They proly spec'd it at 68 deg and were then going to inspect it at

Which makes sense. g


The idea, of course, is that you inspect all of the mating parts in an
assembly at a specific temperature.
Differences in coefficients of expansion aside - something that does have to
be accounted for in many cases - the parts will be at the same temp. at
assembly. I'm sure you have heard of "Standard Temerrature and Pressure" in
your wanderings G
