I've got a 4 x 6 Shop Fox saw. I've read the discussion on this saw being the same as Jet and Wilton or whoever, but this is not my beef. My saw will not keep the blade on. There is some slack in the bearing housing on the drive wheel that lets the pullley tilt some toward the idle pulley, but it still rides 3/4 on the pulley. Sometimes it will stay on for a while and sometimes it pops off after about 10 seconds. I think all of these saws have alot in common (if not being exactly the same) and thought someone out there might have had this happen to them or know how to fix it.
