I bought a 10"/20" Powermatic drum sander from Woodcraft last year. It
seems to have an alignment problem: when I sand a board that's about 8"
wide, it comes out slighly thicker on one edge than the other - about
..010" thicker on the inboard side (the side closest to the motor). How
do I adjust this thing so that the spacing between the drum and the bed
underneath is uniform all the way across?

Thanks!

Powermatic? Didn't know they made one. With the Performax, one
loosens the bolts which hold the head to the frame and tilt the head.
A bit of a fussy adjustment but explained fully in the manual. If
your machine is a Powermatic I suspect it came with a manual too.

If you ever intend to use the sander for work wider than 10", it is
not a bad idea to have the inboard drum end slightly higher as that
prevents a trough at the outboard end of the work.

Sorry. It is a Performax. I was using it to sand some thin figured
mahogany earlier this evening, and saw those bolts on the top end of the
frame. Unfortunately, I'm not sure what I did with the manual. :-(

Thanks for the help!
