Would a spring itself work instead of a flat piece?


No, but again, we studied that. No way to meet the hazard requirements
and also fit it into the available space.

Hey again Lloyd,

I don't know what it is called, but this sounds like the perfect job
for the form of a tape measure blade, where when straight, the "blade"
is concave (or is it convex??) across its width and wants to stay
"straight", and flat when coiled. I haven't seen one for quite some
time, but there used to be short rules say 1" wide of 24 or 36" length
that were "loose" and not inside a tape measure that worked that way.
