Any tips?

Cannibalize dollar store readers for a replacement temple piece.

You can braze with propane or MAPP and air.

A soldered butt joint won't typically hold, but it may work if you
splint with a bit of steel or stainless wire there (any old guitar
strings around?). You can gammon with fine Nichrome wire sold for
ignitors on eBay.

This fellow uses silver solder to repair glasses. Not to be a shill for him, but we used him for DH's
glasses, and he did a fine job.
