I use my die grinder{air run type not a dremal dremals are crap}
I use pre made sand paper rolls. I picked up 4 large boxes on ebay long time ago of #80-#220 and some finner grit would have to look at the boxes, The same ones you would port an aluim head with.
I think i still have 3-400 hundered left.
Once the 80 is done i use a candle, hit the hot roll on the wax and then use it it holds the grit and keep it from eatting the paper roll up
Then use the black emery on cone shaped buffs and the white rouge
