Care to elaborate on that? For example, I'd find it very hard to believe that a 1/4" pop rivet (steel or aluminum) is better in shear than the shank on a graded 1/4-20 bolt.

A properly designed and setup bolted joint can sustain more shear loading than the bolts themselves alone. The friction between the two parts, as generated by the clamping load of the threaded fastener, carries a substantial amount of load in addition to the bolts. Can the same be said for rivets?

Team 95 likes to use 1/2" or 3/8" high quality birch plywood. It is plenty strong enough and is lighter and more visually appealing that 3/4" construction grade plywood.
