❏
Drill the 1/4ӯ hole for the tail light wires.
❏
If necessary, trim the end of the spar as shown for P/N 415-2.
Main Stabilizer Spar
❏
Review Drawing No. 406. If your spar has been made to the older drawings, you should
add an extra block of spruce at Sta. 1 on the right side. This is so that you can epoxy the
trim tab tube in place.
❏
Glue plywood on forward face of the spar at the center. Note that the plywood extends
out to B.L. 90. The reason for this is that the Sta. 0 ribs will be glued to the forward face
of the spar, and it seems to be neater to glue to a plywood surface. Scuff-sand the plywood
prior to gluing.
❏
Glue plywood pads on the forward and aft face at Sta. 5. The plywood pad on the aft face
is to create a “level” surface for the hinges. Because thinner plywood is used on the
outboard ends of the spar, the hinges will be moved forward slightly. Probably this is
academic, but since you will need to increase the thickness of the spar to match the grip
length of the bolts, it seems to be a good idea. Scuff-sand the plywood prior to gluing.
❏
Draw spar centerline on forward and aft face of the spar.
❏
Draw aircraft centerline on forward and aft face of the spar.
❏
Drill the .62ӯ hole at Sta. 1 on the right side.
❏
The trim tab tube is flared at the aft end (so that it will not cut and chafe the trim table
control cable) so you may now sand a “countersink” to match the tube.
❏
Epoxy the small piece of aluminum or stainless steel on the bottom of the spar at the
centerline (this is the elevator stop, see Drawing No. 402, Section B-B). Any epoxy may
be used, but if you can get it, 3M 2216B/A epoxy is one of the best glues for bonding metal
to wood. You can get it in 2 oz. kits from your local 3M distributor—there’s one in every
major city.
❏
If necessary, trim the end of the spar as shown for P/N 403-1.
Forward Stabilizer Spar
❏
See Drawing No. 406. Draw spar centerline on forward and aft face of the spar.
❏
Draw aircraft centerline on forward and aft face of the spar.
❏
Install plywood disk at aircraft centerline and drill 3/8ӯ hole for the elevator control
cable. Scuff-sand the plywood prior to gluing.
❏
Drill the .62ӯ hole at Sta. 1 on the right side only. This is for the trim tab cable tube.
