I don't know which way my motor spins. Sitting on the bench or in my vise, arbor to the left, it spins away from me. Of course if I reverse the motor, it spins the other way.
You do have to wire in a toggle switch, two wires, pretty simple but I had to trim the wire cover to run the heavy power wire inside the cover (used an old grounded appliance pigtail found at a yardsale). I had to drill a hole in the housing for the toggle switch, that took a little creativity.
Here's my motor and mounted on the vise. One pix shows my toggle switch and wire. This motor has no capacitor to "soft start" the motor and I have to have it plugged into an outlet with a HD 20 amp fuse. My wall sockets on the work bench throw the senstive GFI.(should have upgraded this whole garage to higher amp service when I built the house). I took the nut off the Jestco arbor and put on a wing nut I trimmed down (so it doesn't inadvertently hit my pipes..) so I could swap pads without a tool. The nut just has to be snug. The Beall system just spins on. I don't know how easy it is to swap buffs with the Beall spin-on arbor, so I went this route. Member "SmokinDawg" makes and sells an identical system to the Beall with all the attachements, etc for a better price, you might want to contact him. Hope that helps.
