Papa, your talking about Oxy mapp. vs Oxy propane? In the quotes I was refering to the berzomatic torch with Mapp gas vs, the berzo torch with propane. With oxygen it's all good.
"Thanks, PeterPan. I love the look of brushed stainless and considered using it for a while while I was still TIGging, but since I went to brazing I gave up on that idea. I know it can be silver brazed, but my silver work leaves a lot to be desired and practicing is so expensive I think I`ll just stick with bronze wherever possible."
I bought about 2 pounds of 45% silver off ebay, forget what I paid, but it wasn't that big a dent, and it is all safety silv, no cadmium. Not to suggest you should move away from brass. Part of my interest is playing with cheap home shop alternatives for hobbyists, and silver is one of those options, at least as far as non-oxy torches are concerned.
"OT: PeterPan, I run into your posts from time to time in different subforums and it sounds like you do a lot of different handywork. Have you ever built yourself any frames? Just wondering."
I haven't built one over the last year because I have been working on some fixtures and otherwise not spending much money. The current frame I am working on is a Rohloff expedition tourer, but I don't have all the parts yet, and I am not going to make it up until I finish the wheels... and the frame jig. I sold all my bikes last fall to finance the project but then I kinda freaked when the financial crise hit and the Canadian dollar tanked. I spent the war chest on family stuff.
