I found a Zydeco frame. It fits me. I am a short captain, and it is so hard to find a tandem that fits. And within budget. It's either a 2005 or 2006. Going through the bike today I discovered a cracked head tube. It is not simply chipped paint. I bent an end of a straight pin and felt around inside of bearing race gap and there is a ping where crack goes all the way through. Better to discover in my workshop than on a screaming downhill...Right?

My mechanic mentor tells me this is not a death sentence for this frame. I need to find a good aluminum welder. And once I do that, what instructions or do's and don'ts do I give this welder? Any pitfalls I should expect. I could care less about the cosmetics. I want it to be safe and sound.

Any suggestions?

Thanks.
