    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...

    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...

    Well the VFD arrived today.Just a cheap chinese one,just to get me started I mounted it to the side of the cabinet for now and had a quick play. 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...
