The drawbar sticks up about 5 inches, then there is the issues of the brake, and the clutch lever for the back gear, and the round shape of the upper section. So mounting would have to be with a base plate on the top.

Certainly lots of people have done the air ratchet type on BPs. I can't recall off-hand seeing the other kind, but I see no reason it couldn't be done. It's the approach I plan to take when I do mine. The spring washers would have to be small enough diameter to fit inside the quill bore, so no larger than the minor diameter of the quill splines. Since the quill would, presumably, be CNC'd, the downforce of the QC should not be an issue, and returning the quill to the full up position should put it in the right place. I just like the simplicity of that approach.
If you're just interested in quick tool changes on a manual machine, then I'd probably just spend the $150 to buy the air ratchet one on E-Bay.
