I am planning on making Articulating Arm Hollowing System similar to Captains Eddies Snake Hollower or the Monster Hollowing System. I have most of it planned out but I need some assistance in figuring out what bearing I should use in the joints. I have come up with the three options below, please let me know what you think?
