Wow, that's like a 4-handed caliper...gotta take into account the curvature of the earth ;-P

Imagine the temperature related error at full scale.

Hard to imagine trying to measure by your self with them extended to the full 2 meters

[Harvey Melvin Richards]

My largest Mitutoyo's only go to 30", so I'm feeling rather inadequate now.

[McDesign]

Yes - wonder if it's any particular alloy to minimize that?

I don't get the measure of that. WTH. Did Jack carry that back to this planet?

We had identical 72" Kanon in a shop; to match paper handling rollers OAL. Greatly simplifies setting bearings in solid end-frames. Temperature control was not considered, it was stored boxed in same room as machinery, normalization attained continually. Exact length was less important than equal length.
