I've got some stuff with sealed bearings to play with which is a larger diameter than the originals which will reduce the surface feet per minute,probably an improvement.If I have to move the poles outward much I can always enclose them in streamlined blisters if they poke out.

Thank you for the feedback, I was a little concerned about the longevity of the bearings, so your points about the lack of dust seals reinforces my fears that they may not last, even if they were greased initially. How about this idea then, instead of using lazy-susan type bearings use one real automotive quality sealed bearing (like a rear bearing from a front wheel drive car) with a through bolt to hold the plastic right in the center? Thoughts?
