Filling a casting void using brass colored solder
« on: March 25, 2024, 10:31:53 PM »
I have a casting of a coffin lid Patchbox with a fairly deep void on the top edge of the lid . It is too deep to file out so my thought was brass colored solder.  Has anyone used this successfully and if so how was the color match?

I've seen old pieces with voids filled with just plain solder and you can also solder in brass patches.  It all works.

Do you need to clean up and prep the area, similar to how a dentist drills out a cavity, prior to filling with solder? Or do you heat up the part and let the solder flow into the rough void? Thank you.

Clean it up and Flux it first.

This old post of mine might be a help....as Mike says, clean and flux the $#*! out of the void before you use any solder....
