C2 clock bezel re-attachment
This post is for archival purposes (in the "for what it's worth" category).
When I was putting my 63 clock back together, I found that re-attaching the bezel was an issue. There are 3 sets of 2 pins on the back of the bezel that were peened over originally to attach the bezel. After removing the peened part to get the bezel off, the pins are too short to re-peen. I checked the archives and found a post by some one with the same problem, and one of the replies suggested drilling and tapping the bezel for small screws. I tried that and it worked well. Here's the way I did it........ I filed off one pin in each set and put a punch mark in the center of where each pin was. The inside wall of the bezel is slanted, so I drilled the holes at about a 15 deg angle to make sure the bit didn't penetrate the inside wall. I used #3-48 x 1/4" machine screws. The bit size for tapping this thread is a 47 bit (I don't understand the nomenclature, but it is about 5/64"). Since the tap is tapered and doesn't cut threads to the bottom of the hole, I drilled the holes 5/16" deep so that when tapping I would get a full 1/4" of threads. (I used a drill press with a depth stop). I bought a #3-48 tap and tapped the threads by hand. The bezel is pretty soft (aluminum?). The bit and tap are very fine, so go slow and use some machine oil while drilling and tapping.
