 J-3 Cub Construction Project Session #23

23 J-3 Cub Stab Construction
 

Yesterday afternoon I laid up the stab structure. Mike Midkiff recommended that the stab and elevator 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. Shaping the two 1/8" square splines required a lot of time because their collective required drying time. I used a 1/8" square main spar and laminated a 1/16" X 1/8" medium hard piece out two bays as seen below. I also put two lightening holes in the center section 1/8" piece. Two short 1/8" pieces were drilled and glued in front of the 1/8"square spar in the third bay for the scale bracing wires......................Tandy
