Homemade circular saw from a manual circular saw. How to make a machine from a circular saw with your own hands? Security requirements
The primary processing of wooden materials often consists in cutting them. Several types of tools can be used for execution - from manual to electric models. The most effective is that you can do it yourself.
Circular saw design
At the first stage, it is necessary to understand the design features, to determine the optimal manufacturing scheme. It directly depends on the characteristics of the work performed, the dimensions of the workpiece, the type of wood. Only after that can a circular saw be made with your own hands.
The main component of the saw is a disk, on the end surface of which the cutting teeth are located. They can differ not only in geometric dimensions, but also in the angle of inclination relative to the plane of the disk. To perform cuts, an electric motor is provided in the design. It can be connected to the disc directly (through a shaft) or with the help of a drive torque transmission system. This tool is designed to perform longitudinal and transverse cuts, in some models it is possible to make angular, relative to the plane of the workpiece.
Before you make a circular saw with your own hands, you should choose the depth of processing. To do this, you need to familiarize yourself with the classification of equipment:
- small - from 40 to 46 mm;
- medium - from 55 to 55 mm;
- large - from 65 to 70 mm;
- professional - from 65 to 140 mm.
For housework, it is enough to choose a model with a small or medium cutting depth. If complex processing of materials is necessary, a hand-held circular saw is required. To make vertical cuts, you can make a homemade sawmill.
For woodworking, it is necessary to choose discs with a positive sharpening angle. Otherwise, the wood fibers will not be cut, but torn apart.
Table design for a circular saw
The main component of the future design is a do-it-yourself table. It will house the power unit, cutting tool, control unit and additional components to get the job done.
There are two fundamentally different schemes for designing a table. In the first case, it is designed to work with a hand saw. The main task of the support frame is to fix the workpiece and the ability to change the direction of the cuts. Most often, wooden components are used to make a table with their own hands - chipboard sheets, slats and timber.
The sawmill is one of the varieties of circular saws. The difference lies in the lower location of the disc. In this case, the table acts as a bed. It houses the power unit, there is a disk attachment unit, as well as a control system.
During design, the following points must be considered:
- motor power. For housework, it is enough to choose a model with a specific power of up to 800 W;
- cutting depth. Depends on the geometric parameters of the disk;
- rotation frequency. To form an even color, this characteristic must be at least 1600 rpm;
- location of the control unit. It should be as far away from the disk as possible.
The dimensions of the homemade design depend on the dimensions of the workpieces. For the manufacture of a manual sawmill, it is recommended to use a metal sheet as a countertop. Additionally, stiffeners are mounted at its base.
When choosing a factory saw model for completing a do-it-yourself table, you should provide for the possibility of fastening at the bottom of the tabletop. To do this, you will need to make an additional transitional mounting block.
Making a circular saw with your own hands
Drawing up a manufacturing scheme depends on the actual availability of consumables. Most attention should be paid to the design of the table. In addition to functionality, it must be stable, withstand maximum pressure without changing its position.
First you need to make a countertop with your own hands. To do this, markup is performed on the sheet material. It is best to take a tool and mark the cutouts according to its dimensions. With the help of a milling cutter, a recess is made for mounting the tool. Then you need to install additional components:
- workpiece stop. This is a wooden rail that is attached to the table top. Its position can be changed relative to the disk;
- grooves for emphasis. They are milled on the surface of the countertop;
- yardstick. It is installed at the leading edge of the disk. It is necessary for the formation of blanks of a certain width and length;
- clamps. They are an additional component. With their help, the part is rigidly fixed on the table for processing its surface with a hand tool.
After that, according to the actual dimensions of the tabletop, it is necessary to make support legs. To do this, you can use wooden bars 40 * 40 mm or steel corners. To improve stability, stiffeners are attached between the legs. The saw control unit must be located at the workplace. RCDs and fuses must be installed in case the maximum load of the electric motor is exceeded.
For greater convenience, a hand-held circular saw can be mounted on a table. This design will help you quickly and easily process and saw wood parts.
Working with a circular saw mounted on a special table greatly simplifies the sawing process and is safe when using special devices.
In this article we will tell you for a hand-held circular saw with your own hands.
Circular saw table design
The table base for a circular saw can be wood or metal.
The tabletop is made of metal or sheet wood materials. A hole is made in it for a circular saw blade.
Supports run along the guides in the tabletop, which move the timber and any other sawing material.
First of all, the table should be comfortable, stable (do not stagger!), The surface of the tabletop should be flat. These factors will help a person avoid injury during work.
The hole in the base is cut for a specific brand of saw
Before you start cutting the material and assembling the circular table, you need to calculate its dimensions and make a drawing.
The hole in the base must match the dimensions of the circular saw platform. For each brand of saw, this will be a specific size.
The plate installed on the countertop should not outweigh the table in one direction - the base must be resistant to external mechanical loads.
The dimensions of the countertop must match the flow.
For some, a folding table is enough, a small table with a removable circular saw. People who have a spacious workshop need a full-fledged table for a circular saw or even a circular machine.
Note: if it is planned to leave materials on the table during work, then the area of \u200b\u200bthe countertop should be at least a square meter. The optimal size for such a table is 120 x 120 cm.
Materials from which you can make a table for cutting wood:
- solid wood;
- Chipboard, chipboard, MDF, plywood;
- metal (steel or aluminum).
Plastic is not well suited as a material for making a saw table.
Prior to final assembly, all wooden parts of the table should be protected from moisture and decay.
To make a saw table with our own hands, we need the following materials:
- Chipboard or plywood 21 mm thick;
- timber for the table frame (you can use a edging board 50 x 150 mm 3 meters long - 5 pcs.);
- wooden dowels 10 mm - 12 pcs.;
- joiner's glue;
- metal fasteners for the sides and legs - 4 pcs.;
- metal corners - 10 pcs.;
- self-tapping screws.
Necessary tools for work:
- pencil, marker, tape measure, meter;
- jigsaw;
- manual ;
- Sander;
- sandpaper of medium and fine grit;
- plane;
- drill;
- screwdriver
Step 1. To begin with, we trim all sides of the beam with a planer. We assemble the frame of the table from the timber: on each side of the tabletop we drill two holes of 5 mm for dowels for each side and one hole for each table leg.
Step 2 In the sides you need to make two holes (5 mm), and in the legs - one each (5 mm).
Step 3 We install the dowels in the countertop, after lubricating them with wood glue. From above, the tsargs and legs are installed.
If there are clamps with ties, you can fix the table with them. After the glue has completely dried, the sides are fastened to the legs and to each other with special metal fasteners for tables and pulled together with self-tapping screws.
Note: the table will be stronger and more stable if you use metal corners for additional fastening of the tabletop: two on the short side and three on the long side.
Step 4 Now you need to fix the circular saw on the inside of the table top. There can be two options here: fasten the saw platform with M4 bolts or fasten the platform using bars with self-tapping screws. The first option is faster and more reliable. The second option does not require drilling holes in the metal platform for bolts.
Step 5 You can fix the saw with bolts or bars with self-tapping screws. We will fasten with bars, so in small bars we make a drink as wide as the saw platform. With bars with self-tapping screws on both sides, we fasten the circular saw to the table top.
Step 6 When the saw is installed, we take another larger bar and fasten it to the tabletop with self-tapping screws (directly to the points noted earlier, along which the saw platform was set evenly). This bar is necessary so that in the future, when removing the saw from the table, you can quickly return it to its place without resorting to marking.
Step 7 We install the circular saw blade in place and saw through the countertop to make a longitudinal hole. Flip the tabletop.
Step 8 We make a parallel stop. To do this, we saw off two strips from plywood with a length equal to the width of the table and a width of about 8–10 cm. We round the corners with a protractor and a pencil.
Step 9 We grind both strips and fasten them with self-tapping screws at an angle. Inside we fasten the metal corner.
Step 10 With constant work with a table for a circular saw and the need to fix the stop on the tabletop, a guide is fixed perpendicular to the disk. The roller or the second part of the guide is attached to the bottom of the fence so that the fence can drive up / drive away from the circular saw blade.
Workplace safety
In order not to be injured during work, it is necessary to carefully monitor the position of the saw table, its stability, strength.
Before each switching on of the circular saw, it is necessary to check whether it is well fixed in its place.
It is strictly forbidden to hold the cut material with your hands! This can lead to injury to the fingers or the tree bouncing in the face if knots and bumps get into it.
Also, be sure to wear protective goggles during operation to avoid injury to the eyes.
Do not neglect these simple rules, take care of your own health.

A circular machine is the tool that no home craftsman can do without. This equipment is especially relevant for a country house or cottage. But working with a manual machine is not always convenient, and factory machines are quite expensive.
The way out of this situation can be to make this device with your own hands. The basis of this machine can be not only a hand-held circular saw, but even an electric drill or grinder.
Making a frame for a circular machine with your own hands is very simple. For the manufacture will be needed the most ordinary lumber and quite a bit of time.
Before thinking about the design of the upcoming machine, you need to calculate the load to which it will be subject. The main thing in the bed is reliability and stability. For powerful production saws, the basis is a welded reinforced metal structure. But for do-it-yourself use, such a unit is not needed.
If you have just decided to make your own woodworking machine, then you need take into account the main parameters equipment. Since saws can be different, naturally, the design of the frame can also be different.
First of all, you need determine the power of the tool. As a rule, for home use, equipment is chosen where the power parameters do not exceed 850 watts. But, for example, when building a summer house or a country house, it is often necessary to saw a very large amount of wood.
That is, the power of the circular is required more. But experienced craftsmen do not advise buying saws where this figure is more than 1250 watts. Installing this equipment in a home workshop is absolutely not justified. And working on it will only increase the cost of electricity.
The greater the productivity of the machine, the more stable the base is needed for it. For professional circulars, as a rule, a base is installed, welded from steel profile. Sometimes these beds are even concreted into the floor. Since the vibration of the device can lead to danger to life.
Technical features of circular machines
Depth of the intended incision. This parameter determines the thickness of the material that will be processed on your machine. This indicator in semi-professional and professional machines ranges from 5-8 cm. This is quite enough for cutting boards and thick plywood.
But it will be inconvenient to work with logs on this machine. In addition, it must be taken into account that this characteristic of a homemade saw decreases. The depth of the cut will be approximately 1 cm less. But this can be avoided if the table frame is provided with the ability to lower or raise the disc.
When making a tool with your own hands, you need take into account the frequency of its rotation. If you need a circular for the procurement of building materials, then this figure may be less. If you need a clean and even cut, then the speed is needed quite high. This is necessary, for example, for the manufacture of furniture.
But even in this case, there are certain nuances. This saw is not suitable for cutting plastic materials. Due to very high tool revolutions disk is warming up and the plastic starts to melt.
Therefore, it is better to choose an apparatus where the rotational speed is not more than 4500 rpm, in this case the frame for a circular saw can be make from wood. The vibration of this machine is low and additional strengthening of the table is not required.
Well, in the end, what needs to be considered is the location of the buttons and other controls on your machine. When assembling the saw with your own hands, do not forget that access to the control panel should be safe. This rule is all the more important in the case when the open part of the saw is at the bottom of the table top.
In this version, the panel with switches is best placed from the outside of the machine or make a rising tabletop. This design is also convenient for servicing the device. Then, when you have taken into account all the nuances and little things, you can begin the direct assembly of the table.
Making a circular saw with your own hands
The simplest version of the frame for the circular is a structure made of boards and thick plywood. Moreover, the tool itself is attached to the bottom of the stationary tabletop. A special slot is made for the saw in the table lid.
The dimensions for the table can be changed as it will be convenient for you to work on it. For example, an average table is described, the height of which is 110-120 cm. But a lot depends on the height of the person working with the equipment. Also, according to your desire, you can change the length of the tabletop.
If you plan to work with boards that have a length of more than 2.6 m, then the cover on the frame will need more. In this case, it is necessary to make changes directly to the design and additionally add some supports(legs). Otherwise, the table will create strong vibrations.
For countertops usually plywood is used, which has a thickness of at least 5 cm. But you can also choose plexiglass or fiberglass slabs. But professionals do not recommend using chipboard, this material is not reliable enough.
Tools and materials for assembly
For a circular saw, it is imperative to provide guides. They help to cut wood much more accurately. This design welded from steel and fixed to the lid with clamps.
It is undesirable to fix stationary guides, since later you will not be able to change their position.
To build a table, you will need the following materials:
- sheet of iron;
- plywood sheet;
- beam size 50 × 50 mm;
- board size 50 × 100 mm;
- steel corner for guides;
- two clamps;
- hand circular saw.
You also need to pre-prepare all the tools that will be needed to assemble the table:
- Screwdriver, electric drill.
- Hacksaw or electric jigsaw.
- Measurement tools (tape measure, square, ruler).
- Hand mill or milling machine.
When everything is prepared, you can begin to assemble the table itself. Sometimes craftsmen collect countertops from unnecessary dining or kitchen tables. But this design is unlikely to last long. Therefore, it is much more reasonable to make all the structural elements with your own hands. In this case, you can also take into account your personal needs.
Making a tabletop for a circular machine
The assembly of the table begins with the manufacture of the countertop. The plywood sheet is marked so that the two edges of the cover are in size with the edges of the iron sheet. Plywood is cut with a hacksaw or a jigsaw.
The edge of the saw cut can be processed with a cutter, but this operation is optional. Since in the frame the main parameter is reliability, and not an attractive appearance. The tabletop is rubbed “roughly” with sandpaper.
From the bottom of the tabletop mark slot for circular circle. Why first you need to measure the dimensions of the sole of the unit. The easiest way to do this is to unscrew the disk from the device and simply circle the desired part of the saw. These measurements are required to determine the footprint.
With the help of a hand cutter, bars are selected to a depth of approximately 0.9-1.1 cm. If you do not have a cutter, then this work can be done using a chisel, but it will take much more time.
Then, when the seat is made, try on the saw and, if necessary, correct the recess. Mark the slots for the circle and fix the fasteners. If you want the circle to rise and fall, then you need to install pendulum mechanism for table top.
In this case, the slot must be made in the form of a truncated pyramid. In this case, the hypothetical top of the pyramid will be directed downwards. Directly frame for hoist is best make from steel that are welded to each other.
Making a table frame
The markings for fixing the transverse rails and longitudinal ones, which act as stiffeners, are best installed on the wrong side of the countertop. The planks themselves are made from a bar. You will need:
- Two transverse parts, long equal to the width of the countertop minus 7-9 cm on each side.
- Two longitudinal ribs, equal in size to the length of the cover minus 7-9 cm on each side.
Then you need make nests for screws. The slats must be fixed on the lid so that the tabletop extends 7-9 cm beyond the edges of the frame. The fasteners must be as reliable and durable as possible.
The first fastener must be installed approximately 40-50 mm from the edge of the rail. The distance between the screws is approximately 23-25 cm. All details need to drill through. The self-tapping screw is attached from the side of the lid so that its head is completely recessed into the tree.
First fix the transverse ribs. To make the table cover as strong as possible, the edges of the rail must first smear with carpenter's glue. The structure is fixed with clamps, and without removing them, screws are screwed in.
The tabletop is allowed to dry completely. After that, the longitudinal rails are installed in the same way. Then the parts of the frame are pulled together with two fasteners on each side. Now the clamps can be removed.
Mounting legs (supports)
Table legs are made from timber. The height of the supports is selected individually. In practice, it is most convenient to work at the machine when the worktop located at hip level. Before fastening, each support must be planed so that the leg descends from below to an angle. So, the area of the base of the support should be slightly larger, in contrast to the area of the top.
It is best to secure the legs with steel corners. They need to be slightly pressed so that the base of the machine is in the "strut". This gives the table extra durability. Bolts with washers are used as fasteners, they are fastened with caps outward. Otherwise, during operation, you can be injured on the protruding parts of the fasteners.
The whole structure will be more stable if additional supports are pulled together with diagonal rails. They are attached in pairs from each side of the machine.
Cover surface polished and varnished or use a steel sheet for coating, which is mounted on self-tapping screws. At the very end, on the prepared place, the tool is attached directly.
On the table top additional markup, it will help to cut wood evenly and correctly. The control panel of the circular saw is located on the outside of the machine. As a rule, it is mounted on one of the legs of the table. That's all, the circular saw with your own hands is ready.
The main component of a carpentry home workshop is a circular saw. It is intended for primary processing of materials by manual or automated method. Due to the high cost of factory equipment, craftsmen most often come to the conclusion that it is best to make this machine with their own hands.
Requirements for household circular machines
Structurally, it should not differ from factory models. They consist of a support table, in the center of which there is a slot for a saw blade. In addition, the design contains measuring components, elements for fixing the workpiece and for ensuring the safety of work.
Before manufacturing, it is necessary to familiarize yourself with the basic requirements for its components. It is important that they fit each other not only structurally, but also in terms of technical parameters. To do this, you can take a diagram of a typical design of a factory woodworking machine.
Complete set of woodworking saw equipment:
- table. Must have sufficient stability, the surface of the countertop is perfectly flat;
- power point. The main parameters of the electric motor for rotating the disk are power and number of revolutions;
- additional components. These include stops for fixing a wooden workpiece, rulers for measuring.
The advantage of home-made models is the ability to choose its dimensions, performance and other technical parameters. In the process of drawing up a manufacturing scheme, you can choose the optimal height of the table, the dimensions of the tabletop, and the characteristics of the electric motor. This does not have a hand tool for woodworking.
Requirements for woodworking discs directly depend on the parameters of the workpiece, the type of wood and the required productivity speed. This is calculated on an individual basis.
Materials for the manufacture of a circular machine
After drawing up the optimal drawing for the manufacture of stationary equipment with your own hands, you need to select consumables. To do this, you can purchase rolled metal or use existing components.
The main problem is the choice of the power unit. Some recommend installing a factory-made hand saw. However, often they do not have the necessary power to process large volumes of wood. In addition, the limitation on the diameter of the disk will reduce the functionality of the equipment. Therefore, it is best to choose drawings in which there are two separate blocks - an electric motor and a shaft for mounting the disk.
The connection of the load-bearing elements of the desktop is carried out by do-it-yourself welding. Mechanical components will not provide a proper indicator of reliability, as backlash will form due to constant vibration.
- table. For legs, you can use steel corners 30 * 30 or 40 * 40 mm;
- countertop. It is made of dense chipboard, although experts consider the use of a steel sheet to be the best option. In this case, a lattice structure is made in the upper part of the table;
- electric motor. You can use any household model of a 220 V asynchronous power plant, the power of which does not exceed 1.5 kW, and the maximum number of revolutions is 2400 rpm;
- a system of pulleys for transmitting torque on a shaft with a disk. Pulleys are best taken from the factory. A tensioning system must be provided.
To fix the workpiece along the length, it is necessary to provide a support bar. It should shift relative to the plane of the disk, thereby adjusting the width of the board being processed with its own hands.
Before welding, all steel blanks must be cleaned of rust. Painting is carried out only after the final manufacture of the saw machine with your own hands.
Assembling a homemade circular machine
After preparing the components, you can begin to assemble the structure on wood. Drawings are drawn up in advance, on which all the parameters of the elements are indicated: dimensions, welding places, mandatory processing zones.
First, the frame of the saw machine is assembled with your own hands. It is necessary to provide places for mounting the shaft with the disk and the electric motor. Pulleys should be located on the outside. This is necessary for the periodic tightening of the transmission belts and the prompt implementation of repairs.
According to the diagram, a slot is made in the center of the tabletop through which the disk will pass. The edges of the material must be processed, but the countertop must be even. The plane of the disc must be strictly perpendicular to the surface of the table. Recommended slot dimensions: width - up to 5 cm; length - up to 400 mm.
The motor control unit is located in front of the cutting area. This will help prevent chips from getting into electrical components.
To get acquainted with an example of making a circular saw with your own hands, it is recommended to watch the video material:
It is difficult to imagine the workplace of a carpenter or joiner, where there is no stationary circular. Many craftsmen make a circular woodworking machine with their own hands. There are no particular difficulties here, you just need to decide what will be taken as the basis. For yourself, you need to set a goal, and then outline the ways to achieve it. Select suitable devices that will be used in the process of creating future technological equipment for the workshop.
Some specialists use not one, but several machines. Large parts of future pieces of furniture are made on fairly powerful equipment. When assembling, it is sometimes necessary to make additional components. Therefore, small portable machines are used, which are easy to operate away from home.
What can a wood sawing machine be made of?
For the home workshop use:
- Special shafts with fasteners for the disk and electric motors of sufficiently high power. Such equipment can work with large-diameter circular saws, which will allow sawing rather thick workpieces.
- Angle grinders (grinders) produce different capacities for discs of various sizes. The frequency of rotation of the shaft with the tool reaches up to 12-15 thousand rpm. Therefore, the cut quality is very clean. Some craftsmen like to use machines based on angle grinders.
- Hand-held circular saws (RDP) are initially equipped with a wood disc and a fairly convenient casing that can remove chips from the sawing area. Many RDP manufacturers, when developing the operating instructions, attach diagrams of the possible installation of the tool in the countertop. The kit often contains auxiliary fasteners that facilitate such installation.
- A conventional electric drill can also help in creating a small circular machine. It can cut small parts from plywood, boards and chipboard.
- If necessary, sawing large workpieces and even tree trunks is adapted by chain saws. With their help, you can create not just a small machine for sawing boards and bars. A small home sawmill is being made, it will allow you to recycle wood from the garden or the nearest forest.
How to start manufacturing a machine?
Any machine equipment that is supposed to be operated stationary is placed in the table. These tables can be made:
- to full height. The top level of the countertop is placed 75-80 cm from the floor;
- desktop. Small machines mounted on stands or small tables. They are made low (up to 30-40 cm). It is convenient to take such machines with you on a trip; they fit in the trunk of a car or in a trailer.
May be required:
- profile pipes 25 25 (30 30) mm. Using such blanks, rather light frames are obtained, which are then sheathed with boards, laminated plywood or chipboard. Today it is the most technologically advanced material. But welding is required, and experience with a welding machine;
The frame made of profile pipes is characterized by a small mass. The shaft is rigidly mounted on it
- rolled corners 32 32 (40 40, 50 50) mm. The frame is getting heavier. Differs in rather high durability. Sheathe similar metal frames with wood or metal sheets with a thickness of 6 mm or more;
Corner table 50 50 mm. The machine is highly durable
- wooden blocks 40 40 (50 50) mm. For the manufacture of such a frame, there is no need to use welding. All connections are made with self-tapping screws. For greater rigidity, use glue;
Convenient to cut to size
- Chipboard allows you to make simple tables. Assembly is carried out on confirmations or self-tapping screws;
- plywood with a thickness of 15 mm and above is a fairly convenient material for making a table for a future machine. You will need to additionally protect the product from moisture.
Plywood is easy to cut to size. For ease of marking, squares and steel rulers are used.
Circular saws are used for sawing. They are produced in a variety of versions:
- from high speed steel. Such disks are made on stamps. Further sharpening and setting of teeth is carried out. A similar tool is used for rough sawing of workpieces. Most often it is in demand for carpentry with boards;
Stamped circular saw made of R6M5 steel
- with brazed hard alloy plates. Such discs are distinguished by a high culture of performance. After sawing with such a tool, an edge is formed, which is often not processed.
Saw blade with soldered blades made of T5K10, VK-8, VK-10 alloys. Such saws are rigidly attached to the shaft. Beat eliminate
For the manufacture of the machine you will need tools:
- circular hand saw. At the manufacturing stage, guide rails are used, they allow you to perform long and even cuts in the facing material;
- electric jigsaw. With the help of this tool, it is not difficult to make a complex figured cut of workpieces;
- electric is needed for screwing self-tapping screws and confirmations;
- angle grinder is used quite widely. It is equipped with cutting or cleaning discs. Some factories even produce saws for sawing wood;
- a manual screwdriver will be needed to accurately fix individual parts on the machine.
- pliers help to perform complex fasteners;
- a soldering iron is useful for soldering wires, soldering terminals;
- measuring tool: tape measure, caliper, metal rulers and squares;
- pencils and markers will help mark the details on the workpieces.
The result should be a homemade circular machine. It will include a number of basic mechanisms. They will help manage the equipment being created.
Combined sawing and planing machine
For comfortable viewing click on the image
The classic scheme of a home-made woodworking machine assumes the presence of not only a sawing (circular) part. Additionally equipped with a planing table and a shaft. After the completion of sawing, additional processing of lumber is carried out on the jointing part, eliminating existing knots and burrs.
For those wishing to repeat the classic scheme, additional drawings are provided. Using it, you can make a universal woodworking machine.
Creating the first such equipment, you can stop at a less complex model.
The simplest machine equipped with a shaft and an electric motor. Even the engine from the washing machine is adapted for such equipment.
Bulgarian as a saw drive
A positive quality of any angle grinder is a high shaft speed. For most models, it exceeds 12,000 rpm. Therefore, the quality of the cut is quite high.
Adjust the angle grinder in different ways. The options for fixing the tool to the tabletop are shown below.
Fixation inside the wooden frame
Fixing the angle grinder with the M8 bolt on the gearbox
Mounting on a swivel base. Small window hinges are used here
A frame is made from a metal sheet, which is rigidly fixed from below to the table top.
A complex frame for installing a grinder. This design will allow you to firmly screw the tool to the table.
Manual electric circular saw at the base of the machine
Most modern craftsmen are guided by the creation of a circular saw machine for manual sawing of wood. Attracts the presence of a powerful revving electric motor and ease of installation.
For installation in the countertop, it is enough to fix the tool from below, and then cut the groove. When using plywood, it is easy to make a turntable.
The saw itself is set along the axes so that in the future there will be no difficulties in the manufacture of auxiliary equipment.
Fastening is carried out with countersunk screws or self-tapping screws.
Manufacturing options for such a machine are shown below.
For hand tools, a special case is made. Sawdust will be sent to a strictly designated place
With the help of a plastic clamp, two start buttons are set to the “On” position. A separate switch will be installed on the remote panel
An interesting manufacturing option is shown in the attached video.
Step-by-step process of creating a small circular machine with your own hands
Making a desktop machine from chipboard is quite simple. How to make it yourself is shown in the table.
 | The body is cut from laminated chipboard. Parts are connected using auxiliary rails. Such a connection allows you to get a rigid body. |
 | The cover (table-top) is established from above. It is mounted on self-tapping screws screwed in the corners. Before mounting the countertop, you need to countersink the holes. Then the caps of the screws will not interfere with the work. |
 | On the countertop, a hand-held circular saw is attached from below. To do this, holes are drilled in the support frame. The length of the self-tapping screws is selected so that the sharp fasteners do not come out. |
 | If desired, a stand can be made from below. Then you get a full-size machine. Often such machines are made with collapsible stands. For field work, folding goats are used. |
 | Ball retractable guides are screwed on the side. A carriage is installed on them (a device for parallel movement along the table). After the carriage is made, it will have a cut groove. |
 | For sawing long pieces in a straight line, a parallel stop is used. Most often it is a metal corner, which is installed with a certain gap. When installing such an emphasis, measure the distance from the disk to the corner. It should be the same on both sides. Then the sawn object will not be clamped. |
 | Structurally, a similar element looks as shown in the photo. Fixing in a predetermined position is carried out with nuts. Professionals use wing nuts or special handwheels. They are quite convenient to fix the corner in the desired size. |
 | The disk is installed from below. Modern circular hand saws have adjustable blade offset. It is enough to loosen the stop bolt, and then change the inclination of the tool to the site. |
 | Some craftsmen use a vertical board as a parallel guide. Additional lines are placed here. Then, when performing complex work, it is easier to control sawing according to the specified parameters. |
