All I can say is wow! It works- it’s alive!!!!! I have 16 vertebrae and 8 are moving precisely like they are supposed to! Stage 1 of the tentacle- from the tip to vertebrae 9 is moving and curling. However, for some reason, stage 2 is barely moving. Current working theory is that the brake cable housing I am using is too stiff to allow the stage 2 mechanism to move at all. I may have to make another base plate that has no large passage holes and screw all the brake cable housings into that so that the bare cable is running through the passage holes of the actual tentacle.

I am still waiting for more set screws to arrive so I can finish attaching all the vertebrae and the tail tip. While I am waiting, I have started designing the next mechanism!!!
