Lazy susan turntable (Hitchin, SG5)

Hi all

I'm looking for a wooden lazy susan (like a round small table top connected to a smaller round piece, with a kind of turntable concealed in between). I've been tasked with making a prize wheel, and from researching it, a lazy susan is the easiest route.

Attached pic is for an indication of what I mean (minus the cheese based goodies).

I can collect locally and am in Hitchin.
