I use a harbor freight buffer and than have it on a reostat as well Definitely might have to give this a try, thanks for the suggestion. I'm still getting the hang of the sander but seems to work well. I got quite a few tips from a guy at the Tyson Wells show that really helped. I used the HS sanders in our clubs shop a bit, and had to instruct new users as well. Until they were replaced with magnetic large wet laps bandaids were definitely a consumable in that shop. In addition to the safety issues that should be obvious: *A well tuned and aligned slab saw with a good quality blade will save you lots of time on the sander, I could start at 220 grit most of the time when I used one if it was my own slabs. Any saw nubbins or sharp edges should be broken o ground off/chamfered with a wet diamond wheel as they will shred the sandpaper and turn it into a 100mph projectile. *Sand in one direction with each grit as much as possible, then turn 90 degrees when switching grits. Dust will reveal the scratches from the previous grit until they're done. *if there are pockets in the rock, scrape a piece of bar soap across them to fill the void with soap shavings so cleaning the dust out will be easy. *treat the rotating edge as if it was a razor blade, because it is, *keep several pieces on the bench and rotate through them on each grit to allow time for them to cool without using water if possible. *on the finest grit, run a 2nd pass with a very light pressure. A mostly worn fine disc can also help. *DO NOT bend down to attempt to look at what you're doing and bring your eyes, face, even your throat in line with the spinning disc. I made a step for shorter members to stand on when operating it.
