So I've read that the best way to fill a small dent in my son's
bicycle frame is to braze in brass. Now, I've never done this before
but I'm also advised to use low heat to avoid weakening the structural
integrity of the frame's tubing.
Questions:
1) can I use my propane (v) torch to do this?
(http://www.bernzomatic.com/bernzomatic/consumer/jhtml/detail.jhtml?prodId=BernzoProd100026 )
2) what sort of brass should I look for and where?
3) is this beyond novice skill level?
4) anything else to know?
I've also heard that I could use lead, and I'm pretty sure I could
melt some fishing sinkers into the dent using my propane torch, but
brass is supposed to be better (should we ever want to have the frame
powder coated or chrome plated). So I'd like to use brass, but if it's
too difficult I'll probably just go with lead since our intention now
is just to prime and repaint.

Use this with MAPP gas it burns considerably hotter. I don't think you
can get the plain jane propane model like you have hot enough.

I have brazed with it when a regular propane torch would not get hot
enough.
Practice on some junk stuff to get a feel of it then go for it. You
can find brass rod at any home depot type store.

D'oh!!!
(Charles has no appreciation of BMX bikes. He'll scrub the spoke
nipples on his YZ though ;-)
