21, D GLUE THE CHIN BLOCK TO THE FUSELAGE
With the fuselage still at 90 degrees to the board
and over the plans, align the chin block to the back of bulk-
head #2 and glue the chin block to the fuselage.
*0n the Sportster 20 make the rear end of the block even
with the wing saddle openings in the fuselage sides.
22. D ADD THE BALSA BOTTOM SHEETING
Remove all pins from the inside of the fuselage.
Cut and glue on the bottom sheeting. For conventional
gear, leave the last section of sheeting off until the tail
wheel is installed later. When the glue is dry, remove the
fuselage from your building board and trim and sand the
bottom sheeting to shape.
23. D CUT OUT AREA ON REAR HOLD DOWN FOR
AILERON TORQUE ROD CLEARANCE
Align the fuselage over the wing and draw refer-
ence lines on the wing along both sides of the fuselage.
Mark the locations to be relieved on the rear hold down
plate for the aileron torque rod clearance. Remove the
fuselage and cut away the area on the hold down. Check
your work by placing the fuselage on the wing and operat-
ing the torque rods. A Dremel tool and router bit or grind-
ing drum or a coarse wood rasp works well for this step.
24. D PREPARE TOP FORMERS 1A THROUGH 6B
Prepare the fuselage top formers by numbering
them to match the plans. Mark the locations of the stringers
on formers 3B and 6B by referring to the plans. Glue former
3B to the back of 3A. Glue former 6B to the front of 6A.
Draw the location lines for the cockpit floor on the back of
the dash and on the front of the 3A/3B assembly.
