Homemade drilling machine at home. Do-it-yourself drilling machine Do-it-yourself desktop drilling machine drawings

On the farm, the home master should have a set of all tools, and therefore this is the unit that will help him further expand his functionality.

Many for drilling various holes in everyday life can be satisfied with a conventional drill, however, the possibilities and tasks of even the simplest drilling equipment are more global.

A desktop drilling machine, in addition to reaming, countersinking and reaming, can also mill (there is a milling unit), as well as grind various surfaces, and also perform a number of other tasks.

Such equipment is especially relevant for radio amateurs, who, with the help of it, can solve a number of their narrowly focused tasks.

Such a unit for a home workshop can be bought at any specialized store, but it costs a lot, and not every master will find extra money to purchase a professional drilling machine, which is shown in the photo below.

Meanwhile, if you wish, you can assemble a home-made drilling machine for drilling wood and metal with your own hands from an ordinary drill.

Of course, you will have to spend personal time on the manufacture of the machine, but the result is worth it.

Desktop homemade drilling machine in a mini version for wood and metal, with all necessary materials, everyone can do House master.

Drilling the most different holes in everyday life it is carried out, as a rule, with the help of a hand drill, which is in the home workshop of every skilled owner.

Meanwhile, even at home it is not always possible to achieve the desired result through the use of an ordinary drill.

In this case, the question arises of making a mini vertical-horizontal drilling machine for wood and metal with your own hands.

Such a versatile unit is simply necessary for those involved in radio electronics for drilling small holes. printed circuit boards which cannot be done with a hand drill.

In addition, a home-made drilling machine will not interfere and, if necessary, drill through and blind holes in various types materials.

With it, it is very easy to perform reaming and countersinking, as well as, if necessary, to cut the thread.

If you additionally install a milling unit on it, then the capabilities of the unit will expand even more.

The milling unit will make it possible to perform a variety of simple operations for vertical-horizontal milling of a variety of materials.

The filler mini drilling unit for drilling printed circuit boards can be made from the most ordinary drill, however, to solve more challenging tasks a more structurally complex device, the same milling unit, will be required.

Any professional drilling unit consists of several required elements, which include such as a drill, countersink, tap, as well as a reamer.

Do-it-yourself filler mini machine must also contain all these components.

If the drilling machine is assembled according to all the rules with his own hands, then the home master can easily, using a milling unit, in addition to drilling printed circuit boards, cut and bore a hole with the required diameter, grind it precisely, and also perform a number of other specific tasks.

Before proceeding with the assembly of the unit, it is recommended to carefully study existing types drilling machines and understand the basic principle of its operation.

The video posted above shows a homemade drilling unit in operation, which can also be used for drilling printed circuit boards.

Species and types

Currently on industrial enterprises and used in everyday life great amount various modifications of drilling equipment.

Many of them are intended for solving exclusively professional tasks, and for home use they just don't fit for a variety of reasons.

In the photo below, you can see an industrial drilling machine.

Today you can find spindle machines, semi-automatic machines, vertical drilling, as well as many other types of units.

For domestic use, a filler mini unit is suitable, capable of solving simple tasks.

For example, if the machine is needed mainly for drilling printed circuit boards, then it can be assembled from the most ordinary drill.

Like any other equipment, drilling industrial units have their own special designations and markings, which can be used to determine their type and main purpose.

The most popular devices that are most often encountered are spindle devices, as well as units for radial and horizontal drilling.

Very popular coordinate unit designed for boring workpieces.

All drilling equipment can be safely attributed to the universal type. For a home workshop, it will not be difficult to make a universal-type filler mini-unit with your own hands.

If desired, a home-made coordinate unit can be automated as much as possible and supplemented with various devices, which will only add to its overall functionality.

Depending on the functional purpose, each drilling machine, including the coordinate one, consists of a certain number of elements.

Any unit of this type, including self-made, without fail consists of a bed, a steering rack, as well as an engine. The photo below shows a homemade filler mini drilling unit.

Design features

Drilling machine belongs to the type industrial equipment designed to solve narrowly focused tasks.

It must necessarily include a transmission mechanism, control and working bodies, as well as a sufficiently powerful electric motor.

Each mechanism included in this equipment has its own purpose, which determines its functional tasks.

So, the transmission mechanism is intended mainly to transfer the necessary movement to the working bodies, directly from the installed engine.

In this case, the working body is a drill, which is attached to a chuck, which in turn is connected to a spindle and a rotating shaft.

In the machine of this type, the rotation from the engine to the working bodies is transmitted by means of a belt drive. In order for the drill to be in a given position, a rack and pinion gear is used, associated with a special handle.

It is imperative that such a machine, even if it is assembled from a drill, must have buttons in an accessible place that are responsible for turning it on and off.

Machines of this type have a fairly simple device, moreover, they can perform a huge number of very different functions and solve many narrowly focused tasks.

Assembling such a machine with your own hands, for more high precision performing work directly on its moving part, it is recommended to place a special scale.

It will help control the depth of blind holes. It is also best to make such a machine on which it will be possible to change the rotation speed of the cartridge, depending on the tasks performed.

The desktop should be made exclusively from a solid metal plate, rigidly fixed to the base.

The video below shows a homemade drilling unit, with which you can drill printed circuit boards and more.

Principle of operation

A drilling machine assembled according to all the rules will be able to successfully drill holes of various diameters, including micro ones, with great accuracy, which is especially important for printed circuit boards.

Despite the apparent simplicity, you need to work on it in compliance with generally accepted rules.

So, just before you start work, you need to check the availability of power in the network, the integrity of all equipment, and also clear the desktop of everything superfluous.

There must be a vise on the table itself, with which it will be possible to conveniently fix the workpiece.

Before starting work on the part, it is necessary to mark the future hole in accordance with the drawing, then place it in a vise on the table and firmly clamp it.

Next, a drill is fixed in the chuck and a test run is made. Homemade vise for the drilling machine, which are used during work, must have certain dimensions, including in order to work with micro holes.

During the test start of the machine, it is necessary to check the rotation of the drill and make sure that it rotates without describing the circle.

This is especially true when drilling micro holes. At the time of drilling, the handle should be actuated with smooth movements, while the drill must be periodically cooled.

Drilling micro holes should be done with extreme precision, for which use coordinate indicators.

Upon completion of the work, the drilling machine should be turned off, open the vise and remove the finished workpiece. The video above shows how the machine works.

How to assemble?

The easiest option to assemble a filler drilling machine without a steering rack is to use an ordinary drill.

In this case, it is necessary to make the table massive in order to minimize the vibration of the machine during operation. A stand for a drill can be made from both chipboard and metal corners.

First you need to connect the stand and the table to each other at a right angle, while the drill should be fixed with clamps. A driving mechanism should also be provided.

A vise must be attached directly to the table, in addition, the on and off button must be in a visible place. In the video below you can see the manufacture of a machine from a drill without a steering rack.

You can assemble a more complex and functional machine with a steering rack for drilling from an engine from washing machine. This device will allow, among other things, to drill micro holes with great accuracy.

In this case, the desktop should be even more massive, since the vibration during operation will be quite strong.

Particular attention should be paid to the moving part of the unit, and for these purposes it is better to use ready-made drawings. It is recommended to connect the engine with the cartridge using a belt drive.

If all actions are performed correctly, then such a machine will be able to drill even micro holes with great accuracy.

The video below shows a homemade machine powered by an engine. washing machine which will be very useful in your workshop.

It is not necessary to spend money on a bench drill, because it is not so difficult to make it yourself. To do this, you will need to purchase, manufacture or use used parts. We will walk you through the creation of several designs, and you will be able to choose your own model for assembly.

Almost every owner who builds or renovates his house or apartment, repairs household and garden equipment, and various crafts made of metal and wood has a drill. But for some operations, a drill is not enough: you need special accuracy, you need to drill a hole at a right angle in a thick board, or you just want to make your work easier. This will require a machine that can be made on the basis of various drives, machine parts or household appliances, other improvised material.

The type of drive is a fundamental difference in the designs of home-made drilling machines. Some of them are made using a drill, mostly electric, others - using engines, most often from unnecessary household appliances.

Desktop drilling machine from a drill

The most common design can be considered a machine made from a manual or electric drill, which can be made removable, so that it can be used outside the machine, and stationary. In the latter case, the switching device can be transferred to the frame for greater convenience.

Main elements of the machine

The main elements of the machine are:

• drill;
• base;
• rack;
• drill mount;
• feed mechanism.

The base or bed can be made from a solid hardwood saw cut, furniture board or chipboard. Some prefer a metal plate, channel or brand as a base. The bed must be massive in order to provide stability to the structure and compensate for vibrations during drilling in order to obtain neat and accurate holes. The size of the frame made of wood is at least 600x600x30 mm, from steel sheet - 500x500x15 mm. For greater stability, the base can be made with lugs or bolt holes and fastened to a workbench.

The rack can be made of a bar, round or square in section of a steel pipe. Some craftsmen use the frame of an old photographic enlarger, a substandard school microscope, and other parts that have a suitable configuration, strength and weight as a base and stand.

The drill is fastened with clamps or brackets with a hole in the center. The bracket is more reliable and gives greater accuracy when drilling.

Design features of the drill feed mechanism

The feed mechanism is needed to move the drill vertically along the rack and can be:

• spring;
• articulated;
• screw jack design.

Depending on the type of mechanism adopted, the type and arrangement of the rack will also differ.

The drawings and photos show the main designs of bench drilling machines that can be made from electric and hand drills.

Machine based on the steering rack of a car

The steering rack for a car and a drill are quite massive products, so the bed must also be massive and, preferably, with the ability to fix the machine on a workbench. All elements are welded, as the connection with bolts and screws may not be sufficient.

The bed and the support post are welded from channels or other suitable rolled products, about 5 mm thick. The steering rack is fixed to the rack, which should be 70-80 mm longer than the rack, through the lugs of the steering column.

To make it more convenient to use the machine, the control of the drill is taken out in a separate block.

Video 5. Drilling machine based on the steering rack from Moskvich

The order of assembly of drilling desktop machines:

• preparation of all elements;
• fastening the rack to the frame (checking the verticality!);
• assembly of the movement mechanism;
• fastening the mechanism to the rack;
• drill mount (check verticality!).

All fasteners must be made as securely as possible. It is desirable to connect steel one-piece structures by welding. When using any kind of guides, you need to make sure that there is no lateral play during movement.

Advice! To fix the part in which the hole is drilled, the machine can be equipped with a vice.

On sale you can also find ready-made racks for a drill. When buying, you need to pay attention to the mass of the structure and the size of the working surface. Light (up to 3 kg) and inexpensive (up to 1.5 thousand rubles) racks are suitable for making holes in a thin plywood sheet.

Drilling machine using asynchronous motor

If there is no drill on the farm or it is not desirable to use it in the machine, you can make a design based on an asynchronous motor, for example, from an old washing machine. The scheme and manufacturing process of such a machine are quite complex, so it is better to do it by a master with sufficient experience in turning and milling, assembling electrical circuits.

The device of a drilling machine with an engine from household appliances

To get acquainted with the design, we present assembly drawings and detailing, as well as the characteristics of assembly units in the specifications.

Details and materials for the manufacture of the machine are shown in the table:

Homemade machines for drilling printed circuit boards

Mini-board drilling machines for radio amateurs also borrow a drive from various low-power devices. At the same time, cutters for cropping photographs are used as levers, soldering irons, collet pencils instead of a cartridge. The drilling site is illuminated with LED flashlights - there are enough opportunities for technical creativity.

Video 7. Mini board drilling machine

Using a conventional hand drill, it is almost impossible to manually drill a strictly perpendicular hole in a thick bar, to perform a series of precise parallel drillings. Buying even an inexpensive drilling machine for this purpose is extremely wasteful if such work is episodic.

Exist special devices for factory-made electric drills, expanding their capabilities in this regard. Click on the small pictures on the right for a closer look.

Their use allows you to turn the drill into a kind of drilling machine. Of course, you can get one of these devices by choosing it for your tool, but you can make a drilling machine from a drill with your own hands. Let's consider several approaches to solving this problem.

Do-it-yourself drilling machine from a drill, drawings

Detailed drawings of such a device cannot be found even on the Internet. This is partly due to the multiplicity of approaches and technical solutions, and partly due to the simplicity and accessibility of methods for solving this problem. Let's analyze the ones that we managed to find.

This one is perhaps the most detailed and detailed. The main advantage of this arrangement is the absence of any gear pairs that provide vertical movement of the drill along the stand, which is the basis of the fixture. The spring-loaded holder moves along the rack by the distance between it and the lower stop, minus the thickness of the compressed spring. To prevent its rotation in the horizontal plane in the rack, obviously, a groove is made along which the screw 16 moves. The place of attachment of the tool in the holder is performed based on the parameters of a particular drill.

Even easier for self-implementation is a drawing of a wooden stand for a drill.

It does not show all dimensions, due to the fact that they are not of fundamental importance. BUT lever system feed, as in the previous case, will ensure a strictly parallel movement of the electric drill along the rack. The holding of the tool in the upper position is achieved due to the friction forces in the grooves and on the side cheeks of the holder and is regulated by the tightening force of the self-tapping screws.

If you have a spare screw set, possibly from an old vise, then it can also be used for the tool feed system in a homemade electric drill stand.

For small drills, you can also use a regular threaded stud Ø 16-20 mm with a corresponding widened nut, which are sold in hardware stores.

Simple designs of homemade racks for a drilling machine

We have selected for you easy-to-make, but in our opinion interesting rack designs for home-made drilling machines based on an electric drill.

Such a wooden stand can function successfully without a lever, and the instrument is raised and lowered either by the handle of the instrument itself, or by upper part the box in which it is attached.

An interesting design in which a system of 2 levers is replaced by a 1-m longitudinal groove along which the stop screw moves.

A productive method is the combination of materials for racks that allow you to turn an electric drill into a drilling machine. So, the main material for their manufacture is wood, but the most worn components are made of metal, which radically lengthens the life of the entire device.

An interesting design using industrially produced furniture skids as guides:

The high accuracy of their execution has practically no backlash.

The process of creating a stand for an electric drill is greatly simplified if you have a photo enlarger of any model at your disposal. It is unlikely that he will ever be able to serve you for its intended purpose, but a drilling machine will turn out great from it. After all, it already has in its design both guides and a gear rack for moving a rather heavy head along them, instead of which a holder for a drill should be hung.

No less productive is the option of converting old Volgovsk or Zhiguli rack jacks into a drill stand. After all, you do not need their entire height for the normal operation of such a device, but only a small gap of the screw.

To do this, it is enough to slightly modify the lifting lever, in which to fix the drill, and the thrust pad.

And here is the video:

You can do it even easier by firmly fixing the drill at the top of such a jack, and place a work table on the lever. Do not lower the drill for drilling, but raise the workpiece itself, especially since the lower part of the screw in such jacks is the least worn.

And in general, the same principle can be applied to fairly large and powerful drills, securely fixed in any way on the powerful stand of the future machine. And you can make a small lifting table in the image and likeness shown in the video:

Or use a small rhombic car jack for the same purpose, providing it with a reliable base and replacing the upper stop with a work platform with vise or prism.

Moreover, both the first and the second can be made removable, and in long time intervals between drilling operations, the jack itself can be used for its intended purpose.

More powerful drilling machine designs

And yet, when we talk about a drilling machine, we mean something more solid than described in the previous section, and the material for such devices should be metal, even if we are talking about very small machines for low-power power tools, like this:

And even such a primitive design greatly expands the capabilities of a hand drill. But, how to make an almost full-fledged drilling machine with your own hands, without using complex technical solutions for this? Of the simple ones, the following construction seems to us the most reliable:

Its biggest drawback is the possibility of free rotation of the holder, and with it the drill, around the stand, but if instead round pipes apply square or rectangular, then this drawback will be eliminated. The main thing: very carefully choose the size of the gaps between the stand and the movable sleeve of the holder frame for the drill.

Somewhat different, but not more complicated technical solution to feed the tool to the part in which drilling is performed, a home craftsman from the video performed:

In conclusion about the choice of drill

If you only plan to pick up a specific drill model with the possibility of using it in conjunction with a device whose designs we have described above, then:

1. Give preference to a tool with a power of at least 1 kW.

2. Choose a model with a removable handle, fastened with a circular clip in the girth. They have a convenient wide cylindrical part on the body for mounting in a holder.

3. Choose a tool that has several speeds or smooth speed control.

4. The button on your drill should have a latch in the on position.

5. It is better to connect the drill on the stand to the mains through a socket or extension cord with a power button, and firmly fix them on the frame in a place convenient for emergency shutdown.

AT modern production the use of various machines has become so popular that now not a single decent workshop can do without this equipment.

Indeed, a mini CNC drilling machine allows a person to engage in such work that he can independently complete, if he can, then with the use of a huge amount of time.

This applies to the processing of metals, wood and other dense materials, which are quite difficult to use without specialized equipment. Another big plus of the machines is that making a drilling machine with your own hands is not difficult at all.

If desired, a person with basic mechanic skills can assemble a homemade drilling machine in a couple of days. It is about the assembly of home-made drilling machines that will now be discussed in this article.

1 Features and purpose

Drilling machines are widely used in industry. In fact, it was their invention that became a real revolution in the world of industrialists who wanted to quickly increase the pace of production.

Indeed, the presence of machine tools in production is a real blessing. A high-quality drilling and grooving unit is able to perform work with amazing accuracy, while reducing the requirements for the original skills of a person that uses it in work.

This phenomenon is explained very easily. Let's imagine that you need to create a metal plate with ten holes on it.

Holes should be of different diameters. From the smallest to the largest. The plate at the same time has a thickness of 3-5 mm. That is, for working on metal, you will have to use a fairly powerful drill.

Note that large drills are used by large tools, such drills are usually quite heavy. It will be difficult for an unprepared person to even hold them in their hands. Not to mention the performance of more or less lengthy work.

In addition, it should be understood that filigree precision will be required of you, because this detail is just a part of a larger mechanism.

One small slip, and the whole structure can become completely unusable. This is especially true for machines for drilling printed circuit boards. When processing boards, the accuracy of their markup is determined by tenths of a millimeter.

If you give a man everything necessary equipment, then even with experience, he will fiddle with the plate for no less than a couple of hours. When drilling boards, this time cost can double.

And this is the case if you have experience and relevant skills. If it is not there, then it can literally take a whole day to prepare only one plate. If you use a mini machine in your work, then the work time is reduced several times. It already has all the essential tool. The drill is stable and clearly directed.

All that is required of you is to correctly install the plate on the XY table, start the engine and drill a hole. Then change the position of the part and continue working on the same technology. As you can see, the productivity of production is reaching a qualitatively new level.

1.1 Parts of the machine

Now let's turn directly to the components of the machine. After all, if you are interested in the question of how drilling machines are made or how to make a drilling machine with your own hands, then first of all you need to figure out the details that will be used when assembling it.

Fortunately, a DIY mini bench drill consists of a few basic parts. The device of the drilling machine determines the quality of the device itself, but here it all depends on many factors.

So, drilling machines consist of:

• beds or bases;
• fixing rail or frame;
• device position control mechanism;
• attachments for the working mechanism;
• engine or mechanism that directly performs drilling;
• adapters, collets and other similar materials;
• all kinds of handles, stabilizing legs and other additional parts that are used to improve the design of the device.

It's worth noting that it doesn't really matter if you're looking at a benchtop mini PCB drill or a standard benchtop.

You, of course, you can use different parts for assembly homemade drilling machine, however, the general scheme and device of the drilling machine will remain the same. The difference will be only in specific details and their dimensions.

For example, a home-made desktop unit for drilling mini-boards for electronics will be mounted on a shallow frame. In most cases, you won't even need a cabinet. It will be enough to take a large heavy rail, which by its weight will be at least half the design of the device for drilling boards.

Also when developing mini boards you will need a much simpler and smaller engine, as drilling mini boards requires more fine work where power is not a priority.

1.2 Selection of parts for assembly

First of all, always pay attention to the frame or base. The base for an impressive machine must be very strong and stable. For such purposes, it is necessary to use a table with good supports, special stands, you can mount from a photographic enlarger, etc. Even a nightstand will do the right sizes and dimensions, but it's up to you to decide.

If we are considering desktop pattern, then the coordinate table here will act as the first base on which the desktop drilling machine itself is already installed. In this case, the bed can be made from a metal plate or something similar.

Interestingly, some craftsmen manage to assemble a table or a frame for a machine tool even from the ancient parts of a photographic enlarger. That is, a wide variety of parts can be used for manufacturing.

The main thing is that the table or bed on which the device is attached is extremely stable and does not give vibrations during operation.

You can make a frame for fastening with your own hands. The same is done with the mount for the working mechanism. Here you can use a metal corner with drilled holes or something similar.

The corner is fixed to the table with screws or welded to the frame. Installed there lifting mechanism. It is made from an old jack, shock-absorbing pipe, sliding rails and other similar mechanisms.

The engine will need to be powerful enough to work, so you will have to go through several options. Moreover, the table and the base of the machine must withstand its weight without any problems and dampen vibrations during operation.

A good asynchronous engine from a washing machine or something like that is suitable for manufacturing. You can use the engine from the drill or the drill itself.

2 Scheme of creating a machine

If we consider only the simplest models of equipment, which you can quickly assemble with your own hands. Then the standard scheme for assembling drilling equipment is best suited for these purposes.

However, we note right away that there are two main technologies for its assembly. The first is simpler, it consists in using a ready-made drill, which is simply screwed to the mounts.

The second one is quite difficult option, and it consists in assembling the machine from a separate engine, collets, guides, etc.

Stages of work:

1. We collect the table and the base for the mini machine, we are engaged in fixing the bed.
2. We mount the main stabilizing frame.
3. We connect the mount for the engine.
4. We are in the process of building a lift.
5. If necessary, install springs and shock absorbers.
6. We mount the working element of the machine.
7. We connect all the contacts, install the drill.

When assembling the machine from a finished drill, it will be easier for you to work. All that is required of you is to create a strong frame with the ability to raise and lower the drilling mechanism, to which the drill will then be connected.

There is no need to mess around with power supplies and engine assembly. You just need to properly fix the tool and connect it to electricity.

The assembly of the engine already provides for the installation of a power supply, a converter, and, if the engine has an indirect transmission of forces, mechanisms that are involved in their transmission.

Therefore, in order to prepare the second option more time, effort and energy will have to be spent. Yes, and certain engineering skills will not be superfluous either.

2.1 Homemade drilling machine from a conventional drill (video)

A self-made drilling machine allows you to drill holes in different materials at a sufficient quality level at home.

1 Homemade drilling machine - who needs it and why?

Drilling in an extensive list of all kinds of plumbing operations is considered among specialists to be the most accessible and truly simple procedure. It is usually performed on special drilling units, which may have different functionality and some design features. The modern machine tool industry produces many types of drilling machines, ranging from very simple ones (for example,) to CNC units that have several spindles.

It is clear that in most cases a home craftsman simply does not need such machines, since they are intended to perform serial operations. And in everyday life, it is usually required to carry out any single procedure.

It is for this reason that many home craftsmen decide to make an elementary drilling machine with their own hands, using the parts and materials at hand that are available in any private garage.

As a rule, radio amateurs, as well as people who themselves perform simple household tasks, “light up” with the idea of ​​making a home-made mini-drilling machine. repair work. In some cases, a simple electric drill is enough for this. But, if we are talking about more serious procedures, the drill, of course, is not able to guarantee the normal quality and accuracy of drilling. That's when it makes sense to start making your own mini-machine, on which you can install different ones.

2 How to make a drilling machine from a drill?

In home workshops, such drilling equipment is most common, due to its simplicity. self-manufacturing. You don't need materials high strength and any special equipment. The mini hole drilling unit consists of only four key components:

• a bed that serves as the base of the machine;
• rotation mechanism (in our case, its role is played by an electric drill);
• feeder;
• vertical stand.

The rack is usually made of ordinary chipboard or boards, since the small mass of the drill does not require the use of more durable materials. But it is better to make the frame as massive as possible. This will ensure the absence of vibrations during the drilling process, and therefore more comfortable work.

Masters advise using a relatively thick (from 2 centimeters) furniture plate for the base of the unit. The ideal option is the use of an old photographic enlarger for the manufacture of the frame and rack. It will only need to be slightly modified to get a really reliable design of a mini-machine for domestic use.

The quality and accuracy of drilling on a home-made unit depends on the correct connection of the bed and the vertical stand. Therefore, this part of the work must be approached as responsibly as possible. It is recommended to cut out two guides from steel strips, which are then connected with screws to the rack. The block with the drill will move along the indicated guides.

The block itself must be made so that it securely holds electric drill. This is easy to achieve using small steel clamps. It is also advisable to place a small rubber gasket between the block and the drill. It will significantly reduce vibration and make the operation of the installation more comfortable.

The feed mechanism of a drilling machine from a drill is a simple lever that will move the block with the tool in a vertical direction. It is desirable to provide this mechanism with a spring of relatively high elasticity and power. One end of the spring should rest against a fixed, pole-mounted wooden beam, the other - in the block.

If you want to achieve maximum convenience of working with a home-made machine and do not plan to periodically remove the electric drill, it is recommended that you simply disassemble its switch and mount a separate button on the frame, with which you will start and turn off your drilling unit. As you can see, everything is quite simple. Any more or less "handy" man is able to make himself a small and convenient machine tool from a drill.

3 Do-it-yourself drilling machine based on an asynchronous motor

Any owner in the garage, basement or somewhere on the balcony of the apartment has a lot of electric motors from electrical units that have served their time. Of these, it is quite possible to choose a motor that will become the mover for a mini-drilling machine. The ideal option in this case, an asynchronous type motor mounted on drum washing units is recognized.

Work on creating a home drilling rig based on an old electric motor is much more difficult than when using a drill. But it is quite possible to implement them, armed with a certain amount of patience and perseverance. It is important to realize here that the engine from the washer has a more serious weight. And the power of such a "motor" is much higher than that of an electric drill. And this means that you will have to take care of preparing a "mighty" rack and base for the machine being created.

Experts say that it is possible to reduce the vibration level of a unit based on an asynchronous motor by installing it on a powerful base, as well as by placing it closer to vertical rack. However, it must be remembered - proximity rack and motor is fraught with complication of the design homemade machine, which is caused by the need to install belt pulleys.

For the manufacture of a drilling installation using an electric motor from a washing machine, among other things, you will need the following parts:

• gear;
• bearings in the amount of two pieces;
• hexagon;
• two tubes of small thickness (one of them must have an internal thread);
• clamping ring (preferably made of strong, for example, tool steel).

The hexagon is required to make the moving part of the machine tool transmission. A pulley will be put on it. Also, a metal tube with a bearing and a steel ring must be attached to the hexagon. It is important to achieve a very tight connection of these components with each other, because otherwise they will completely collapse during vibration (not immediately, but quickly enough).

The adjustment complex of the unit is made of a gear and a tube on which it is necessary to make cuts. They include gear teeth. The specified tube is made such a height that the drill chuck rises by a predetermined amount. An axle with a hexagon is then pressed into the same tube.

From the described scheme, it can be seen that it is quite difficult to make a machine with an asynchronous motor. Therefore, it can be advised to do it by analogy with the previous process, when an electric drill was used. But be prepared for the fact that, unfortunately, the resulting machine will not be characterized by special drilling accuracy.
