It's Finally done!! This is the completed Torva Armor, from RuneScape.
Made from 16g steel, and some 22g (helmet and boots), some machine screws, a few pieces of tie-down strap, some chainmail, and about 12 cheap cat/dog collars for the buckles.
Took about 3-4 months to complete.
Final cost for materials... $548.00
Helm - 3 lb.
Body - 22.5 lb.
Legs - 19.5 lb.
Boots - 7 lb.
Chainmail - 31 lb.
Total (by itself, w/chainmail shirt) - 83 lb.
Total (without chainmail shirt) - 65.5 lb.
Total (worn, without chainmail shirt) - 192 lb.
(I rarely use the chainmail shirt, as it is very heavy, and hard to move with it on.)
EDIT: I totally forgot, but an enormous thanks goes out to Brio Wolf on RuneScape for posing in full Torva for me. I wouldn't have been able to see anything but the front otherwise, and the armor would not look as good as it does if not for him.
Interesting that you think it to be thin. Traditional "knight" armor is normally 18g steel, so this is technically thicker. (It is however, un-tempered metal, so it might be softer.)
