Found in one of the publications I get:

Replace the stock setup with a 1/2"x20 threaded rod (the quill stop rod on
a Bridgeport mill) and get 2 Bridgeport-compatible "speed nut" quill stops
that are available from machine shop supply sources like MCS and ENCO.
The speed nut's quick release button allows it to slide free of the
threads for instant repositioning. With 50 marks evenly spaced around the
nuts circumference, and 20 teeth per inch on the rod, it is precisely
adjustable to .001".

Hope this is of use.

Thanks Jim, good to know if I decide to wait to get a new DP. That would
certainly be a "next to do" improvement.
