Richard:

Not meaning to confuse you with differences of approach, but here's what I
did in this regard. The drill-motor is a 400 Hz. 3-phase "aircraft instrument
motor" with some serious machine-work on it so I had a collet on the "shaft
end". I built the 400 Hz. generator (95 W.) myself. Not really difficult.
The CNC control is no longer done by the PET you see in the photo, but by a
typical PC (only, since uses only GWBASIC, an old '386 works fine!). Jan
