I've got a copper loco type boiler that I'm working on that's about 90mm (3 1/2") in diameter by around 380mm (15 3/4") long, but I'm having problems getting enough heat into it to perform silver soldering. Repeatedly heating it up to fill in leaks and put bushings in is leaving me short of gas very quickly. The obvious solution would be to use oxy-acetylene, but the cylinder hire and gas fees for even the small D size cylinders would cost me well over $500 a year, and that doesn't include the expense of the other equipment needed. It seems you can't buy the cylinders outright in Australia, so oxy-acetylene is out of the question as far as I'm concerned. What does everyone else use for this kind of work? I've currently got a Primus LPG torch and a MAPP gas torch, and I have been using a hearth.
