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;


bike chain
1/2 in pipe
nails, or thin metal dowel
duct tape
metal plate
thin steel cable


metal saw
drill press

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

Take over the world!
or play guitar hero.

<b><a href="http://www.chanels.cc/" rel="nofollow">Chanel Handbags</a></b>&rsquo;s presentation at Paris Fashion Week involved the importation of giant chunks of an iceberg from Scandinavia, and the models splashed down the runway in appropriate cold-weather attire. My personal favorites were the <a href="http://www.chanels.cc/chanel-2008-collection-c-118.html" rel="nofollow"><b>Chanel Purses</b></a>, they were the ones that most accurately captured the frozen feeling of the collection and will probably make fantastic collector&rsquo;s items in the future.

As summer comes, I think that you may do not want to wear <a href="http://www.ugglinks.com/" rel="nofollow"><b>UGG Boots</b></a>. It is said that if you want to put your ugg boots up, you had better place a support plate into the <b><a href="http://www.ugglinks.com/ugg-bailey-button-c-66.html" rel="nofollow">UGG Classic Boots</a></b>, if not, you may also use newspaper. The general newspaper is the best choice. When you use it, you can feel that it can help you avoid moisture and odor. You don&rsquo;t need to fill up, you just need to hold up slightly and to leave gaps. From <a href="http://www.ugglinks.com/" rel="nofollow"><b>UGG Boots Outlet</b></a>.
dude we need a video of you using these things i think i speak for all of us
Where did you get the springs? Im making a pvc version with plastidip sprayed hands for better grip and the springs are all that i need to get.
Try cheap mechanical pencils or pens :P
awesome but i am gonna try to make it smaller, I am being terminator for Halloween.
i drew a picture of it.
hehehe ha. look man, it's carnage. YAY!
I tried making a flame thrower like hand thing but I just couldn't get it to work
try an arm mounted air-gun gauntlet >:D
That is a hilarious picture.
naw naw naw you need 5 flame throwers to attatch to the top of each blade finger! :D
i am asctually loling HARD!!!!
dude, thats pwnage lol
correction, play guitar hero, then take over the world. both are fun to do!
dude..... you just gave me the awesomeoust idea... so i drew it on paint.... PAINT ROXXORZ FTW! ... sorry had to get that outta my system. But yeah, i think itd be simpler than making a hand... and itd just be the coolest thing in the world to have a mechanical hand with 6inch knives for fingers.
... freddy kuegur? I hope I spelled that right.
It's kruger but that doesn't matter it's still the same kknife weilding mass murderer we know and love <3
dont know... kuegur doesnt look too right but..... i might be wrong.
dont forget the flame thrower wich u can easily make out of low cost butane burner.. its nothing without the flame thrower PS. u can get powerfull lasers out of dvd burners (they can even light a match)
sorry forgot the spring in the pic
Did you really play GH with that?
i made one out of straws and thread and the middle fingers stuck
one more thing- it should be possible to use brake cables and servos for a fully automated system with allot of strength i will try that one day
freakin sweet/huge.
could this be done w PVC?
Ive found that u can use a bicycle chain with a ribon or similar threaded through and then attached to one end makes a very good finger when the ribon is pulled. with a bit of welding u can make larger sections rigid and stop the finger bending the wrong way. this is a bit harder though but gives a nicer result. Sorry i dont have any pics at the mo. I think the mythbusters did a similar thing once
Ya they did. During the Ninja Special Adam and Jamie were trying to catch an arrow with a hand built with that technique
on a previous episode adam explained how the hand he made actually go him the job on mythbusters!
you are <em>weird</em>.<br/>
Thank you.
I think I'm in love!!!!!!!! Watch out world, here comes the DATAMAN (For trekkies, that is the data that the writers so rudely KILLED OFF) ****Excuse the offbeat part of this comment****
nice.. im gonna make something like that but it will be better and have lasers and flame throwers and knives in it..
dude... didnt even notice your comment... but yeahh itd be sweet to have knives
Nice instructable. I tried something similar on a smaller scale with some sheet copper and steel, but couldn't find anything decent for the pull-strings...
thats pretty cool
Has anyone thought of making one out of copper using copper pipe and rod? Just a thought maybe my next Instructable... hmmmmm Great job! We need more cool metal projects like this!
how heavy
I gave it to my friend, so I don't have it any more, but I think it was between 15 and 22 pounds.
how long did y this project take you?
A few hours, maybe 5.
That is the coolest thing I have ever seen
Awesome! everyone should take over the world while playing guitar hero with a giant robotic claw!!!!!!!! ......it has always been MY dream..... dude.... Awesome!
Yessss, With this I can rule the WORLD! excellent!
but i will be the one to bring down your empire! lol
Dude, so weird. I have been making a PVC version of these. Yo Zombie, I want to see yours when you're done. I'll take pictures of mine and throw together an instructable. ...Great minds, hah
