How did you solder it and with what? Does soldering not remove
the galvanized coating?
Use a tinners iron - I have an electric one - the original
"tinner's iron" was heated with a blowtorch. Flux the galvanized
and solder it together - the zinc stays on the steel.

DON"T try soldering it with a torch. You WILL burn off the zinc,
and it will rust bedause you will overheat the joint.
I soldered mine with a torch and didn't burn off the zinc. I used
regular lead fee plumbing solder and paste flux. The solder melts
at a much lower than it takes to burn off the zinc. You need to
keep the flame moving. If you let it dwell it can then heat up a
spot enough to damage the zinc. There are available (at least
there used to be) soldering tips for a propane torch that fit over
the torch head and use a screw to hold them in place. One of these
would work very well for soldering galvanized sheet.

I assume a propane torch?

A soldering tip for a propane torch sounds like a great invention.
I have never heard of one.

I think I still have mine, which I bought 40 years ago. But I find my
450 W iron more convenient to use.

An online search yielded zero results. Am I understanding it
correctly, a tip that attached to a propane torch and the torch heats
the tip and the tip is what you solder with?

I would love to have a hi watt electric one but they are rather
expensive to buy for just one project....


I'm surprised , they've been around for a long long time . I've had them
in torch kits I've bought , and Dad had at least one when I was growing up
(and I ain't young) . I know this because he used it to solder radiators .
He was a DIY guy , I learned from him ... I'm a DIY guy too .


I just did a quick search and I couldnt find them either. Rather odd
actually.

Ive got probably 5 or so of the copper tips that go on (usually with
a thumbscrew) the end of a propane torch, to solder with. They came
with each torch "kit" (usually in the metal box, right along with a
"fan" tip for paint scraping/large area heating etc etc). Anybody
want one...drop me an email with the OD diameter of your torch tip
and Ill see what I have. I normally use an acetalyne torch
(portable about 18" tall) with the proper hose/regulator/torch for
heavy soldering/heating in the shop..

but still have a dozen or so propane torches (for 1lb bottle) in
various conditions of usable

Could a person make one somehow by just putting a copper tube over the end of a torch and closing one end into a flat surface???
