Important
: Make sure to use enough epoxy to glue
the fin securely to the fuselage. Not using enough
epoxy may result in a poor bond between the fin and
fuselage, which could cause the fin to loosen in flight.
18. Mix a 1/3 ounce (10mL) of 30-minute epoxy. Apply
the epoxy to the exposed wood at the bottom of the fin as
well as to the fuselage where the fin will come in contact
with the fuselage.
19. Slide the fin into position. Use a paper towel and
rubbing alcohol to remove any excess epoxy from the
fuselage.
Important
: If there isn’t a fair amount of epoxy
to remove, you have not used enough to glue the
fin in the fuselage. Remove the fin and apply more
epoxy so there is a fair amount of epoxy oozing
out when the fin is inserted in the fuselage.
20. Check the alignment of the fin to the stabilizer.
Position the fin so it is perpendicular to the stabilizer. Use
low-tack tape to keep the fin in position.
Align
Perpendicular
21. After around 25 minutes, before the epoxy fully
cures, carefully remove the tape from around the fin. Pull
the tape away from the fuselage, being careful not to disturb
the position of the fin. This will allow the epoxy to flow out
slightly, leaving a fillet between the fuselage and fin. Allow
the epoxy to fully cure before disturbing the airframe.
22. Remove the rudder from the fin, leaving the torque
rod in the fuselage. Place a T-pin in the center of two hinges.
Insert the hinges into the rudder as shown.
