I already have a meter on the spindle. However as it has a 10hp motor
and the gearbox has a lot of drag you hardly notice the extra load of a
cut unless you are taking really heavy cuts. This beast doesn't even
notice cuts that would stall my previous lathe :-).

Good point. However I think I will forget about force feedback for the
time being. My current hand wheel design would be very easy to convert
over force feedback at a later date if I decide it is worth
investigating further.

The red swarf is usually a good indication ;-)
