In my home shop, just now. I have been hitherto trying to get by on a propane forge, mapp gas, and TIG. I hope oxy propane works out I gather some pro builders prefer propane also. Acet is required, sorta, for aluminum welding, but for the kind of thing we mostly do propane is cleaner burning, and cooler which shouldn't hurt brazing light parts any. I think it will also work out on an economic and safety basis, even my welding supplier agreed on that, and I don't get the propane from them. Part of the incentive was that Tinman now offers specific heads for propane, which seemed like a better idea than running the stuff through appliances not designed for it, even if others are doing it.
I'd actually like to hear why others who use acet think it is better for brazing etc... Obviously it works, and if you have it under control, I wouldn't change it either, but I would like to know what the advantages are to using acet if you have the choice of either. Again, in welding, the higher heat is an advantage, generally, but for brazing the flame is mostly directed into the open air for fear of overheating the tubes, so a colder flame shouldn't be a problem.
In my own case silver brazing racks is something I wanted to do a little better and I think the propane is a little better for that.
I wasn't influenced by this blog, I come at it more from a welding end. It seems likely Alex would have sussed out the right stuff from a framebuilder perspective.
