Buying tools for our trade is always a difficult choice. I was lucky
as a young man to be a motor head, and built body frames onto 1920's
cars out of welded steel tube. This needed a small oxygen/acetylene
torch with hoses regulators and ,here we call them gas cylinders. i
borrowed this set up from a friend, and with a few tips from him and
some trial and error, got on with it. so altho rio Grande provide
kits of professional brazing tools, id suggest you go the following
route. go to your nearet large town and look up welding suppliers.
Go and see them, explain your need for a small welding torch. they
come with different removeable tips for differnt flame sixzs. ask for
oxygen and propane tanks. you wont need acetylene unless you want to
weld steel. (for that youll need dark goggles) and do your leg work
looking around. also go to a car body repair shop, ask what gas
tools they use, and ask where do they get their supplies. IE ask
someone who uses the kit, ask to look at it and if you smile nicely
ask for a demonstration!!. Let us know how you get on..
