The advantages of homemade tools

In the economy, very often there is a need to saw a board, chipboard, fiberboard, plywood and other similar materials. It is most convenient to perform such manipulations, using for this purpose a stationary machine, which is popularly called a circular saw. It is even possible to saw firewood on such a machine, so you don’t have to think much about the rationality of making it.

Angle grinder or angle grinder has gained wide popularity, as it is a versatile tool for cutting metal, stone, concrete, plastic and even wood. However, woodworking not only requires special skills, but also caution. After all, it is in the processing of wood that such an effect, such as a kickback occurs. That is why experts recommend using the tool only as a circular grinder, which eliminates the possibility of backfire, as well as increasing the efficiency of the power tool.

Making a stationary machine from an angle grinder for wood sawing has a number of advantages:

You will need the following:

  • Screwdriver, pliers, hammer, and adjustable wrench.
  • Metal sheet metal, bolts, angles, screws, fasteners.
  • Electric screwdriver, ruler.
  • Electric drill and angle grinder, socket and switch.

Below we will consider how to make this device with our own hands.

Step-by-step instructions for manufacturing

The process of making a circular saw from an angle grinder by your own hand will include several steps.

  • To begin with, you will need to make a table-frame.
  • Install directly an angle grinder and disc.
  • Attach the blocking bar in order to create a support.
  • Make sure the power is on.
  • Carry out the initial start-up in order to check whether the machine is functioning properly.

Note that the basic elements for both the miniature model and the stationary version of the circular hand saw will be a table-frame. You can make it according to the drawings, or you can make it to your own taste and observe the basic principles of such a part of the saw. It will depend on the size of the wood material that you plan to saw in the future. We will talk about how to modify an angle grinder into a small-sized circular saw. With its help, you can saw bars, boards of small size, laths, which are used for repair work or for private households.

The workbench

The table will be made in the form of a workbench, with its base most often made of lumber:

    First take sheets of chipboard, and then make a small table out of them, and its legs should be made at such a height that under the bed could fit an angle grinder. Fix them to the ribs, which in turn should be made of small boards, and fasten them along the edge of the worktop at a distance of 7 to 10 cm from the bottom side with self-tapping screws.

But the upper part of the worktop is best made of laminated plywood. When the frame (tabletop) will be ready, you can turn it downside down and make a marking for installation of the angle grinder and the saw blade. As a basis it is necessary to take an element from the angle grinder, and on it to make measurements for slots for a new disk. On its ends mark the slots with an ordinary pencil, and then arm yourself with a drill and drill the points formed.

When the saw is ready, you should make a test run and cut small bars, and pay attention to how fast the blade rotates. This will be the end of the tool making process. Home masters, not to make specially a table for a circular saw, as a supporting frame use a vise. In the beginning it should be done to clamp the angle grinder on the edge of the easiest table, remove the protection and unscrew the handle from the angle grinder. Next, you can take particle board or plywood to form a base, in which the hole will be made for the disk. Attach everything by drilling a hole, and then insert a bolt. It must coincide with the hole on the angle grinder, where the handle will be attached. The bolt should be tightened to the stop using the special wrench.

Use whatever tools are available to make a stop bar or even a stopper. Bolt the resulting element to the ends of the frame with the usual self-tapping screws. Under the weight of the angle grinder can tilt forward and snag the table top with the disc. In such a case, a handle will be needed. It can be unscrewed from the old key for rolling and screwed into the angle grinder, making a prop for the electric motor. Such a miniature self-made design works clearly, and also qualitatively carries out sawing of beams and slats.

The design of a homemade circular grinder from an angle grinder

Regardless of the design features, each circular from the angle grinder, which make their own or buy in stores, consists of:

In the form of motors for homemade machines is allowed to install a variety of available options. It is often recommended to use asynchronous motors that are purchased directly for the machines, motors from washing machines, drills or angle grinders. Either option has a number of its own advantages and disadvantages.

Buying motors for the appropriate purpose, it is possible to choose its parameters for your device. advantages, as such, there is not. The only disadvantage of this acquisition is a high price. In fact, the cost of the motor exceeds the cost of hand-held power tools. Therefore, it is possible to make a little extra and buy a ready-made machine. For many people it is not affordable, and the expediency of such purchases is absent.

Another solution. the motors from washing machines. This way will be optimal if you have a functioning engine with such unnecessary equipment. For homemade machines will not suit any washing machines. Many modern automatic machines are equipped with a motor, for the management of which it is necessary to use a special controller.

Naturally, you can make your own efforts to assemble the controller, but it is too much time and money. To the motor from an old washing machine is quite easy to connect, because their shaft is already equipped with a pulley. The presence of such a motor will greatly simplify the creation of a circular saw. The disadvantages of such devices include their low power. As a result, we get an incomplete machine model, but a fictitious device. But it is worth noting that in certain situations you can also use this solution.

The drill, if used as a drive for homemade circular machines, has a number of certain advantages, compared to the previously presented devices. The key advantage is the elimination of the gearbox.

In general, an electric drill has low speed and high power. The saw blade is directly driven by clamping its axis in the drill chuck. The disadvantages of such circuits are the need for breaks during the working process. This is because the drill is not designed for continuous types of work and it needs to stop for 10-20 minutes every 10 minutes of work with it. This problem can be partly solved by installing additional ventilation on the motor, but it will significantly complicate the machine design.

The use of angle grinders, also called angle grinders, actually has no known disadvantages. First of all, its motor has a high power. The presence of such a tool can boast many men, if not, it can always be purchased, in any case it will be useful for the main purpose. At the same time it is quite easy to integrate it into the machine.

Often included in the package angular grinding machine provides the presence of clamps, thanks to which it is easy to mount on the bed. Installation of the pulley on the shaft is as simple as possible. Because of the high revolutions in the engine of the device, there is good ventilation, because there is a built-in cooling system, which is able to function without stopping.

To construct a circular machine, using an angle grinder, is within everyone’s power. No special knowledge and skills are required. Here you need to dive a little creativity and diligently do your task. At the very beginning of making a machine, you should be sure of your intentions and decide whether you need it? It is important to consider that despite its resistance to continuous work, the angle grinder can break because of the heavy load.

Having the intention to open its own production of furniture and wooden products at the industrial level, of course, it is worth buying a full-fledged circular machine. Homemade device is suitable for home and cottage purposes, as a tool that allows you to solve domestic, everyday tasks.

Circular saw from an angle grinder: the technology of making an electric saw

The circular grinder is an indispensable tool that is very important not only when sawing firewood, but also when carrying out repairs in the house or apartment, as well as the manufacture of furniture, etc.п. The circular saw itself is quite expensive, but you should not be in a hurry to spend money on its purchase. Such a tool, you can make from an angle grinder. How to do it? This is what this material deals with.

Circular saw machine from a manual circular saw

To ensure maximum safety when working with the circular saw machine, it is recommended to bolt the table to the floor. The tabletop should be as thick as possible. To increase the degree of strength, you can cover it with thin metal sheets. This will also increase sliding of the workpieces and make the work more comfortable. The main difference between the machine and the table type of design is that the angle grinder is not mounted above the table, but under its surface.

Use self-tapping screws, clamps and other specially prepared parts for safe fixation. A slot in the tabletop should also be about 4 mm on each side of the circular disc. If necessary, the machine can be equipped with bar elements fastened with self-tapping screws.

It is important to observe safety rules. It is advisable to equip the machine with protective plexiglass

Feed the workpieces with other blanks. Remember that the lower part of the disc must rotate towards the mower. Do not stand on the same line as the mower disc, because the disc could come off at high forward speeds. During work, the master must be as vigilant and cautious as possible.

Hello, dear modelers! I think everyone has faced the problem of making slats for their projects. That’s why it was decided to build a circular saw on the base of an angle grinder. The idea is not new, on the Internet it is already written set of packs, well allow me to insert my five kopecks. I warn you that the circular grinder (especially made by your own hands) is a dangerous tool! I, as the author of this article, am not responsible for your life and health.

To build this machine, we need:1) angle grinder (with a maximum speed. 10 000 rpm)2) wheel 125mm for wood (with speed. 10 000 rpm)3) sheet metal thickness of 4 mm. и 2.5 mm.RPM disk and angle grinder must match, because if you overrevolution angle grinder can disc fly, and at low cutting will not be clean.

First I cut out a “table” of 450 mm in size from a sheet of metal 4 mm thick (better to take 5 mm). at 340mm. and a cutout for the disk. Then I tried on the angle grinder with the disk. Marked where it will be mounted, drilled a hole and screwed it on with a bolt. The second fixing point is on the angle (about this below).

Next, from a sheet of metal 2.5 mm. bent corners. After fitting the entire structure, it was pre-assembled on bolts and nuts. After making sure that the angle grinder was not loose, but well secured, the bolts and nuts were replaced with rivets. Soviet wood screws were used to make the rivets. Thickness of cut 2.2mm. Saws cleanly, happy with the result)

And now a bit about the operation of this device. First, on and off the circular saw is done with the switch on the carrier (that is, the angle grinder must be turned on during assembly and DO NOT FORGET THAT). The work on it should not last longer than 15-20 minutes, so that the angle grinder does not overheat. And most importantly, obey the safety rules!

Thank you for your attention.Sincerely Yegor. P.S

I want to wish you Happy New Year and wish you good luck, happiness, health and creative success! And let all be well in your life!)

A circular saw, or simply a “circular saw”, can come in handy to any man during major home repairs, and simply in the household. And if you need it, you don’t have to run to the store to get it. You can take an angle grinder and spend a little free time and with your own hands turn it into a circular saw.

How to make a circular grinder with your own hands? No special blueprints or professional skills are needed. It takes a little patience and the availability of some tools and improvised means in the house:

Trim saw

Trimming, that is cross cutting of boards or bars at right angles is better if you use a special device.

From the angle grinder can also make such a machine with their own hands.

  • To do this, angle grinder with wood disc is mounted on the swivel bar perpendicular to the direction of the length of the board, so that the plane of the disc is directed strictly vertically. One attachment point should be located near the gearbox, and the second. on the opposite end of the machine.
  • The gear housing has threaded holes for fixing the standard handles. With the help of angles and these holes, the angle grinder must be attached to the moving part of the machine.
  • Rear part of the casing is secured to the board with a clamp. The blade guard can be used from any appropriately sized power tool.
  • Closer to the vertical support you need to fasten the thrust angle. It should be placed strictly perpendicular to the plane of the disk, both in vertical and horizontal directions.

The spring at the end of the guide bar is used to return the mitre saw to its home position after finishing the cut. Horizontal table must have a cross groove, in which the saw blade enters when you cut the board. disc diameter is chosen according to the width of the boards. This way the trimming can be done in one run. The main thing is that the inner hole of the disk should coincide with the mounting on the gear axis.

When working with this machine, please note that the drive power is not designed for a heavy load. That’s why the rotating saw blade must be brought smoothly to the surface of the workpiece to be sawed, and the cut must be made without strong pressure.

  • Profile pipe 20×20 and 25×25 mm;
  • door hinge;
  • 50×50 mm corner;
  • diamond-shaped jack;
  • 20 mm strip;
  • furniture board or plywood 20 mm;
  • saw blade;
  • nuts, bolts.

From a profile tube are welded 2 U-shaped blanks of the machine table with legs of convenient size.

These are welded together with two jumpers.

To make the mechanism for blade outreach adjustment a T-shaped piece is welded from a pipe of larger diameter. In length it should be 1 cm shorter than the distance between the tubes of the table top base.

The resulting part is welded to the table frame through a hinge.

Then, from the thin sections of the angle is made 2 eyelets, which are screwed to the angle grinder through its regular holes for a removable handle.

The eyelets are welded to the adjustment mechanism rod on the hinge. Ensure that the angle grinder gearbox does not protrude over the frame. If it turns out so, the lugs should be welded by displacing downwards.

At the bottom of the table, between the legs, crosspieces are welded. Then they are connected to each other by a tube running down the center directly under the adjustment bar on the hinge.

Next we need to refine the diamond-shaped jack. A wheel with a handle is welded to its adjustment screw. A sleeve is welded into its bearing area, whose length corresponds to the width of the frame profile tube. Two eye bolts made of strip are screwed to the sleeve.

It is necessary to drill the edge of the rod with an angle grinder, and screw the jack to it by means of eyelets. Then it is welded to the crosspiece at the bottom.

A saw blade is mounted on the angle grinder.

A tabletop of panel or plywood is fastened to the table. Then the angle grinder is started and the jack is lifted. The saw blade makes the cut for itself.

On the table top edges the grooves are milled transverse to the saw blade direction.

With their help a pipe is screwed to the machine with wing bolts, which will serve as a parallel stop when sawing.
