    This sounds like it may fall under the heading of metrology . If so, it’s a little outside the comfort zone of most of us here. Still, there are a few guys who might have a crack at it…

    Your link to a diagram requires one to sign in, so some people won’t see it.

    What is the vertical dimension and what is the tolerance on how plumb it must be?

    what kind of tolerance are you expecting? I would think first setting a base point below then using a laser or optical plummet to plumb the line.
