PRELIMINARY TRIMMING OF THE CANOPY CUTOUT
.....
In order to provide access to the interior of the cockpit, you will
need to digress for a moment and make a fitting of the pre-trimmed canopy
to the upper for ward fuselage so that a cutout can be made in the upper
forward fuselage.
.....
The forward face of the firewall is FS14.0; the forward face of the
seatback bulkhead is FS78.0. Therefore, measure 64 inches from where the
forward face of the firewall will be located along a WL to establish the
aft edge of the canopy. Next, establish a preliminary BLOO line down the
forward upper fuselage she 11 .
.....
Drape the canopy, which is sent to your pre-trimmed to rough shape,
over the forward fuselage. Even up the sides by measuring the distance on
each side up from the longitudinal fuselage split line and adjusting the
canopy until the distances match. Also, check for skewing.
.....
Now, take a marking pen and draw a line around the outline of the
canopy where it touches the fuselage. Some trimming of the canopy-may be
required to make it fit flush against the fuselage shell.
.....
Remove the canopy and make a cut around the upper forward fuselage
shell at the line. To be conservative at this point, you may wish to not
cut quite all the way to the line, and then final trim the cutout later.
All you are trying to do here is to gain access to the inside fuselage
and to establish a rough fit on the canopy.
