Giant Steel Skeleton Hand (and coat rack)

Featured

Step 1: Find some scrap nuts and bults

This project was inspired by finding a couple buckets of large nuts and bolts at a junk yard, and then deciding that i wanted to learn to weld. This project is great for your first welding project because if the welds are a mess it won't ruin the piece. There is not much measuring to do and if you make mistakes they are easy to fix or else they don't matter. You have a lot of flexibility on your choice of parts and you can easily build the hand at whatever size you want.

note: do not use galvanized nuts and bolts because they give off poisonous fumes when you weld them.

all the parts you need are shown below:

Step 2: Make the fingers and thumb

Start by making the individual fingers and thumb. If you mess one up badly you can just make more! Use a vise or a locking plier to hold the fingertip, and hold the middle joint with the ground clamp. Choose the curve angle of your finger joint and then weld the two bolts together. Repeat to add the third finger joint. I made each finger with a different curve because I think it makes the hand look more alive.

The photos show the fingers already attached to the hand, but that's just because i forgot to take a photo before I attached them. At the end of this step you just have 5 loose fingers.

The carriage bolts are nice because you can choose the curve of the finger joint more easily and they look a little better. You can still choose your finger curve with a normal bolt but it is not quite as nice looking.

As a experience welder myself I would suggest you get a nice thick slab of steel to weld on and various steel bars, especially if you plan to move up to a welding process that takes both hands (i.e. oxy-acetylene or TIG). Ground to the slab and use the heavy bars to hold your pieces in place. Yes I know htat there are situations where this is very inconvenient but knowing what to use when is how to do anything properly

Nice project. I made a hand a few years ago and this reminded me of it. Probably right around the same time you first published this lol. I used steel wire for tendons. It was all scrap metal I had. Made it for the garden.

Love your kitty,so I made one too. Along with a few boltbugs. Welding in the "eyes" was difficult, so I attached them with a nut and washers on the back. The eyes would shift during the weld. By the way, I got one of those $50 Harbor Freight A/D helmets and it works great.

This reminds me a lot of the cat from the movie "Coraline".
AWESOME! Great job, it looks sweet! What'd you use for the tail? I had problems with burnthrough on that one.
I should have arched the back a bit to make the cat look more natural. that back is pretty flat! Funny, one doesn't notice this until after it is done.
Its the iron wire they use to bundle up steel when it comes into the shop. About 1/8 " thick. I had to do it three times because I burned off the tail too!
I've been wanting to make a junk rat. (im an ametuer welder who has pet rats) and so I'm wondering where to start.
Hmmmm....... Well... I'd start with nuts and bolts, since they're easy to find and not expensive at all.

In terms of making the actual rat, make the body first, then come up with a creative way to make the head. Determine how 3-D you want it to come out, and just think out the whole process in your head; that's how I do mine =)
that homework sheet looks familiar.....what is it?
I think it's a rubric for one of my English papers..... I don't remember exactly, though... it's been a long while!
wow thats really gd!

Can you sodder them?
no the solder connection would be to weak to hold very much weight
my grandfather works at a small welding company. and this is such a bl00dy good idea i may have to borrow some equipment from him ...

Very cool! A friend made one of these for me. I use it in my Cave to hang my different work aprons.

Great instructable, Your creations are great. I made the skeleton hand and it works great as hook behind the door in my work shed.

:D i am totally going to do this! great idea!
Seems to be a popular first project for up-and-coming welders like me. I'm using a plain old manual arc welder. Thanks for the instructable, Dan.

As previously noted by other people, this project makes me wish I had a welder. I really like the idea of starting with nuts and bolts and ending up with a great coat holder. Great imagination.

Pretty awesome!! I have wanted to learn how to weld for a long time and you may have just convinced me it's time! Project 1 this ,Project 2 Skeleton!!! ps +1
as promised i finally got my arc welder today! first project, This! After that, armor for my iron man exo-suit!

Great idea, not new though. A friend of mine made a hand out of soft steel nails SMAW-welded together. Your welds do need some practice, but don't be discouraged. SMAW welding is tricky, a lot more than MIG.

The welds make me cry... Jeeze. Cool Idea very Terminator toy like.

you could use brass knuckles instead for the
palm
that would look awesome if you used blades for fingers.
