Thanks Ed,
If all it was *ever* going to be was just a test stand, I'd agree
about the precision. The test stand is as accurate a model of the
COZY firewall, dimensionally, as I can make it (same template). If
this works out well, then I'll be duplicating the mount for the real
thing - except I'll send that one out to be welded by a certified
welder. If it doesn't, then I hope CCI gets caught up on the
backlog before next fall (2007).
BTW, most of my ideas for implementing "plugs-up" came from
the photos of your installation.

Boy, seems like a lot of
work either way. I am not certain you need that kind of accuracy
(particularly for a test stand). I think I would determine the center
of the e shaft (pretty easy to do with the flywheel nut on) and perhaps
a bit harder on the pulley end (depending on whether a stock or after
market pulley) and then hang the engine and use a carpenter's square
(or something similar) attached to your firewall (or front end)
wherever you want the e shaft center line to be. Then align the engine
until the flywheel nut center line and pulley center line with your
reference (T square point).

[FlyRotary] Engine alignment
Hi All,
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.
