Vintage Dial Construction / Assembly
Posted: Tue Jan 14, 2020 3:08 pm
I have this nice, old safe deposit door that has a Yale OC-5 lock on it. The dial is missing the "coin" (what is the proper name for this part?).
I believe this is what the part originally looked like...
How were these assembled? I see a spline key inside the recess in the dial face. Did the "coin(?)" have a female threaded stud on its back side? Was the spindle threaded through the dial and into the "coin", then the spline key inserted from behind the dial? It looks like the "coin" would index on the four grooves to prevent turning after assembly?
Any idea where I can find the missing part? It's the smaller, .915-ish" diameter "coin" size.
