Sheet the Lower Half of the Fuselage

1. Use a sanding bar to sand the stringers flush with the
formers.
2. Trim a 1/16" x 3" x 30" [1.6mm x 76.2mm x 762mm]
balsa sheet to fit between F1A and F6A. Note: Do not glue
the forward lower sheeting to formers F6D, which is glued
behind F6A. The sheeting should be glued so that it only
covers the bottom half of the top stringers. Cut a second
sheet to fit on the other side. The remaining 1/16" [1.6mm]
balsa sheet will be use on the aft end of the fuselage.
3. From the remaining sheeting cut in step 2, trim and
glue the aft lower sheeting between F6D and F9.
4. Trim and sand the lower sheeting flush with the bottom
of the formers and wing saddle sheeting.
5. From the 1/8" x 3" x 30" [3.2mm x 76.2mm x 762mm]
balsa sheet, cut the aft bottom deck as shown on the fuse
plan, and glue it to the bottom stringers and formers.
