Brass bezel tabs, repaired
« on: September 05, 2019, 04:36:18 PM »
We all know about broken face bezel tabs.  Eventually it will hit you and it did big time with a 3H86,the New Brevet.  Just picked up one on Ebay, leathette is in excellent shape, wood very good shape.  Opened up the clock to access the movement and 3 1/2 of the brass tabs are broken.  2 spots are soldered together, one missing totally, fourth one ready to and did break off when I bent it straight.  Crap.
So, I thought what the heck I can solder on my own tabs to the little nubs still on the bezel.  Got out some 0.006 inch brass shim stock, cut 4 tabs with a scissors and soldered away. Used regular electronics solder.  After I cleaned off the excess solder with a file I sandwiched the bezel-face, face, crystal and newly soldered bezel together.  It fits.  The shim stock easily fits thru the slots, around the face and even easier around the crystal.  It all fits.  I figure that if I can get it all together and the solder joints hold this clock will be good as long as I own it and probably at least one more opening and closing.

Well, finished the clock this morning.  One of my tab repairs broke when bending it.  Soldered it to the brass backing plate.  Early H rotor with welded tabs eventually sucked in oil, runs quietly now.  Wood finish stripped, recoated with satin poly.  Brass parts stripped, polished, relacquered.  Very minor repair needed on the faux leather back edge with colored sharpie pens.  Will add this one to my small collection.

Soldering is a valuable skill.  Do you use flux when soldering?  Working in electronics, I use rosin based flux and it always gives a good wetted joint and acid type fluxes I have noticed, can make the brass a bit more brittle and can break a bit easier when bent.

I did use acid flux to make sure it wetted the brass plate.  The piece broke in the solder joint.  It broke when bending beyond 45 degrees.  At least the other 3 solder joints held and the brass shim stock bent with no problems.
