Paul,  I am going to build a Kiss Cruiser Schertz Beam engine mount.
Could you determine in your CAD program if the 32.5 inch (overall) beam
will clear the cowl?  BTW it does clear the Tailwind cowl by 1.5
inches.  Most cowls are more spacious than the TW.   Do you have a
drawing on hand of the Long EZE that you could check for same?   If it
fits the Kiss and the Long EZE, then it will fit anything.     Thanks,
Jerry

I don't have a good 3D model of the Cruiser cowl. Best thing I could do is mock
it up with a piece of wood and see if my cowl fits over it. My guess is it would fit.
One point. The Schertz beam lowers the position of the rubber bushings relative
to the engine compared to the motor plate method so it might get them down in
the area of the cowl that starts to curve under the engine. I assume that Bill
Schertz's cowl fits over his Schertz beam. In that case it should fit. Bill
is that true?

BTW there are two cruiser cowls both Bill Schertz and I have the early short ones
as I recall. I think there is a later longer one. Charlie what is the distance
from firewall to prop flange on your Cruiser cowl? Also Charlie check these
Cruiser firewall mounting points dimensions carefully. Since Charlie is not
that far from you perhaps he can bring his cowl down.

I don't have much on the Long EZE. I'll check.

I have never attached the cowl to the fuselage so I can't give you a measurement on the plane without a bunch of work (cut out area for front gear).  The joggle on the front where the cowl mates is at the firewall.  So what I did was lay the cowl upsidedown on the shop floor and measure it from end to end.  It measures exactly 36 inches.  This should be extremely close to the distance from firewall to prop flange at the beltline.

I did cross check the mount point dimensions versus the drawing I gave to Jerry (a cleaned up version of what's on your web page, Paul).  To the extent I can determine, they are exact.  However, the locations are only marked with 1/8 inch holes drilled through the firewall.  These do not have to be exact as the area that has been reinforced on the interior side to hold the mounts is substantial.  My guess is that the location could drift by 1/4 inch and still be OK.

Bill, what do you think?
