I am going to do my first rocket up using Kevlar shock cord. I had thought to keep the Kevlar short, just below the end of the body tube, to avoid zippering, and attach some elastic to that. I would probably be attaching the Kevlar to the engine mount, and notching the outside of the centering rings and running the Kevlar up the side of the tube.
What concerns me about this approach is this: What if the elastic suffers damage and needs to be replaced; the end of the Kevlar shock cord won't be protruding out the end of the tube so it'll be hard to access to attach a replacement elastic cord.
Any other suggestions for a Kevlar noob as well?
