❏ 11. Use 6-minute epoxy to glue the die-cut 1/16"
[1.6mm] plywood lower gear supports doublers (LGSD)
to the inside of both die-cut 1/8" [3.2mm] plywood lower
gear supports (LGS). Align the notches and the forward
and aft ends. Be sure to make a left and a right lower gear
support assembly.
❏ 12. Position the lower right fuse crutch on the upper right
fuse crutch. Mark the front of the lower fuse crutch even
with the front of the upper fuse crutch and trim to length.
❏ 13. Drill holes to match the size of the outer pull-pull tail
wheel steering cable guide tubes at the punch marks in the
die-cut 1/8" [3.2mm] plywood formers F-6C, F-7C and F-8B.
❏ 14. Test fit the lower fuse crutches to the upper fuse
crutches. Place a straightedge against the face of both
crutches to check that they fit together flush and the joints
between the crutches are tight. Test fit the die-cut 1/8"
plywood formers F-6C, F-3B and the crutch bottom (CB)
on the lower fuse crutch.
❏ 15. When satisfied with the fit of the lower crutch, use
30-minute epoxy to glue the lower crutch to the upper
crutch. Also use epoxy to glue F-3C, F-6C and the crutch
bottom into position. Use plenty of clamps to hold the
upper and lower crutches together until the epoxy cures.
❏ 16. Hold a straightedge against the front of former F-2
while gluing the die-cut 1/8" [3.2mm] plywood former F-2B
to the lower crutch, crutch bottom, main stringer and
crutch stringer. F-2B. Also, make sure F-2B is positioned
at the back of the slot in the crutch bottom.
❏ 17. Glue the die-cut 1/8" [3.2mm] plywood formers F-4B
and F-5B to the lower crutch, crutch stringer and
main stringer.
❏ 18. Insert the die-cut 1/8" [3.2mm] plywood former F-6D
into the slots in the lower crutch. Note that the aft bottom of
the lower crutch will need to be trimmed slightly to clear the
stringer notch in F-6D. After trimming the lower crutch glue
F-6D to the lower crutch, crutch stringer and main stringer.
❏ 19. Glue the die-cut 1/8" [3.2mm] plywood formers
F-7C, F-9B and F-10B to the main stringers and the front
of their respective formers.
❏ 20. Test fit the lower gear supports, assembled in step
11, over the upper gear supports, checking that they fit
