Has anyone cut a keyway in a steel pulley without a broach? I was thinking about ways to do it, like using a blank cutter from a lathe and using a press taking small cuts or maybe a drill press in off position as a press taking small cuts. I have done one where the center of my tractor rear drive pulley wore out a few years ago and could not find one anywhere, odd size, so I found a piece of pipe or tubing with the right I.D. and cut a slit in it for the key and drilled out the pulley hub to the right O.D., then tact welded it in. It is still working fine. I also cut a woodruf key from a thick washer. I did not want to finish cutting grass with a push mower, lazzy I guess. Does anybody have any new or old ideas on how to do this?
