Forget 1114, look at 148!
All of that aside, we use:
2x1 aluminum tube, 1/8" and 1/16" wall. We use the 1/8" wherever there are bearings in the tube, and 1/16" when we don't need the strength or aren't worried about crushing.
1x1 aluminum tube, 1/8" and 1/16" wall. 1/8" wall is more common for the strength. 1/16" wall is rather rare but comes in handy for small stuff (like our can stabilizer last year or climber hook depositer this year).
1/8" aluminum plate, for most gussets (although this year we used 3/32 with a hole pattern to emulate a versagusset).
1/4" aluminum plate, for bearing plates and especially for when we used tapped plates. Beats using a nut and wrench in a tight space any day. Plus, it works great for screwing thing tubes together.
1/2" hex shaft for nearly everything. 7075 from Vex. We got a run of too-tight thunderhex, but apart from that I think it's great stuff.
