How to make a circular saw out of an angle grinder

Operating rules

The use of structures such as homemade saws equipped with discs in wood processing imposes certain responsibilities on their owners.

In addition to a table well fixed to the floor and a protective cover on the disc, it is necessary to organize the supply of sawmill material in both directions: from right to left and back. Boards and slats cannot be moved along the bed during circular operation with your hands, for this you should use a bar or its analogue made of wood. It is not recommended to be near the rotating blade at a distance less than 25-30 cm.Do not keep your hands close to the saw. fingers can be injured.

You need to turn on and off the circular saw using a button located either on the side or in front of the unit. When the disc rotates, it is forbidden to stand behind it or in front of it.

Necessary materials

To make a homemade machine, you will need:

  • rectangular pipe, steel or aluminum corner;
  • chipboard sheet, dense plywood 12-14 mm thick;
  • bolts, nuts, washers;
  • metal strips, plates, large-sized corner pieces;
  • welding machine with electrodes;
  • electric drill or drilling machine;
  • angle grinder;
  • saw blade;
  • connecting wires, on / off button.

Depending on the capabilities and needs of the master, other materials or tools may be needed. It is impossible to provide a complete list of components, since the design of the machine may be complicated, additional elements or functions may be added.

How to make a circular from an angle grinder with your own hands?

Almost every private building has a utility room. It most often stores building materials and tools, implements and agricultural machinery.

This article will discuss how to independently make a circular saw based on an engine from an angle grinder using improvised tools left over after repairs.

The nuances of using a homemade circular

It should not be overlooked that the angle grinder, by its main purpose, is an angle grinder. Therefore, using it as a homemade circular saw, you need to pay attention to the nuances.

  • Duration of continuous cutting should not exceed 15-20 minutes in order to avoid overheating of the motor.
  • The standard protection on the blade is in no way suitable for a circular saw. The protective cover can be used from a real circular or made by yourself.

It should be remembered that the rotation speed of the grinder can be more than 10,000 rpm. this is several times higher than the speed of woodworking machines. At this speed, the wood begins to smoke. In addition to an unpleasant odor, fire is possible.

Required tools and materials

To make a circular with your own hands you will need:

  • angle grinder;
  • Electric drill;
  • Welding machine (possibly);
  • Screwdrivers and pliers.
  • Steel corner 25 mm or aluminum 50 mm;
  • Steel plate;
  • Bolts and nuts;
  • Tube segments.

The circular angle grinder will be connected to the network using a switch, which, according to all the rules, must be placed on the panel from the side of the worker. It must be available at any second.

You may need something else, but the home workshop is designed in such a way that much is replaced in it. Therefore, a strict list will not stand up to scrutiny. You will need some kind of fasteners or screws, pieces of wire and insulation.

Manufacturing

Consider the assembly procedure for a stationary saw machine, as the safest and most functional device. Step-by-step instruction:

make, circular, angle, grinder
  • Preparatory part. It is necessary to create a working drawing, think over the design, clarify the dimensions and set of functions. This step is important and should not be ignored.
  • Purchase and preparation of the necessary materials and tools.
  • Assembling the table base. A base for the machine is assembled from a rectangular pipe (or corner). Sections of the required length are cut and welded together. It is necessary to ensure the stability and strength of the base. Alternatively, it can be made from wooden parts.
  • A chipboard or plywood sheet is installed on the surface of the base, which will serve as a desktop. A slot is made in it for a saw blade.
  • An angle grinder is attached to the work table from below using curved metal plates. Holes for screwing in handles are used. Depressions are made on the surface of the table so that the bolt heads do not interfere with the movement of the material.
  • For the convenience and safety of turning the machine on and off, it is recommended to bring the wires from the start button of the tool to the side edge of the desktop, for which a piece of a corner or a bent metal plate is used. The button must be located as conveniently as possible so that there is a possibility of emergency shutdown of the circular from any position.
  • The sliding stop, which allows you to adjust the width of the cut parts, can be made of various materials. Both the simplest devices, like a bar fixed with clamps, and more complex structures are used. There are a lot of options, but the choice is due to the needs of the owner and the nature of the work ahead.

The creation of additional devices requires the development of some experience and skill in using the machine. The specific design of the angle grinder allows you to work for about 15-20 minutes, after which a break is required for cooling. Given this circumstance, it is not necessary to count on a wide range of functionality.

Hand-held circular saw from an angle grinder

Greetings to all those who like to tinker, I propose for consideration the instructions for making a simple attachment for an angle grinder, which will allow you to turn it into a circular saw. It is no secret that circular saw blades can be put on an angle grinder, but this is unsafe, since the risk of a wedge of such a blade is high. So that because of the wedge the angle grinder does not cut off your hand or something else, a guide is made for it. Also, thanks to the homemade guide, you can cut quite smoothly. Be sure to make a protective shield for such a homemade product.!

Materials and tools used by the author:

List of materials:. circular saw blade (which will fit an angle grinder);. sheet steel;. bolt and screw;. nut or tap for threading.

Step one. We make the base First of all, we will make the base, it will be a steel plate, with which we will rest against the cut material. The author did not find the sheet steel needed to be thick, so he welded two thick sheets and cleaned the weld well.

Finally, we drill a hole in the base, a countersunk screw will enter into it, that is, it should not protrude above the surface. This screw will thread into the angle grinder and thereby secure it to one side.

Step three. Finishing touches At the end, cut out and weld in place another fastener that will allow you to screw the angle grinder from above. We again need a piece of thick sheet steel, we weld everything securely, we clean the welded seams to make sure of their quality.

Also in this top plate we drill another hole for the handle so that it can be rearranged as convenient for you. When everything is ready, it remains to paint the homemade paint on metal.

Step four. We install the nozzle on the angle grinder, it is screwed on with a screw and a bolt, we tighten everything well, there should be no backlashes. We put a disc for circulars on the shaft of an angle grinder, or you can use a special three-tooth disc for grinders, it is safer.

You can work, the author easily cuts fairly thick boards. In the photo, the boards are burning, probably the author’s discs are already dull.

Construction of a homemade circular from an angle grinder

  • Hand circular saw from an angle grinder;
  • Stationary circular.

The first option involves the use of the tool as a hand-held electric saw with a slight modification. assembly and installation of a stop that limits the depth of penetration of the disc into the material and protects against jerks and sudden movements. It will not work to do with the usual installation of the saw blade as a cutting wheel. the slightest misalignment will cause jamming, a sharp jerk or other dangerous reaction of the tool, which can result in serious injuries.

The simplest way is to install a stop, which is a flat platform that slides over the surface of the workpiece. It is attached to the tool with clamps or bolted into the handle hole. Some craftsmen make a platform from metal corners located on both sides of the disc at a short distance (2-3 mm).

In any case, a hand-held circular saw from an angle grinder is too dangerous and does not allow good control of the cutting line due to the installed protection. In no case should you take it off, since sawdust flying into your face can cause injuries.

Attention! The standard protection that comes with an angle grinder is not suitable for use with a saw blade. Have to do it yourself.

Creating a stationary version with your own hands allows you to get a safer and more convenient sawing machine for wood, which has almost the full functionality of a conventional classic circular saw. The main element of such a machine is a table in which a slot is made for the disc. An angle grinder is attached to the bottom side. It becomes possible to install an adjustable stop that allows you to adjust the width of the cut strips. Depending on the possibilities and need, you can make a device for facing and cutting the same workpieces of a given length.

The rotational speed of the angle grinder shaft is three times higher than the maximum speed of a conventional saw blade, so it quickly dulls and wears out. To create a regular saw blade operation, some craftsmen use a reduction gear. This allows for optimal rotation speed, reduces the risk of overheating and injury, but significantly complicates the design. Finding a ready-made gearbox is not easy and costly, so usually only an angle grinder is used.

The structure usually consists of the following components:

  • bed (base);
  • Desktop;
  • motor and drive shaft (in our case, both elements are replaced by an angle grinder);
  • stop designed to adjust the width of the cut parts;
  • a platform sliding along longitudinal guides, allowing you to cut parts of a given length (optional, manufactured as required).

An example of a circular machine for wood

Important! If the saw blade is mounted directly on an angle grinder, without a reduction gear, only high-speed or carbide types that can withstand high heat have to be used.

How to make a “circular” on wood from an angle grinder with your own hands?

A circular saw is useful, and sometimes a must for the DIYer. The owners of private or country houses are constantly renovating, creating, rebuilding something. The main material is wood or its derivatives. plywood or chipboard, which must be cut, cut into blanks or parts.

The purchase of a manual circular electric saw requires costs, and the creation of a stationary circular with your own hands is impossible without a working shaft and an electric motor. A good way out of the situation would be to use an angle grinder as a drive mechanism, which is equipped with a seat for a saw blade and has its own electric motor. You only need to create external equipment that turns a regular angle grinder into a kind of circular (circular) saw.

Safety engineering

From a safety standpoint, the idea of ​​using an angle grinder as a saw is very dangerous and undesirable. Too high rotational speed of the disk, unreliable fastening of the tool, inability to install high-quality protection. all these factors unanimously demand to abandon the idea and turn to other options.

However, if a decision is made, the following requirements must be considered:

Make A Homemade Circular Saw | Angle Grinder Hack | DIY Tools | Diamleon DIY Builds

  • stability, immobility of the bed;
  • rigid fastening of the tool, the impossibility of vibration or movement of the angle grinder;
  • using only high-speed saw blades.

In addition, it is necessary to follow the general rules for working on a circular machine, the main of which are:

  • the presence of hanging ties, sleeves, ends of clothes is excluded;
  • it is forbidden to move workpieces with bare hands in the immediate vicinity of the saw blade;
  • if the workpiece is jammed, immediately turn off the machine and eliminate the problem;
  • start work only after reaching full rotation speed;
  • it is forbidden to brake the disc after turning it off with hands or foreign objects, you must wait for an independent stop.

Compliance with safety rules is a prerequisite for working with woodworking machines. They are considered the most traumatic group of industrial equipment, therefore, the safety rules cannot be ignored in any case.

Final recommendations

it should be reminded once again that the angle grinder is designed to work with a different material and in its own speed mode. Statistics indicate a large number of accidents associated with the use of self-made devices based on an angle grinder. Using it as the basis for a circular is a problematic and dangerous solution. The creation of the machine should be carefully considered from the point of view of safety in order to protect yourself from the possibility of serious injury.

How to make a circular from an angle grinder with your own hands?

Almost every private building has a utility room. It most often stores building materials and tools, implements and agricultural machinery.

This article will discuss how to independently make a circular saw based on an engine from an angle grinder using improvised tools left over after repairs.

Necessary tools

To work, you will need tools, building materials or pieces of parts of the assembly parts of old furniture.

  • pliers, screwdriver, adjustable wrenches, hammer;
  • metal sheet, corners, nuts, bolts, screws, fasteners;
  • angle grinder and electric drill, switch and socket;
  • screwdriver, ruler.

Design features

It is possible to carry out work on transforming one type of saw into another using old elements left over from repairs. With locksmith skills and ingenuity, you can easily cope with this task.

Distinctive features of this type of device are that there are circular saws from an angle grinder as a home-made machine or manual device fixed on a table or other base.

If you have an old angle grinder, then the engine is best removed from it and used as the core of the future saw. A washing machine motor is also suitable.

Any circular has several main components:

  • homemade table as a stable frame;
  • saw stand;
  • angle grinder motor;
  • slip stop;
  • a bar for adjusting the cutting height;
  • reducer, saw blade.

This machine is suitable for cutting small wooden beams. When it is planned to process wood in large quantities and large dimensions, it is better to purchase ready-made production equipment. Its cost is high, however, for business, this purchase will be the ideal solution.

To work safely on a circular saw, you should be careful when choosing a blade for it. an angle grinder is a complex tool and you cannot use a disc from it for cutting wood products. It can jam at any time.

Rotating at a very high speed, such an element is able to crush the tree into chips, from which you can get injured. This is because there is a high temperature load on the disk during processing. It is best to purchase a new product specifically for the circular saw.

If the circular is fixed to the floor, then the frame should be fixed with fasteners (corners) to ensure its stability. For the manufacture of the bed, you can take an unnecessary cabinet or several sheets of chipboard. However, it is safer to make it out of metal.

make, circular, angle, grinder

The main work surface of the countertop is best made of plywood or laminated chipboard. The table must be very firmly on the floor so that vibration is negligible.

A more complex option involves the installation of additional elements: a pulley system, a belt drive. With this method of manufacturing, a homemade structure will take the form of a production machine. The presence of a belt will reduce the speed of the disc rotation.

Step-by-step instruction

The process of making a circular from an angle grinder with your own hands includes a number of stages:

  • first of all, you need to make a base table;
  • install the angle grinder itself and the disc;
  • attach the stop bar;
  • supply electricity;
  • test run.

The main element of both the mini-sample and the stationary version of the circular is the frame table. You can make it using the drawings, or build it to your liking, observing the basic principle of making such a part of the saw. Everything will depend on the size of the wood material that you are going to cut in the future.

We will show you how to convert an angle grinder into a miniature circular grinder. With its help, you can saw bars, small boards, slats used in repairs or in private households.

The table looks like a workbench, the base of which is most often made of lumber.

  • First, they take the chipboard sheets and hammer them into a miniature table, the legs of which are made at such a height that an angle grinder is placed under the bed. Attach them to the stiffening ribs. Those, in turn, are made of small boards and fixed along the edge of the tabletop at a distance of 7-10 cm from its bottom side using self-tapping screws.
  • It is advisable to make the upper work surface of laminated plywood. When the tabletop (bed) is ready, it is turned upside down and marked for the installation of an angle grinder and a file disc. An element from an angle grinder is taken as a basis, measurements are made on it for a slot for a new disc. At its ends, the extreme boundaries of the future hole (slots) are marked with a pencil. Then they take a drill and drill the formed points.
  • A stop bar is made from a metal corner or from a plastic trim of an old plinth. It can be mounted on plywood or chipboard. In length, this bar should be the same as the working surface of the table. Screw the bar (stop) at a distance of at least 2 cm from the saw blade teeth. At the ends of the rail, two holes are made and fixation is carried out in the table using bolts or ordinary self-tapping screws.
  • The board or block to be cut must fit completely on the table top, since the lumber is subject to vibration when the blade moves at high speed. It is impossible to keep the lumber in weight. there is a possibility of serious injury.
  • At the next stage of work, an electrical outlet is fastened from the inside of the mini-table, through which a wire is passed and then the switch is installed. Usually, its fixation is carried out from the outside of one of the stiffening ribs. The wire from the switch is directed to the power source. thus the electricity is supplied to the circular.
READ  Which way the angle grinder turns correctly

When the saw is ready, make a test run and cut small blocks, paying attention to the speed of rotation of the blade.

Craftsmen, in order not to make a table for a circular, use a vice as a support frame. At the very beginning, a clamp of an angle grinder is made with a disc on the edge of a regular table by removing the protection and unscrewing the handle of the angle grinder. Then plywood or chipboard is taken to form a frame in which a hole is made for the disc. They fix it by drilling a hole, a bolt is inserted into it. It should line up with the hole on the angle grinder where the handle is attached. The bolt is tightened to the stop using a wrench.

A stop bar or limiter is made from scrap materials. They fasten it with bolts at the ends of the bed using ordinary self-tapping screws. Under weight, the angle grinder can tilt forward and attach the disc to the tabletop itself. In this case, a handle is needed. It can be unscrewed from an old seaming key and screwed into an angle grinder, making a support for the engine.

Such a miniature self-made construction works clearly, cutting the slats and beams produces high quality.

Operating rules

The use of structures such as homemade saws equipped with discs in wood processing imposes certain responsibilities on their owners.

In addition to a table well fixed to the floor and a protective cover on the disc, it is necessary to organize the supply of sawmill material in both directions: from right to left and back. Boards and slats cannot be moved along the bed during circular operation with your hands, for this you should use a bar or its analogue made of wood. It is not recommended to be near the rotating blade at a distance less than 25-30 cm.Do not keep your hands close to the saw. fingers can be injured.

You need to turn on and off the circular saw using a button located either on the side or in front of the unit. When the disc rotates, it is forbidden to stand behind it or in front of it.

Security measures

To avoid eye contact with small wood when sawing, as well as chips, it is imperative to work with glasses. Care should be taken to make sure that the sawing is done in a well-lit room or that the circular saw is in an area open to sunlight.

When working with cutting material, make sure that there are no nails or large knots in it. This circumstance can provoke a breakage of the disc or a change in the direction of a moving bar or rail. In the best case, the engine can be damaged and the disc dull. In the worst case, the building material escaping from the hands will injure the person who is engaged in sawing or people who are nearby.

Do not turn on the circular saw with wet hands. It is strictly forbidden to carry out work under the influence of alcohol. Cuttings of sawn material can only be removed from the working surface of the bed when the cutting blade is at a complete stop.

Thus, anyone who knows how to work with construction tools and who has the skills to make wooden or metal structures can make a circular at home. It is necessary to follow the rules for operating the unit. Such a saw will become your assistant in the future and will significantly reduce labor costs for processing sawn timber used in a personal household.

How to make from an angle grinder

An old working tool can be used to make a circular saw.

For work, you should prepare a sheet of plywood, blocks of wood, a wire, a switch, a hammer, a jigsaw, a drill. For work, it is recommended to adhere to the following sequence of operations:

  • cut 4 rectangles from plywood (40×60 cm);
  • connect them in a box. To do this, use wooden blocks in the fixation points. This will give the structure strength and stability;
  • cut out a large sheet of plywood, which will serve as a tabletop;
  • cut a thin slot on one side of the tabletop through which the cutting part of the saw will pass;
  • fix the angle grinder in the lower part of the tabletop using strong fasteners;
  • wire the switch to the angle grinder.

Such simple actions will lead to the appearance in the workshop of a circular saw made by hand from available materials.

Homemade circular saw: from an angle grinder, washing machine and drill

Home craftsmen make a lot of effort to fill the workshop with all sorts of tools and devices. Thanks to this, they are able to perform a large number of operations and processes on their own. One such tool is a circular saw. It can be made with your own hands from scrap materials.

How to make a washing machine out of a motor

If an old washing machine is gathering dust in the household, the engine of which is in working order, it can be used as a basis for making a circular.

Remove the brushes, collector and speed sensor wires from the body. For reliability, it is recommended to check them with an ohmmeter.

Connect both collector outputs and coil contacts into a whole structure. It is imperative to check the operation of the device by connecting it to the network.

To change the direction of rotational movements, the contacts must be swapped.

You can increase the functionality and reliability of the circular saw by equipping it with a device that will increase or decrease the rotation speed of the cutting blade. A dimmer or trigger of a hand-held electric tool is used as such a device.

After making the base of the saw, you can start arranging the tabletop. To do this, use a metal frame on which the machine’s engine is welded.

How to make from a drill

The drill can also be used to construct a circular. To begin with, it is recommended to make the bed in the form of a strong, durable and stable table. Attach the legs to it, and make a slot on the surface for a convenient movement of the cutting disc.

Turn the tabletop over and, at a short distance from the slot, attach a rectangular block of wood with bolts. First, cut a round hole in the middle of the bar, the diameter of which is equal to the size of the chuck of the used drill.

Then take a second piece of plywood the same size as the countertop. Make another slot at the same distance as in the bed. When aligning both sheets, the slots should match exactly. The second sheet is laid on top of the table top.

Place a block on the slot in the top plywood sheet, the dimensions of which must be the same. The bar will act as a guide.

It is possible to ensure the strength of the connection of all wooden elements as a result of their gluing and bolts.

Having an old washing machine, drill or angle grinder on the farm, you can build a functional and reliable circular saw with minimal costs with your own hands.
