I have a project running on tindie.com   for a real claw machine kit.

Step 1: Get Stuff

The main thing is the claw.  I had a hard time finding these and had to go to a supplier in China. 
I've posted them on amazon here:
Claw Machine / Crane Game -- Actual Claw  (note: this is a link to my own thing on amazon.com)

The other parts are:
  • 1" PVC pipe
  • Stiff wire
  • A spring (optional)
  • A nut and bolt (size 10-24, length is not critical, a  little smaller diameter is okay)
  • Electrical tape
  • Thin strips of wood - for handle (or something better)
  • Plumbers strap - for handle (or something better)
  • Black spray paint

Step 2: Take apart claw

The claw comes with some guts, a big solenoid, a string, and a cable.
  • Undo the two screws
  • Pry off the top cover
  • Remove the solenoid coil and string

Step 3: Remove center post

Undo the crew that holds the center post (that would be going through the solenoid)  to a metal triangle at the crux of the claw.

Step 4: Replace with wire and new bolt

  • Cut a length of stiff wire, maybe 3 feet, it should be longer than the final length of the picker upper.
  • Thread this through the hole created when you removed the center post and screw
  • Put a bolt in the hole
  • Loop the wire around the bolt, such that it is held in place at the crux
Note: this shows copper wire.  A stiff steal wire, 'mechanics wire' is better.

Step 5: Test that out

When you pull the wire the claw should close.  Release the wire and it opens.

Yeah I know -- this is pretty big claw, maybe I can find a smaller/cheaper one....

I can't get the video to show up.....
In YouTube, click the 'share' tab, then click 'embed' and copy that code. Then, paste that code into our editor with the 'embed media' button in the rich editor.
