When the Piston Assembly is completely cured, slide one buckle over the shock cord approximately 6 feet from the end
of the body tube. Then slide the Piston Assembly over the shock cord (Piston Cap facing forward as shown) and slide the
other buckle over the shock cord within one inch of the Piston Assembly. Securely tie the loose end of the shock cord to
the molded loop on the nose cone with a square knot. Do not apply cement to the knot on the shock cord.
4.
Fasten the fabric parachute to the shock cord at a point about one (1) foot away from the nose cone in the following
manner: Stretch out the shroud lines of the parachute so that the lines form three (3) loops one on top of the other. Lay
the shock cord across all the shroud lines. Pass the canopy of the parachute over the shock cord and through the three
(3) loops made by the shroud lines and pull tight. Pack the parachute and insert the nose cone into the body tube.
