only complication is that upper wing skin makes it difficult to staple the skin to the lower side
longeron. This is a very good reason to start at the bottom side longerons, where you can use
small C-clamps, tilt the staple gun and shoot one-legged staples, and use small brass nails through
nailing strips. You will then have all the heavy work of pushing and clamping to do at the top,
where you can easily work on things.
You may want to consider bracing the centersection of the fuselage so that the sides don’t bow
inward when you bend the plywood. Most builders don’t do this, but if you want to be extra
careful, then you can just jam some cut-to-exact-width boards across each frame to ensure that
nothing moves.
❏
Install the blocks required for the canopy track. See Drawing No. 107 or 107A. If you are
going to install the left hand throttle modification, the forwardmost block should be solid
to fuselage frame No. 4. See Drawing No. 157.
❏
If you are going to install the left hand throttle modification, install a 50x50 spruce
triangle on the forward face of frame No. 4 on the left side of the airplane. See Drawing
No. 157.

❏
Fit the interior cockpit skins between Sta. 3 and 6. This is ordinarily done in separate
pieces with a scarf joint at each fuselage frame and so that the skins will be installed from
the aft working forward. Install corner blocks and trace the outlines of the frames for
varnishing.
