TEMPTING TO COMPLETE IT.
8. Once the GLR Hard-point Recovery Sys-
tem Anchor is prepared, you must insert the
GLR Hard-point Recovery System Anchor into
the airframe as follows: You are provided a
glue stick dowel. Do not snap it or otherwise
alter the length because it will serve as a meas-
uring guide. Mix some J.B. Weld (do not use
epoxy). Measure the dowel and make a mark
on the dowel at 15” and 16”. Measure and
mark the airframe also at 15” and 16” from the
forward opening of the airframe. (Because Gi-
ant Leap Rocketry uses the finest resins when
fabricating our fiberglass airframes, in good
light you will be able to see through the air-
frame as you insert the GLR Hard-point Recov-
ery System Anchor.) With one hand, hold the
airframe horizontally (i.e., flat, not upright).
With the other hand, dip the glue stick into the
mixed J.B. Weld and insert the glue stick UN-
TIL THE 16” LINE ON THE END YOU ARE
HOLDING IS FLUSH WITH THE FORWARD
END OF THE AIRFRAME (the end opposite
to the fin can). Use care not to touch the inside
of the airframe with the J.B. Weld. Apply the
J.B. Weld in a ring to the interior of the air-
frame. The ring of epoxy should coat the inter-
nal circumference of the airframe from the 16”
to the 15” mark from the forward end of the air
frame.
It is important to avoid getting the J.B. Weld on
other areas inside the airframe, so do the best
you can. You will be able to clean up some
later. Repeat the procedure as necessary until
you have a full-solid ring of J.B. Weld inside
the airframe. Remove glue stick and clean the
J.B. Weld from your glue stick.
Before the J.B. Weld cures within the airframe,
insert the GLR Hard-point Recovery System
Anchor through the FORWARD end of the air-
frame. Hold the GLR Kevlar® Shock Cord and
insert the GLR Hard-point Recovery System
Anchor NUT SIDE IN FIRST, making sure that
the free end of the GLR Kevlar® Shock Cord
points FORWARD, or away from the GLR Fin-
Can. Using the CLEAN glue stick, push the
GLR Hard-point Recovery System Anchor all
the way down until the mark you made on
the glue stick is even with the FORWARD
end of the airframe. Once in place, immedi-
ately take a moistened paper towel with alcohol
or thinner on the end of the glue stick and swab
out the inside of the airframe removing J.B.
Weld where it should not be. This is important
because you do not want your recovery system
hanging up on clumps of J.B. Weld. AVO I D
