Train Station? David, you heathen!
My Chipmaster has a 3hp motor and drives the Spindle via a Kopp Variator, a Matrix multi-plate Clutch and V Belts. The Clutch is surprisingly small. It runs up to 3000 rpm. It doesn't care what speed it's set at when you start it up, or what's in the Chuck. I bet Col's old Colchester was even more brutal.
Myford used slipping belts for many a long year, particularly on the Tri-leva, so it must be possible to get it to work. It's mainly the lack of space that's the problem I suspect.
Col, can't you mount the Inverter controls remotely? Most of the ones I've seen allow that. Essentially you just need a couple of Switches and a Pot in a box.
