Finally got my rotary converter running. Got a control box from Ebay and put on my motor. Had to get a 3ph receptacle for it. Local electrical supply wanted $65 for a bare box mount . Got one from Ebay for $20. Good news is the mill runs fine and the bad news is the power feed on the quill does not work. Can't even feel the transmission engage. This is a Webb Champ series. Supposed to be a Bridgeport clone. Anyone have any ideas? There are pictures of it farther down in this forum.
