Next message: Jared Sherman: "Re: Follow-up to Jared's post, RE: levels"
Meant to send this to the List, but apparently sent it directly to Ken:
My six inch, model #98, Starrett level came with a card containing the
following information:
The main vial was ground. (there's also a small cross-level vial).
Graduations on the main vial are at 1/10 inch intervals.
A bubble movement of 1/10 inch indicates an elevation of .005 inches per
foot.
My experience is that it's easy to level to the half-division, or .0025 per
foot.
