Okay, I admit I'm taking the easy way out. I haven't done an
exhaustive search of the archives. Is there an easy way to
ascertain the eccentric shaft centerline, for purposes of designing
an engine mount? I've decided I want to try a plugs-up mount for
my test stand. Some things might be easier to fit in, using that
orientation.

So far, only two strategies have come to mind: take the eccentric
shaft out, and replace it with two apertures; or machine a pointed
mandrel which can be bolted to the pulley flange.
