I've been practicing brazing on and off with the gear in the workshop at my school, but I've decided I should probably buy my own equipment if I'm actually going to build frames, as I'm leaving school at the end of next year, and I'd like to be able to keep going with framebuilding. The problem I've been having is finding suppliers for the gases. I looked at BOC's site, which is where my school gets them, but BOC seem to charge for rental of the cylinders. Is there anywhere I can actually buy the cylinders, and just get them refilled when they run out? Ideally somewhere in the Reading area, which is where I live.
Also, I'll be doing fillet-brazing, probably using regular brass. Do I have to use oxy-acetylene, or would I be able to get away with oxy-propane or something?
Thanks in advance
