7. Use the 1/2" [13mm] holes to align the die-cut 1/8"
[3mm] plywood rib doublers R5A with ribs R5. Glue in place
with medium CA. There will be an offset built in just like in
the previous step.
❏ ❏
8. Test fit ribs R2 through R10 on the main wing spar
and web. DO NOT install R4 until instructed to do so.
❏ ❏
9. Test fit the die-cut 1/8" [3mm] balsa TE Jig. Insert the
wing ribs into the slots on the TE jig and align with the plan.
❏ ❏
10. Test fit the die-cut 1/8" [3mm] balsa LE Jig. Insert the
wing ribs into the slots on the LE jig and align with the plan.
❏ ❏
11. Once you've finished test fitting and are happy with
the fit, begin gluing using thin CA. Weigh down the TE to
keep it flat on the work bench. Starting at R2, glue the ribs
first to the TE and then to the LE. Ensure each rib is pressed
all the way down into the TE slots and the LE is pressed all
the way down onto each rib. After the LE jig and TE jig have
been glued, glue the center spar and center web into place
using thin CA.
❏ ❏
12. Test fit R1, the die-cut 1/8" [3.2mm] plywood
forward dowel support (FDS) and the die-cut 1/8" [3.2mm]
plywood aft dowel support (ADS).
❏ ❏
13. Make sure the bottom aft wing spar is pressed all
the way up into the slot in R1 and glue in place.
