workbench top);
• Collet;
• Morse taper is a special mount in the machine spindle. It is distinguished by reliability, centering accuracy and allows you to quickly change the tool;
• Locksmith tools, welding machine, fasteners.

As you can see, a visit to a specialized store is inevitable - all kinds of handicraft devices can injure a novice master.

An approximate diagram of the future machine can be seen below:

This drawing is not a standard, but on its basis it is quite possible to develop own mechanism. After preparation necessary tools and sketches, you can start assembling. It begins with the creation of a bed and a column. This is a U-shaped structure laid on its side, where the lower plane is the base of the machine.

The next stage is guides that allow the console to move vertically. For these purposes, use polished corners (No. 25), bolted to the frame. Having finished with the vertical guides, we proceed to the horizontal ones. This will come in handy square pipe– we drill holes in it through which we will pass metal rods with threaded threads (or studs).

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

Workbench material

Tree
Often used wooden table. 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:

1. 4 supports, 50 cm long, are made from timber 40 x 40 mm.
2. The legs in the middle of the length are fastened with crossbars.
3. Grooves are made in the supports using a chisel.
4. At the ends of the transverse planks, protrusions are cut out using a chisel to fit the grooves.
5. The protrusions are lubricated with wood glue and inserted into the grooves.
6. While the glue dries, the supports are tightened with a belt.
7. The seat is cut out circular saw from wide board 30 mm thick.
8. 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

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

Screwdriver holder

1. 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.
2. A piece of timber is nailed to the wall with dowels so that the holes are located vertically.
3. Screwdrivers are inserted into the resulting sockets. Now you can quickly get the tool you need without leaving your workplace.

Chisel belt

1. The plank is secured to the wall with dowels.
2. The belt or belt is nailed to the bar so that unique through pockets are obtained.
3. 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

1. The holder is made of wire in the form of a spiral. To do this, unbend a wire clothes hanger.
2. 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.
3. On one side of the spring there is a free end of the wire.
4. The end is bent into a loop with pliers.
5. For the base of the stand, take a board 200 x 100 x 20 mm.
6. A through hole ø 4 mm is drilled at the base.
7. A hole is drilled from the back of the board with a large drill for a countersunk screw head.
8. The screw is threaded from bottom to top.
9. Place the spring loop on the screw and tighten the nut.
10. Circles are cut into the board using a crown to fit the size of a cup for candles or similar products.
11. Using a chisel, make a sample of wood in 3 recesses.
12. Cups are inserted into the openings, which are filled with solder, tin and a napkin to clean the tip.
13. The soldering iron is inserted into the spring.
14. A small hole is made in the board for attaching a flexible steel cord from a lamp.
15. 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 one is placed on the edge of the table. plastic bottle with bait on the bottom. 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

Box for drinks in glass containers – convenient device for carrying several bottles at once at the cottage or 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

1. The edged board is sawn into three identical parts (bottom and two sides), each 350 mm long.
2. Two boards are cut with a jigsaw so that the sides taper from the middle and end in an oval top.
3. At the tops of the sidewalls, holes ø 36 mm are drilled with a feather drill.
4. All wooden parts are cleaned with a grinder and an emery wheel. The cuttings are sanded manually with emery.
5. Using a thin drill, drill 4 holes along the edges of the bottom. The nests of holes are countersinked from below.
6. 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.
7. Two strips are nailed to the sides with nails on each side of the box. They will become a vertical fence for bottles.
8. Cuts are made in three planks so that by folding them, you get a sheathing with square openings for glass containers.
9. The sheathing is laid on the bottom between the sidewalls.
10. The nails are nailed in those places where the ends of the sheathing rest against the sidewalls and fencing strips.
11. A ø 36 mm handle is inserted into the holes in the tops of the sidewalls.
12. Driving the nails in at an angle, fasten the sides to the handle.
13. 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 loss wooden handle from 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 represents 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

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

The machine is ready for use. They turn on between the rollers profile pipe and tighten it 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 unscrewing a rusty bolt or screw ordinary tool impossible. An impact screwdriver does this job perfectly. The tool is made by hand from parts of a car starter:

1. The shaft and bushing are removed from the starter housing.
2. Part of the shaft is cut off, leaving a splined rod.
3. A piece of pipe of suitable size is placed on the sleeve.
4. A piece of bolt of equal diameter is welded to the end of the pipe.
5. 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 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

1. Two metal strips are welded to the pipe section, in which mounting holes are drilled.
2. Accordingly, two holes are also made in the casing of the angle grinder.
3. The strips are bolted to the casing.
4. The machine bed is made from a metal sheet with support corners welded to the bottom.
5. A vertical section of a corner is attached to the frame by welding, in which a hole is drilled.
6. A piece of angle is welded to the lower end of the lever and drilled through along with the pipe.
7. The bolt is threaded through the holes and the swivel joint is tightened with a nut. vertical stand with a lever. Additionally, install a lock nut.
8. In a vertical position, the angle grinder lever takes a stable position.
9. A cut is made at the point where the saw blade comes into contact with the frame so that the blade can completely cut the workpiece.
10. The handle of the power tool is moved to the end of the lever.
11. As additional accessories, 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.

Step-by-step instructions for making a bow saw

1. The lath is cut into three parts (two vertical side strips and a middle horizontal strip).
2. Grooves are made in the side handles using a chisel.
3. At the ends of the centerpiece, protrusions for grooves are cut out with a chisel.
4. The centerpiece is connected to the side handles.
5. Drill at joints through holes. Wooden cotter pins are driven into them.
6. Cotter pins form hinge joints. This is necessary for the mobility of the lower ends of the side slats when the canvas is tensioned.
7. Cuts are made at the lower ends of the sidewalls - parallel to the middle.
8. In the holes saw blade insert short bolts and tighten them with nuts.
9. The blade is inserted into the cuts so that the bolts are on the outside of the structure.
10. Circular grooves are cut out at the upper ends of the handles.
11. Loops are made at the ends of the double cord, which are placed on the grooves.
12. A handle is inserted between the strings of the cord, the long end of which rests on the mullion.
13. The saw string is twisted using a handle, achieving the desired degree of tension on the saw blade.
14. The wood is covered with stain and two layers of varnish.
15. After the varnish has dried, the saw is ready for use.

If you assemble a homemade metal lathe with your own hands, you can get at your disposal functional equipment for processing metal without extra costs. For objectivity, we will consider not only the assembly process, but also the current offers of the market of finished products. The information presented below will help you make a correct comparative analysis, taking into account financial capabilities, professional skills and other personal characteristics.

A high-quality homemade product is in no way inferior to its factory counterpart.

What you can do with a homemade metal lathe with your own hands

Using a tabletop metal lathe, you can perform various work operations efficiently and quickly:

• processing of ends and grooves with the required level of accuracy;
• expansion of existing holes with conical and cylindrical(countersinking);
• accurate cutting of workpieces according to the length established by the plan;
• creating a relief surface by rolling;
• cutting standard and special threads (external/internal).

To select the required accuracy of movement of the caliper, change the thread pitch of the lead screw. It is cut with a die on a screw cutting machine. To strengthen the structure, connections are made using welding. The headstock bodies are made from channel bars (No. 12/14).

How to choose the right motor for your lathe

The project presented above is designed to be used power unit power 450−600 W with a maximum operating shaft speed of 2500−3500 rpm.

Such solutions are quite suitable if you choose an existing engine of sufficient power.

In order not to be mistaken, you can study examples of factory machines for metal, good luck with your homemade projects. Based on such a mini-research, it is easy to draw a conclusion about the following proportions: to process parts with a diameter of 8-12 cm and a length of 60-80 cm, electric motors with a power of 600-800 W are used. Standard air-cooled asynchronous type models are suitable. Manifold modifications are not recommended. They sharply increase speed when the load on the shaft decreases, which will be unsafe. To prevent such situations, you will have to use a gearbox, which will complicate the design.

One advantage of belt drive should be emphasized. It prevents direct mechanical impact on the shaft from the tool in the transverse direction. This extends the life of the support bearings.

“DC electric motors are large in size. But they can be connected using a relatively simple circuit, which will ensure smooth speed control.”

Assembly order

This algorithm explains the sequence of actions when working with the above drawings. The use of other design documentation implies making appropriate changes to the assembly process.

Start with the front headstock. Install the spindle into it. Next, the entire assembly is connected to the running pipe using bolted fastening. First, threads are cut on the fastening parts. When performing this operation, the alignment of the parts is carefully monitored.

At the next stage, a power frame is assembled from channels. When the frame is made, the headstock is installed on it. Here you also need to pay special attention to the parallelism of the running tube and the long parts of the frame. They make the markings accurately. The holes are drilled sequentially with an additional reamer boring, checking each fastening unit. One or two mistakes will not unduly affect the strength of the channel, so it is better to make a new precise hole in a different place, if necessary.

For your information! Do not forget about installing spring steel washers, which ensure reliability bolted connections in conditions of high vibrations.

When assembling this unit, special attention should be paid to the accuracy of the placement of the central axes of the spindle (1) and quill (2). If a mistake is made, conical surfaces will be obtained instead of cylindrical when processing workpieces. They also check that these elements are parallel to the running pipe. The support bar (3) prevents the tailstock from unfolding. To adjust the height, you can use steel spacers.

The caliper parts are installed sequentially in accordance with the assembly drawing diagram. Here, particularly high precision is not needed, since numerous adjustments are provided. If intensive use is expected, make individual components detachable in order to replace wearing parts without extra costs.

At the final stage, the electric motor is installed and connected to the electrical network according to the selected circuit. Check the functionality of a metal lathe with your own hands in practice. To improve appearance and protect against corrosion, some parts are coated with primer and paint.

How to make a lathe from a drill with your own hands

For , plastic, others soft materials The power of a typical household power tool is quite sufficient. This example shows how to do functional machine with your own hands in 15-20 minutes. Using the last photos in the table, the creation of an improved design is described:

Photo	Assembly sequence with author's recommendations
	A serial drill was used as a basis. It is assumed that relatively small workpieces will be processed. For the bed, in this case, a sheet of plywood is selected, which is fixed to the table. Any other sufficiently strong and level base will do.
	It is necessary to securely secure the power tool in a comfortable position so as not to damage it during operation. This problem can be solved using an auxiliary housing. It is made of thick plywood (20 mm) taking into account the corresponding overall dimensions.
	The individual parts of the structure are fastened with self-tapping screws. An element with a figured cutout is installed in the front part. This socket is created with a shape and dimensions that are suitable for mounting the protruding part of the durable drill body (marked with arrows).
	The base is screwed to the tabletop in the right place. Power tools are installed inside. For rigid fixation, use a clamp. A wooden block is fixed nearby as a support bar.
	The cutter can be made from an old file. A standard grinding machine is suitable for processing this workpiece.
	A strong steel rod is inserted into the cartridge. A wooden blank is screwed onto it.
	Next, check the functionality of the machine.
	If you remove a small thickness with a cutter with each pass, you will be able to process workpieces made of fairly hard materials. The finishing surface is created using sandpaper.
	To process larger workpieces, you can create a machine with a headstock and a tailstock. The photo shows the main structural elements. The power tool is secured securely, but, if necessary, it can be removed for its intended use.
	There is a support with a metal insert (handle) installed here, which helps to move the cutter accurately and accurately.

How can you upgrade a lathe yourself?

The drawings discussed above are a time-tested project. With their help, you can make a functional mini metal lathe with your own hands. But some modern improvements would be in order:

• The belt drive should be covered with a guard to prevent potential hazards.
• For an emergency power outage, a special button is installed in a visible place (at a close proximity).
• Instead of a grille, a protective screen made of transparent polymer is used.
• The incandescent lamp is replaced with an economical, mechanically resistant LED lamp.
• Automatic devices (sensors, fuses) are installed in the electric motor power supply circuit, which prevent overheating and other emergency situations.
• The frame is mounted on damping pads, reducing noise and vibration levels.
• The drive chuck is replaced with a more convenient three-jaw version, which automatically centers the workpiece during the fixation process.
• Fastening in the chuck grinding wheel expands processing capabilities.

Safety precautions when working with a homemade lathe and proper care

After assembly, you must ensure that there are no faults before connecting it to the network. Check the free rotation of the spindle, the absence of delays in the operation of the drive mechanisms and extraneous noise. Alignment is carefully controlled. It is necessary that the power supply parameters meet the needs of the power unit in the mode of highest power consumption when turned on.

Before starting work, make sure that protective screens and casings are available (in good condition). New tool installed with the electric motor stopped using all standard fasteners. Observe processing modes corresponding to the parameters of the cutters and workpiece.

After completion of work operations, waste is removed. Perform lubrication and other work required by the maintenance regulations in a timely manner.
