Joining broken zinc casting
Joining broken zinc casting
(OP)
Anyone have any techniques they have used successfully to repair a small zinc casting (<1/4 lb)? This item has sentimental value to the owner and has become a challenge to me!

Also looked at tin/lead solder but had no luck there. Low melting point and rapid heat transmission rule out silver solder.
Thought about TIG with a backing dam but I am uncertain what might work as a filler.
If all else fails, I may use the parts to make a mold and cast a new one.

There are number of solders that will work but the secret is in the flux. It was no problem when you could use Cadmium in the solder

It also has some nasty health effects.
