Are we talking about a Bridgeport or a mini-mill? Are we talking about
moving the Bridgeport knee or quill? Or on a mini-mill, lifting the entire
head, or just the quill? It makes a huge difference!

I set up my Bridgeport with about 1000 Lbs of linear force available for
X and Y, and 200 Lbs for the quill, as 200 Lbs is the correct setting for
the overload clutch on Bridgeport's quill power feed.

Of course, 200 Lbs of linear force would be a huge mistake if you were
moving
a bridgeport knee instead of the quill!
