[QUOTE="ntsqd, post: 2649893, member: 93138"] I'd look into Miller-Stephenson 907. Unlike Devcon (which I like and use extensively) it is made to do what you need to do, bond metal together, in this case, aircraft parts. The problem that you're going to run into no matter what bonding agent you use is not a lot of surface area. All these bonding agents have their strengths reported as "psi", pounds force divided by area. A large bonding area is crucial to success. If you can do something like bond a thin strip on the hidden side across the break you'll gain a tremendous amount of strength. I'm guessing that the broken part has the s/n stamped in it, too. Even if a replacement was available, it wouldn't work for that reason. I wouldn't expect a welder with extensive experience in Dual-Shield welding (my guess as to the process used on submarines) to know the first thing about GTAW. They might have been exposed to GTAW way back in welding school, but that doesn't make them experts in the process some 25-40 years later. To a certain point, welding is welding, but each process has it's own tricks and nuances that have to be learned by doing. [/QUOTE]
