The other day Shelley from Half-Land was going on about these ball and socket joints she was using for the little stop-motion figures she was using for her movie…
… so um… if I had to make these joints, this is how I would do it. This is the Kiwi version.
Looks a bit like some sort of makeshift prison weapon. This is the detail:
You could probably make bigger ones with wooden beads… but the general principle of using rubber bands to apply pressure to the join is kindof central. And adjustable.
You could possibly do something with heat-shrink tubing as well – for a (much) neater fit etc. I found the little rubber washer things work quite well as well. This example (as you may have guessed) is not in fact a chopstick, but is a bit of dowel.
Rough, ready and uber-cheap.
