Have a cheapy hand brace. Chuck itself is in excellent shape. The ring-like thingy that holds the knob onto the end of the brace is cracked, and falling apart

Yeah, not good. Seems to be a "pot metal" sort of thing. The rest of the brace

Isn't all THAT bad. The chuck is in fine shape

Ratchet works great. All the parts are there.

So, need to repair or replace the knob. JB Weld the pot metal back together? How does one remove a knob from a brace like this?
