Well start listin!

I have two dremels... a "high power version" and a "weak @$$" version... i have everything from grinding bits, to hardened tungsteon carbide grinders (for hardened steel) to sanders, polishing bits, diamond-tip jewelers drillbits, and a bunch of others... any in particular that i'd need?
I still haven't committed to this project yet, but i'm trying to scope it out and see what all is involved. I'm perfectly ok with buying a new sleeve when I mess up big time... Thats how you learn!
