Rotating wing stand - rotisserie

I am approaching the need to begin work on the wings (good stuff like light wiring & bad stuff like possible de-sloshing). I would like to build a rotating stand much like the fuselage rotisseries I have seen. Does anyone have a representative one I can shamelessly copy? Would like to build it out of 2X4s and such. I suspect engine stands will be overkill. Thanks in advance!

I took a Dozer cutting edge, chop drill and weld, I put extensions on the engine stand legs and there ya go, this is how I painted my wings!

I've seen people slip a 3 or 4" PVC pipe through the lightning holes of the wing ribs and resting each end of the pipe on a saw horse. Use a second smaller diameter PVC pipe (closer to trailing edge) to lock right-side-up or up-side-down.

Here's what I used. Worked great.
