Out of all the discs I have tried, the blue ones from Vince seem to best deal for price and durability, and I prefer the over sized discs. I can get several bowls out of one set of discs. I do prefer an angle drill to a right angle drill, and use the Milwaukee angle drills. There are cheap ones available, but I prefer one that is worth having rebuilt from time to time rather than toss it away. Slow sanding speeds on both lathe and drill. It is a traction thing. Too fast and you send dust everywhere, but don't move too far. Slower speeds give your abrasives time to dig in and cut, and don't generate heat. I did try a battery version of an angle drill, and the battery didn't last for one bowl. I think the plug in variety is far better.
