I really thought u were using real turntables...
if turntables could take the weight...
put those on top of ur design and bam.. rotating grow
sv4run, thought you might appreciate a similar concept we've been working on:

It's for aeroponics however, so that hose you see in the front of the table is a quick connect and the golden stubs sticking out of the tables are nozzles. The table can be rotated but it's easier to switch out the buckets, as they just sit on the nozzles. Good luck!
My setup that Anti kindly linked will support 8, 3 gallon pots full of wet soil flawlessly.Skateboard setups can be had cheap at discount stores.Like 20 bucks american.
They can be screwed straight to a wooden floor.I could build my setup for under $100.
Tools required are Jigsaw,drill-driver,
Materials one 4x8 plywood and 3 skateboards and some screws
For a larger radius than 20",I'd get one more skateboard.
Good luck with your project
You doing HP aero, and if so - got a journal up somewhere? Did one run with HP (hydraulic, 100-125PSI) and then scrapped it but have been toying with trying out some AA - lemme know.
