3. Too much sanding force on the
work piece.
4. Work piece held still against the
belt-disc for too long.
1. Use a finer-grit sanding acces-
sory.
2. Sand with the grain of the wood.
3. Reduce pressure on workpiece
while sanding.
4. Keep workpiece moving while
sanding on the sanding acces-
sory.
Sanding surface clogs
quickly.
1. Too much pressure against belt/
disc.
2. Sanding softwood.
1. Reduce pressure on workpiece
while sanding.
2. Use different stock, different
sanding accessories, or accept
that this will happen and plan on
cleaning or replacing belts/discs
frequently.

fine.
