Zelph, where did you get the torch from? I bought a cheap one from lowes yesterday, but yours looks alot better. How much was it? Is the flame adjustable?

Make sure the joints look real purdy like this. It's part of a diesel stove I am designing. Make it real clean, use flux and lots of heat.

I used the real thin electronics solder that is made to work good with copper. It also doesn't plunge the heat down fast like the larger stuff does. Once hot I can feed about 1 1/2" per second. Also did a trickier one soldering that same copper tubing to a silicon bronze priming cup. I haven't soldered bronze too often so I crossed my fingers.

Good to know......what's the material you're soldering to the copper?

We used to have to do a lot of soldering between copper pipe and larger brass fittings fixing jacuzzi and swimming pool pumps(17!) in a special set of condos(Moana Luan) in Hawaii..that all suddenly started failing when I started working there.We would heat everything up to the point of having molten solder on top,wrap it in a wet rag real fast, and it'll suck the solder down into/between the fittings,getting a better solder joint and total seal..try that. ;)

Silicon bronze. The solder is good I was just extra generous with it to insure it will not leak when it gets hot. It drank it up and I just kept feeding it.
