You need to be careful about this. To do this correctly, the frame may need heat treating (6061 tubing) or artificial aging (6061 and 7005 tubing). That also means a repaint. Does your welder have an oven to do the heat treating of a bicycle frame? If it was me, and the components were worth reusing, I'd be looking for a new or used frame on Ebay, or a used bike on Craigslist, or a complete new bike.

IF Danny is still in buisness....he was building an aluminum frame airplane in his shop.... but I do agree....unless the frame is a real whizzbang it would be cheaper to buy a new frame....

WOW really did not think it was a big process. I could not find Danny's number but called around other shops. they pretty much said the same thing. I've been looking on ebay and craigslist my only problem is its a high end racing bike. I do not want to spend another 4k on a bike but looks like that might be my only option...

Could one stop drill the crack and then do a carbon fiber tape repair?

That stuff is considered better than steel or aluminium for spars in the boating community.

Do they do bike frames in it?

Answered my own question...It actually sounds like you could repair a tube that way but it also sounds like an engineering development effort.

It does not sound feasible to weld the crack though.

They do full carbon frames, aluminum frames with carbon forks, and aluminum main (seat, top, and down tube) with carbon fiber stays (seat stays and chain stays) and fork. I believe the carbon tubes are bonded (glued) to the aluminum parts.

Along Nellis Blvd North of Charleston there are several auto and tire repair shops that do welding. They charge only a few bucks.
