Ok, Dale, understand why you want it
done "right". Yes, the "Plugs Up" orientation works well for me and
provides lots of room on the side for induction system, puts the exhaust on the
bottom which makes the header design simpler. Also means if the fuel
system leaks, it won't drop straight down on the hot exhaust.
Good luck. I built a test stand using
my engine mount and then transfer the same mount to the aircraft - no I did not
weld it up got somebody who knew what they were doing to do
that {:>)

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.
