Joe,

There are several methods. 1 is of course the JB weld method. Many other methods are possible as well. Some people have threaded the area if a round tube is used. Sealer is still advised, but is less likely to leak or fail on the threaded section. A light press fit is another option. Use a minimal amount of sealer just to be sure. I am trying to do a interlocked tube using a shrink fit using liquid nitrogen to cool the tube insert. As many possibilities as people doing the mod I guess!
