Well, you've sold me on it then.I've done a bit of welding in the past, but
it's been a while, and I don't have any equipment of my own. So we'll see how
the brazing goes with some test bits of tube, torque on them a bit, and get
some pics and results up for those interested in cheap metal working.
I've got both some brass and some bronze rods: both flux coated and ~$4 for a
pack of 4 sticks at my local True Value. They're both rated to melt at around
1600 degrees, so there shouldn't be any difference in working temps: now it's
just down to which is stronger, and which proves itself easier to work with in
practice.
Thanks!

Unless your life depends on it brazing is ten times easier and cheaper! I have
an acetolyene torch and it's like soldering. If you can break the joint then
you are a better man than I. Doug

Welding seems to be the method of choice for metal work, given the stresses
required of frames in this game. But has anyone had any experience / success
with brazing? The biggest advantage I see is cost, and lack of experience
required. A decent MIG setup is going to easily run into a couple hundred
dollars + gas / cored wire, fancy mask, etc.
However, I've heard some good things about brazing steel with little more than
a $10 MAPP gas bottle, a propane torch tip, bog standard flux, and some $5
brass / bronze brazing rods. Likewise, (from what I understand) anyone who's
soldered pipes or electronics can braze, with decent results (a bit extra prep
over welding, but no real $$$ outlay).
So first question: Is the cheap-o method of brazing joints so significantly
weaker than welding that it wouldn't work on a tank? Or is this a good option?
And second: Is there anyone here who can speak to the best brazing filler
material? Bronze? Brass? High Alloy / Hard Solder?
Thanks for any input, and I hope to give it a go this weekend, and get some
results up!(If anyone's interested that is...)
