J-3 Cub Construction Project Session #19
J-3 Cub Rudder
Construction
I had a little time this morning before my hair
cut, so I decided to lay up the fin/rudder structure. Mike Midkiff recommended
that the fin and rudder be made a single unit structure as shown below.
Further Mike recommended that the structural members be 1/8" thick, but only
1/16" wide. The preshaped spline is 1/8" square and I also used two 1/8"
square pieces, one for the vertical rudder spar and one to simulate the
division between the rudder and the fin at the top of the structure. In
addition, you can see the piece of 1/8" sheet that was shaped, drilled, and
glued in front of the 1/8"rudder post near the top for the scale bracing wire,
which will of course be thread...............Tandy
