How to install a manual circular saw into a table
A detailed description of making a table for a circular saw with their own hands, which will come in handy in any workshop
Circular saw is a convenient and productive tool, which is present in the workshop of every real man. If you work with lumber in large volumes, it will be necessary to make a table for the circular saw.
Of course, you can make an individual order in a furniture company. But you can build such a table with your own hands, having the necessary drawings, materials and tools.
The design of the table consists of only two elements:
If desired, craftsmen can complement the product:
Important: the circular saw is mounted under the table, only its disk is located on the table top. The hole for the saw should be slightly larger than the disc. Thus, the sawdust will not clog the mechanism.
Such a piece of furniture should be sufficiently strong and reliable. Keep in mind, the greater the power of the saw, the higher the load on the table surface will be.
The advantages of a homemade circular saw table can also be added:
- comfort and convenience in work;
- saving money;
- high labor productivity;
- The ability to make a product based on personal needs and the characteristics of the workshop.
Requirements for the arrangement of the circular table:
circular saw is placed so that its disk was strictly perpendicular to the surface;
the most convenient size of the table is 1.2 by 1.2 meters, but of course it can be changed depending on your requirements and working conditions;
the height of the table for the circular saw depends on the height of the master, so make it based on this parameter. as you would be comfortable;
it is best when the table is standing on legs, not on a solid sheet;
The gap for the disk should be equal to the thickness of the disk plus a couple of millimeters. no more;
The saw is fixed so that it stands in the center of the table without shifting;
The control button of the saw should be located either on the table top, or under it. on the leg.
You can make a circular table with your own hands from different materials. The most common are considered:
Each individual option has its own merits. Laminated chipboard, plywood and fiberboard are easy and simple to work with. In addition, these lumber products have an affordable price. And the products made of wood have higher strength and technical characteristics.
Attention: before proceeding to the assembly of the product, all its wooden elements are treated with antiseptic compositions.
The construction of the table consists of only two elements:
If desired, craftsmen can supplement the product:
Important: The circular saw is fastened under the table, and only the circular saw blade is placed on the table top. The hole for the saw should be slightly larger than the blade. This way, sawdust will not clog the mechanism. Such a furniture item should be sufficiently strong and reliable. Keep in mind, the greater the power of the saw, the higher will be the load on the surface of the table.
To the advantages of a homemade table for a circular saw can also be added:
- comfort and ease of operation;
- saving money;
- high productivity of labor;
- The ability to make the product, based on personal needs and the characteristics of the workshop.
Before you start working it is advisable to make a drawing of the product. On it indicate all the dimensions, materials of manufacture and other important information. Making a quality drawing of any furniture item is possible with the help of special computer programs.
Making a drawing of the table, be sure to take into account the size of the circular saw. Each brand of tool will have a certain size.
If during the working process you like to leave materials on the table, the size of the table top should not be less than 120 by 120 cm.

Circular saw table
When choosing a circular saw, you should be guided by these characteristics:
- Saw power. If the amount of work is rather large, it is advisable to use a tool with a power of at least 1.2 kW.
- Cutting depth. The thickness of the material to be processed depends on this parameter. Hand saws have 40-70 mm. But when you install it in the table there will be a reduction of about 10 mm.
- Button placement. The design of the sawing table must provide free and safe access to all control buttons, otherwise you will need to finalize the control system yourself.
- Speed of rotation. For cutting wood, high RPM is a priority. This affects the quality of the cut. For plastic, for example, it’s not very good. The high frequency of rotation of the wheel heats the plastic. Medium performance must be chosen. 3 to 4,000. RPM will be enough.
Those who plan to seriously engage in woodworking, you should think about making a full-fledged stationary circular saw. It should be a separate unit mounted on a workbench, equipped with a powerful motor, with the ability to quickly change the blade. On making their own hands such a circular saw will have to spend time, but it will pay for itself for sure.
Despite the apparent simplicity of this device, before starting work, it is worth creating a drawing of the machine. This will clearly see the future unit, to choose the optimal configuration.
The basis of any machine is the base, the frame on which all the main parts are mounted. The base of the circular saw must be stable and reliable, so it is made of metal. It is preferable to use profile pipe or thick-walled angle tube. To connect the parts use welding. If demountable construction is planned, the bolted connection is suitable.
Buying a suitable material is not difficult, in any specialized hardware store you can find both the pipe and angle. If you want to save money, you can turn to scrap metal dealers. They can buy the same, only cheaper.
The best material for the table top of a professional circular saw is metal. Steel and aluminum-based alloys are excellent. For the budget version you can be limited to a thick multi-layer plywood, upholstered with sheet iron. In any case, the surface of the table top must be smooth, resistant to friction and not sag under the weight of up to 50 kg.
A groove for the disk is made in the worktop. There are two ways of making it. It is possible to make a cut in a single plate, or it is possible to assemble a tabletop from two halves. The second method is preferable for metal tabletops, where the groove is difficult to cut on the tabletop at home.
Attach a parallel stop to the worktop. The best material for this, regardless of the material of the table, is a steel corner. either by making grooves for it or by using heavy-duty clamping screws.
The motor of the future circular saw is chosen depending on the disc available. If you plan to work with small discs, 150-170 mm in diameter, you can be limited to an electric motor with a capacity of about 0.5 kW. For disc diameters of 350 mm and more you need to look for a unit of 1 kW or more.
If desired, you can make a sawing machine to work outside the workshop, it is enough to provide the ability to install a small capacity gasoline engine, it can be removable.
Transmission of rotation
Optimal drive of the circular saw. V-belt drive. Two pulleys are used, one on the motor and one on the drive shaft. It is convenient and safe. There is no direct connection between the motor rotor and the disc, in case the tool jams, the belt will start to slip, signaling the need to turn off the power. Also, by using pulleys with several arms, different diameters, it is possible to regulate the speed of the saw blade, choosing the best mode for different types of wood.
The motor rotor’s rotation is transferred to the shaft. This is one of the most critical parts of the circular saw. You can hardly make the shaft yourself, it is better to buy ready-made or order it from a turner.
The shaft is mounted on bearings. They must be of the closed type: the circular saw is a place of sawing and open ones will not last long.
Tools and process requirements
What should be the table for the crosscut saw with his own hands, it is of course decided by the master himself. Mandatory requirements can include:
- safe and sturdy mounting of the saw;
- flat and smooth work surface of the table top;
- easy access to start and stop buttons.
Homemade table can be made of wood
In stores mostly offer products made of stainless steel. But the tables for routers and circulators made of wood are not inferior to them in quality, and the service life of the material is not reduced.
You can make a table for a manual circular saw with your own hands, using the following tools in the work:
In addition, you need a tape measure and a pencil, as well as wood varnish for protective properties.
Elements of construction of the sawing machine for wood created by our own hands
To make a stationary machine at home for sawing materials, first of all you need to know what structural elements it consists of. Whether it is a machine made by your own hands from a manual circular saw, angle grinder or a tool assembled from disparate elements. the set of basic parts is the same.
The surface of the table must be made flat, for a better quality product at the output.
The main elements of stationary circulators are:
- Table for connecting and fixing mechanisms. If the circular saw is powerful and massive, it is better to use a metal table. Suitable options of particle board, wood, plywood, most importantly, that the surface was smooth.
- Shaft. The most critical detail. When making it separately use a lathe. Dimensions should be calculated accurately, this will avoid runout.
- Cover. This element ensures the safe use of the circular saw.
- Motor. When using an angle grinder or circular saw, it is part of the power tool.
For your information! If the design is supposed to be prefabricated, when creating a circular saw with their own hands, the engine from a washing machine will be the most successful option.
In the design of the circular saw there must be movable parts of the drives, and in the power supply circuit must be mounted a button to stop the motor in emergency situations.
Circular saws of any stationary type consist of the main parts.
Circular machine, as close as possible to the factory models, requires a competent approach to assembly, so before you make a stationary circular saw, you need to think through all the details. In principle, the table mini circular saw differs from the stationary one in the height of the bed, which directly depends on the nature of the work performed and the size of the workpieces that will be processed by the device. One-time work can be carried out on a compact table saw, while the circular from a manual circular saw can be easily hidden in a shed or closet, and the carpenter, who constantly conducts manipulations with lumber, will need a stationary self-made circular. Below is a diagram, which details all the elements and devices for a circular saw of this type.
As can be seen from the figure, homemade circular saws of this type have a clear design, and the drawings, such as the one presented above, greatly facilitate the process of their assembly. Before you make a circular saw, as well as mount the circular table with your own hands, consider each part of the unit separately, so that you know all the subtleties of its operation and installation.
Circular saw table
The table for the manual circular saw with a slot in the center is sometimes remade from the usual kitchen one, or assembled from planks or metal profiles. Professionals strongly recommend to cover the circular saw table with a sheet of galvanized metal, because without coating the base is at risk of abrasion in the center from the constant friction of the lumber, which in turn will negatively affect the quality of the kerf, and the depth of cut will be uneven. Cross tie, reinforcing sawing table, it is better to make from 60. 80 mm steel angle with a horizontal segment outward in order to simplify the installation of the side limiter. Homemade table, on which the circular saw will be installed, must be strong and stable, and it must be securely fixed in a fixed position.
Circular saw blade
Toothed blade must be at most one third of its diameter above the circular saw table surface, otherwise it will not cut wood properly and the process itself becomes dangerous. If you need to cut a bar with a diameter of, for example, 100 mm, the similar parameter of the cutter should not exceed 350 mm, but the engine is required here with a power of 1 kW. For workpieces over 150 mm in diameter the mini manual circular saw is unlikely to be suitable. Some factory-made circular saws have an riving knife installed behind the disk at a distance of 2 to 3 mm from saw teeth. It excludes a jamming moment due to the clamping of parts of the sawn workpiece, so it can be very useful in the case when going home-made circular saw.
Adjustable side stop
Put a quality stop is possible from a steel angle with a cross section of about 80 mm, which is 3. 4 cm longer than the construction of the table. The flat sides of the angle are bent down so that their width was one and a half cm greater than the thickness of the table. After installation the stop is fixed on the homemade circular saw table in a given position with screws. Adjustment of this element is carried out according to the template placed between it and the torch.
The shaft installed on the circular saw is the most critical component, so it should be bent out and tested together with the disc by a specialist on special equipment. The product of the pipe with a carelessly fixed circuit is excluded at once, because the slightest error in the work of this element will turn into major troubles such as equipment failure, damage to the workpiece and personal injury to the operator. Optimal solution would be to buy ready-made shaft with a seating place for the torch. It is better to give preference to ball self-aligning bearings, which have a curved inner surface, otherwise the home-made unit will quickly collapse and the shaft, mounted on a self-made circular saw, will be out of use.
In our case, the ideal option would be a V-belt drive, but it is better to abandon the rigid gear mechanism, as such a self-made device does not guarantee safety. If suddenly a nail gets caught in the lumber, the rotor of the motor will provoke disc breakage, which can lead to injury. If the inside diameter of the belt pulleys is small, it can slip, and the tensioned belt serves as a kind of damper. The gear ratio is usually selected on the basis of the engine speed, necessarily taking into account the allowable number of disk revolutions. The smaller the diameter of the saw blade, the higher the rotation speed can be and the cleaner the reworked saw unit will be.
Among self-made devices the most popular is the circular saw, assembled from the engine from a washing machine.This choice is explained by the fact that its scheme of work is best suited for such purposes. In contrast to the collector units, which are usually supplied with power tools, the motor from the washing machine operates at less high speed, which means that it shows a longer work, has higher efficiency and is not so prone to all kinds of clogs. You can also use a three-phase motor, but then there will be additional costs for the purchase of a starting and working capacitor, so it is more economical to do with a device from a washing machine. That’s basically all the wisdom.
Advantages and peculiarities of the tool
The circular saw has its own advantages: it allows you to make an even cut, increases the speed of installation, provides convenient operation, saves electricity. If you replace the disk, you can also overcome the soft metal. To make a complete tool for work, you need to set it on a table and provide an approach from all sides.
At the same time it is necessary to comply with the following conditions:
- The table must be well anchored, for which its legs are sometimes filled with concrete or bolted down;
- hand saw is fixed with iron clips to the table top to ensure safety at work;
- The grounding is necessary.
The large width of the table is an inconvenience when working. The optimum size should not exceed 60. 70 cm, so that it is convenient to hold a bar (not on the outstretched hands). If the work surface is not static, the quality of the cut is impaired, so fixing is necessary. The wire can be secured to the floor with staples to prevent accidental tripping while working.
As an alternative, you can make an additional socket under the table top.
a drawing of the tabletop must be prepared in advance, showing the dimensions. This is almost a drawing, but simplified. On paper, you need to specify the size of the gap for the disk. in width and length, where it should be in relation to the edges of the table. Immediately you will be able to imagine your work behind such a device.
The first step in creating a machine for woodworking. drawings of a sawing table. They can be not compiled, having picked up a suitable option on the thematic sites or forums. But it is better to make at least the simplest diagram yourself, taking into account the available materials and selected dimensions.
On the drawing note all the nuances that will be needed for the preparation of materials, indicate the place of attachment of supports and their angles of inclination, if the legs of the table are not perpendicular to the table top. In the drawing it is also worth noting the place for fixing the block for switching on and off the saw. When drawing a diagram by yourself it is not necessary to keep the scale and exact proportions. The main thing is to correctly specify the dimensions of all future parts for the sawmill.
The process of making: step by step instructions
Circular saw table top as a complete unit
To make a quality construction it is necessary to observe some tips. The process consists of several steps, shown in the table.
|1||Trim all sides of the block with the plane planer. Then the frame of the future table is assembled from it. In each side of the table top you need to drill several 5 mm holes. Additionally one through hole is made for the legs of the product.|
|2||Several holes of the same diameter are made in the pillars. One through hole is made in each leg. The diameter remains the same, 5 mm.|
|3||Proceed to install the dowels in the tabletop. Beforehand, they are coated with carpentry glue. Put the legs and uprights on top. If you have screw clamps with tie rods, fix the product with them. When the glue is completely dry, mount the planks and legs with special metal fasteners. In addition, it is necessary to tighten with self-tapping screws. You can add extra strength and sturdiness to your construction with the help of angle pieces. They will become an element of additional fastening, give the product stability. For the short side 2 are enough, and for the long side 3 will do.|
|4||The next step involves securing the saw to the product from the inside. There are several methods to accomplish the task. For fastening we need bolts M4 or bars with self-tapping screws. The first case is fast and reliable. The second method does not involve additional holes, which eliminates the need for drilling. It is necessary to make a cut in the bars, the width of which is equal to the dimensions of the saw’s platform. Next, self-tapping screws and bars on both sides fasten the equipment and the table top|
|5||After installing the saw you need another block of a larger size. It, using self-tapping screws, is fastened to the base of the structure. Screwing is carried out on the marks made when aligning the platform in a level position. The above manipulation will help, when removing the saw, to return it usually quickly without finding the markings|
|6||The saw blade is installed in its proper place. The base is sawn to obtain a longitudinal hole. Then turn it upside down|
|7||Then begin the construction of the parallel stop. Two strips are sawn from the plywood. Their length should coincide with the width of the table. On average, these dimensions are 10 cm. Round off the corners|
|8||The obtained strips are ground. They should be fastened at an angle with self-tapping screws. Inside, screw a metal corner|
|9||If you need to fix a stop on the base and the structure will be used frequently, you should attach the guide so that it is perpendicular to the disk. Attach the roller to the lower part. This will allow it to move.|
The construction is complete and ready to use. When performing the described manipulations it is important to remember about observance of safety precautions. Applies to any manipulation with the circular saw.
Check regularly the position of the table and its strength. The design must be stable, without loosening.

Make sure the saw is securely fastened first, only then turn it on. Do not hold the sawing material with your hands. This will help avoid getting wood in the face when the knots start to bounce. In addition, the use of special safety glasses is recommended when working.
For safety, always use protective goggles
The above simple tips will help to avoid injuries at the workplace.
