Introduction: Giant Metal Animatronic Cyborg Hand of DOOM!
It is useful for taking over the world.
I thought of it after I saw this Simple Animatronics
Step 1: Materials
for this you will need;
1/2 in pipe
nails, or thin metal dowel
thin steel cable
Step 2: Measuring and Cutting
Measure the bones in your hand, don't forget the ones that go from the fingers to the wrist. Double all of your measurements.
Cut the pipe to the measured lengths. You should have 19.
Cut the ends 45 degrees, except for the fingertips and the wrist.
Step 3: Hinges
Use the drill press to remove the pins connecting every other link in the bicycle chain. You need 14 hinges.
Step 4: Cutting
Cut the nails or dowel into 28, 1 1/2 in segments. 14 will work, thats what I used, but 28 is better.
Step 5: Finger Welding
Weld the bicycle chain hinges onto the finger joints.
Weld the nails beside the joint to prevent the finger from bending backward. weld it onto the lower segment, not the top, because it looks cooler. if you have 24 weld it on both sides of the joint.
weld a nut at the end of each fingertip.
Step 6: Finger Alignment and More Welding
Cut the metal plate to be the palm from the pointer finger to the pinkie finger.
Position the fingers correctly on the palm and weld them there.
Cut the rest of the plate to be the palm from the thumb to the pointer finger.
Position the thumb on the plate and weld it there.
Weld the thumb palm to the finger palm. (if you think it will work, you could try welding a hinge in there so it could grasp better.)
Step 7: Arm
Weld a pipe onto the outside of the thumb and pinkie at the base.
Cut the pipes where they reach your bicep when your fingers are touching the wrist.
Make double sided duct tape arm straps (sticky on the inside)
Step 8: Rigging
Cut the cable into 5, 2 foot lengths.
Crimp one end on each of them.
String them through the fingers.
loop each around your corresponding finger when your arm is in the straps, and crimp it together.
Cut off the excess.
Step 9: Rig Springs
You need 14 moderately powerful small extension springs.
Hook each end of the spring onto the holes in the bike chain hinges.
Step 10: Take Over the World
