Full sized chair

[platypusguy]

My brother gave me the idea of using my origami skills in a more "useful" way and make him a chair out of some sort of thing metal. I came up with a design (one of my best). It has a tripod base, 2 armrests and a tall back. I will post a picture, do you thing that this is possible and if so, how can I do this, or find the metal.

I'm in no way a metal-worker, but it seems to me that making creases in a sheet of metal would introduce stress lines along which it could then shear. Also, if you're using something thin enough to fold, are you sure it won't buckle under the weight of an actual human being? I don't mean to sound negative, just curious!

obviously depends on the metal you use, there are alloys of steel that resist pretty well to stress points (1020 carbide steel), but they are a little more expensive. The rounder the fold is, the less fracture potential lines you create.

However, if you apply heat to make the folds you will erase every possible potential fracture line, but also you will lose mechanical properties of steel (it becomes soft iron) like resistance and hardness, so you have to temper and quench it again on water or oil to get steel back, specially on folds that receive most of the weight. I don't recommend you to use a different metal, copper, aluminum will no resist a human being unless you use a very expensive aluminum alloy.

hope it helps.

hmm maybe just get regular paper and fold it then cover it with metal because im pretty sure there isn't foldable metal.
