Homemade machines - how to make useful devices

Wood is easy to process. Using simple tools, you can create things of amazing beauty and functionality.

Separately, it is worth noting products that have the shape of rotation figures: tool handles, staircase balusters, kitchen utensils. To make them, an ax or chisel is not enough; you need a lathe.

Buying such a device is not a problem, but a good machine is expensive. It’s not difficult to acquire such a useful tool and save money, because you can make a wood lathe with your own hands.

Using homemade machines in the workshop

The work that is performed in the workshop affects the equipment of the room with special devices. Typically, equipment is placed if the free area is at least 3 m2.

Workshops are often set up in small rooms, outbuildings, and garages. The best place is a separate building. In this case, the noise from the work being performed will not disturb other residents of the house.

Universal workshops are often set up to perform various jobs. If a person is engaged in the production of any products, then specific homemade tools and devices are made. Often workshops are equipped with machines for carpentry and processing of metal blanks. Often, premises for the repair of wheeled vehicles are also set up.

Basically the workshop is equipped with:

• devices that allow you to prepare tools, facilitate labor and mechanize operations;
• homemade products for processing metal parts;
• workbenches.

It is also necessary to install shelves in the room where various tools will be stored. At the same time, they ensure unhindered access to them and compliance with fire safety rules.

Making a grinder from a grinder

Many may say that the “grinder” is the same as an angle grinder, but there are some subtleties hidden here. It should be borne in mind that the angle grinder has very high speeds and often quite a decent weight. To polish a surface with a grinder, you need to have considerable experience in this matter and use special polishing discs and circles. The grinder has much lower engine speed and weight. To operate a factory grinding machine, no specific experience or skill is required. You can independently make a good grinder from an angle grinder, which is not inferior in its parameters to a factory machine, only by modifying its electrical circuit, by installing the regulator at lower speeds and by using special grinding attachments.

Workbench for a carpenter

This type of equipment is a table. It is distinguished by its high strength and the presence of 2 vices on the tabletop. The table is also equipped with clamps that clamp the workpieces during planing. In addition, the workbench may still have places where other homemade devices, such as a router, will be attached.

A special table must have a comfortable height. She matches the height of the master. The minimum length of the workbench is 1000 mm. Often it is equal to 1700 mm or even 2000 mm. The standard width is 800 mm.

A workbench table is created as follows:

• The table surface is created - this is a shield, which is made from oak, beech or hornbeam boards with a minimum thickness of 55 mm. They are tightly fitted to each other. The boards used are impregnated with drying oil before joining. To create a rigid structure, a 50 mm block is used. It is fixed around the perimeter of the working surface.
• The supporting elements of the workbench are made. To do this, use linden or pine timber. Its size is 120*120 mm or 150*150 mm, and its length is approximately 1200 mm. The supports are connected by jumpers in the horizontal plane. To do this, take boards that are fixed at a distance of 300 mm from the floor.
• Make homemade devices to accommodate the tool. These are shelves located under the countertop. When they are open, they are often replaced with bedside tables.
• Attach a vice.

If a stationary workbench is created, its supporting elements are fixed to the floor. Depending on the specifics of the work being performed, mobile and collapsible tables are also manufactured.

Carpenter's workbench vice

This homemade tool is made using a screw rod. Its thread length must be at least 160 mm. In this case, the diameter of the rod itself must be 20 mm. For the vice you will also need wooden blocks and metal pins. The manufacturing sequence is as follows:

1. Prepare a block of 200*300 mm. Its minimum thickness should be 50 mm. This will be one of the sponges. A hole for a screw is drilled in the center of the workpiece. On the sides of it, two more holes are made for the studs.
2. A second movable jaw 200*180 mm is cut out and similar holes are drilled in it.
3. A threaded pin is inserted into the workpiece. A handle is installed at one end. To prevent the jaws from moving, pins with a cross section of 10 mm are passed through other holes.

Metal workbench for a mechanic

All useful homemade products and devices simplify the processing of workpieces. Such devices include a workbench for a mechanic. Its minimum dimensions are:

• length – 1800 mm;
• width – 700 mm;
• height – 900 mm.

The table is created in the following sequence:

• frame assembly;
• installation of 2 cabinets, covered with metal;
• securing a working surface consisting of a wooden base in the form of a shield, on which a sheet of metal of a suitable size is placed on top;
• assembly and installation of a rack at the back of the workbench to strengthen the entire structure and accommodate tools.

When assembling a bench, use:

• beams as racks - four corrugated pipes 40*60 mm with a wall thickness of at least 2 mm;
• three beams 50*40 mm to connect the racks and ensure longitudinal rigidity of the structure;
• corrugated pipe 40*30 mm with a wall of at least 1 mm in the amount of 9 pieces to create the frame of the cabinets;
• metal corner 50*50 mm for the manufacture of shelving racks, the height of which will be a maximum of 2000 mm;
• board 50 mm thick for the tabletop panel;
• a sheet of metal no thinner than 6 mm to cover the top surface of the workbench.

A simple way to make your own frame

The reliability of the bed is a key characteristic of the machine. Human safety and the quality of the product depend on the properties of the material and the quality of the connection of the parts of the frame.

Based on these requirements, the choice falls on metal profiles, chipboard, plywood or solid wood (preferably solid wood: oak, birch or the most common: pine).

If the choice is on a metal frame, then you need to choose a channel, an I-beam or a profile pipe that will carry the load-bearing functions of the machine. Here the choice depends solely on the availability of the material, its price and ease of installation. However, the metal frame is the simplest in design: you only need two I-beams, on which the engine, tailstock, tool rest and caliper are then mounted.

If the choice is wood or chipboard, then based on a preliminary sketch-drawing with the existing dimensions of the engine and all other elements, the design of the frame is formed. As a rule, it consists of a table top, which acts as a base, a stand for the tailstock and a box on which the motor and headstock axle are mounted.

In addition, two parallel slats are run between the headstock racks, on which a movable support board is attached. A gap of 5 cm is maintained between the slats. Afterwards, it is necessary to weld the frame with a welding machine - this will give additional strength to the structure.

If the machine is supposed to be a tabletop machine, then there is no need for legs, but when processing heavy and massive elements, the bed should be independent and its stability should not raise questions. In this case, it is necessary to provide legs. They are made from rolled steel, for example, angle or timber.

The dimensions of the machine primarily depend on the goals pursued by the master. Most operations at home are performed with products up to 80 cm in length, so most often the length dimensions of the machine are 80 cm. If the frame is made of metal, then two blanks of equal length are cut with a grinder.

Wood lathe for lathe

There are various homemade machines and machines for the workshop. They all make the job easier. These include a lathe. Its structural elements are:

• Durable frame made of metal angle or pipe. Sometimes it is created from wooden blocks. The bed is fixed to the floor, and its lower part is weighted.
• A support, which is a supporting element for the cutters. This part of the machine must provide reliable fixation and allow the workpiece to move to the side. For this purpose, the design provides a screw rod.
• The clamping spindle, also called the headstock. The head of a powerful electric drill is often used as it.

• Tailstock used for longitudinal movement of the workpiece. It is recommended to use the factory spindle, which has four cams.
• Electric drive providing rotation of 1500 rpm. Its power should be from 250 to 400 W. Often a washing machine motor is used as an electric motor. The design also includes a belt drive. This is a transmission, for the operation of which it is necessary to install pulleys on the shafts.

Cutters for the machine

It is recommended to equip homemade devices with factory cutters. After all, they are sharpened with high quality using special equipment. As a last resort, for production use:

• old files without significant defects;
• steel square reinforcement is the optimal material for making cutters;
• square or rectangular spring from the car.

Subsequently, the existing workpieces are sharpened. Creates a semi-circular cutting edge for roughing wood parts. Finish turning work is carried out with a cutter that has a straight blade.

After sharpening, the cutting elements are hardened. During this process, the cutters are first heated and then placed in machine oil.

Direct drive or belt drive

There are several ways to transfer rotation to the workpiece. The simplest is direct drive. In this case, the workpiece is attached directly to the motor shaft. A distinctive feature of this design is its simplicity. With all this, direct drive has a number of significant disadvantages.

First of all, a direct drive machine does not allow you to adjust the rotation speed, which is critical when working with hard material. It is also worth considering the load on the electric motor, especially when working with large workpieces. No matter how well it is centered, it cannot do without vibration. Motor bearings are not designed to withstand longitudinal loads and will often fail.

To protect the engine from damage and provide the ability to adjust the speed of rotation of the workpiece, it is worth considering a belt drive. In this case, the engine is located away from the axis of rotation of the workpiece, and torque is transmitted through pulleys. Using pulley blocks of different diameters, it is easy to change the speed within a fairly wide range.

It is advisable to equip a machine for your home with pulleys with three or more grooves, which will allow you to process wood of any species with equal success, and, if necessary, work with soft alloys.

Stationary circulation saw

The stationary circular saw is placed on a sturdy table. Its working surface is usually made of metal sheet. It is reinforced with stiffening ribs. For their manufacture, a steel angle is used.

On the working surface there are usually:

• stops;
• guides;
• elements for adjustment;
• cutting disc.

On a note! The circular saw is powered by an electric motor. Its power should be approximately 800 W, and its rotation should be 1700 rpm. The electric motor of the angle grinder corresponds to these characteristics.

Before making a device for sawing wooden parts, prepare a working angle grinder with the necessary characteristics. Further actions are performed in the following order:

1. Assembling the frame.
2. Prepare a worktop in which a slot is made for the cutting disc.
3. Two wooden blocks are fastened in parallel. They will be used as stops.
4. Set the scale necessary to control the cutting of wooden parts.
5. Clamps are installed so that workpieces and guides can be fixed.
6. The grinder is secured by first installing the disk into the previously created slot in the table top. The power tool is fixed from below the working surface.

Safety precautions when working on a sanding grinder

Like any other work on any other machines, grinding on a homemade belt sanding machine is subject to fairly strict safety rules that must be strictly adhered to.

The principle of operation of the grinder.

These rules are as follows:

• It is strictly forbidden to touch anything that moves with your hands while the machine and working surface are operating.
• Wear safety glasses while working to protect against hot abrasive particles.
• Carefully check that the connections and fastenings of all moving parts of the grinder are tight.
• Monitor the condition of the braiding of electrical wires.
• A protective casing is a must, even though it slightly narrows the viewing angle.

Drilling machine

Interesting homemade products and devices often help craftsmen out when making various products in the workshop. One such device is a drilling machine. Its main parts include:

• electric drill;
• base made of metal parts with the ability to secure the workpiece;
• a stand for fixing an electric drill, which is created using chipboard with a thickness of 20 to 25 mm or an old photographic enlarger;
• a unit that supplies the drilling tool.

The drill press stand must have guide rails. They are necessary for the electric drill to move strictly in a vertical direction. There are different options for feeding an electric tool, but the most common design is a lever with a spring. It is manually controlled by simply pressing. The design of the machine also includes stops. They are needed to adjust the depth of the hole created in the part.

How to make a handicraft at home?

The support for guiding the cutter along the shaft of the workpiece is a tool rest. It is best to make it from a steel pipe or angle iron, because wooden supports wear out quickly and are not able to withstand as heavy loads as a metal part of the same size.

You can make it by welding two pipes in a T-shape, or you can do it even simpler and fix a piece of board with a wooden boss on the frame, but the accuracy and wear resistance of such a design is not durable. The main thing in arranging a tool rest is that the upper edge of the pipe or angle must correspond to the axis of rotation of the workpiece: in this case, the risk of breaking the chisel is minimal.

Important!

When working on a lathe, only the lower part of the workpiece can be processed! Failure to do so may cause the incisor to become jammed or fractured, which can result in serious injury. When operating a woodworking machine, be sure to wear safety glasses to reduce the risk of injury.

CNC router

There are homemade machines and devices of complex design. Such devices include a CNC router. It is made for processing metal and wooden parts.

Work with a CNC router is carried out to a higher quality. This machine has advanced capabilities. When creating it, an LPT port is used, and numerical control is also provided. The copying unit is created from printer carriages with a matrix of needles.

The milling device is assembled as follows:

1. The tabletop is made using a plywood sheet. Instead, chipboard with a thickness of at least 15 mm is used.
2. A cutout is created to accommodate the cutter.
3. The milling unit is installed.
4. The electric drive is located.
5. The transmission is secured.
6. The spindle is mounted.
7. The stops are fixed.

A CNC milling machine for processing metal workpieces is made with a more durable frame. The device is created in the following sequence:

1. The column and frame are mounted when using a channel. From them a structure in the shape of the letter “P” is created. In it, the bridge between two supporting elements is formed by a part that is the base of the milling unit.
2. Guides are made from angle iron. They are fixed with bolts on the column.
3. Guide consoles are created from a pipe with a rectangular cross-section. To move them to a height of maximum 150 mm, the design provides a car jack.
4. A threaded pin is inserted into the console.
5. A working surface is created.
6. A vice, fixing elements and guides are installed.
7. The rotating unit is mounted. In this case, they strictly ensure that the shaft is in a vertical plane.

Thus, part of the structure of the described machine can be used for the manufacture and subsequent assembly of three more additional devices. If necessary, having all the components, you can assemble the devices you need at the moment at your own discretion.

Thicknesser

Crafts for the workshop are often created to perform woodworking. The material always has to be planed. It is to solve this problem that a surface planer is made. The machine consists of the following parts:

• The frame consists of two frame structures, which are welded from 40*40 mm corners. The frames are fastened with studs.
• Tabletop made of metal or lumber, pre-impregnated with drying oil. The working surface is bolted to the frame.

• A broach consisting of rubber rollers. They are taken from a broken washing machine. The rollers are provided with smooth rotation by sliding them onto bearings.
• A casing that protects rotating parts. It is made of sheet metal about 5 mm thick and fixed to a frame made of corners measuring 20*20 mm.
• Electric motor with a power of 6 kW, which can rotate at a speed of at least 3000 rpm.

Clamps are used to secure the thickness planer. The device is fixed on the working surface. Do not forget about the required gap, when setting it, take into account the thickness of the workpiece.

Headstock and tailstock

The workpiece being processed is clamped between two devices called the headstock and tailstock. Rotation from the engine is transmitted to the front one, which is why it is a more complex unit.

Structurally, the headstock of a homemade lathe is a metal U-shaped structure, between the side faces of which a shaft and one or more pulleys are mounted on bearings. The body of this unit can be made of thick steel; bolts of sufficient length are suitable for assembling it into a single whole.

An important part of the headstock, as well as the machine as a whole, is the shaft, a spindle with three or four pins designed to fix the workpiece. This shaft is passed through the bearing of one of the cheeks of the U-shaped housing, then pulleys are mounted on it. To fasten them, a key or a means for fixing cylindrical parts is used, the second cheek is put on last, and the structure is securely tightened with bolts.

The tailstock's job is to support the long workpiece while allowing it to rotate freely. You can buy a ready-made part from a factory machine, or you can use a powerful electric drill chuck mounted on a square of suitable length. A shaft with a pointed end is clamped into the cartridge itself.

The headstock and tailstock are installed on the bed. It is important to understand that the axes of rotation of both shafts must completely coincide. Otherwise, breakage of the workpiece, failure of the machine, and possibly injury to the turner are likely.

Wood sanding machine

The design of such a machine has a cylinder on which sandpaper is placed. This unit rotates while processing the part. The assembly of a homemade machine is often performed for grinding cylindrical workpieces. A device is also made to create a flat surface of the workpiece.

When fixing the sanding paper, follow these rules:

• the width of the abrasive cloth should be approximately 250 mm;
• the sanding belt is connected without a gap exclusively end-to-end;
• The sandpaper is attached using a high-quality adhesive;
• at the edges of the shaft for the abrasive cloth there must be a side, the protrusion of which is from 2.5 to 4 mm;
• a rubber backing should be placed under the tape.

The shaft of the device is rotated by an electric motor. These two parts of the machine are connected by a belt drive. The design of the frame itself can have different designs. The option is chosen depending on the size of the workpieces being processed.

Design

There is nothing particularly complicated in the design of a belt grinder. The device consists of a motor, drive and guide rollers. A sanding or roughing belt of the required grain size is passed through them.

When the engine is turned on, the drive roller mounted on its shaft begins to rotate, and through the tensioned working belt, the rotation is transmitted to the guide rollers. By pressing the part to be processed in the working area against the belt, the operator performs the required operation, changing the position of the workpiece relative to the surface of the belt if necessary.

By adjusting the distance between the guide rollers, it is possible to process surfaces with defects of different depths. During prolonged use, the sanding belt may not stretch much. To compensate for possible slack, a tension mechanism is provided in the design on one of the rollers. Typically, such a function is assigned to a roller located at the same distance between the leader and the slave.

The grinding machine is supplied with a support table, which also serves as a surface for fixing the workpiece. As a rule, such a table should be able to rotate 90 degrees about one axis. In this case, it is possible to process two perpendicularly located planes without reinstalling the part on the support table.

Of course, a grinder control panel is required! For safety reasons, it is recommended to mount it on the machine frame in close proximity to the operator’s working area. Portable machines are equipped with a stand made of durable steel with mounting holes on the base, allowing you to fix the unit on a wooden surface.

If you look at the design details, you can immediately notice some visual instability of the assembled grinding device. The overhang of the side dimensions of the installed rollers significantly exceeds the supporting surface on the base. In addition, the absence of a support table makes it difficult to effectively process relatively large surfaces, and holding the part in a canopy is inconvenient and quite dangerous.

An increased length of the working belt leads to additional losses due to friction. It is necessary to use a higher power power unit in the drive, and this increases energy costs. The tension unit is simple and functional. Adjusting the tension is a matter of seconds. The machine comes with replaceable sanding attachments, which can be used for sanding even on internal surfaces. Despite this, the cost is 100 thousand rubles. makes me think.

Briefly about the main thing

Typically, craftsmen assemble machines for their workshops if the area of ​​the room is at least 3 m2. Universal devices are manufactured or to perform a specific type of work. In addition to shelves and racks, in the workshop you can often find a workbench for carpentry work made of boards and bars, which is equipped with a vice.

Craftsmen also make a metal workbench from corrugated steel pipes, angles, and sheet metal. They also assemble a lathe on a metal frame, with a clamping spindle in the form of a drill head and an electric drive. Also popular in the workshop are a stationary circular saw based on a grinder, a drilling machine made from an electric drill, a surface planer made from an electric planer, and a CNC router.
