As requested, theses are the blueprints for the gauntlets I've made (See Larp Armor v3)
Use collet (3-4mm hard leather) for the plates and soft leather for the straps. Adjust the size of the plates and straps to your hand. Do not splat the rivets too much unless you want to plays a lego character.
Because I'm a perfectionist (or a masochist ?), I made the gloves myself. If you're lazy or smart, use thermal resistant gloves from the local wallmart, they are quite comfortable. The gloves are only fixed to the L0 and L1 pieces.
