Quick question. Now that I’ve won my battle with Monkeypox, I’m on to fixing up this old radial arm drill press. Rockwell/delta 11-280 to be exact. Motor works wonderfully and she’s all apart. Should I soak rusty parts in vinegar and then grease everything involved in the drivetrain? If I paint it red, will it drill faster? How the hell does one change the speeds on such a tool? (It’s the oldest version- not the one post 1974) Thanks for the help, ridicule, whatevs. 0/

Pretty much. The common dimmer/fan controller is a rheostat. I needed a way to control the speed of a cheap blow up mattress inflator for a small smelter that I made. Used it for many other applications.
