So, I've been playing with a very cool aluminum alloy called 7068. Rated as as strong as 404 Stainless (although it prob flexes a tiny bit more). Decided to make a swingarm pivot pin out of the stuff. Figured that loaded in shear, it really can't go too far wrong (and really can't flex). Made a pin and a nut. Figure that they are so cute (and can't rust), that I can leave the caps off the ends. Goal is to knock 100 pounds off the bike. This is about 1/2 pound. It all adds up :-0 BTW, I never use the torque spec for a swingarm pin. I pull the shocks and slowly tighten the swingarm pivot nut until the swingarm just falls under it's own weight. No slop, no binding, no drag. They seem happiest this way.
