I'm working on some small patterns and having a lot of trouble with the wood chipping out. My spindle is running at 30,000 rpm and I'm using new carbide bits. I've tried some MDF, Basswood, and something else I think was elm, it was terrible. Any suggestions? I'm using F-Engrave and the letters are very small. I guess I need a Laser.
What kind of wood carves best? Should I coat it with some kind of sealer?
This is like a coaster, about 4" diameter.
