Robotic Arm/hand Technique Needed!

Okay, I need help with my WIP Jedi's robotic hand/arm. I've tried using superglue to join a bcut up hand and a cut up droid arm, but it keeps breaking off. Doesn anyone have good ideas about an alternate design or way of connecting?

Use steel wire, you know really thin. Drill some holes. TADAH!

What about the arm in the Agents line.
This one.

What I do is that I get a droid arm, and twist it in two. This will cause one end to be slightly pointed, and should thus fit into the hand hole.

Take the viking horn and shove the horn end into the arm hole. I've seen it done before, but I can't find an example.

I found a pic of it for you.

Thanks that's exactly what I was looking for.

Edit: This piece also works in an old torso.



Cut the bottom of the T off so you have a straight piece with the ball in the center. You can them jam the piece all the way into the arm hole so the ball in the center fills the arm hole.
Its a more stable connection and easy than the horn technique if you can spare a T piece to cut up.
