Any suggestions for sensible knots that would allow me to a) tighten the loop around the screw at the bottom post-hoc and b) adjust the length of the cord post-hoc (but it holds the weight of the boards + books)?
Doesn’t that get in the way while sleeping? Don’t you ever knock it down?
What I would do is connect it the opposite way round. So that it folds down, not up. Give it a little leg that folds out when you pull it up.
The leg could be done in a few ways. But I would prefer it so that it is connected to the table top’s underside on a hinge. So, when the table is folded down the leg is tucked behind it, and when you pull the table up, the leg “drops” down and upright.
Maybe reverse the hinges so it swings down and out of the way. You might hurt yourself on the board sticking up when sleeping.
You’re going to find that edge and/or corner one night and you’re not going to have a good time.
Why not have something moveable underneath to support it? That string seems impractical in general.
Yeah a piece of wood the same thickness as the shelf on a hinge attached to the frame could swing out and support the shelf. When folded in it would be the same thickness as the shelf folded up.
Perhaps you could try a farrimond friction hitch on both ends? It fits a+b and it has a quick release
