The frame for a crosscut saw with their own hands
Table for trimming saw with their own hands: preparation of materials and tools, assembly
To begin with, let’s understand what a coping saw is, and why it is needed. It is worth noting that this is primarily an electric tool designed to work with lumber. Secondly, the main feature of this tool is the ability to cut exactly at the right angle the ends of wooden parts.
Of course, such a tool is necessary to have in the carpentry workshop, with a large amount of work. How to make such a tool yourself will be discussed in this article.
What is a circular saw?
At home and at work the circular saw is necessary for sawing various materials (wood, slate, gypsum plasterboard, soft metal, plywood, etc.). д.). This manual electric tool (as standard) is designed to perform a straight line sawing with a depth of 40 to 140 mm (most models produced by manufacturers allow you to perform a cut at right angles up to 85 mm, but for construction sites there is a line of more powerful equipment). During the operation the operator holds the device firmly in his hands and makes the sawing, moving along the workpiece. No restrictions in terms of workpiece length or width. It is possible to saw at an angle to the workpiece surface.
Saws are available in various capacities. The most economical devices have a capacity of up to 1.2 kW and are designed for sawing workpieces up to 4.5 cm thick. They are well suited for domestic use, for short intervals and are distinguished by their simplicity and unpretentiousness. If cuts of up to 6.5 cm have to be made frequently and for long periods of time, semi-professional tools up to 1.8 kW are needed. Professional saws are available for production tasks with power up to 2.2 kW, which can withstand continuous use and have a cutting capacity of up to 8.5 cm in thickness. In addition, there are tools designed for use in woodworking companies, capable of sawing workpieces up to 14.1 cm thick. Its power is up to 5.5 kW, and weight. up to 100 kg.
Important! For home workshops, devices with a power of about 1 kW are usually sufficient. Before buying the model it is important to consider this point, because overpayment for the saw itself and for the electricity consumed by it, as a rule, is not justified by the need.
Choosing discs for the tool, you need to pay attention to their technical parameters.
- Sharpness angle of the teeth. Soft materials should be sawn with blades that have teeth tilted towards the side of the blade rotation. Working with metal requires models with a negative angle of sharpening.
- Number of teeth. For sawing of different materials it is necessary to choose discs with different quantity of teeth: for soft materials. models with many teeth, for hard ones. with few. For example, for wood, the minimum number of teeth is 24.
The marking of the discs includes data on its diameter and the size of the seating
To use the circular saw for a long period of time, it is important that it does not weigh too much, was ergonomic, and the discs. well sharpened. Holding a machine in your hand for a long time is not easy at all. Operator fatigue can lead to poor sawing quality. That’s why many masters who work with saws practice putting them on the table.
Circular saws are often mounted on a table
The meaning of such a device is to fix the body of the saw under the tabletop so that only the disk for sawing is above the table. Workpiece is moved on the table top and sawed with rotating blade. Such a stationary device greatly facilitates labor and allows continuous work without loss of quality and quickly. Manufacturers offer a large number of models of table-mounted saws. Self-made construction allows not only to save money, but also to get at the disposal of the unit in accordance with their own requirements.
Making a table for a circular saw is not difficult
Building a table with your own hands
Assembly of the tool can be conditionally divided into the work with several of its parts. Its main components are the frame, side extensions, side stops, clamping plates and the base-platform for the saw.
Let’s consider each part in order of importance.
The frame of the product is best made of a metal profile (aluminum or steel), and its cross section is usually chosen from the existing range in the store. Dimensions of frame, as fundamental for the table, are conditioned by free space around, dimensions of cutting element and variety of product (non-movable or mobile).

According to the dimensions of the saw you are considering, in the frame design set aside the level of the bottom line of the potential kerf and the possibility of changing the position of the saw on the bed.
Align and secure the machines
Use screw clamps to fix the extensions to the platform base. Set the machine in place and align it in the middle of the base width. Pressing a long flat bar against the machine‘s standard stop, adjust the position of the machine to align the trailing edge of the bar with the trailing edges of the upper E-shelves. Make sure that the edges of the bar and the shelves are parallel. Now remove the bar and the extensions. Mark the centers of the mounting holes to mount the machine, remove the machine and drill holes in the base plate L. Grind them out from below and secure the machine with countersunk screws, adding washers and nuts.
To position the tables of both machines at the same height, saw two wooden spacers the width of which allows you to make mounting holes for the screws that will fasten the machine with the lower table. Flatten the spacers to a thickness which equals the difference in height between the two tables. Now mount the machine with the low table and make the holes. Secure the machine with screws and insert spacers between the machine and the base.
Preparation of the table
All kinds of such tables can be found in construction stores, from the cheapest to large professional, however, there are situations where it is not possible to buy this product. It is in such cases it is necessary to make a self-made workbench for such a tool.
First of all, in the process of making the table you need to take into account several important points:
- Selecting a convenient free space to install the table;
- mandatory installation of the mount for stationary positioning of the tool;
- The size of the materials to be processed for their successful placement;
- Type and dimensions of the crosscut saw itself, which will be installed on the table.
The next step will be the analysis and implementation of the above items, as it directly determines the success of the table. After studying the instructions for assembling the table, preparing drawings, as well as the necessary building materials, you can safely begin the main part of the entire work.
Assemble the table with our own hands
The assembly of the tool can be conditionally divided into the work with several of its parts. To its basic components include the frame, side extensions, side stops, clamping plates and the base-platform for the saw.
Consider each part in order of importance.
The frame of the product is best made of a metal profile (aluminum or steel), and its section is usually chosen from the existing range in the store. Dimensions of the frame, as fundamental for the table, are conditioned by the free space around, the dimensions of the cutting element and the variety of the product (non-movable or mobile).
According to the dimensions of the saw you are considering, in the design of the frame set aside the level of the bottom line of the potential cutting and the possibility of changing the position of the saw on the bed.
During the interaction with particularly bulky materials in the table provide for the installation of side extensions made of metal, durable plastic sheeting or wood. Once the processing is complete, due to their design, they are lowered to the sides of the unit.
It is possible to make a model not with sliding, but retractable extensions, for example, on the shelf inside the table.
Side thrust pads
To facilitate the milling process, parallel side stops are fixed on the homemade table.
Often they are made of boards and plastic, but we recommend using metal corners with clamping elements as stops.
They are used to fasten the corner pieces to the facing table.
As clamping plates on the table choose a metal profile and equip it with a device for rigid fixation to the surface. The plates are installed as follows: one element is placed under the work surface, and the other is placed above it. Then the bolted connection is tightened, compressing the materials together firmly.
Mounting the saw
Once the metal frame is assembled and the expansions, stops and clamping plates are assembled, the final step can begin. Crosscut saw assembly involves placing it on a platform base and fastening the parts with screws.
The final step is to check the cut-off table for integrity and overall reliability.
Make sure the bed is stationary, the roller base, if any, and any other pivoting mechanism work properly, and the saw has no trouble cutting when plugged in.
The overall reliability of the table is assessed by means of a test run.
Saw table for mitre saw
This technique must have a sturdy base. If it is used in industry there are always stationary bases specially designed for the sliding compound mitre saw. They are very large and not suitable for home use.
If you have decided to buy a mitre saw and install it in your balcony or workshop, the first step is to find a solid base that does not take up much space. There is a huge range of mitre saw bases on the market. In order to purchase did not become a meaningless purchase, it is necessary to be guided by the technical data of the tool.
First you need to find out what you will use it for. Models designed for cutting wooden surfaces do not have the power of those designed to work with metal sheets or products made of shockproof plastic. The size and weight of the unit depend on performance.
Experts recommend choosing the smallest workbenches, but they must be highly durable. The fact that a large-sized base in the entire balcony or half of the workshop will create some discomfort during the operation of the unit.
Many manufacturers of frames provide the ability to change the height of the legs, so that each operator can adjust the table to his height.
Some package crosscut saw models come with a saw blade base. Such tables are ideal because they are designed for a specific tool, its size and weight. In such devices, in addition to the main table, there are additional support stands so that the operator can comfortably work with large products.
Of course, you can buy the base for this product as a set, and separately. The main thing is that the stand and mitre saw must be compatible in weight and dimensions.
You can even make the frame yourself, but the factory version will be much stronger.
The DeWALT DE 7023 is the most striking example of a table. It is collapsible, which is very convenient for transportation in the trunk of the car. An ergonomic handle is provided for transportation purposes. This model can withstand up to 230 kg, and even the longest workpiece can be placed on it when unfolded. The additional table is often referred to as a stand.
The crosscut saws come in a variety of bases. The most primitive costs about 15, but is quite suitable for working with plastic pipes or small wooden products. The cost of industrial models starts from 300.
Circular saw with top table
The top layer is an extra stand that sits above the mitre saw. This addition is very handy and greatly increases the functionality of the tool.
The most striking representatives of trimming saws with the top table are devices of the company Makita. These models are more expensive, have a large number of positive reviews, are highly productive, reliable and dependable.
These products are multifunctional and versatile, and can be used as a circular saw when you need to make a longitudinal cut of the surface. With its versatility, such devices are small-sized, comfortable to use. Cutting does not require great physical strength.
In addition, these units are considered the most traumatic, so all manufacturers pay great attention to operator safety. It has a starter protection from unplanned start-up, a cutter jamming function in emergency situations. The motor is protected from any overloading. If the motor reaches the maximum of its capacity, the unit will simply shut down. Wall saw with top table can cut any surface: wood, plastic or metal.
Such tools are produced by such popular brands all over the world: Bosch, Hitachi, DeWALT and many others. To date, the leader in this niche is the company Makita.
Drawing a circuit
Before you start preparing to build a table for mitre saw with your own hands, you need to decide what functions this tool should perform, and what additional functions may be useful. Thus, the scheme of the device, its drawings and details. And only then drawings of each part are made.
And it’s important to see the big picture of the whole device, not just the picture of each unit.
Preparing to make a table
All kinds of such tables can be found in construction stores, from the cheapest to the largest professional, however, there are situations where it is not possible to buy this product. It is in such cases, it is necessary to make a self-made workbench for such a tool.
First of all, in the process of making a table you need to consider several important points:
- The choice of a convenient free space to install the table;
- mandatory installation of a fixture for stationary placement of tools;
- the size of the materials to be processed for their successful placement;
- The type and dimensions of the very trimming saw, which will be installed on the table.
The next stage will be the analysis and implementation of the above points, as it directly depends on the successful manufacture of the table. After studying the instructions for assembling the table, preparing drawings and the necessary building materials you can safely start the main part of the work.
During this period you should answer the questions that were described above, and then draw a sketch of the product to be constructed.
It is desirable to calculate all the geometric dimensions and attachment nodes, both the elements of the table (legs, work surface, additional elements), and attachment nodes to the base.
Performing the work on the table
The frame can be made out of metal profiles of different cross sections that are available. The geometry of the frame depends on the available space where the equipment will be installed, the size of the bandsaw and the type of installation (stationary or portable).
On the frame it is necessary to provide a place to install the saw, which should correspond to the available (geometric dimensions, the height of the lower mark of the possible kerf, the possibility of changing the spatial location).
Regardless of the size and shape of the frame, it is necessary to provide for side extensions of the table, which can be made of durable plastic, sheet metal or plywood. The presence of lateral expansions of the working surface will facilitate the sawing of long workpieces. If the side expansions are located below the level of the mitre saw surface, it is necessary to install special shelves, on which the workpieces will move.
Side stops will also be useful, thanks to which, after their fixation, it is possible to cut a large number of workpieces to a set size. As Stops you can use angles made of different metals, equipped with clamping elements, thanks to which the Stops are fixed on the work surface, and other elements (bosses, bars, etc.).д.) made of wood or plastic that can be fixed to the work surface of the table.
For the convenience of working with a large number of workpieces, it is necessary to make clamping plates. For this purpose sheet metal or metal profile can be used, which must be equipped with devices, allowing their rigid fixation on the working table. This can be a bolted or other connection, with one of the plates placed under the table surface (lateral extension) and the other over the surface of the workpieces. Compression is accomplished by tightening a bolted or screw connection using nuts or shanks.
- Mounting the mitre saw. When the frame and the additional elements are finished, it is necessary to install the frame on the prepared surface and to hold it firmly there. After that perform the installation of the mitre saw and made additional elements.
- Performance check. After completion of installation of the saw and other elements facilitating work on the given kind of the cutting tool it is necessary to check its working capacity.
If to test the saw it is enough just to plug it into the electric network, then to test the convenience of work performance on the fabricated table, it is necessary to perform a certain work, facing of the prepared blanks. Check that:
- Geometrical dimensions of the table allow performing all kinds of operations that are supposed to be performed on this equipment;
- The table and trimming saw are rigidly mounted on the surface of the floor or other plane;
- The size of the extensions corresponds to the size of the workpieces, they can be easily moved and fixed;
- The alignment of the stops and clamping plates is not obstructed by any unevenness in the work surface of the table or in the frame elements.
Circular saw table is a structural element that allows to work with high productivity and ensures safe execution of operations with different types of materials.

Trimming saws are small devices that are rigidly mounted on workbenches by means of screw fasteners. The workbench frame is cast and maintains the stability of the equipment when processing large workpieces. As part of the stationary wood facing machine, you can find such mandatory elements as the handle, electric motor, cutting head and solid base. If we proceed from the reviews of the owners, this tool requires certain skills to effectively solve the tasks that arise, and also needs careful maintenance.
Different types of saws vary in price, related to the objectives of the model and the prominence of the manufacturer. The most famous brands:
The crosscut type includes the following parts:
The collector motor does not require regular tracking and lubrication of parts, while the induction motor stands out for its long and quiet operation. There are variants where the motor is rear-mounted, which makes for much better visibility when working by hand.
The motor works by means of a mechanism that transmits the rotation through a belt or toothed wheel. In the first option, there is less noise and no shaking of the cutter, and the second option does not allow the saw to slip when cutting in case of strong pressure.
Advantages and disadvantages of a homemade device
Like any other device, a homemade mitre saw, derived from a manual circular saw, has its own characteristics and features. Some of them are positive in nature, while the other part is colored negatively. Either way, both features must be considered.
on how to make a crosscut saw from a circular saw, see the video below.
Machine with pendulum motor suspension
Those who can boast the ability to work with metal, you can advise to make a circular saw with a pendulum motor. The main feature of the device consists in the fact that the motor, shaft and cutting disk are installed in one common frame. It is hinged to the bed on one side, the other is held by a screw with adjustable height. By changing the length of the screw, you can regulate the height of the disc out of the tabletop.
This system allows you to adjust the height of the cut, as well as the use of discs of different diameters. And if you use the feeler gauge on the worktop instead of the adjustment screw, you have a simple copying machine. The stylus will allow you to adjust the depth of the cut according to a certain template. This fairly simple rework will turn a simple circular saw into a real woodworking machine. With such a device you can not only cut the board into the necessary blanks, but also to make precise cuts, make various selections.
End trimming saws varieties
There are several types of mitre saws (also popularly called “trimmers”). Let us see what they are.
The base of such a saw is the frame. A table is attached to the bed, which must have a swivel mechanism with a ruler. It is this mechanism that allows the sawing process to be performed at a certain angle, adjusting it to the specific individual needs of each user. And this angle can be changed by moving the working table directly in relation to the bed.
As for the saw, it is fixed in this device by a lever and spring-loaded by means of a pivot. Thanks to the pendulum, which gave its name to this type of mitre saw, the saw moves upward or downward.
When using a combination saw, the cutting angle can be changed in 2 directions. Like its predecessor, it has an additional joint. In order to change the cutting angle, it must be adjusted and pulled to the side that is opposite to where the actuator is installed.
With a pull-through
This device is considered the most universal, because the saw can be moved not only around the axis, but also along the kerf in a straight line.
