Up till now, I have secured my coupler to the payload tube using these or similar (Grainger, McMaster, Zoro, Amazon).
I drilled my Formula 200 with five 1/4" holes, dropped the coupler into payload tube, and tried to stick in a rivet. Woops. The material thickness is 0.29 inches, which greatly exceeds the 0.217-inch maximum for these rivets.
For the life of me, I can't find longer ones anywhere! And I have looked at other kinds of push-in rivets, but none of them seems like a good alternative.
I guess I could use weld nuts and screws, but that is more of a pain than pushing in a rivets.
Any suggestions, or does anyone know where I can get snap-in rivets with a 1/4" shaft and longer shank?
