We need some build pics Fog. Does it turn? 

Pretty simple plan. Base is made from 3/4" ply. Circles were all cut from 3/4" ply on the bandsaw. Dowels have a 3/8" hanger bolt on one end and a threaded insert on the other so everything breaks down for storage.

 Certainly looks great all lit up. Did you allow for power to run up through the center? 
I drilled 1" holes adjacent to the center, 2" dowels. One on each level was sufficient. There are adaptors for multiple plug ins for houses and accessories screwed to the bottom of the second and third levels so all cords go there. Wifey wrapped furry stuff around the dowels after to hide the cords.
