Estes Long Tom #3016 Build, Part 12, Shock Cord and Parachute Ties
The Kevlar shock cord is purposely short so it can't cut into the top of the body tube at ejection. The only way to tie on the elastic shock cord is to feed the Kevlar out the back end.
The Elastic is tied on using the low stress loop knot: CLICK HERE
The upper body section is tall on this model.
The elastic has to be extra long so the upper body won't swing into the lower section during recovery.
Before tying a loop knot for the parachute snap swivel, hang the body so you can see how long the elastic should be.
Here's the upper end of the elastic.
The parachute snap swivel loop goes a little closer to the screw eye on this rocket.
