Cheap 56,000RPM milling upgrade (not a dremel :)

All these compressed-air spindles EAT so much air; even the PRECISION ones
are not only too expensive, but wasteful. I built a little X-Y PCB drill
using a 400 Hz. "capacitor-run" motor which I powered via a 400 Hz. circuit I
built. VERY fine! The little motor was part of some aircraft instrument, I
think. ANYway, it is clear that high freq. motors are MUCH nicer and economical
to work with than AIR stuff; they are just hard to FIND. Can't we, as a
group, somehow interest some motor- or quill-manufacturer to make "ideal"
high-freq. motors for us? And power-supplies? Has anyone "in here" built a quill
using 800 Hz? For PCB work, 400 Hz is "OK", but it'd sure be nicer if TWICE
that! (FYI: "Real" CNC PCB machines turn 100,000-300,000 RPM!!!)
