Had the idea of folding the table up (around an axis through the cog, more or less) too. Folding the rails is not so promising, but the whole table could be swept up. Or lifted and stacked in a rack (Ryan, pls design a mostly printed fork lift!). I got a simple large plywood board now that I enforced (not really necessary for 21 mm thick birch playwood) with 40 by 80 (mm²) timber beams. But that frame is a good base for legs or hinges or… If the room is high enough, one could also winch up the whole affair to the ceiling.
More on my table real soon.
