|Second Neck rebuild|
Originally, the head-turning was driven by a single powered axle. That put a huge amount of torque on the axle (and gears) and turned pretty slow.
I don't have a pic of the first rebuild, but it had one wheel driving the plate on the bottom of the head.
|Third Neck rebuild|
I can't believe I screwed up the gearing like that. The third rebuild works very well.
There will still be a wire coming out and attaching the brain to the LED sensor in the head, so the head can not spin 360, but it should turn very well.
That makes maintenance very difficult.
|Back panel w/Magnets|
There are four sets of magnets that hold the back on. Hopefully they will be strong enough to hold everything in place.
