the bottom edge to the top of the fuselage side and the
3/16" [4.8mm] balsa stick. Tape the sheet in place while the
glue cures.
❏
45. Wet the outer side of the sheet with warm water and
ammonia. This will help you to bend the sheet to the aft
turtle deck shape. Once the sheet has conformed to shape,
apply CA to the edges of formers F4-A to F6-A and to the
top fuselage spar. Hold the sheeting in place with tape or
rubber bands until the glue has cured. When the sheeting
has dried, sand the ends flush with the formers.
❏
46. Follow the same procedure to glue the sheeting on
the other side of the aft turtle deck.
❏
47. Locate a 1/16" x 3" x 18" [1.6mm x 76mm x 457mm]
balsa sheet. Use the preceding sketch to cut the sheeting
for the forward sheeting. Use the same procedure as
described in the previous step to glue both sides of the
forward turtle deck sheeting. Once the sheeting is glued in
place and dry, sand the ends flush with the formers.
❏
48. Cut a piece of leftover 1/16" [1.6mm] sheeting to fit at
the canopy base between F3-A and F4-A. Glue it in place
with CA and sand it flush with the sides.
❏
49. Mark the center of the fuselage top at F6-A. Make two
more marks on each side 1/8" [3.2mm] away.
