Buzz sends me the pipe with neck transition attached, the top cap, the triggers and screws to mount them. I drill all the holes, cut the slot and assemble the stick.
To secure the eye control at the slot, I have inserted ethafoam. The sharp-ended screws that mount the triggers penetrate the ethafoam and hold it in place.
This is still a work in progress (as you can see by the extra aborted holes drilled in the stick), but this first one is pretty close.
The final test will be attaching the stick to the head and seeing how smoothly the controls operate the mechanics.
