Overheating is *never* a problem, being that it's slow and I only heat it
enough that the brass flows. I would suppose a good hot O/A torch could
be
a little ornery in this regard, but I haven't used one yet so I can't
say.
I'm sure it's nothing experience can't fix...

Done much brazing? Thought not. Low heat causes the whole shebang to
heat up to the same temperature - very slowly, and the last 5 or 6
joints you just finished remelt and fall apart.. Using a good hot
torch makes your new joint before the heat gets to the old one.

I think they have to awfully close together to make that happen when
bronze-brazing. That happens in soft soldering, but, if you're brazing steel
wire, I think you'd have to be overheating the joint outrageously to make
that happen unless they're right next to each other.

I've had no problem brazing up charcoal grills with a big propane torch or a
MAPP torch.
