The tricky part is getting two drive axles down to the head - one for rotating, one for releasing. Here's my first working prototype, with heavy reliance on the relatively new technic connector with 2 axles to get two axles between the liftarms. I'm waiting for parts from Bricklink because I only have ~5 of the critical part (and then only because I added some to another order a few weeks ago).
