Need ideas for movable finger joint
« on: May 02, 2012, 10:18:10 PM »
I am planning on building the below finger and I am not able to find a way to connect the joints in a way that they can be moved.  Is there a special screw or rivet that would work for movable joints.  Any ideas would be appreciated.

Put a bushing through the moving part so that the part moves on the bushing. Then a bolt through the assembly and bushing to clamp the bushing in place.

Or, use a bolt and don't tighten it (use an elastic stop nut so it doesn't come off).

Or, a clevis pin.
I get paid to play with robots - can't beat that with a stick.
