Hi, I am very new to the forums, and a new hobbyist as well.
I am attempting to create a Halloween animatronic wherein a skull (very lightweight styrofoam) raises 2-3 feet off a pedestal. There will be a semi-sheer material over the skull, so anything used in the lifting of the skull will be hidden by the material. The pedestal is hollow, so it can house any needed infrastructure to raise the head.
I originally thought of using a rack and pinion gear to raise the skull, but after some research thought that perhaps a worm gear (screw) would be a more appropriate approach to raising the skull. I.e., skull is attached to end of worm gear, motor moves worm gear up (probably through conduit), hence moving skull up.
In looking around at various online hobby sources, I dont see anyone that carries "long" worm gears (screws). Which makes me think that perhaps there in another, better way to accomplish this task, as there doesnt seem to be a market for long worm gears (or not that I can find anyway). I cannot use a pulley system, so the skull really needs to rise from below.
Hoping for input, thoughts, good ideas? Any input is greatly appreciated!
Tx.
