❏
Lay out the location of the nose gear bay framing on the aft face of frame No. 1. The top
of the nose gear bay (or the floor level) is at W.L. –420. Update your insulation template.
❏
Lay out the framing for the exhaust port and transfer this to your insulation template. The
exhaust port framing consists of 15x15 spruce pieces in a “picture frame” around the
exhaust port as shown in Figure 21. The upper members of the box between frame No. 1
and 2 will be installed at an included angle of 102°. Since you will have a similarly
matching 78° on the front face of frame No. 2, make the two strips at once by ripping a
piece of spruce with the table saw blade set at 12°. Because of the way the box is
constructed, this angle does not match the angle on the bottom—where the exhaust port
shield will be installed.
