I agree with DMS- LP/Oxy is plenty. In fact, you can simply steal the LP tank from your bbq grill and using bottled oxygen or a medical oxygen concentrator, you'll have plenty of heat to braze with bronze. There is a long thread here with a bunch of good info on the subject. Granted it's regarding the manufacture of bicycle frames/forks, but it should be relative. Since LP is so much less expensive than acetylene, I bought a few torch tips to give it a try. O/A is easier to control (for me), but LP works fine. Can't gas weld with LP, but I'm planning to buy a cutting head for my torch since that works.
Brake post mounting is a common use for bronze in bike building, as is attaching pretty much everything else.
Plenty strong, and completely withing the capability of an aircraft torch and LP/O2. I can't personally speak to the oxygen concentrator part, but I'm thinking I'll give it a look one day. I like the idea of not relying on Airgas when any 24/7 gas station has LP tanks and you make Oxy in your garage. High quality bronze, silver and the associated fluxes can be purchased from Cycle Design Group or Henry James (Harris & Gasflux stuff.) The bronze flows really well, and the flux washes off in hot water. Much better than the flux-coated rods in the bargain bin at the local weld shop where you have to chip off the flux.
