Just wondering if anyone in the group has any experience with or
thoughts on using an open motor for a belt sander. This will be a
home-brew sander, probably belt-driven, so I may be able to protect
the motor to some extent, but not completely. Should I anticipate a
quick death for an open motor in this application, or could I expect
just a slightly shortened life span? Would a TEFC motor be worth the
extra bucks?

Thanks.
Bert
