Hey everyone.

I'm building a sculpture and the client wants to be able to turn it if
he wants. It'll weigh around 300 lbs.

I want a large round track with bearings for ease of turning...
probably around a 2' or 2.5' diameter. It will be under the base, so
it won't be exposed to direct weather, but it will be exposed to
moisture and some dirt/leaves/whatever even though it'll be on a plate
itself.

KISS.

I'd mate a 2-piece base to it and use thick grease or a
sheet of UHMW-PE between the parts. The weight would keep
it from turning at random but it _would_ be repositionable.

Raised (1" to keep the water out?) metal base, PE sheet,
metal top set into the bottom of the sculpture, with a
double-nutted (or drilled and cotter-pinned) SS bolt to
keep them together. Half-ascii drawing below:
