Hi I have a scanned copy of the Bridgeport series 1 manual. I don’t know if you have a copy but if you don’t I can send you it on CD.
I also have the wiring diagram for a Micron WF31C CNC mill and the wiring diagram of a ONA spark erode on the same CD. If you want them where do I send them to. I sent a message to Dave Clark for the library and haven't heard anything.
