These are some pieces of armor I made experimenting with dishing metal around the time I built my Nano Gauntlet. All pieces are cut from 16 gauge steel.

Cutting the pieces out, dishing them and test fitting as I go.

Now for the hand.

Painted black.

Assembled with a fabric inlay on the inside riveted together using rapid rivets and trying it out.

You can also wear it under your shirt if you want to be a cyborg.

Another one I made for the opposite arm using a slightly different design.
