Soldering Brass to Stainless Steel Plus How-To Make Flux

This video shows how to soft-solder brass to stainless. The same technique will solder brass to brass (or copper, or any copper-alloy, or nickel, or steel, or iron).

Soldering steel/iron to steel/iron is a little trickier but works pretty well the same (just takes practice).

Stainless is usually a tricky metal to work with, but for soft soldering it's pretty easy to use. Just be sure to use an aggressive flux like I show in the video.
