[SML] Hovercraft revolve?

[Jon Lagerquist]

While not as exciting as a hovercraft or marbles, I have spun a 10'
diameter 1" thick turntable on UHMW strips. Concentric rings of 12"
strips of 1/8" on the floor, crossing pieces on the bottom of the 1/2"
ply deck and a 1/4" skin. This unit did have a scenic piece with casters
that crossed center, but I expect that a full disk would work well. I
expect that moving it with a load would be comparable to dragging a
pallet over the floor.
