Well, I said I would find a way to make an inexpensive dual deploy device for single payload rockets. It is made from what else but PVC. It is comprised of 3/4" PVC end-caps, 1.5" of 3/4" PVC pipe, three 250lbs swivels, steel leader material(bicycle brake cable works well and pop-rivets with aluminum washers. The shortest practical length of steel cable is used and a loop is formed in the middle of the cable for attaching one of the swivels. A steel crimp is used to enclose the loop holding the swivel. Loops are also made in each end of the steel leader for attaching to the PVC end-caps. A 1.5" length of 3/4" PVC pipe is glued into one cap. 3/16" holes are drilled into each cap and two of the swivels are attached to each cap using 3/16" X 1/2" pop-rivets with a 3/16" aluminum washer (used inside each cap). A small hole is drilled into the end of the cap, (w/o the pipe attached) for passing shooters wire for the release charge. The parachute and shroud lines are bundled into a Nomex blanket or an ironing board fabric blanket and the steel leader is wrapped around the bundle and both caps are pressed together, enclosing the release charge while holding the bundle snugly. The top swivel located in the middle of the steel leader wire is attached to the quick link that is attached to the ends of the parachute shroud lines. The deployment charge leads are connected to the main deployment firing circuit. |
