My Truth Tool is not accurate to 0.0001"(one ten-thousandth). But I have no doubt it is at least accurate to plus or minus 0.001" (one thousandth) which to my mind is adequate for my purposes.

I am glad though that you airplane guys are so anal retentive about accurate measurements. Mechanical failures at 30,000 feet while traveling 500 mph could really ruin a day.



I am glad to be here.
