I've got an old belt table sander. I rebuilt the top and just got a new
belt it is 6" * 25" but found the motor is bad. The old one has no labels
or markings to know what speed or brand it is. This sander was from a
cabinet shop that was active in the 30's up until mid 70's.
I've got a couple newer ones but ? is what speed should th belt sander be
run at. I can change the pulleys if needed but currently the motor I had
in mind is a 1/3hp 1724 rpm.
