Step 2-12
Step 2-14
2-11. DO NOT GLUE - Slide the aft centering ring (ring F)
over all three motor tubes, and rotate the tubes so that
the engine hooks align with the notches in the aft ring,
and are all facing the same direction.
2-12. Rotate the latch assembly, so the latch is facing
away from you. Apply glue to the interior of the three
holes. Quickly install the front of the motor mount tubes
in the latch assembly centering ring, Press the tubes all
the way into the front centering ring and get the tubes as
square as possible.
2-13. Once the tubes are secure at the latch assembly,
apply glue at the 5/8" (16mm) marks of all tubes and slide
the aft centering ring into place.
2-14. Apply wood glue to the joints between the centering
rings and motor tubes, then form llets with a nger tip.
Allow the removable mount to dry entirely before install-
ing in a rocket.
Adjusting Mounts for Correct Fit
To adjust the t of the removable mount, the tabs may
need to be led down somewhat. This compensates for
slight inaccuracies in both the xed mount and remov-
able mounts. To test, insert the removable mount into the
rocket and rotate it until the tabs on the latch drop into
the slots in the xed mount. Rotate the removable mount
clockwise to latch. If the removable mount refuses to
rotate or is overly stiff, take the mount out and use a at
needle le to remove material from the aft side of each
of the tabs (as shown here with the 3x24mm mount).
Repeat this process of testing and removing material until
the mount rotates and latches without binding
