Mac has the sanding plate on the Back End. That is the power takeoff

commented on it ripping along, as the PTO runs at about 10K. You are
correct that you can use the sanding plate on the front end and
advance the quill.

I am confused as my Shopsmith has two PTOs on the rear end, one
(in-line with the spindle) runs at the same speed as the spindle, the
other (lower) runs a bit faster. The motor runs at 1700 and the speed
control is between the motor and the lower PTO so I don't see how
either could run at 10K..

I use the lower PTO as an input shaft for my DC motor setup for
extremely slow speeds.

I may be the one confused. IIRC, the lower runs at top speed, or
thereabouts. The upper, as you point out, should run at the same speed as
the spindle.
