How to make a universal machine from a household drill. Homemade drilling machine from a drill

For household chores, the functions of a drill may be sufficient, but more precise equipment may be needed to improve the quality and productivity of work. One of the most popular varieties is a do-it-yourself mini-drilling machine.

Drilling machine components

The first stage before production is to study the design. To do this, it is recommended to take a drawing of a standard machine and familiarize yourself with its components. Important to understand general principle functioning and in the future to determine the optimal scheme of a self-made design.

Main functional purpose is to form holes various types. Depending on the configuration of the equipment, there may be drawings of vertical drilling, jig boring, radial drilling, filler models. The difference between them lies in the possibility of changing the direction of action cutting tool. For domestic needs, a vertical drilling mini-machine is most often made by hand.

Structurally, it should consist of the following elements:

• bed. The supporting part on which the vertical rack is attached;
• rack. Designed for installation of electrical equipment;
• electrical components. They include an electric motor and a mechanism for transmitting torque to the spindle.

Most often, for the production of a home-made drilling machine, do-it-yourself use standard drawings in which the electric motor is replaced by an electric drill. This allows you to reduce the complexity of the work. However, such designs are designed only for small loads.

Before self-production of a mini-machine, you should decide on the type of work performed on wood and metal. This will depend on the characteristics of the equipment.

Homemade drilling machine from a drill

The most popular model currently is a mini drill machine. To make it at home, you only need to make a bed and a rack.

In some cases, it can be done without the use of homemade elements. To do this, you need a factory bed and a drill. It is not necessary to draw up drawings for this, however, such a design has one significant drawback - a large backlash. During the execution of work, the cutting tool is shifted relative to the drilling site. This must be taken into account before drilling machine.

It is best to use standard drawings for the production of a homemade drilling machine with your own hands. The production technology directly depends on the selected components. But experts recommend adhering to the following rules when choosing the source material, as well as its processing:

• for smooth raising and lowering, you can use the steering rack. An alternative option is to adapt a mechanical jack;
• support table and stand are made of steel channels and corners. It is important to ensure sufficient mass of the lower part of the structure for maximum stability of the machine during its operation;
• separate control unit. Turning the drill on and off will be inconvenient. Therefore, it is recommended to install a standard switch on the side of the mini drill press.

During the execution of work, it is necessary to ensure the maximum accuracy of pairing of structural elements. The angle between the support post and the table should be 90 degrees. For filler models, the minimum thickness of the metal base plate must be at least 3 mm.

To increase the functionality of the equipment, you can do. It provides the ability to move the workpiece relative to the cutting tool. This will achieve maximum processing accuracy.

Homemade high power machine

If it has unsatisfactory parameters, you can consider other drawings of a similar design. Their difference from the above model is the use of an electric motor as the main power plant.

Making such a design at home will be problematic, as it will take a lot of time and effort. The motor can be made from washing machine. The cartridge for attaching the cutting tool is not made by hand, it is taken from an old machine. Additionally, pulleys will be required to transmit torque.

In general, the technology remains the same. It is important to correctly calculate the optimal power of the electric motor, as well as provide for the possibility of changing the number of its revolutions. To do this, you can put a reducer.

As additional equipment, you can make a vise at home. They will fix the parts to perform precise processing.

The video shows the exact diagram and drawings for the production of a mini-drilling machine with your own hands:

Examples of drawings and finished machines

The most common drilling machine can be considered one that is made from an ordinary or electric drill. In such a machine, a drill can be placed both stationary and made removable. In the first case, the power button can be transferred to the drilling machine for greater convenience, in the second, the drill can be removed and used as a separate tool.

Components for a homemade drilling machine:

• Drill;
• Base;
• Rack;
• Drill mount;
• feed mechanism.

The base (frame) for a homemade drilling machine can be made of hard wood, chipboard or furniture board, but it is still better to use a channel, metal plate or brand. To ensure the stability of the structure and obtain a good result, the bed must be made massive so that it can compensate for the vibration from drilling. The size for wooden satin is 600x600x30 mm, for metal - 500x500x15 mm. Mounting holes must be present on the base of the machine so that it can be fixed on a workbench.

The stand for the drilling machine can be made from timber, round or square steel pipe. You can also use an old frame of a photographic enlarger, an old school microscope or other device of a similar configuration with a large mass and high strength.

The drill is attached with clamps or brackets. It is better to use a bracket with a center hole, this will allow you to achieve better results when drilling.

The device of the feed mechanism of the drill on the machine.

Through this mechanism the drill can move vertically along the rack, it can be:

• spring;
• Hinged;
• Similar to a screw jack.

Depending on the chosen mechanism, you will need to make a rack.

The photo diagrams and drawings show the main types of designs of home-made drilling machines that use a drill.

Step by step instructions for making a steel rack.

The steering rack from the car is a fairly massive device, so the bed under it must be massive and attached to the workbench. All connections on such a machine are made by welding.

The thickness of the base should be about 5 mm, it can be welded from channels. The drain on which the steering rack is attached should be 7-8 cm higher. It is attached through the eyelets of the steering column.

Since such a home-made machine becomes massive, it is better to take out the control unit separately from the drill.

The assembly procedure for such a homemade machine:

• Preparation of details;
• Installing the rack on the frame;
• Assembly of the movement device;
• Installing the device on the rack;
• Drill installation.

All connections must be securely fastened, preferably by welding. If guides are used, then you need to make sure that there is no lateral play. For greater convenience, such a machine can be equipped with a vice for fixing the workpiece for drilling.

In stores, you can also find ready-made stands for a drill. When buying, pay attention to the dimensions of its frame and weight. Often inexpensive designs are only suitable for drilling thin plywood.

Homemade drilling machine based on an asynchronous motor.

Replace drill in homemade machine can be an asynchronous motor, for example from the old washing machine. The manufacturing scheme for such a machine is complex, so it is better if it is done by a specialist with experience in turning and milling, assembling electrical circuits.

How to make a drilling machine for printed circuit boards with your own hands.

To manufacture a drilling machine for printing circuit boards, a drive of a low-power device is required. As a lever, you can use a mechanism from a photo cutter, a soldering iron. Illumination of the drilling site can be done using led flashlight. In general, this machine is rich in flight of creative thoughts.

A drilling machine is a unique device that is essential for a home workshop. It allows you not to seek help from specialized workshops, but simply take and carry out work on the groove yourself.

Thanks to this, a person saves a huge amount of money on the services of turning specialists.

You can make such a device from improvised materials. There is nothing complicated in the process.

For the production of a home drilling machine, you only need an electric drill or a steering rack.

The purchase of industrial units will cost a pretty penny, so it is more expedient to make your own model using drawings with dimensions, which are full on the Internet.

Before proceeding with the creation of the unit itself, a layout should be completed. This is a responsible step that requires a careful approach and drawing up a drawing. It is necessary to carefully measure and display on paper the dimensions of the future machine. If this is not done, something will definitely go wrong in the work.

It is easy to make a mistake, and having a drawing will not allow you to make mistakes. People who neglect this step in creating a drilling machine with their own hands overpay in the process of its manufacture. Things to keep in mind while working:

Drawings with dimensions.

• Length, width and height of equipment;
• The thickness of the aggregates;
• Technical characteristics of electrical equipment;
• Data of the engine that will serve as a drive for your machine;
• Power consumption energy;
• grounding;
• The number of consumables.

The drawing will allow you not only to visually understand how to assemble the equipment, but also how it will look exactly. The project will provide an opportunity to more clearly determine the amount of production costs.

To assemble such equipment in your workshop, you do not need to have specialized items or electrical equipment. All you need is 4 basic ingredients. First of all, a frame should be selected for the filler machine. It will serve as a powerful foundation for a future turning device.

After that, we determine the mechanism of rotation. For him, it is better to choose an electric drill.

Tip: Take a drill that is not too old, but not too new either. The main thing is that it be in working condition, otherwise the equipment can quickly fail.

The third step is to choose a device for feeding revolutions

on the working part of the drill, as well as determine the stand, vertical type. The drill itself is lightweight, so you don’t need to look for heavy-duty materials for the stand. An ordinary board or chipboard will do.

Tip: An asynchronous motor from an old washing machine is ideal as a drive.

The bed, on the contrary, is selected from those materials that will be stronger. It should hold everything on itself, and also dampen the rattling of the drill itself. So that vibrations do not affect the equipment and the accuracy of work, it is best to select strong metals. Very good, an old photo enlarger stand will do as a holder. True, to create a drilling machine with your own hands, you will need to modify it.

Important! The accuracy of the drilled hole will depend on the quality of the connection between the rack and the frame of the unit.

Also, the creator of the home loom will need to use several steel strips to cut out two guide bars. They will help to carry out the movement of the block on which the drill is located. You can use screws to secure them. We take and fasten everything to the rack.

Clamps will help to increase the strength of the fixation of the drill. It is best to use steel, they can withstand a higher load. To dampen vibrations even more, it is best to place a rubber gasket between the block of the machine and the drill. It will help you eliminate the rattling of home equipment during operation.

At the heart of the movement of the machine is the lever. It allows you to safely move the block with an electric drill in a vertical position. A spring will be installed there, which will allow maintaining the drilling apparatus in the desired tension.

Choosing and installing a steering rack for a drilling machine

To your home equipment worked as conveniently as possible, it is best to use an upgraded steering rack during its creation.

If you're going to buy it brand new from the factory, prepare a tidy sum

because it's not cheap at all. A more profitable solution is to choose a used part, best of all from the VAZ 2108.

Tip: As soon as you bought such a spare part, you should carefully inspect it, carry out preventive maintenance and repair if necessary. Thus, it will turn out to give it a smoother ride while working with a drilling machine.

Now let's start making a bed for your future drilling equipment

1. To make the case, you will need to use a drill along with a column. All this should be installed on a table that will serve as a platform for the future drilling machine. The dimensions of the table should be around 20x30 cm.
2. A special structure that will hold your electric drill is installed on the steering part of the unit. Bolts are used to tighten it.
3. To build the rack itself, you must first select a U-shaped steel profile with dimensions of 30x60x30. Then you need to weld it to a metal sheet with a thickness of 2 mm. In theory, the stand itself must be 6-7 cm higher than the length of the column itself.
4. As a rod stroke, it is best for the machine operator to use the VAZ 2108 steering rack, which was mentioned earlier, when creating equipment.
5. To further increase the rigidity of the entire structure during installation, additional ribs should be mounted.

To ensure that the operator does not have problems starting or shutting down the equipment during operation, consideration should be given to practical system start and stop the engine of the drilling machine.

In everyday life, not a very large machine may come in handy, but drilling equipment for working with micro printed circuit boards, as in the photo.

To make it, the creator will need:

• Micromotor or engine running at high speed.
• Special collet for clamping small drills.
• Several wooden blocks.
• Metal profile U-shaped.
• Retaining ring, which will help to more reliably fix the engine.
• A mobile platform for a machine tool, which is created by hand from all kinds of materials found in everyday life.

Important! So that the machine does not disappoint you in the end and works clearly and accurately, you should Special attention turn to lower the drill. It should be perpendicular to the board.

In the event that the motor is skewed under some circumstances, the user risks incapacitating the drills. During the production of home drilling equipment, you need to carefully monitor the quality of fixing the motor. If it was installed unreliably, when the engine is running at high speeds, it will simply be pulled out of the frame. This is fraught with damage to your property and the risk of harm to health.

How to make a coordinate table

In a home drilling machine, the role of the coordinate table will be carried out by the feed mechanism. And the same table, but for milling equipment, has a slightly different design. Therefore, it should be considered more carefully.

This equipment is a special manipulator, which consists of the number of axes required by the user. It is needed to move specialized technological heads of drilling equipment in several directions and planes at once.

Important! To make a milling table at home, one cannot do without the use of several linear-type modules. They must be made of aluminum profile.

To transfer motion when creating milling table a special toothed rack should be used, as well as a reinforced belt. Instead, a ball screw element will do.

To adjust the control of the coordinate table, the creator will need to use the CNC or controllers. Thanks to their installation, the user of the equipment has the opportunity to manage the technical tasks assigned to the machine.

Important! When creating a milling table for a drilling machine, be sure to make a drawing before you get started. This will allow you to clearly understand the algorithm of actions and save yourself from unnecessary mistakes.

In this case, the calculation is carried out taking into account specifications the drilling unit itself. The design itself can be both lightweight and with increased strength. And also 2 or 3 coordinates can be used there. First of all, before you create a machine, you should understand its main role in your home workshop. And start from this in the design process and further production.

When everything is ready, you need to make a vice, otherwise you will not be able to fix the part at home, it is strictly forbidden to hold it in your hands. Purchasing an old Soviet vise made of steel or cast iron can be expensive. Chinese-made models, not everyone will like them, to the extent of their fragility. Therefore, one of the economical options would be to make them yourself.

You will need:

• A screw with a thread of 2 cm and a length of 15 cm. There must be a slot in the head of the fastener.
• A special screw with a ring that is used for tightening.
• Hairpins.

You should make a motionless sponge. How to make this element? To create, use a pine tree. It is affordable and quite durable. The board should be grafted to the countertop.

To make the mobile part of the vise, you need a board with dimensions of 2 cm thick and 1.8 cm wide. The length of the movable jaws for clamps must be from 50 cm.

All that needs to be done is to cut holes with a diameter of 2.1 cm. In the studs, this diameter will be 1 cm. Then the creator simply inserts the studs together with the screws into the finished holes, after which he baits the nuts and tightens them with bolts.

And this completes the production of home vices.

When you have created your home drilling machine, you should definitely check it out.

Plug the engine into the outlet and if you did everything right, you have no short circuit, no uncharacteristic sounds for the unit to work - you can congratulate yourself on the successful completion of the project.

A homemade machine will allow you to perform simple drilling operations at home and save on the services of auto repair shops or turners.

Video how to make a drilling machine

The only thing is that in order for the equipment to work as long as possible, do not be shy and do not be lazy to inspect the working surfaces together with the engine for damage or wear of parts once every six months. Timely identification of the problem will allow you to save yourself from real trouble.

Drilling work is not particularly difficult and often does not require other equipment than a conventional drill. Therefore, in home workshops, a drilling machine may not be available. However, if you have a custom-made bench drill, you can breathe a sigh of relief, as part of your worries will resolve itself.

Purpose of the drilling machine

Sometimes there are situations when an electric or hand drill is not able to provide the desired parameters of the hole being drilled. Often in amateur radio practice it is necessary to make printed circuit boards where you need to drill a lot of holes that have a small diameter. Drilling holes with a diameter of 0.5-1 mm with a hand or electric drill or a large drilling machine is inconvenient, and the drill may break.

Buying industrial drilling machines is not always economically feasible, and then you can make a homemade drilling machine. Many people choose mini drilling machines, because, despite the apparent complexity of the design, they are actually very simple equipment and consist of four parts.

A self-made drilling machine is designed for drilling through and blind holes in solid material, for example, reaming, reaming, countersinking, cutting discs from sheet materials and cutting internal threads. Drilling and milling machines can perform milling, surface grinding, bevel milling and horizontal milling.

To perform the above operations, a countersink, drill, tap, reamer and other tools are used. Using special fixtures and additional tools, you can cut a hole with a large diameter, bore a hole and accurately lap the hole.

Types of drilling machines

Drilling machines are of the following types: single and multi-spindle semi-automatic, vertical drilling, jig boring, radial drilling, horizontal boring, horizontal boring, diamond boring. Models are designated by numbers and letters. The first digit indicates the group to which the machine is assigned, the second - the type of machine, the third and fourth - the dimensions of the machine or the dimensions of the workpiece being processed.

The letter that comes after the first digit means that a certain model of the drilling machine is upgraded. If the letter is located at the end, then it should be understood that, on the basis of the main model, a drilling machine different from it was made. It is possible to distinguish from all drilling machines such main varieties of universal machines: multi- and single-spindle, radial and horizontal drilling.

Depending on the area of ​​​​use, a distinction is made between special and universal drilling equipment. Specialized machines for mass production and large-scale industry have also found wide application, which are manufactured on the basis of universal machines by equipping them with multi-spindle thread-cutting and drilling heads and by automating the work cycle.

Drilling machine design

The drilling machine, like other technological machines, consists of such constituent parts: transmission mechanism, engine, controls and working body. The transmission mechanism is designed to transmit movement from the electric motor to the working body, which is considered to be a drill, which is mounted in a chuck mounted on a spindle - a rotating shaft.

Rotation to the spindle from the electric motor is transmitted by means of a belt drive. By turning the handle, the chuck and drills can be lowered or raised using rack and pinion.

On the front panel of the drilling machine there are buttons for switching off and on the electric motor. The device of the drilling machine is quite simple: the machine is turned on by pressing one of the extreme buttons, depending on the desired direction of rotation of the spindle, you can turn off the machine by pressing the middle red button.

A fixed vertical screw-column is attached to the base of the machine. By turning the handle, you can move the headstock up or down along the screw, the second handle serves to fix it in the required position. Control the depth of blind holes using the provided scale.

Depending on the workpiece material, different drilling speeds are required. To do this, it is customary to set a certain spindle speed by transferring to the pulleys various diameters belt drive belt. More than complex schemes drilling machines than were just discussed.

The principle of the machine

Before drilling with a homemade machine, you need to remove everything superfluous from the desktop. The workpiece with the marked centers of the holes must be fixed in a vise. Then insert a drill of the desired diameter into the chuck and fix it with a special key. To check the correctness of the work performed, the machine is turned on for a while.

If you have correctly installed the drill, when rotating, its tip will not describe a circle. If it is installed with a warp and its beating occurs, then the drilling machine must be turned off and the drill must be fixed according to the instructions of the drilling machine. Then turn the feed handle, lower the drill and set the vise with the workpiece in such a way that the core coincides with the tip of the drill.

Turn on the machine and drill a hole, press the feed handle smoothly, without much effort and jerks. When drilling a through hole, place the workpiece on wooden block so that the drill does not break and the machine table does not deteriorate.

When drilling deep hole take the drill out of the hole from time to time and cool it by dipping it in a bowl of coolant. It is recommended to reduce the pressure on the handle at the end of drilling. After drilling a hole, smoothly turn the feed wheel, raise the spindle to its highest position and turn off the machine.

Drilling machine manufacturing

A drilling machine is easy to make with your own hands. In everyday life, it is beneficial to have fixtures and tools for carpentry and plumbing work on hand. After the obsolescence of many household appliances, many useful spare parts and electric motors remain in the arsenal of the owners, from which, if desired, you can make such useful equipment as a drilling machine.

Drilling machine from a drill

by the most simple solution for you there will be an assembly of a mini drilling machine with your own hands using a drill. The drill weighs a little, so the stand can be made from chipboard, boards or sheet metal. For comfortable work on such a home-made machine, it is necessary that it turns out to be quite massive to absorb the vibration of the drill and sufficiently stable.

It is important to get a right angle between the holder and the base. Usually, the drill is attached with two clamps (it is better to place a rubber gasket between the clamp and the drill) to the board, which moves along the guides that are fixed on this movable board and on another fixed board. The downward and upward movement of the movable board is controlled by a lever associated with it.

The downward movement of the lever can be limited by a bar supporting the lever in the lower position. A fixed board is attached to a horizontal pipe through a flange. A horizontal pipe through a square is attached to a vertical pipe, which is attached through a flange to the base of the machine (to a thick wide board) or to a workbench.

The height of the bar, which limits the lower position of the lever, is adjusted, which allows you to change the depth of drilling. Make 4 holes in the movable board, which are intended for clamps fixing the drill. On its side, which faces the fixed board, narrow rails are glued, which are lubricated with wax for better glide.

The drill, in addition to clamps, is fixed with two rods that support it from below. Since with such a fastening, the shape of the drill does not strictly ensure the vertical position of the drill, it is necessary to glue a lath to the board to compensate for this.

To ensure the free movement of the drill, the guides must be prepared strictly in the vertical direction. They can be a ledge metal profiles from aluminum, which are screwed with threaded screws to the boards along the entire length. Having assembled a solid and stable structure, it is necessary to fix the profile guides strictly perpendicular to the plane of the base and parallel to each other.

In the photo of self-made drilling machines, the places of attachment to the movable platform of the drill and the method of mounting the guide profiles are clearly visible. The guides must ensure high-quality pressing of the movable to the fixed board. The main condition for this is the absence of distortions and backlash.

When assembling the lever, remember that you cannot tighten the moving parts; it is customary to use a second nut to lock the nuts. The rail that leads to the movable board from the lever should be rounded at the end. After reducing the pressure forces to automatically raise the drill to the upper position, it is necessary to put the springs on compression or tension.

One end of the spring is attached to the horizontal pipe with a wire, and the other end is attached to the bottom of the movable board. When the spring is not flexible enough, and a fixed board interferes, then this is done through a rope.

Machine from a motor from a washing machine

The drawing of a drilling machine, which is assembled on the basis of a motor from a washing machine, differs from the one discussed above in the most complex mechanics and the type of electric drive. The asynchronous motor from the old washing machine is heavier and has more vibration. The shaking will be stronger the farther from the rack the engine is located.

Intense vibration provokes inaccurate drilling and breakage of the drill. There are two ways out - to make a powerful frame so that when the drill is lowered, the drive also lowers, or the motor is placed motionless closer to the holder stand, then only the working part of the drilling machine will walk.

The second method involves a more complex implementation. Here you need a pulley and a belt that allow you to adjust the speed of rotation. There are many solutions without a belt drive with a drive located against the wall. They are much easier to assemble, but the assembly, which will be discussed below, is characterized by an unconventional approach, and certain applied techniques may be useful.

Vibrations still remain, but they are so minimal that when drilling iron with a 0.7 mm drill, the drill remains intact. At home, high precision in the manufacture of such mechanisms can only be dreamed of, but it is still necessary to strive for maximum fitting of parts. The characteristics of the drilling machine and its performance will depend on this.

The moving part of the machine consists of an axial hexagon, a tube of a suitable size, a clamping ring and two bearings and a tube with an internal thread to secure the chuck. On the hexagon, part of the future transmission system, a pulley is subsequently put on. The tube must first be cut with a grinder along both ends, and make the cuts on top deep enough to ensure a secure grip with the hexagon.

The entrance must be made tight, driven in with a hammer. If donning occurs without much effort, then you need to pick up another tube. Then stuff the compression ring and bearings. The height adjustment system consists of a pipe with cuts and a gear. To make the cuts accurately, you need to roll out the plasticine and drive along it with a gear.

An imprint will appear, which is easy to measure and make the appropriate markup on the adjusting pipe. The length of this ladder should correspond to the maximum height to which the drill can be raised. Press the axle with hexagon and bearings into the slotted tube.

Such a design will go back and forth vertically in the stationary tube of the bed when the gear is scrolling. At the same time, the axis is rotated in a horizontal plane through a belt drive. The bed is made from metal corner with bolts. The whole structure is attached to the wall.

And finally, remember that the first option for assembling a drilling machine is preferred. The proposed second version of the assembly can be supplemented or improved. However, such a simplified solution deserves attention.

» From the master class presented by the author, you will learn how to independently make a drilling machine from a drill for your workshop. What craftsman doesn't dream of owning his own drill press? But you yourself know what the prices for factory machines are) So, to get your own. the author made it himself. In principle, there is nothing complicated in manufacturing for a technical person. First, a base is made of 3 mm sheet steel, 2 corners are welded onto the edges of the plate, and 4 legs from a steel bar along the edges, the main thing is that the length of the legs is the same so that there are no distortions. After that, a lifting column 500 mm long is welded onto the prepared base, along which the slider will be raised and lowered with a drill fixed to it through a bracket and a clamp. The lifting mechanism is also quite simple, 2 brackets are welded on the slider that hold the rotating shaft, and a cable is wound on the shaft itself in several turns and stretched from the bottom to the top of the lifting column.

Again, having made this machine with your own hands, you can save a lot of money, which will favorably affect the family budget)

Drilling Machine Assembly Step by Step Guide

And so, before proceeding with the assembly of the machine itself, it is necessary to consider the drawing, but unfortunately it shows a slightly different design, of a spring type, but the principle remains essentially the same.

Next, you need to prepare and cut the base from 3 mm metal. Corners and legs are welded along the edges, which can be adjusted, namely, the thread is first welded, and then the bolt is screwed in. The slider is made of 2 corners welded into a pipe, for a start, the corners are applied to a square-section professional pipe and pulled together with a clamp. Clings along the edges, and then scalds. Here's what happens in the end. A lifting column is made from a professional pipe, its height is 500 mm. Brackets with a rotating shaft are welded onto the body of the slider for installing the cable. AT drilled hole thread is cut.
3 handles are being prepared from fittings for the lifting mechanism.
There is such a head on the shaft, the handles themselves will be welded onto it. Here's what actually happens. It is strung on the column rod. A loop is made on the rope. The cable is stretched, several turns are made on the shaft of the lifting mechanism. Next, the cable should be pulled. After that, the author makes a bracket for attaching the drill. This design is welded onto the corner. For convenience, tightens with a clamp.
Installs a clamp for attaching a drill. Clamps the drill with a clamp. Checks the operation of the lifting mechanism. The knots must first be lubricated with grease. Further, for fixing the workpiece in a fixed position, such a vice was screwed on.
Paint done. Threads are cut on the handles of the lifting mechanism. The machine drills a hole in the wooden head. It is screwed onto the handle of the mechanism. Also on the side there is a stopper for fixing. Here is such a wonderful and budget machine turned out by the author. Everything is ingeniously simple and very reliable, Master Golden Hands!

Thank you very much for your attention!
