My take on the motor frame etc was that it was more work then required. My
first motor was a small 1750 rpm induction motor and I put step pulleys on
both the motor and spindle. I had 4 speeds by changing belt positions. Now
I use one of those surplus 2hp (1.5 is more like it) DC treadmill motors
(remember that flurry of RCM purchasing a few years back ?), which works
really well. Both of these motors required a simple mount that I built to
fit. And that's my advice here, get a motor (DC with speed control is
ideal) and then worry about the frame/mount/whatever.

I've finished chapter VI of Gingery's book, The Metal Lathe. So far in the
book, I have been able to visualize details of the construction and to
answer
most of my own questions about it. I do have a few questions about Ch.VI,
though, where I'm less certain.
