Re-furbishing/updating my old Craftsman 4-1/8" jointer (all cast iron). The old motor is showing signs of wear (shaft play). I have a Craftsman 1-hp. motor in good shape that I can use in place of the old one. Here's the rub:
The jointer originally came with a 1/3hp 1750 RPM motor. The V-belt pulley system was set up to run the cutters at 4500 RPM. My new motor runs at 3450 RPM. Using a 4" drive pulley and a 2-1/2" driven pulley, the cutter is spinning at a cool 5520 RPM. Is this too fast? Is it in any way "dangerous" to life and limb? I always heard that the more cuts per second results in a smoother finish cut. Does this apply, or is that just for routers?
