When you have your own house or cottage, then a static circular saw will be an excellent assistant for you. With its help, you can quickly and efficiently carry out complex work on cutting various products. Such a tool can be purchased if the budget allows. And you can create it yourself. It is also important to have the necessary devices for him.
A circular saw. The concept
A circular saw is a special electric tool that allows you to quickly and smoothly saw wood products, plywood, laminate and various boards.
There are household and professional models. The former can function with pauses. Their engine needs breaks of 15-20 minutes. They do not withstand a significant load.
The second has more powerful engines. They can work intensively for a very long time. Therefore, they are usually involved in production.
For use in personal households, household modifications are used. And keeping professional versions is unprofitable.
The level of work and their types are determined by the bed of this tool.
About bed elements
Devices for a circular saw are various. The main one is the bed. If the saw power is insignificant (no more than 1.2 kW), it is easy to build such a stand on your own. Its length is affected by the length of the material going to cut.
The Bosch electric drill is suitable for the drive; its parameter is 0.85 kW. It is mounted under the stove with a special bracket.
The accuracy and evenness of the cut is better when the workpiece rests entirely on the table surface. And if the table will have too large parameters, it will fill the entire working area. Here you need the average value. Height is selected according to its height, so that it is more convenient to work.
Materials and tools
Bakelite plywood with a minimum density of 5 cm is bought for the table.
In addition to it, you will need:
- Board 5 x 10 cm.
- Bars 5 x 5 cm.
- Clamps.
- Set of screws.
- Glue and varnishes.
- Manual circular.
- Electric jigsaw.
- Manual type milling cutter.
- Drill.
Make a table
When you need to assemble accessories for a circular saw with your own hands, the first thing is to create a frame. It consists of a base and countertops.
The design of the second element is affected by the structure of the fastener of the working disk.
The process of creating a key tool for a circular saw goes through several stages. They are outlined below:
- From the plywood sheet, a blank of a functional table (countertop) is created. Work is underway on the selected parameters. On a sheet with a pencil on a ruler markings are put. The sheet is sawn with a jigsaw. Edges are milled. The created workpiece is ground.
- On the bottom plane of the countertop, marks for the saw are indicated. The finished workpiece is turned over. A saw is placed on the proposed site in which there is no disc. Outsole parameters are indicated.
- Using a milling cutter, an opening of 8-10 mm is created in this material according to the designations of the landing section.
- Trying a saw. If necessary, the parameters are adjusted. Then indicate the areas of its fasteners and a slot for its disk. If the material will be sawn at different angles, this must be taken into account when designating the slot. She will receive a section in the form of a trapezoid. The top will rush down.
- Stiffeners are indicated with a pencil. Legs will join them later.
- Work on stiffeners. To create them, boards of 5 x 10 cm are used. They are placed around the perimeter at a distance of 7-10 cm from the extreme side of the table. The board is applied to the countertop. Circled on both sides. The ruler marks its main line. It marks the position of the screws. They are as follows: 5 cm - from the extreme side of each of the existing ribs. In this case, a distance of 15-20 cm along the entire length of the rib is observed. Through holes are drilled according to the created markup.
- Longitudinal stiffeners are arranged. To do this, boards are marked and sawn. They stick to the countertop. Compressed with clamps.
- Marking of lateral stiffeners is done. The boards are sawn and glued, as in paragraph 7.
- The clamps are held. The design is stretched using self-tapping screws along the created holes that are pre-drilled from the outside. So the hats of the screws completely drown in the countertop.
- Stiffeners are pulled together by two 5 cm screws. Pulling is on all sides. Clamps are removed. It turns a countertop.
Making legs
Assembling a complete tool for a circular saw is not limited to these stages.
For the legs you need a board 5 x 10 cm. Their height is 1-1.2 m.
The board is cut along the longitudinal vector. In this case, a slight angle is observed on one side.
Feet are trying on the countertop. During installation, they should be a little in disguise.
They are mounted outside the stiffeners. The method of attachment is bolted. To enhance their stability, you will need screeds. They need a 5 x 5 cm block.
The hand saw is placed in the previously created groove from the lower zone of the countertop. The sole is fixed with bolts. The disc is put in the slot.
The table is varnished in 3-4 layers. This is a measure against moisture.
On and off
The assembly of the main tool for the circular saw is almost complete. It remains to establish the launch and shutdown of the tool. The simplest solution here is that the start key is pulled together by a wire, and the saw is turned off by the power cord.
A more complicated method is to shunt this key. And the control buttons are displayed on the outer plane of the front stiffener.
Question of facing
The tool for a circular saw for cutting is especially useful when you need high-quality transverse cuts.
Such a device can be made independently by the proposed technology:
- The base is gathering. Two parallel strips 2.5 x 5 cm are glued to the upper plywood zone with parameters 1.8 x 30 x 122 cm. They are attracted by screws.
- Corners are attached to them (their material is aluminum). The fastening method is countersunk screws. The angle of the fastener is 90 degrees. Fastening takes place in parallel at a distance identical to the width of the base of the saw.
- The tool is adjusted to file the planks to a shallow depth at the base.
- The device is fixed with clamps. A workpiece is placed at the corners. The cut is done.
If the saw does not go well, this area can be coated with paraffin, but with a thin layer.
Question on long cuts
Creating a device for a hand circular saw, which will help to make long cuts, is relevant for many home craftsmen. It greatly simplifies the work.
Its easy to do. Fiberboard is taken. A sample is cut from this material. It is identical to the distance from the extreme side of the base of the tool to the extreme part of the disk from the inside.
When cutting, you must rely on the length of the base of the tool.
The edge of the sample is combined with the designation of cut on the workpiece. A straight part is applied to the second side. This is the guide. It is fixed with a clamp.
In the second layout, this operation is duplicated, but on the opposite side of the blank.
To create a template, it is optimal to use a router or a jigsaw.
The solution to the issue of chips
If you get chips from the disk, you can’t do without the following equipment for a hand-made circular saw, assembled with your own hands.
Technology:
- An element of hardboard is cut out. Its density is 6 mm. When cutting, you need to focus on the width of the base of the tool.
- The disc is retracted. The defensive cover rises. The result of paragraph 1 is attached to the base with double-sided tape. After this, the saw starts. The disk fits smoothly into the hardboard. It turns out zero clearance in the work.
Saw should be with little impact on the established basis.
Tenoning device
The tenoning device for a circular saw increases the efficiency and accuracy of the production of tenon-groove joints. They participate in the assembly of various carpentry products: furniture, doors, frames, frames, etc.
Thanks to such a device:
- Workpieces are arranged without distortions.
- Operations are repeated scrupulously.
- The final result is of high quality.
Such a device can be purchased or made by your own efforts. Experts recommend the first option. This is a full guarantee of achieving excellent results.
Often buy such models: Felisatti FTJ and Festool VS 600 GE.
This is a reliable and proven technique.
Sharpening issue
The circular saw needs to be sharpened when the following symptoms appear:
- It becomes harder to work with.
- Black traces remain from it on the material.
- There is a nasty smell and smoke.
Ideally, it should be sharpened on a professional machine. If not, you will need a tool for sharpening circular saws.
Necessary set for work:
- Vise.
- File with a flat functional side.
- Timber.
Work should be done with gloves.
Grinding Stages:
- Hard disk fixation. It is removed from the saw and fastened in a vice. In this case, wooden dies are used. You can leave it in a saw, but stick a block between its teeth. The bar rests on some surface.
- The initial clove is marked.
- The back part of the tooth is processed with a file. They need to spend several times on it. The effort is small. Each clove is sharpened in turn. The movements are uniform, the number of file runs is the same.
- The front parts of the teeth are processed. The principle is the same.
The tips of the teeth should be perpendicular to the surface of the disc.
Then all the teeth are inspected for defects. Edges should not shine. If so, they are smoothly filed.
After that, the disk is checked in action. It is placed in a saw. She turns on. A test bar is used. If you drank light, smooth and quiet, then the sharpening is of high quality.
Otherwise, you need to check the height of the teeth. To align them, bring the marker to the working edge. Then the disk should go all the way to the other side from rotation. Mark remains on all teeth. On it you can level their height. The tallest teeth are carefully filed.
Conclusion
A circular saw is a very useful tool in the household. But it becomes even more effective if it is provided with the necessary devices.
