I broke a joint on a metal eyeglass frame. The local eyeglass place
that last put new lenses into the frames (they did not originally sell
me the frames) apparently does not have a repair service to direct me
to and suggested that I go to a jewelery repair. I braise and silver
solder - if I bought a "jewelers torch", would that give me a small
enough of a flame to be able to silver solder the frame? Years ago I
tried to repair a broken joint in a scrap pair of glasses and tried to
either use a TIG or oxi-acetylene (I don't remember which) but all
that I accomplished was to burn away about 1/8 inch of the frame near
the joint. That failure was no loss on the trial frames but my
current frames are in daily use and I expect to keep them in use for
another 1/2 year and then have them as back up eyeglasses after that.
