Re: Best Practices for Not Crushing Thin-Wall Tubing
The solution that I would recommend would be to only bolt through a single wall. That can be done by either the use of a rivet nut, an access hole on one side for the fastener, or to keep the bolt head accessible a sleeve around the bolt. The access hole is a pain since it makes it difficult to remove the fastener.
Filling the tube with something isn't bad at the end of a tube but is a pain in the middle of the tube. It would be the strongest method since it allows the fastener to work on both sides of the tube.
