HIgh Country:

The Aluminum is just 5052-H33, which I have used before on floor boards for my sonerai and liked it as it is very corrosion resistant , cheapish and easy to work with. These plates are made from 0.040 thickness metal, but are really very stiff with the shimming in place, so I think I could have gone with 0.032 and been just fine. With shimming, seam-locks and large magnesium tube spacers in place (red and green block, see below), the total weight was 3 lbs 11 OZ.

I am not sure what wood floor boards weight, but these things are stiff as heck and strong enough too. Strong enough to act as penetration protect in the even I land on a fence or something.

With smaller spacers and shims, and using 0.032 thick metal, I think I could have built the floor boards under 3 lbs for sure.
