[TheForge] metalworking question- soldering brass

[Mark A. Pesetsky]

Now that sounds like a REALLY fun project!! Preserve the patina? Dam,
that is going to be a challenge.

Good Luck

Subject: [TheForge] metalworking question- soldering brass

An architect has asked me, in the interest of the tightest, most crisp
joint possible, to try silver solder on the butt joints of a red brass
hand railing.
Having done a couple houses full of copper plumbing, I assumed that this
would be easy, but butt joints seem to be a different animal altogether.
Best results so far have been with jewelry grade solder, but it has a
tendency to run all over the surface and the pipe should probably be
acid cleaned before soldering, and the architect is trying to preserve
the patina on the railing as it is.
One problem is that the joints have to be cut very precisely to get a
solderable joint, and that means expensive saws with lube that would
have to be cleaned off somehow...adding steps and expense.

Any suggestions, or does anyone know another active metals list where I
could get some suggestions?
Thanks!
Andy G.
