All that you need is:
-Cardboard, or hardpaper (in this case I used estructural cardboard)
-some metal scissors or hard scissors (and hard fingers)
-a soft cloth glove (gray color works great, but if you want to tray use a black one with metal spray over it, to give a special effect)
-Silicon glue (cold or hot)
Other things you can use
Step 1: Let´s Draw
"you can use your glove to make the copy but it need to be a perfect fit".
"Remember every finger on your hand has 3 bones or phalanges"
We are going to draw the metal cover of the 1st an the 3th drawing a bone a little bit bigger than the phalange.
(only do this whit the 4 large fingers)
and you are going to graw the cover of the lower part of the hand(making a hole to make freely your thumb)
the thumb is composed by a little oval and a half oval, larger than the thumb.
in the 2nd hand you are going to draw the 2nd phalange and the upper cover of the hand (this is the part where the real glove has the mechanism at the view, I simply draw it :P)
Step 3: Cut It Off
After cutting all the parts you can test it over the glove to check the size of the cardboard fingers.
ypu can make 3 copies of the upper part to give some realism in to the mechanism
Step 4: Sticky Fingers
"Warning: do not use the hot silicone when you have your hand inside the glove"
now just asemble the parts over the cloth glove, after assembling the parts wear the glove, and make pressure to fold the borders)
Step 5: Coming Handy
Now let?s finish the job!!!
Step 6: Groovy!!!
Give some details over the rectangle to let your arm move freely in the elbow.
Then just paste the arm shield with tape, and give a final texture with the chrome paint in spray.
"Note1:you can use it as well to make metal hand of a berseker manga char
Note 2:you can use fiber glass to make harder your gauntlet"
