First off, I have zero experience brazing (or welding for that matter) anything.
I've got a motorcycle with a few significant holes in one of the mufflers. Given the advanced age of the cycle and the prohibitive $$ of a new muffler, I'd like to try my hand at brazing and cover the holes.
the muffler is thin (< 1/16") chromed metal. I've got a small dual-gas torch setup, and could use either propane or MAPP with oxygen for brazing. I'm looking for recommendations on:
- type of gas to use
- Type of brazing material. As I noted I have no experience brazing. I'm guessing there's probably different types of brazing filler for different applications, temperatures, etc.
- Type of flux. See #2, above.
- Tip size to use... I'm guessing the smaller the better given the thinness of metals I'll be working with.
I'm planning to use some scrap metal for my patches (have yet to search my basement for supplies) and I'm thinking something thin enough to bend by hand or with a mallet and wood form like a coffee can. Would this work?
Any tips on brazing, DO's and especially DON'T's greatly appreciated..
thx
Dave
