@Lascauxcaveman that's basically what I was thinking, only more like this - there's 7 pairs of bars here taking up less than the width of two bars, there's even a rando drop hiding in there happy as a clam. I think something like this will work, maybe with a closet rod or 1x2 spaced 2-3" off a wall? I just need to fine-tune, I've got the scrap lumber for it.

Unfortunately, I'm below grade in the basement shop - I suspect a lot of us are subjected to the basement - so I can't necessarily run around drilling holes in foundation walls all over the place. Gonna hafta find some wooden wall space. Maybe over the shop bench.
