Mike, I've had a bad run lately of woods clogging up my drum sander. I did some research and found a solution that worked pretty good the other day but it's a hassle. If you wipe the wood down good with acetone and let it dry quickly before each pass it won't clog up the sanding drum. I was using 60 grit doing light passes. If anyone else has any tips for dealing with oily woods I'm open to trying them out.
