Step 39:
Thread the 48” x 1/16” fiberglass
rods half way through the slices as shown.
Step 40:
Find spanwise index marks on
wings and slice 1/8” deep along these lines
Make 8 spanwise
slices-- two on
each wing surface
Step 35:
Slice all the way through fuselage
at the marks as shown.
Step 31:
With wing LE in position, transfer
wing spar locations to fuselage as shown
Step 32:
Mark the rear of the wing location
on fuselage as shown
Step 33:
Measure and mark the center
location for the wing rear position
Step 34:
Connect the spar location marks as
shown
Step 36:
Poke and slice carefully through to
the other side as shown
Step 37:
Mark centerline of fuselage as
shown for front and back pieces
Step 38:
Sand the rods even with the
fuselage edge as shown
Do for both top
and bottom wing
surfaces (on both
sides of fuselage
also)
An awl or long
wire will help
determine the
edges where spar
rods will reside
Install
all 4
spars
You’ll use these
guides later for
alignment of wing
and tail parts to
fuselage
