Riveting up a frame

[FourPenguins]

We riveted our upper frame last year (1/8" aluminum riveted w/ 1/8" aluminum rivets) and it worked pretty well, but as someone already mentioned, rivets don't take heavy shock well.
Also, repairs can be a bit tricky. We found that in most cases it's easier and faster to add more rivets than to replace the old ones, which is fine if you're using small rivets, but on the kit frame, you'd need some big ones. (We didn't rivet our drive base.)
