❏
Glue the trailing edge ribs for Sta. 1, 2, 3 and 4 in place. Scuff-sand the plywood before
gluing.
❏
Fit the two spar doublers to the aft face of the spar. These are shown on Drawing No. 411,
Section B-B.
Figure 7
❏
Fit the Sta. 0 diagonal rib. This will require that you also cut the two spar doublers to an
angle to match that of the diagonal rib. Note that this angle is also the same as is used in
the following step. See Figure 7.
❏
Fit the two 4mm birch plywood doublers installed under the channel-nuts at Sta. 0. Two
pieces of 2mm birch plywood may be glued together to make these pads. Drill through
these pads for the channel-nuts.
❏
Glue the spar doublers in place.
❏
Hold the diagonal rib in place and trace the inside surface of the spar doublers on the
upper face of the rib. This is for varnishing.
❏
Fit the 1.5mm plywood skin on the aft face of the spar doublers. Note on Drawing No.
411, Section B-B, that a 1/8ӯ vent hole is drilled in this skin.
❏
Varnish the interior surfaces of the spar between Sta. 0 and 1, the forward face of the
1.5mm plywood skin and the upper forward face of the diagonal rib. The gluing surfaces
should be masked off, and you only want to varnish those areas which will not be glued.
❏
Glue the 1.5mm plywood skin on the aft face of the spar doublers. Scuff-sand the plywood
before gluing.
❏
Glue the Sta. 0 diagonal rib in place. Scuff-sand the plywood before gluing. If you wish,
the following step may be done at the same time.
❏
Glue the two 4mm birch plywood doublers in place. These are most easily clamped by
using the channel-nuts and the hinge. If you are using epoxy glue, the channel-nuts may
be bedded down in epoxy and installed. If you do this, first ream the screw holes for the
channel-nuts with a No. 27 (.1440ӯ) drill. Scuff-sand the plywood before gluing.
❏
Glue the trailing edge strip in place. See Figure 8.
