Anchors from burnt-out small electric motors can be used to make grinding drums. Their shaft will serve as a shank for installation in a drill, and the core will serve as a basis for gluing sandpaper. Let's look at how to do this.
Materials:
- anchors with electric motors;
- universal glue;
- sandpaper.
Manufacturing process of grinding drums
It is necessary to disassemble unnecessary motors and remove the anchors.
Next, you need to remove the bearings from them, and cut off their shaft on one side flush with the core.
The remaining part of each shaft is clamped in turn in the drill. In the rotation mode, the edges and the cut end are sanded using emery.
A strip of sandpaper is cut to the width of each anchor. The core is lubricated with glue, and it is glued with overlapping edges. They are then cut to fit flush.
Before the glue dries, elastic bands are pulled on top, thread is wound, or nylon ties are placed.
Using this principle, you can make many sanding drums with different paper grains. You can also glue a sponge or felt to create a polishing attachment.
Next we use it for grinding, cleaning, sharpening.
You can always take these drums with you and use them wherever it is convenient.
