O.K. How precisely is it 15/16"? Do you have a micrometer to
measure it precisely? I would expect it to be pretty precise, as it
looks to be surface ground to dimension.

Are there any markings on it other than the end markings?


I was planning to use the micrometer at work today but it wasn't available,
I should be able to use it in a day or two. There are no markings on it
other than on the visible end. One more thing about it that I don't think
that I mentioned before, it's made from a single piece of metal.
