BIKEPGH MESSAGE BOARD ARCHIVE

elaborate

I treat the bike like some Native Americans treat the deer, use every little bit. You have a frame with luggs and steel tubes. Heat the braze, pull them apart; then you have a selection of parts to build from.

Caveat: IANAM (I Am Not A Metallurgist)

I'd imagine that the results would depend on the alloy of the metal in question. In some cases, especially the high-end stupid-thin steels, you have to be really, really, really, really careful not to overheat 'em, or they cease to bend under load and instead crack.

If you're talking nice thick stuff, and/or it was brazed using low-temp silver instead of brass, you're probably better off.

It might be worth browsing the archives or asking the question over on the framebuilders list

The same temp to braze it will also un-braze.

I would not use high end frames, that would have the fancy steel. I have been chopping up bikes for 5 years now, and MIGing them together. I have found that vanity welds are not a requirement for a strong bike. They look nice though.

I have been weldig for @ 30 years now, 25 years as a Boilermaker and love it. Welding on bikes is a different art form though. If you would not mind some old guy hanging around I would very much like to stop down your shop to pick your brain some time.
