Mac has the sanding plate on the Back End. That is the power takeoff end
for things like the joiner, planer, and bandsaw - which is why I 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.

No, the lower one (which only mates with the jointer and planer) runs
from 1400-10000 rpm. The sanding disc would not fit on that one - it's
too close to the ways. The upper one runs the same speed as the spindle.
Simple belt arrangement.
