2 Beaver Instruction Manual
33.
Install the Fuselage Top (roof) to Bulk-
heads 3 and 4. Glue first to Bulkhead 3
and the balsa brace while lifting up on
the aft end of the Top so the Top re-
mains tangent to the airfoil shape on the
fuselage side (see photos). Once the
glue has grabbed Bulkhead 3, push the
top down to adhere to Bulkhead 4.
34.
Tape all the remaining bulkheads in
place, etched labels forward. Check for
straightness by putting the wing tube
and the horizontal stab in place (if you
have built the horizontal stab). If the
stab isn
’
t parallel to the wing tube, ad-
just the tape to apply twisting pressure
and check again. Once satisfied with
the alignment, apply CA to Bulkheads 5
through 8, gluing them into place.
35.
Remove Bulkhead 9 and the Canted Bulkhead from the fuselage.
36.
Install the 3mm blind nuts from the tail wheel kit onto the Tailwheel Mount Doubler using epoxy.
37.
Glue the Tailwheel Mount Doubler, Bulkhead 9, and the Canted Bulkhead into the fuselage. Note
the Canted Bulkhead needs to have a small relief cut for the fuselage side to set properly in place.
See photos. Also note the top of Bulkhead 9 is slightly curved, so you will need to form the top
around that curve.
38.
Install the pre
-
formed 2.5mm sheeting on the lower fuselage corners. This sheeting has been formed
to the proper radius at the factory to make building easier. Start with the sections on the forward
fuselage between bulkheads 2 and 4.
a.
Cut a piece of the curved sheeting to 14 ½
”
long (368mm). This is a rough length which will likely
require slight trimming at the end for a proper fit.
b.
Cut holes to allow the sheeting to fit over the float mounts. Take your time doing one hole at a
time. A spray can, roll of tape, or piece of
2”
PVC pipe (50mm) can be used to help mark these
holes on the inside of the sheeting.
i.
The first hole will be about 3
3/8”
(87mm) back from the front end, and about
7/16”
(12mm)
from the edge.
ii.
The second hole will be about 7
1/16”
(179mm) from the front end, and about ¾
”
(19mm)
from the edge.
c.
Trim the sheeting to width. Use one edge as a baseline and trim & sand to fit the other. Take your
time to achieve a good fit. Note there is a taper at the front end between bulkheads 2.5 and 2.
d.
Glue this sheeting in place.
