How to make a circular from a washing machine

How to make a good smoker from a washing machine drum

The cherry on the cake in our question is a smokehouse. Fragrant smoked meat, bacon and fish - what could be better for the table? If you have a tank from a top-loading car lying around in your shed or garage, consider it in the bag.

In the bottom of the tank, it is necessary to cut a hole for the firebox, weld fasteners inside for hanging products. It remains only to install the tank on the hearth, hang fish or bacon, cover the top of the tank with a lid and ignite the sawdust.

Products need to be smoked for several hours until cooked.

It is important that the fuel under the smoker is smoldering and not burning. It is better to place such a device away from home.

Circular from the "grinder"

This power tool is in the arsenal of any self-respecting master. Instead of a cutting or grinding disc, you can install a toothed saw disc.

The grinder must be securely attached to the edge of the table, ensuring that the axis is parallel to the table top. Only after this is it allowed to mount a steel toothed disk on the angle grinder.

Circular from the grinder

Just as in the case of a circular saw - it is necessary to think over a remote starting device. If the "grinder" is equipped with protection against the loss of voltage in the network, you will have to make changes to the design of the switch.

If the design is simple, it is enough to install a socket with a switch, and fix the start button of the angle grinder in the "ON" position.

All of the above applies to simple methods of processing wood blanks, that is, "parallel" and "perpendicular". If it is necessary to perform complex carpentry work, the circular requires revision.

How to make a circular machine drive

What kind of engine is needed for it? It depends on which washing machine is gathering dust in your storerooms. The engine is better to take, of course, more power.

Although for a mini-circular, which is assembled in the same way, a less strong one will do. Its difference is in its light weight and the installation of the mechanism not on a stationary base, but on a wooden box. It serves as both a bed and a chip storage.

Preparing the motor

The collector motors of the washers have several conclusions. How to identify and connect the right ones? We call the second coil with an ohmmeter, selecting with the greatest resistance.

We check other connections at the collector and brush outputs.

We also find, measure and mark the speed sensor wires. They can be located inside the case, then disassemble it.

We connect the first collector outlet and one from the coil. The second, with the remaining contact of the coil, is connected to the network. We make a test run.

To enable reverse rotation, the contacts are swapped.

We adjust the speed

In order for the circular saw to be able to cut materials of different sizes, you need a device to add or reduce the number of revolutions.

In the device from which we removed the motor, this function is performed by a tachometer acting through an electronic module. The latter will not work with our device.

The simplest thing is to use a dimmer or trigger from a hand-held electrical device to control the voltage supply and, accordingly, the speed of rotation of the shaft. The connection goes like this:

• one lead of the coil ends with the lead of the armature;
• the second - to the mains supply;
• the remaining output of the anchor through the dimmer is the same;
• after checking the connection, we test it.

A more complicated option is using a tachometer.It will allow not to lose the power of the electric drive during operation. It must be connected through a microcircuit, which will equalize the power when the load on the shaft increases. If it is impossible to buy a ready-made one using the TDA 1085 circuit board and the list of necessary parts, you can assemble it yourself.

Movement module

It consists of:

1. Shaft for attachment of the cutting disc.
2. Shaft of the engine.
3. Transmitting belt.
4. Motor pulley.
5. Saw pulley.

For simplicity, the device can be assembled without bearings.

The shaft transfers the rotation to the saw blade through a drive belt fitted to a pressed-in smaller pulley. The pulley must have a notch so that the poly V-belt does not slide over it.

A small projection is welded on the edge of the larger pulley to prevent the drive loop from slipping.

The disc must be securely attached to the shaft, otherwise it will come off and cause injury.

Rebore the engine fixing holes to adjust the belt tension.

Starter

For him, you can pick up a switch for a household electrical appliance. Better to put a push-button from a Soviet washer.

Its connection diagram is as follows:

1. At the input, it is powered by two contacts, and inside one wire is bifurcated.
2. Of the three outputs, one will be a phase, the other will be zero.
3. The third, through the capacitor, will give the phase shifted.

This connection will better ensure startup. But after it it is necessary to disconnect the capacitor.

Stanina

For a welded frame, a rectangular twenty-millimeter profile is suitable.

At the bottom are the securely mounted drive and motion module. This design leaves the upper platform free.

According to the testimony of the craftsmen who made such machines, they spent about six months on it. But they are quite satisfied with the equipment. So go for it too!

Miniature machine made from a washing machine engine

The circular is characterized by extreme simplicity and availability of materials for its manufacture. Perhaps the only expensive part is the electric motor. Stationary machines are equipped with a powerful asynchronous motor, which provides cutting of thick wood of any species, but in a home workshop, you can limit yourself to less power.

This design has several advantages. The engine from an old washing machine is inexpensive, moreover, a similar unit will probably be found in the household of a home craftsman. Connecting this motor is not particularly difficult, there is no need to look for circuits or solder. With all this, the power of such a unit is quite enough for most types of work.

The machine diagram can be simplified as much as possible by eliminating the belt drive. In this case, the cutting tool will be attached directly to the motor shaft. The base of the desktop mini-machine will be a frame assembled from a bar with a section of 40 x 40 mm. If desired, it can be welded from a corner or a profile pipe.

As a stand (tabletop) of a circular, a part of the body of an old TV, coated chipboard, is ideal. As practice shows, this part is notable for sufficient strength, and thanks to the varnish coating, it does not prevent the workpiece from sliding.

In the tabletop, with a jigsaw, two parallel cuts are made perpendicular to the cut for the disk. A movable square will slide along them, playing the role of a side stop. It will help you make an even cut, if necessary, at a given angle.

Construction requirements

The duration and safety of working with home-made equipment depends on the types of loads, modes of operation and the strength of the unit. Knowledge of the features of woodworking devices will make it possible to manufacture a mechanism that will be reliable, but simple and durable.

High rpm of the disk.Without this condition, high-quality sawing of wood is impossible, however, it is more important for the master to guarantee the safety of a homemade circular, therefore the protective devices that are usually equipped with purchased models are a role model

If the future author believes that it is quite possible to do without some of them, then this opinion is erroneous, since one careless movement often leads to injuries.
The strength of absolutely all nodes. It is not only the ability to withstand large static loads that is important, since the table can begin to vibrate due to multidirectional dynamic influences.

They are not dangerous for the master, however, they affect the quality of the cut: traces of teeth remain on the surface of the sawn timber, difficulties arise with maintaining linear dimensions.
Fire safety is the main requirement when working with wood, therefore, compliance with the rules when installing all electrical appliances is a prerequisite.

How to make a circular machine drive

Such an axis is installed on a circular table. You can fix it on the back of the tabletop with a wide bracket cut out of sheet metal. If there is a weld, then you can weld on the mounting lugs for the bolts on the sleeve. Then the engine is fixed under the table, and a belt is pulled between their pulleys.

What kind of engine is needed for it? It depends on which washing machine is gathering dust in your storerooms. The engine is better to take, of course, more power.

Alteration of the grinder

Tools and materials:

• Bulgarian;
• drill;
• clamps;
• screws or bolts;
• reducer.

Homemade circular saw device.

The easiest option is to remake the grinder yourself, but you need to remember that this tool has a fairly high power rating, which can make the work difficult. Option with disc is used 150 or 180 mm, and there must be low speed (4000-5000 rpm), because otherwise, the cutter will blunt at an unprecedented rate. Usually 3-flute cutters are used for such alterations.

Options for attaching the grinder to the table top:

1. On the clamps. Everything is simple here - 2 clamps tightly pull the tool to the selected working surface. It is quite easy to mount and just as easy to dismantle, besides, this is the only option when, after dismantling, you can continue to use the tool for its intended purpose.
2. On self-tapping screws. With the help of a drill in the body and an additional handle, 3 holes are made, into which self-tapping screws are then screwed in and attached to the working surface. A similar option is possible with bolts and nuts, which is much more reliable.
3. Using an additional detail. We'll have to contact a locksmith, so that he carved the connecting piece between the tabletop and the grinder. To fasten it, you will have to remove the protective cover, but after fastening the tool will not move anywhere. This option is the most reliable, albeit the most inconvenient.

The layout diagram of the elements of a homemade circular saw.

It often happens that there is no grinder with low speed at hand, so you can use a reduction gear. To fasten the working tools, screws or bolts are used, depending on the desire to preserve the quality of the tools.

Only in the first case, after achieving the goal, can the tool be dismantled and used for its intended purpose, and then only if it was used as a circular for a very short time. In all other cases, this option is not even worth considering, because the chance of injury during further work is 9 to 10.

Situations are different, so the protective cover is often removed. It is not worth installing it back, but as a replacement it is better to use a steel corner welded to the work surface. Such a move will be much more reliable than factory-made plastic.

How to make a circular from a washing machine engine

• If there is no desire to make holes in the case, then brackets are used, which are fixed on 2 sides.
• A circular saw in artisanal conditions, a circular saw on our own, after some deliberation, they decided to create a circular saw, immediately there were a lot of questions, I found something on the network, something I came up with myself, well.
• Circular saw device diagram.
• A stationary machine, a circular saw that is as close as possible to the factory models, requires a competent approach to assembly, therefore, before making a stationary circular saw, our client needs to think over to the smallest detail.
• The ends of the metal part, with which the handle is attached to the gearbox, are provided with holes for fasteners.

After completion, they have long bolts threaded not from below, tightened with nuts. Re-read starting from, in the figure above you can clearly see twelve thousand are given by the engine, the gearbox. Secondly, what elements does the frame of a homemade circular consist of? To fix the position of the cover, the nut is locked on top of the pipe on the frame.

A very powerful electric motor is used to drive it. Through the holes drilled, the axial handle for the circular saw is attached. Thanks to what} {it is engaged like oil will connect with the handle.

None Any self-respecting self-employed hand will scratch itself at the sight of such a promising part.

In this article, we will show you how to make a very nice lightweight and compact circular based on such an engine, on which you can solve the fiftieth board or even the 10x10 bar without any problems.

Attention! Hand assembly and further use can be dangerous! Therefore, do not accept this case if you are not confident in your skills and do not follow the safety rules!

This article is not a call to action. And remember, all responsibility for what you do rests only with you!

Frame and frame

Having compiled the details for the moving parts of the circular, it remains for us to make a reliable frame and frame for our circle. Basically, you can use the most common materials for your home circular display stand, such as a piece of thick flat slate. Cut a rectangle out of it and cut a hole under the saw blade, costs nothing. But we are supporters of capital structures, so we prefer to take sheet metal thickness 3 mm for round frame and metal corner for 30 mm frame.

In the picture above, you can clearly see what elements the frame of the homemade circle is made of. In this case, it is also welded by itself, only not a static metal corner is used as a support, but special home tables. The stand is made of two metal tubes of different diameters, which are inserted into each other, so that the round layer can be adjusted in height.

Experts insist on a welded round frame design because vibration is bad for static fasteners created with bolts. Although, if you don't have welding, as a last resort, you can make the frame out of the corners by fastening them together with bolts and nuts. The frame also welds better to the frame. So you can make a circular motion from the stirrer motor with your own hands if you have experience making different homemade products at home. Try it yourself, and perhaps you will gain some experience, which you will later share with our readers. Good luck!

A circular saw will always be needed on the farm: in the country or in a private house. However, a good expensive tool is rarely available to anyone, and a cheap analogue quickly burns out. The way out of the situation is to make a circular saw at home.

For example, there is an option to make it from a motor from an old automatic washing machine, which is a pity to throw out, and it takes up space. Such a homemade tool can cope with a board up to 5 cm wide. The advantage of this design is its weight, which is about 20 kg.

The question arises whether it does not matter which washing machine is suitable. This, than not just the power of the motor, the stronger the saw will turn out and cope with large tasks

And a low-power tool will always be needed on the farm.

He does not need a stationary table, an ordinary box will do, which will be both a support and a place for chips. The main criterion is to connect the engine correctly, otherwise the assembled circular saw will not work. However, this is not the only difficulty.

In order for the tool to work properly and cope with various tasks, not to spoil the material, it is necessary to adjust the engine speed. In a washing machine, a tachometer is responsible for regulating the speed, which is controlled by the electrical system. In a homemade tool without electronics, a different solution is required. The collector engine has several pins. To be able to find which one to connect to, it is necessary to "ring" with an ohmmeter, which remains for our client to draw conclusions in pairs. We find where the greatest resistance is.

Grinding and grinding machine

It is necessary to start first of all with the basis of the future machine. This platform can be a slab made of old chipboard from old Soviet furniture, which is distinguished by its strength and reliability. The power unit of the unit is the engine from the washing machine. There are standard studs on its body, to which you need to attach mounting angles, which you will need to purchase in advance at any building supermarket or store. Accordingly, we attach the corners to the stand or directly to the base, if this is convenient, of course.

Do not forget that simply connecting the motor from under a 220 W washing machine will not lead to anything good. It is necessary to save the native capacitor and connect the motor through it.

Since the motor shaft from an automatic washing machine is not intended for fixing various cutting or sharpening discs on it, you will need to look for an adapter for a sharpener or an adapter for emery on local electronic boards and purchase it in order to make the device perfectly.

The purchased adapter sits on a 14 mm shaft. Visually, it cannot be confused with anything - a cylindrical element that is fixed with a threaded bolt. The cylinder shaft itself has a thread M 14. A double-sided washer with flowing diameters is put on it, allowing you to install all consumables for a grinder based on an old engine from a washing machine.

On the basis of the base, it makes sense to make and install a removable table from the same fiberboard plates. To securely fix the table, on the base, you will need to use two dowels on both sides of the surface. In this addition to the machine, it is necessary to make clearances for a variety of discs.

It is important

Thus, an inexpensive but functional sharpening or grinding machine is obtained. It will last a long time and reliably, which is very pleasant, especially in the context of the fact that it was made from an old motor from a washing machine. By the way, some took this principle as a basis in the manufacture of a router, although most of this idea still seems crazy.

Simple circular from a grinder or circular saw

An angle grinder (grinder) is one of the most demanded tools of a home craftsman, with its help it is easy to cut metal, clean welded seams. In addition, using a disc for wood instead of a standard abrasive disc, the grinder can be turned into a hand circular saw (it is also called a parquet floor), and by making a bed with a table - into a stationary circular saw.

Necessary accessories

For work you will need:

• multilayer plywood with a thickness of 10 mm or more;
• switch and wire;
• cap screws;
• screws;
• wooden block 40x40 mm.

You also need to prepare a drill or screwdriver, hammer, screwdriver, pliers, ruler and pencil. With these do-it-yourself tools circular.

Of course, we must not forget the grinder itself or the hand-held circular saw. At the first stage, it will help to cut the material, and then it will take place as a working body of the circular.

Sequencing

The first step is to make a circular case. Thick plywood is perfect for this, you can use any pressed wood panels. You will need to cut out four rectangular sheets, size 40 x 80 cm. Of these, a box with a square of 80 x 80 cm is assembled at the base. Four bars are installed in the corners for ease of assembly and structural reliability.

From above, the resulting box is closed with a table top. It can be made from the same plywood, but it is better to use some kind of laminated sheet material. This guarantees the durability of the machine, will provide ease of use of a homemade circular.

A cut is made in the tabletop for the disc to exit, holes are drilled on the sides of it for fastening the tool.

The grinder must be securely fixed under the table top.The design of the latch can be very diverse, it all depends on the configuration of the machine itself. The main requirement for the mount is that it must securely hold the grinder, not allowing it to move.

The simplest fastening may look like this: two metal squares, a grinder is fixed between them with a steel clamp.

For added strength, it is recommended to use the side handle threads, a bolt with a suitable thread is screwed into it.

In the upper shelves of the squares holding the grinder, two holes are drilled. The structure is attached to the tabletop from below using countersunk screws. It remains only to block the power button, connect the grinder through an external switch.

In the same way, you can make a circular from a circular saw with your own hands. In this case, the work is noticeably simplified due to the fact that there is no need to invent a mount. It is enough to make a cutout for the disc, drill holes in the holes of the hand-held circular saw plate.

Assembly instructions

Using the motor of the washing machine, you can not just "for beauty" to assemble a circular. Such a device will be useful for assembly, sawing or construction work. For example, with the help of a circular, you can easily dissolve a 10 * 10 bar. Is this not an indicator?

How to connect the motor?

Circular saw device diagram

Connecting the motor is the main stage in the construction of a circular saw.

If it is not possible to correctly connect the motor from the washing machine, then the device simply will not work.

The difficulty is not in connecting the engine, but in ensuring stable speed control.

As mentioned above, without this, the saw will simply tear the material. To ensure regulation, you can use a voltage regulator instead of a tachometer, which is equipped with washing machine motors.

When connecting, some masters get confused, since the collector motors that are installed on automatic machines have several outputs at once. Therefore, it is not clear how to make the connection.

The connection is as follows:

1. First, the motor must be rotated several times in order to find the excitation coil or shoes. There must be 2 or more wires from them.
2. Using an ohmmeter set to minimum resistance, we ring each output in turn. Here you need to find the two with the greatest resistance from all the available outputs. This is the case if there are more than two wires.
3. After that, you need to find the engine manifold and brushes, from which two wires should also go.
4. After that, you need to find the outputs of the tachometer. Often these wires can be found right on the case. If they are not there, then they are hidden in the case, then you will have to disassemble the engine a little.
5. Now you need to take one wire from the collector and connect the wire from the coil to it.
6. The other collector wire must be connected to a 220 V network.

If necessary, you can change the direction of rotation by simply rearranging the wires. We make a test run, having previously marked the wires of the coil and the tacho sensor.

If the engine starts without problems, then everything is done correctly. Separately, you can consider the process of connecting the engine using the speed controller:

1. We connect one of the coil wires to one of the armature wires.
2. We connect the other to the network.
3. We connect the second armature wire to the dimmer.
4. We connect the other output of the dimmer to the network.
5. We try to start the engine.

Moving parts

After the engine is connected, you can proceed to creating a circular. The next step is the assembly of the movable elements, since it is they that bear the basic load, namely:

1. Motor shaft.
2. Saw shaft.
3. Drive belt.
4. Motor pulley from the washer.
5. Saw blade sheave.

The design itself is simple, but there are a lot of points that are important to consider, for example:

1. It is recommended to grind the small pulley by making 4 transverse grooves, this is necessary so that the belt clings and does not slip.
2. It is not necessary to use a drive belt from a washing machine, you can take any suitable main thing so that it has transverse serrations in it.
3. The saw shaft must be as reliable as possible, which also applies to the nut and washer. Otherwise, the saw may deform, or even jump out and damage the working person.

Bed and frame

After assembling the moving elements, it remains only to make a reliable frame and bed. Considering that this is an ordinary homemade circular saw, almost any material at hand can be used as a bed. For example, a sheet of flat slate. All that is required is to cut it to the required size and cut a hole in it for the saw blade.

Slate will be enough, but if you want to make a high-quality and reliable saw, then take a metal sheet with a thickness of at least 3 mm. And for the frame, you need a metal corner of 30 mm.

To weld a circular frame, you must:

1. Weld from the corners two metal squares (or rectangles, depending on the expected dimensions of the saw) of the same size.
2. Next, connect with four corners of the same length.
3. In the upper part, two more corners are welded across the main square. This will be the support for the bed.
4. From below, exactly the same two supports are welded only transversely with respect to the upper ones. This will be the support on which the motor rests.
5. Now it remains to weld the legs from below, assemble and connect all the elements, and the saw is ready.

Causes of breakdowns

408-105 Stator for angle grinders Hitachi G18SE3 and HAMMER. Photo 220V

The most common reason for the failure of the grinder's stator is a violation of operating conditions. Asynchronous motors have the ability to maintain speed regardless of the magnitude of the applied load. This is both an advantage and a disadvantage.

The ability to perform work under heavy loads is accompanied by overheating of the tool, which contributes to the occurrence of malfunctions in the rotor and stator windings during long-term operation. Under the influence of high temperature, the protective layer of the insulating coating burns out, which leads to the failure of electrical components.

conclusions

When working with even the simplest structures, it is better to prepare the project documentation in advance. This approach minimizes assembly errors.
