I made a simple belt sander attachment for dremel rotary tool.
Material i used 3mm thick steel and wheels from a skateboard.
Structure is very simple and Its made from 5 pieces, connected together with nuts and screws.
Sander is powered with a Dremel 4000 rotary tool wich can be removed after use.
Edit: My original video disappeared from YouTube.
This one is re-made, but misses some making footage.
But, it has some improvements and a closer look for the buil itself.
"Plans with the main measures" measures are in millimeters. One inch is 25.4 millimeters.
Later i made a little changes to it and now its an attachment in my rotary tool lathe construction.
Modified a splash guard from a dremel tool to hold the rotary tool, so its very quick and easy to attach.
This can be seen from these videos:
