I'm working on building a 3D Zoetrope like the Disney Zoetrope in this video. The part that has me stumped is the bearing. I bought a lazy susan bearing but it's a bit loud, doesn't have any mount options, and doesn't spin as freely as I'd like.
I also see turntable bearings that seem like essentially the same thing but with better mounting options. My worry with those is their size. I have a 4 foot platter and most bearings are quite small, which is why I went with the lazy susan bearing at 24" diameter.
Thrust bearings have also come up but the ones I've seen don't have any mount options. They seem constructed exactly as I need them with the bearings being sandwiched vertically (top to bottom), instead of horizontally between an outer and inner ring.
I've also been reading that certain ball bearings have a a radial and/or angular thrust capacity. And that this may provide the rotation I need, though again the mounting options seem really limited for a turning table.
I've been googling for days and seem to have a mental block. I don't know how I would stabilize a 4 foot platter if the bearing is small and centered, like the turntable bearings I found. So, what kind of bearing would be best for this? How would I mount it (if its not super obvious)?
I'm thinking of using a pulley to drive the zoetrope, though I'd prefer a direct connection with the motor drive shaft in the middle of the platter.
