    BAZMAK-Diary of a Myford ML7 lathe restoration

    I finally made chips by finish machining the adaptor plate in situ. Shame to get the lathe dirty Its a beautiful machine so smooth and quiet. When i did a heavy cut it did bog down so for future ref the 1/2hp motor and VFD may not be adequate.May fit new 1hp single phase later with f/rev switch...

    BAZMAK-Diary of a Myford ML7 lathe restoration

    Thanks Baron,your simple answer made sense.Just picked it up and refitted to the lathe Seems to have sorted it all.More speed and torque.Bit more tidying up before testing under load. First job is to make an M42.5x2 male spindle nose plug gauge so i can make an adaptor plate to fit all my 4"...

    BAZMAK-Diary of a Myford ML7 lathe restoration

    Thanks guys. I have taken the motor and VFD to a local motor rewinders and he has said he can rewire to delta and the conns have to be picked up inside the casing. Nice asian guy with heavy accent when combined with mine made conversing difficult.However with additional sign language he...

I was under the misconception that the digital readout was for the rpm but now i realise its only the frequency. I really need to get a rev counter at...
