Paul--

Here are the rest of the details with a side view of our engine mount
project and some plans of the original mount depicting the tricycle gear
components. All the tubing has been removed except the lower truss
assembly for which I have a jig to place in its proper position. With
the engine where it is with CG at 22" from firewall and the bottom of
the block 7.75"  (8" without the .025 aluminum plate) above the
bottom line of the _30.5_" X 16 " rectangle formed by the hard points on
the firewall (previous picture of actual firewall) I hopeful an engine
mount design utilizing a *shertz beam* can be designed. I already have
the mock-up firewall configured to give me a 3 degree downward and 3
degree offset to the left.

Appreciative of your efforts--Tom Chapman

-----------------------------------------
OK Tom the side view plans are what we need. We have a good start
on those with this first one. Is it possible to scan them in pieces
until we get to the prop flange?

Do you have the stock cowl?

If so what is the distance from the firewall to the prop flange
opening on the stock cowl? It should be about 40 inches plus or minus
5 inches or so.

We may have to move the engine forward a bit to clear the nose gear.
No big deal. I would mock up the nose gear with cardboard tube
if you don't have it yet? We might not be able to use the strut
rear engine mount as it looks like it will conflict with the
nose gear. Not to worry! We can use our new universal rear motor
mount instead. Down thrust is then adjustable with shims.
