How to make a circular saw from a grinder? Step-by-step instructions for beginners

A circular grinder is made independently using available tools and materials. You don’t even need a welding machine for this - you can make a wooden table and install a bracket with a grinder. Then it is gradually raised (with the tool turned on) and a gap is created in the tabletop. This will become the main working surface. How to make such a device in 1-2 hours is described step by step in this article.

Materials and tools

A DIY circular grinder made from an angle grinder has quite a few advantages. The main advantage is significant savings due to the fact that you do not need to purchase additional tools. At the same time, you can make it yourself, and it won’t take much time.

To correctly understand how to make a circular grinder from a grinder, you need to prepare available tools and materials:

• an angle grinder itself or an angle grinder;
• drill - it is used to form holes into which fasteners will be inserted to fix the brackets;
• several chipboards;
• clamp and other fasteners;
• a special disk designed for cutting wood;
• construction tape;
• pencil.

A grinder saw is made on the basis of the corresponding tool. Moreover, it must have sufficient power, because the quality of sawing depends on this parameter.Another point - the grinder should be medium or large in size. If it is too small, such a device can only work with thin materials.

It is also worth considering that a circular saw made from an angle grinder is equipped with its own disc. It will not be possible to use the nozzle from a circular saw, since it does not match the size of the mounting hole. In addition, protrusions in the form of teeth should be located along the outer diameter. Their number varies depending on the specific model.

Step-by-step instruction

You can make a saw from a grinder with your own hands in literally 2 hours. The main task is to make a working surface in the form of a small table with a recess (slot), and also to fix the tool on a pre-installed bracket. The sequence of actions is as follows:

1. On the chipboard, make markings for 4 legs and the central part.
2. Drill 4 holes with a drill for the legs.
3. Drill a hole in the center, install a bolt and nut and trace it clearly along the contour. Using a chisel, expand the hole along the intended boundaries.
4. Insert the nut and bolt into it and check how it tightens.
5. Attach the chipboard to the larger slab, mark and drill holes.
6. Likewise with the second plate.
7. To make a circular saw from a grinder with your own hands reliable, you need to make 4 legs from timber. It is sawn into equal parts and mounted at the corners of the workpiece.
8. The screws are screwed in with a drill and you get a small table.
9. The other plate is fixed with metal pins, as shown in the photo.
10. A second slab is placed on top.
11. Take the workpiece made at the first stage (it will be located in the middle of the table) and screw the bracket.
12. Now comes the main stage of the instructions on how to make a circular grinder with your own hands. Using a clamp, secure the tool, as shown in the photo.
13. The bracket is finally fixed on all sides.
14. Fix the sawing disc.
15. The top surface is finally installed.
16. Mount a wooden handle with a wheel to adjust the height of the bracket.
17. Turn on the grinder and, gradually raising the bracket, drill a gap.
18. The result is a miter saw made from a grinder.

How to use the tool correctly

If you make the device correctly, in terms of quality and reliability of design it will be no worse than a store-bought one. But at the same time you need to understand how to use it correctly. There are no specific rules, in general they are simple and intuitive:

1. Sawing can begin when the crosscut angle grinder with your own hands reaches the required power, that is, the rotation speed.
2. One cycle can be operated continuously for a maximum of 20 minutes to protect the engine from overheating.
3. If the speed drops during sawing, the wooden part must be removed immediately to determine the cause. Otherwise, you can ruin the entire mechanism.
4. If, on the contrary, the number of revolutions is too high (from 10,000), you need to reduce the voltage by rotating the spindle. Otherwise, wood smoke may occur.

If you wish, you can make a circular saw from a grinder even without special experience. This is a fairly simple and at the same time very useful device. Moreover, it will cost much less than a store-bought tool. Suitable for most household tasks.
