Re: Types of Metal
3/4"x3/4"x.035" Chromoly Steel (Available at Aircraft Spruce) is wonderful if you can weld (not as tricky as aluminum i don't think).
You can use 1/2"x1/2"x.035" as well for areas under less stress. The stuff is super light, (about the same as aluminum), more compact than 1"x1"x1/8" box aluminum, and three times as strong. Cost is the only downfall but it isn't anything too unrealistic. Teams 269 and 1501 tend to work with this stuff and both come out with VERY solid frames.
ITEM is a similar solution to 80-20. Don't have a source but I've heard it is stronger than 80-20 as well.
Other than that, on 171, we use Kit of Parts frame and 1"x1"x1/8" or 1"x2"x1/8".
