9.
Tack cement the rudder to the fin and then
transfer the hinge locations onto the rudder. Do
not sand.
10.
Referring to the plan, flat sand the fin/rudder
assembly and the stab/elevator assembly,
rounding all outer edges except the bottom and
lower 2” of the fin leading edge. Take care not
to sand away the hinge locations.
Sand the elevator tips to blend with the stab.
Holding the CGM centerline marker at an angle,
so that the pegs touch the wood, lightly pass the
marker back and forth so that the point scribes
a line, marking the hinge locations on the fin and
the stab.
Again using the centerline marker, mark a cen-
terline along the entire leading edge of both the
elevator and the rudder.
12.
Using an awl or similar tool, make a pilot hole at
the hinge locations on the fin and the stab.
Move the stab T.E. close to the edge of the table
and, using 1/16” scrap ply as a shim, make sure
the T.E. is level and steady.
Carefully drill 1/16” holes for the hinges, as
shown above.
8.
Referring to the plan, mark the hinge locations
on the fin T.E.
After gluing the fin and rudder pieces, allow to
dry before continuing.
11.
Carefully separate the stab from the elevator
and the fin from the rudder. Gently sand to
remove any rough spots from tack-cementing.
