After an 8-year hiatus I'm planning on getting back into jewelry making - mostly working with silver. I tend to collect hobbies, and thought lampworking might be fun. I understand that the torch specs for silver soldering are different from those required for lampworking, and that I wouldn't be able to use the same torch handle for both applications, but I know I read a post by someone here who said they had a separate torch handle that they connected to the oxy-propane set-up they used for silver soldering when they wanted to do lampwork.
My question is primarily about the whole issue of LP tanks inside. Everything I have read indicates that it is illegal to have a portable LP tank in your house if it holds more than 1lb of gas? Is this correct? I'm questioning this because the Smith Little Torch oxy-propane set-up uses a 5-lb LP tank in a configuration that is very obviously portable and meant to sit next to your jewelers bench. As long-standing, reputable companies, (both Smith and Rio Grande - the supplier whose catalog I'm referencing) I think they would be well aware of safety codes concerning the fuels their equipment was meant to use, and wouldn't sell something that was in obvious violation of safety codes. I also have never known any jewelers or silversmiths who had the fuel for their torches outside unless they were the really big tanks. Mostly I've used the B and MC sized tanks for oxygen and acetylene. Is a jeweler's torch system somehow qualitatively different from a lampworker's torch system in regards to code requirements? Do I have the max limit for size of a portable propane tank wrong? Why in all my years of silversmithing have I never heard any of the professionals insist that fuel tanks must be outside your house? There must be lampworkers out there who also do silver soldering. How have you dealt with this issue of not wanting two completely separate torch systems?
I hope this all makes some kind of sense I'm trying to determine whether I should pursue this hobby, or just accept the fact that I can't do it safely where I am and give up on the idea.
