+1 to the hand saving. Been testing it out on 80 grit an a old rusty Rambo knife I found in a tackle box. Works the bomb indeed at 80 grit.
Reduced my rpm and generated metal, but no heat. Very cool option. And reversing to fluff the wheel is good thinking. Didnt think I would use the reverse much but it was in the original circuit I built so wth.
Just picked up 4 more buffs and 180, and 300 compound so I can have 2 wheels loaded with 80 and one each at the higher steps..
Next I need to see if I can restore my very old lathe.. Feel some word projects growing in the wintertime..
