So just to follow up about my broken Apeface, I actually fixed the ratchet joint!

To keep it brief, there is basically a screw that holds the two crank style pieces together. Somehow it came undone. Anyway, it was a simple fix in the end, as I used a screw driver angled through his cockpit to reach the screw head, and just rotated his arm until it became firm and started clicking again.

Although I'm curious now, does this mean that over rotating ratchet joints is potentially no good for them?

But yeah, I'm so happy!
