A while ago I posted a thread on how to make sanding drums for the 1/2" rotary tool sanding mandrel. I have since refined my method of creating them to produce more at once and constructing them to be less prone to catching and edge or fraying. The instructions to do so were given in a very abridged form at the end of the thread, but, I figured I'd write another tutorial for those who want to know :)
Anyway here is the tutorial. Enjoy :D
