If the tube is going into a "socket", rough up the end of the tube and the inside of the socket and use JB Weld.

I make ALL my wing struts from K&S aluminum streamlined tubing using JB Weld and have not had a single
failure. I have had a couple of "unscheduled landings" that have turned the struts into pretzels - the JB Weld
joint was still intact.

I use a product called DURA FIX. It's really easy to work with just a propane tourch. I have made muffler's, motor mount's, exsuast extensions, reinforced landing gear's and a bunch of other stuff. Check out their web site at DURAFIX.COM. and watch the videos or go to YouTube and watch from there. I think you will like it. My club member's didn't believe you could work alu without a Tigwelder. They believe it NOW. Tony.
