I have a hinge on the temple rod of a pair of spectacles that is

fairly inexpensive tool that would help me remove this?

A file or a small grinder.

I would like to remove this and add a fresh hinge. I think that the
frames are some kind of nickel alloy. I was thinking of using this
"Silberfix" hard solder 62% Ag without Cd that has a melting point of
650 C and is suitable for bronze,nickel, stainless steel.

In my part of the world I believe the optical people use 'easiflo' silver
solder/brazing rod for spec parts. Melts at 610degC. Well tough enough.

Do you think this would be tough enough? Is there some inexpensive
device that will allow you to solder at 650C?

I found this:

would this do?

Probably. The deciding factor is how much of a heat-sink is the part to be
attached to. Being a temple I guess it'd be alright.

Where are you getting the fresh hinge from?


I'm in the UK

Don't forget to vote next year.
