What model of Stanley brace is yours? I bet you could take it apart and figure out what ails it right quick.
Three braces have followed me home. One brace is in a handy 6″ size, and the two others 10″ braces. Not terribly pretty, but they are good workhorses when pressed into service. I usually keep a counter sink bit in the 6″ one so it is always handy.
It’s the spring holding the jaw lost its spring if you know what I mean.
Probably where I left it in a tightened state Stanley 10″ ratchet wooden handles.
Brace has got some numbers on it. Have a look another day.
I found this old 1 1/2″ centre bit Buck & Hickman cast steel. Company been going for 180 years so who know how old bit is.
