dwalker, I thought I'd try a private message.
My moniker Lendo is short for Lendich, you can find me on Face Book, but I hardly ever use it for communications, but my private e-mail is firstname.lastname@example.org.
I have thought about building an AL angle LSA. I have a concern about two rivet joints acting like a pair of scissors. resulting in the shear failure of one of the rivets. I had thought to stop that by using AN bolts of the same dia. as the rivets, washers and castelated nuts, saftied with cotter keys. The AN bolt is 3 times as strong as the rivet of the same diameter, and a lot more chafe resistant.
Tig welded. I have welded since I was a kid. Went to B&W's welding school to weld their coal fired electic power plant boilers when I young. All welds X-rayed. That was Tig and Stick. Also have gas welded most of my life. The JMR Special is my last tube fuselage, now I just don't have the eyesight and hands getting shakey.
