Was missing some locking screw parts on my UPA2, had no idea how it worked but found these:

Turns out I was missing the plunger and the stop pin so I just made them.
I cut the plunger from an 0.083" gauge pin (about 5/16" long) and made the stop from some 1/8" O-1 (0.050" pin 0.170" long).
This sketch from one of the posts shows how it works, it's meant to stop the screw from backing out and flinging the little ball across the shop.
