I obtained a power feeder in a package deal a couple years ago. Recently I have set it up on my shaper and tried it out. MY problem is the wheels are glazed over and dont grip the piece of 2x4 that I am learning with. Can I sand the wheels ? My feeder is one h.p. three wheel type. It is a king Canada brand. Made in Taiwan. Where would one get new wheels and what type of compound should I get ? My use would be solid wood . any advice is welcome,thanks Mike
