BALL LINKS FOR FRONT DOOR HINGES
❏ ❏ 7. Cut 1/16" [1.5mm] from two more nylon ball
links. Mount each ball link to another TYPE A and
TYPE B door hinge. These door hinges will be for the
front of the gear doors.
❏ ❏ 8. Prepare two “TYPE A” nacelle hinges and
two “TYPE B” nacelle hinges by mounting an 0-80
ball link ball in the bottom hole of each hinge with an
0-80 nut and a drop of threadlocker on the threads.
❏ ❏ 9. Snap the ball link balls of the nacelle hinges
onto the ball links on the door hinges as shown.
As best as you can, get the bases of the hinge
to lay flat on the door and on the nacelle cover.
Make sure the glue press up and fills the holes
of the mounts.

❏ ❏ 10. Use coarse sandpaper to roughen the bottom
of each hinge base so glue will adhere. Test fi t the hinge
assemblies to the doors and nacelles—each hinge
assembly should be in the location and orientation
shown. If necessary, adjust the length of any of the
ball links by cutting them shorter so the hinges will rest
fl at, or nearly fl at, on the doors and nacelle.
❏ ❏ 11. Use epoxy mixed with milled fi berglass or
micro balloons to glue each door hinge to the doors.
After the epoxy has hardened glue each nacelle
hinge to the nacelle.
❏ ❏ 12. After the epoxy on the door hinges has
hardened, remove the masking tape and open
the doors.
❏ 13. Hinge the doors to the other nacelle the
same way.
