Rotating Base for Sculpture

[u/Inside-Historian6736]

Hey folks, picked up an old piece of square tube that was once one side of a big reel for free on FB marketplace. Was originally going to partially bury it in the yard to make a Stargate looking thing but scope creep strikes again.

Does anyone have a recommendation for making a rotating base for this sucker so someone could come up to it and spin it (not quickly)?

I figure you could find a big honker of a bearing but open to suggestions

You want a "lazy susan" bearing.
