You can make a very convenient manual belt sander from an angle grinder with your own hands. With the help of such a tool it is good to sharpen an ax, knives, etc. Treat the surface at any angle, giving it a flat plane. In general, anyone who works with iron or wood will appreciate this mini machine.
Sharpening the cutting edge of the ax:
With this sharpening, the corner will not float away.
How to make a belt sander from an angle grinder
The mount for the angle grinder will be made from a piece of thick steel, about 10 mm thick. We drill a hole for the neck of the angle grinder.
We cut a wide slot.
Using a grinder we cut off the fastening.
Next, we clean and polish so that everything looks beautiful and safe.
We drill a hole from the legs of the clamping device.
Then cut a thread on the wide side.
As a result, this mount can easily be put on the angle grinder and clamped so that everything is held tightly.
Let's try it on.
Now you need to make a roller that will rotate the sandpaper tape. We take chipboard and use large diameter bits to cut out round pieces. To obtain a wide roller, we glue the round pieces together.
Then use a feather drill to drill a hole in all of them at once.
Then we clamp it in a vice and use a triangular file to make an internal hole for the hexagon.
Like this.
We take a wide nut and make notches on the planes with a file.
They are needed to help the nut stay in the wood better.
We dilute two-component epoxy-based glue and glue the notched nut into the wooden roller.
After the glue has dried, clamp the roller into the lathe.
We sew under the ellipse. This is necessary so that the tape does not fly off. Then sand it with sandpaper until smooth.
It came to the second video. It is made of three bearings pressed onto the main line.
Let's make two such ears.
We put it on the edges of the protruding shaft.
Let's weld the plate. The result was a U-shaped part holding the roller.
To prevent the shaft from flying out, we fix it by welding
Now let's make the frame. You will need two steel pipes of different diameters so that one fits into the other.
A flat overlay is welded onto a larger diameter pipe. It is needed in order to press on the tape while sanding.
We weld a roller of bearings to a thin pipe.
We take a ring of sandpaper (sold in hardware stores), insert the pipe into the pipe and estimate the approximate size of the entire device.
We saw off the long ends of the pipes. We make a wide groove in a thin pipe, and a hole in a thick pipe.
We weld a nut to the hole.
To the ring mount - a section from the pipe.
We weld the rod with the fastening.
We paint with spray paint.
After drying, insert the pipe into the pipe. We fix it with a bolt.
We put it on the grinder and also fix it with a bolt.
All that remains is to put on a strip of sandpaper and the hand-held belt sander is ready.
Works great.
If the belt oscillates, tighten it. But there is no need to exert a strong tension.In general, at high speeds the tape behaves stably.
