Maybe just too much steel for a MAPP
torch. Looks like I'm going to have to fire up the oxy acetylene which
means I'll need some regulators and hose. Anyone have any for sale??
Other suggestions?

More than one MAPP or propane torch would also put more heat on the
joint, if you already happen to have another torch around. I've used two
MAPP torches a couple of times for joints that were just a bit too
massive for one MAPP torch.

You can build a propane torch with a few bux worth of plumbing parts
that will definitely do your job. Ron Reil has brazed cannon balls
with such a torch. See

I made one of these burners just for the hell of it. It works.
