I'm currently in the process of rebuilding a 6" Jointer that I purchased off of e-bay. This is an old Pryor Jointer with a 4 blade cutterhead, and a 54" bed. The old motor is not in very good shape and the darn thing has been painted over so as not to be able to tell the H/P or the RPM. I'm thinking that 3/4 hp should be fine. What says thee?
