I can reasonably solder electronics although I get an occasional cold
solder joint. I have this pair of glasses I didn't wear much which
cracked near the temple joint. (The temple cracked). The repair shops
ask too much, compared to what I paid for the glasses. I tried online
to find temples, to no luck. So I'm considering soldering it. My
uncle (a retired EE) told me it would never hold. Part of the problem
is it cracked very near the screw joint. and so would suffer a lot
more torque than if it was further back. Any tips?

Yes, buy a new pair of glasses.

Will it hold? We can't tell you that not knowing what the material is that
you are soldering. It may be brass, titanium, zinc, or something else. If
they are junk now, you have nothing to lose so give it a try. Worse case
scenario is you get a new pair.
