I put a propane blow torch to it, but the bends never worked out right.
I will try emailing orvis to see if they will help
I bought one of these years ago at a garage sale (lucky me) http://www.grainger.com/Grainger/BERNZOMATIC-Torch-Kit-33V975?gclid=CN66gJra9LUCFQqnPAodqSYA3w&cm_mmc=PPC:GooglePLA-_-Welding-_-Gas%20Welding-_-33V975&ci_src=17588969&ci_sku=33V975&ef_id=UN67hwAAVu7-qxK2:20130311125155:s . It will create enough heat to melt steel and you can get new fuel and oxygen cylinders for it at any hardware store. My only complaint is the oxygen cylinder holds a tiny volume, but normally will get me through the occassional projects I have that require a large amount of heat, such as burning off heavily rusted automotive exhaust system parts or bending a part, anything that requires a large amount of heat very quickly.
