Sometimes a belt sander is badly needed on the farm. This is an extremely useful tool thanks to which you can sharpen or grind any materials. You can make this machine yourself from an ordinary grinder. Such a tool is usually present in every home workshop, and the cost of a small grinder is quite low.

Peculiarities

What you need to know about a belt sander before making it yourself? There are several important criteria that affect the performance and quality of the machine. The main one is power. After all, it is the main component of a homemade car. Devices with high power and high speed are suitable for intensive cleaning of any materials. But the medium speed is useful for surface grinding. A universal option will be considered an angle grinder with a speed regulator. In this case, you can independently adjust the rotation speed depending on the degree of processing.

You should also consider the width of the future sanding belt . Depending on it, the dimensions of the driving and driven wheels of the home-made apparatus should be selected. Many tapes are 100 mm wide, but 75 mm wide tapes will also fit for small household needs. And don't forget about safety. This also applies to the manufacture and use of the device. Welding will be used in the manufacture. Therefore, it is worth working strictly in a protective mask.

It is recommended not to keep any flammable objects or flammable liquids nearby. The self-made device itself operates from the mains. Therefore, it is necessary to avoid high levels of moisture and pay attention to the insulation of the wires.

What is necessary?

So, before proceeding with the manufacture of a belt sander from a grinder, it is necessary to prepare all the constituent materials and tools. For this you will need:

• the grinder itself, which is the basis of the future apparatus;
• bolts and nuts;
• Sheet steel;
• springs;
• square tubes.

Among the tools you will need:

• a vice, on which most of the operations for the manufacture of a grinder will be carried out;
• drill;
• a hammer;
• welding;
• set of wrenches;
• roulette.

How to do it?

When all the constituent parts are prepared, you can start directly to work. First you need to make a bracket for the grinder. It serves to securely hold the tool. The bracket is made of steel plates. They must be firmly clamped in a vice and bent in the shape of the grinder. Then the resulting sheets are welded to each other. In addition, adjusting bolts can be installed on the bracket, which will allow you to change the angle of the tool.

Then you can start making the driven wheels . In total, there are two of them in the design. This will require bearings and bolts. The bearings are bolted and secured with a nut. On top of it all, you can attach a rubber hose for smoothness. Next, you need to make a work plane. The product will rely on it when working on a future belt sander. The working surface is made of steel plates that are welded together.

It is also necessary to well clean the seams from welding. Further, at the ends of the plane, holes are drilled in which the driven wheels are installed.

It is worth preparing the foundation for the entire structure. For her, you need a square pipe. It is necessary to drill holes in the pipe on which the bracket and grinder are attached. It is recommended to secure them with bolts and nuts. Then the work plane is attached. Everything is carefully welded. Next, you need to make the main drive wheel. A short rubber coated metal tube can be used for it. Such a pipe is firmly attached to the angle grinder shaft with a nut. Then a spring must be fixed between the base and the bracket, which will tighten the belt of the sanding belt.

Then you can install the sanding belt itself on the device . This device should be securely fixed at a convenient work place and you can start testing. It is imperative to tighten the belt so that it is centered on the drive and driven wheels.

It is also recommended to take proper care of the machine. With prolonged use, dust can accumulate on the belt and on the working parts, leading to early wear. Even specialized grinders with dust collectors are not immune to this problem. Therefore, all working parts must be accessible for cleaning them from the remnants of processed materials.

How to choose a ribbon?

Sanding belt is one of the main components of a homemade sander. The main indicator of the quality of a sanding belt is the size of the abrasive grains. They are responsible for the quality of the grinding of the material. Belts can be coarse, medium and fine. By themselves, abrasive grains are artificial minerals with a high degree of hardness. Also, the tape material should not be overly rigid. Such tapes are often prone to breakage. You can also use rolls of regular sandpaper for your DIY sander.

So, you can make a belt sander from a grinder without problems and fairly quickly with your own hands. And given the cost of ready-made grinding machines, making it independently is a rather relevant and reasonable solution.
