Yes, these are terrific when in use. But a PITA when I have to store them. Which I haven't had to do for a couple of years, which explains why I am storing the engine from the ceiling.

The stands are simply 20 inch "plough" discs (as in agricultural) that have 2 7/8 inch tubing (oil field variety) welded to them. Originally they had saddles welded to the top, but they were a bit taller than required, so I cut the saddles off and notched the top of the tubing to receive the jack point tubes.

If I were to do them again (which I might after I am done this restoration), I would weld half a threaded "collar" (the piece that is used to join tubing joints together in a well bore) to each disc and insert the "pin" (threaded) end into the collar, so they could be disassembled when not in use. It would also give a bit of adjustment for uneven floors.

Here's a picture of one close up:
