ROCKET.
When all epoxy has cured, insert the av-bay back into the “holder” to
confirm all attachment points line up. Upon confirmation, remove the av-bay from the
holder, stuff the Kevlar bridles inside the tube and go to the next step.
With the above holder and the upper airframe section, insert the holder into the upper
airframe 18.5” from one end and place a mark around the inside of the airframe next to
the av-bay holder.
WITHOUT MOVING THE HOLDER,
make a mark around the inside of the airframe
next
to the other end of the av-bay holder. Now remove holder from airframe. You are now
going to place a ring of epoxy, one inch wide, on the
INSIDE
of each mark you drew
inside the airframe. Insert the av-bay holder inside the airframe (it doesn’t matter which
way) until it is in position
INSIDE OF BOTH MARKS drawn
previously.
IMMEDIATELY, WIPE UP EXCESS EPOXY, BEING CERTAIN NONE GETS
ON THE KEVLAR BRIDLES OR THREADED INSERTS.
Let the airframe lay on
its side occasionally rolling to prevent the epoxy from “pooling”. REMOVE ALL
EXCESS EPOXY. Allow to cure.
Standing the airframe on one end, apply a small epoxy “fillet” to the av-bay
holder/airframe joint allowing epoxy to run into the thin gap between the smaller outside
centering ring to the larger interior ring.
BUT NOT ON THE FACE OF THE
SMALLER CENTERING RING! DO NOT ALLOW ANY EPOXY TO
MIGRATE TO THE THREADED INSERTS OR INTO THE 3.9” INTERIOR
TUBE.
Allow that fillet to cure. When completed, reverse the tube and re-do the same
procedure preventing any epoxy runs and allow curing.
Now, remove the Kevlar bridles from the interior tube. Insert the wing-nut end (minus
