Using a 24 inch Powermatic dual drum sander I’m typically experiencing scoring/burning on one or both paper rolls after a relatively small number of passes – say between 6 and 12, a rate that I know is way too high. This is happening with dry cherry and mesquite without pitch problems and despite shallow cuts (about a quarter turn per cut). I’ve checked set up, paper grits and adjustments carefully against recommendations.
Does anyone have suggestions on what to do with a scored/burned roll except to replace it? Wire or brush cleaning doesn’t seem to do much good – once the score is there it persists and gets worse, marring the wood. Should I try to get rid of the score on the paper by, say, using a chisel cut the score area down to the paper base? Is there a solvent that might help?
I’d welcome tips on ways to avoid scoring/burning on the paper roll in the first place.
The unit’s great when it works well but I’m buring through too many sanding rolls.
