|I have a carbon tube/aluminum lugged frame that has had one of the bonds fail. Its where the drive side chainstay goes into the dropout. This bike is no longer under warranty and the manufacturer doesn't want to repair it. I'm wondering if it would be possible to re-glue this back together so its at least usable. The dropout can be pulled about 1/4 inch out of the tube so glue could be easily applied.
Anybody think this would work? If so, what would you use to try to bond it together again? Thanks.

|there is no way I would fool with it. The consequences could be really, really bad. I have a friend who still rides a bonded Vitus. He has had his professionaly repaired twice. I'm not sure who he used but you may be able to hunt around and find someone.
If you have a real emotional attachment to the bike spend the money and have it repaired by a profesional. If not, used frames are a dime a dozen.

|This is what you hear when builders talk about how they bond Al frames. I don't think this stuff is available at WalMart, though who really knows. I also expect that there is some surface preparation, including a primer, required to get good adhesion. I assume that you know someone who knows all this stuff, knows how to do it, and is good at it. Otherwise, this frame belongs in the recycle bin.|

|H.H. Racing got their start repairing bonded frames so you might want to give them a try.
It could be repaired by yourself although I'm not sure how long it would last. The key is to get the joint apart enough to clean the bonding surfaces. Fine sandpaper followed by alcohol should work. To bond the joint back, use JB Weld. This is how framebuilders attach the carbon rear seatstays that are getting popular these days.
One concern though is that the bonding surfaces have been degraded. It is customary to anodize aluminum parts before bonding to aleviate corossion. With this removed the bond will not last as long. If it were me, I would give it a go but watch the joint carefully to make sure it stays tight.
