❏ 10. Mark the center of the cowl mounting blocks
onto the fuselage.
❏ 11. Tape the cowl to the fuselage. Drill 1/16"
[1.6mm] holes through the cowl and into the cowl mounting blocks 1/4" [6mm] from the front edge of the fuselage.
❏ 12. Remove the cowl. Enlarge the holes in the cowl
only with a 3/32" [2.4mm] drill. Mount the cowl with eight #2 x 1/2" [13mm] screws. Optional: The same as was done for the aileron and flap hatches on the wing, bevel the opening of the cowl mounting screw holes and mount the cowl with #2 x 3/8" [9.5mm] flat head screws (not supplied).This makes for a neater appearance, but requires a little more skill to countersink the holes without over-enlarging them.
❏ 13. Now that the seams on the inside of the cowl
have been “glassed” and the cowl has been mounted to the fuselage, it is time to smooth the outside with filler. Automotive filler such as two-part polyester Bondo is highly recommended, but don’t build up too much at once or it will take a long time and be difficult to sand. Use an expired credit card or something similar to apply filler where needed, allow to harden, wet sand, and apply more filler as needed for a smooth appearance.
❏ 14. Mount the cowl to the fuselage and blend the
two together by sanding where necessary.
❏ 15. Apply a coat of primer to the cowl and allow to
dry. Reinstall the cowl and cut all openings necessary for the glow plug, needle valve, engine exhaust, etc. One method for locating holes is to make a template from a piece of cardstock. Tape the cardstock to the fuselage, then mount the cowl. Mark the hole in the cardstock onto the cowl, then remove the cowl and cut the hole.
❏ 16. Cut the opening in the bottom of the cowl for the
nose gear. If you’ve installed retracts, be certain there is adequate clearance to allow for right and left steering.
