Circular saw for router
To make a compass, a long strip 8-10 cm wide is cut from plywood. A through slot is milled in it.
On its circumference are screwed centimeter wide slats.
According to the width of the gap between the boards under the bar is sawed out insert. It is drilled in the center and a bolt is inserted into this hole. Screw in the self-tapping screw slightly to the side.

From the end of the workpiece, a groove must be made.
Then the insert is installed in the guide bar, and clamped with a wing nut. In this form, this tool can be used for marking circles. To do this, you need to make a hole in the workpiece to insert the needle from the screw. After that, by putting a pencil on the device as a compass, you can draw circles.
The main task of the device is to mill discs. To do this, they are roughly cut out of plywood or board, and with the help of a hole are fixed to the attachment. Edge of unit with counterbore rests on router table. In this way it is possible to keep the disc blank at the same distance from the cutter at all times, so that its edge is removed evenly.
Elements of construction of the self-made wood sawing machine
Making a stationary circular saw with their own hands has a number of features that must be considered.
Making a carriage for a circular saw with your own hands
The functions and operation of the device depend on the presence of various devices. One of them is considered the carriage. To construct it, you need to do the following:
- cut the plywood a little wider than the table;
- At the bottom, attach the guide bars. the interval between them should coincide with the width of the table;
- Fix the thrust bars on top.
Note! To easily clean the coating from sawing waste, it is recommended to coat it with varnish. This material is applied in several layers.
The manufacture of the carriage has a number of features
How to make a shaft for a circular saw with your own hands
The shaft is considered an important element of the circular saw. It is made of 45 grade steel round bar. At the same time, the diameter of the workpiece must match the size of the saw blades. The most commonly used is 32 mm. Saw blades should be installed between the flanges and clamped with a nut.
In order to use the saw for working with different materials, several modes of operation should be provided. Therefore, it is worth making several grooves on the shaft. They let you move pulleys and change speeds.
What kind of discs for a circular saw should be used?
These elements seriously affect productivity and quality of work. The blades can be designed to work metal or wood. In the first case, the wheels should have small teeth. There are also universal models.
Discs can be solid or carbide. The first variety is made from a single piece of high-carbon steel. These parts are reasonably priced, but often have to be sharpened. Carbide castings have a higher wear resistance, but are much more expensive.
Parallel stop for the circular saw with his hands
This is an important element that is needed when working with large workpieces. The stop can be made of different materials. plywood sheets or chipboard. On average, its dimensions are no more than 25 mm. You can fix the stop with boards or self-tapping screws.
To make a stop, it is necessary to perform the following:
- Take 3 strips of laminated chipboard and make a U-shaped profile;
- From 2 slats make a guide channel and bolt it to the end part of the table;
- Make an inverted T-shaped structure out of fiberboard. it must be screwed to the stop and placed in the channel.
Table for a circular saw with their own hands
To make a table circular saw, you need to do the following:
- Assemble from sheets Laminated chipboard top of the table. It resembles a box without a bottom. Fasten the fragments with bars. Their length should be greater than the height of the sheets.
- Turn the structure upside down and fasten the bars with additional crosspieces.
- Cut out a tabletop from a plywood sheet. In it you need to make a hole along its length with a jigsaw and place the saw blade there.
Note! To modernize the construction, instead of bars you can use a metal angle. At the bottom of the structure should make a shelf.
To get a reliable stationary design, you need to make a table On the working surface of the device must be present a marking in the form of a grid. It will help to make the work more accurate. Also do not neglect the use of protective guards. This element helps to protect the device during operation from mechanical influences.
How to make with our own hands?
Electric wood circular saw can be made with your own hands from a variety of devices. There is an important condition: you should have skills to work on metal.
From an angle grinder
Making a homemade stationary circular saw at home is not difficult. First of all, you need to decide on the project, draw a diagram and make a drawing. The difference between stationary and table homemade circular saws lies in the height of the base. Before you assemble the tool, you should think about creating the “table”. It is usually made of wood (board thickness of 3 cm) and covered with tin or aluminum sheet. Also for this purpose can suit a steel plate up to 6 mm thick. The crossbars are made from angle bars (up to 80mm).
Working wheel protrudes beyond the table usually by 35%, ie for a bar thickness of 120 mm diameter wheel should be respectively 370 mm. The power installation will need 1000 watts (or possibly more). If the workpieces are more massive, the homemade circular saw may not “take” them. the support is created from angle “8”. it is quite a massive and robust structure that can withstand quite considerable loads. The leg extends beyond the boundary of the table by 4-5 cm. One shelf is machined on both sides, the remainder in this case should be equal to the length of the table.
A very important node is the shaft. it is best to take it already prefabricated. If you have the skills to work on a lathe, then to turn such a part is not very difficult. You will need to buy bearings with protection. It is better to use a pulley with a V-belt pulley. As the engine can be suitable power plant from a refrigerator or washing machine. Capacitors are usually oil-paper ones.
After you have managed to assemble the machine from hand-made tools, you should test it without any load. All elements must be “lapped” to each other to work as a complete unit. In the process of testing, there may appear some shortcomings, they must be eliminated. For a homemade circular saw, the engine from a washing machine is ideal.
Such power units operate from 220 volts, they have a good efficiency and an acceptable rate of rotation. If you put a three-phase engine (it is powered from 380 volts), then you will have to buy capacitors to reformat the unit to 220 volts. Sometimes units with a gasoline engine are used. such power units have good efficiency, unpretentious during operation.
The most important element in the homemade machine is the shaft. It can be made of cast iron by yourself. On a lathe to make such an element is not difficult. It is important to observe the alignment of the part, so that then there is no unnecessary vibration of the mechanism. On the shaft, special grooves are milled, where the saw blade and pulleys will be attached. Sometimes also milled notches for fixing blades. The power of the engine is directly related to the size of the saw blade itself. Diameter must be greater than 3.5 times the thickness of the product. There are also proven calculations: 110 mm of material thickness requires the power of the engine from 1 kW.
Folk craftsmen often make a circular saw together with a planer on one base. Both tools can be powered by the same motor in this case. Deburring machine can clean the wooden surface to a mirror shine, its presence in combination with the circular saw is more than appropriate.
From a hand-held circular saw
It is also not difficult to assemble a circular saw from a manual circular saw. The sliding support can be made from angles, which are mounted on both sides of the rotating element (disk with teeth). The width of the slit is usually up to 5 millimeters. All edges must be roughened so that they are slightly rounded. All brackets are made with cross struts, which must hold them firmly together. Bolts and nuts can be used as fasteners.
A metal clamp must be fastened to the body. Screw tie is mounted at the bottom of the unit. Clamp (thickness up to 2 mm) in conjunction with the back post is a single unit that can withstand significant loads. The support is fixed at the back of the machine. The washers that create the gap can be moved to adjust the size of the slit between the saw blade and the sides of the stop.
Transmission is best done with lino belts. if you get a foreign object, these pulleys will slip when jamming, which eliminates the possibility of injury. On the engine is placed a pulley with large dimensions, on the shaft for the circular saw is placed a pulley with a smaller diameter. in this ratio the optimal number of revolutions is achieved.
From gasoline saw
To make a circular saw from a chainsaw, you will need a metal canopy, which will be mounted to the body of the saw. The engine is already there, so it is not very difficult to make the machine. Two channels (185×8000 mm) will also be needed. You will also need angles (55 x 100 mm) and two scraps of rails, which turn the bottoms upwards. 16 mm holes are drilled in the base of the sawmill, and the distance between them should be one meter.
Ties are made of pipe (length. 255 mm). Construction fastening is realized on the bolts. Stands are made separately, on them the body of the sawmill will be attached. It is important to make sure that all elements are not deformed. The distance between the posts should not be more than one meter. Then the sawmill is equipped with a movable carriage. It is made from a steel sheet 620×55 mm, to the bottom of the metal corners are welded. On the cart mount small bearings. At the top you must also weld two angles for fixing the chainsaw. Then a holder is made, which will work as a retainer for the beam or log.
You will need a pipe with a diameter of 45 mm. The work will require a hose, which will be attached at a given height, which should not be greater than the length of the pipe itself. This is how a sawmill is made. Process on such a machine can be a log or a log of any cross-section.
From the drill
Drill. a universal tool from which you can make such units:
Locksmiths in the service station make even winches from drills for lifting quite large loads. The drill is also actively used in construction, in particular. in painting work. Agrarians often use a drill to install seedlings in the ground. The circular from the drill will be compact. To create the tool will need the following elements:
- The base of a board with a thickness of 2-3 cm;
- vertical supports;
- The shaft on which the disk is attached;
- An electric drive in the form of a drill.
Instead of a board, you can also use sheets of chipboard with a thickness of at least 30 millimeters. On such material should be sawed a rectangle of 310×255 mm. You will also need 5 mm thick dural sheet for the work table. This material is good, because it has an acceptable coefficient of stiffness and at the same time low weight. In the planned place with a marker, a hole is cut with a size of 165×12 mm.
The fastening of the drill itself can also be made by your own hands. The assembly for the shaft with a saw can be easily found at any construction market. During work, there will be a lot of dust, so you should look for a bearing with protection. so it will be significantly prolonged service life. A circular saw from a drill is composed according to the standard algorithm:
The equipment requires compliance with safety regulations:
- The place of work should be cleared;
- The workpiece should work smoothly, without any delays;
- The machine must be equipped with a protective screen;
- debris should not accumulate on the machine and should be removed in time;
- preventive inspection of the machine should be made, its lubrication should be performed.
Such a mechanical device makes it possible to work not only on wooden products. If you put good cutters, you can work with non-ferrous metals, PVC, chipboard, bars.
Circular saw guide: bar and carriage, parallel stop
The circular saw is most often used for precise, straight cuts in wood and wood materials, but can also be useful for cutting light metals and plastic. It must have a guide for the circular saw: the bar and the carriage, a parallel stop. When buying a tool, you should pay attention to this. Power and the number of revolutions per minute. these parameters determine the productivity of labor, quality of work, the ability to saw hard materials.
Uncomplicated device for precise sharpening of circular disks and cutters
Saw blades, when they lose their sharpness, not only reduce speed, but also the quality of the cut. That’s why they need to be periodically sharpened. If you do it simply with a file on the hinge, it will not be possible to achieve a particular improvement in sawing. It is possible to saw with such sharpened disk only wood, but it does not allow to receive at once a finish cut. For qualitative sharpening you need a conductor (device). It is possible to assemble such a device with your own hands.
How To Make A Homemade Table Saw With Circular Saw
How to evenly saw a bar, a trim, a board with a “fillet
Of course, if a person has a workshop, then this question will not be relevant. Every workshop has a vice and it is very easy to solve this problem. But let’s simulate the situation that we are in the country house, from the tools we have only a hacksaw for wood. We need a very straight and accurate cut a bar or a board, a trim, it does not matter.
If we saw on the table, the bar starts to “twitch”. Press by hand is not possible, you can foot, but not always convenient. The easiest way to attach the bar is to make a simple “mare”. Let’s take small scraps.
Like this, “mare” is ready.
Let’s put this “helper” aside for now and make a marking on the bar. Some people saw a bar in one line, we will not do so. 1. Drawing the fishing line of the marking. (cutting fishing line)
Also do the fishing line on the side that will be displayed to us. (The line of control)
Also, for beginners, you can make a fishing line on the side that we can’t see. (I’ll tell you later what it’s for)
For not rough sawing, it is better to use a hacksaw with a height of “tooth” 3.5-4 mm. On the hacksaws, this information is indicated. We set the “mare”, one side rests on the edge of the table, the other side will hold the bar.
On the other hand, you can put a block to make it even.
On the line, which is not visible to us, we make a cut of 1-2 mm, it will be a guide for our hacksaw.
Let’s make a stop and start sawing with the top part of a hacksaw, about 30 degrees. First we make the cut, we already have a kerf, then we saw off the desired cut on the guide bar.
Guide for circular saw
Diagram of a home-made workbench (view from the front).
The simplest device is a guide-bar. You can easily make a straight cut. For making this, you need a straight and even bar of the required length. We attach it to the material with self-tapping screws (if allowed) or clamps. The fixing must be carried out at such a distance from the required cutting line, so that the position of the saw blade coincides with the marking when resting in the bar with the side foot of the circular saw. This method is suitable for a single cut, but if you repeat the same operations, the procedure of marking and installing the bar must be repeated each time.
The guide-bar can be improved by fixing it to a sheet of sturdy plywood 6-8 mm thick. One edge of the plate will be aligned with the cutting line when working. At the distance equal to distance between the saw blade and the edge of the circular saw’s sole (working distance), a guide bar is fastened to the plywood with self-drilling screws. When working, you will only need to align the working edge of the plywood sheet with the sawing line and secure the opposite edge with clamps.
Using the rail-mounted jigsaw
The use of the rail rail is appropriate if you need to quickly and accurately process a large number of boards. In the manufacture are used:
Metal corners are installed on the plywood base. Fastening of the corners is performed by bolts. which act as studs. in the corners of the base. Corners are placed on the same plane, strictly parallel to each other. This is to ensure that the circular saw slides freely on the rail during operation, does not jam and does not slide off it. Use the studs to set the angle fixing height required for free movement of the work material between the base and the rails. The edge of the cutting wheel must not be too high from the base while at the same time avoiding the possibility of damaging it.
For easier sliding of the saw on the corners glued Teflon strips or make a frame with wheels for it, which is preferable.
Initial material is sawn into blanks, using a parallel stop for circular saw during the sawing process. Their own hands can easily be made from a wooden bar or metal angle, secured to the workbench clamps.
Having made a marking on the workbench, the rail is exposed to the desired distance from the stop and, having set in it the end of the board, cut the workpiece.
If it is necessary to saw a workpiece at an angle, it is secured with a stop made of a pair of screws screwed into the base, and the angular inclination of the sawing is set with the help of the protractor.
Polished shafts are used most often and are inexpensive. It is not difficult to buy these elements. They are subject to mounting and machining. Mostly made of solid steel.
The top layers are then subjected to induction hardening, which has a beneficial effect on the period of use and wear rate. Perfect smoothness allows the carriage to run smoothly on the polished surface. Both ends of the shafts can be fastened with two hands without any problems.
But also on the market there are many fake elements made of low quality metal, because the probability of accurate on-site inspection is zero.
- The base is not fixed. The shaft can only be supported on the base of two mounting devices. This makes installation with your own hands much easier, but still independent of the table support. Because of this the possibility of defects during the processing of the product increases. As time passes, the guides for the lathe carriage roll and warp.
- There is sagging at long intervals. Due to sagging, shafts longer than 100 cm are not used in machining for the machine. The thickness and length of the gross surface are also important. The best option is 0, 05, and even better is 0.06 to 0.1.
