JIGGING OF THE FUSELAGE
.....
In this step, you will want to trim for final fitting the
following bulkheads: FS175, FS120, FS94, Seatback Bulkhead, and
Firewall. All bulkheads, including the firewall, fit inside the shells,
so that they rest against the inside skin of the shells. Begin by
drawing BLOO down the bottom fuselage shells, forward and rear. Check
the squareness of the lower forward fuselage shell where the firewall is
located. It may be necessary to trim the forward edge of the lower
forward fuselage shell to make the firewall set square. (i.e.
perpendicular to BLOO and WL15). For now, you may assume that a level
placed across the longitudinal split line at the firewall attachment
point is correct for leveling the fuselage laterally. Don't forget that
the firewall fits inside the shell. The FS120 bulkhead location is
nominally at FS120 for the forward face, but is uncritical and can be
moved plus or minus 1 inch for best fit. The FS94 bu1khead should not be
trimmed until after the Seatback Bulkhead. The FS175 bulkhead aft face
is located at FS175.

The location and angle of the seatback bulkhead is the prime
consideration for comfortably accommodating different pilot sizes. If
the primary pilot is over 616" tall or less than 5'5" tall, then Quickie
Aircraft Corporation should be contacted for assistance in creating a
comfortable fit. Basically, moving the break point in the Seatback
Bulkhead lower allows the
