Anyone have an idea on who makes a ONE PIECE 8 foot straight edge?


There are 8-ft levels out there. reasonably priced, too.
Hard to find a straighter edge than that.

Not really. Levels are a bit concave to bias them towards
resting out at the ends.

???
Are you saying that levels are hourglass shaped?
All I can say is that I've NEVER seen one like that and would throw it out
if I did..
I'd also say that since most modern 8' levels are made from aluminum
extrusions, they are a constant dimension along their length.
