Tim, you’re at the top of the game buddy that zipper shield is awesome. What an awesome idea. Nothing could be more heartbreaking than spend a lot of hours getting it just right the finish on your rocket that he is getting tore up by a zipper. Great idea thanks buddy.
I learned how to make a daisy chain in my youth, although I learned it is called a gaffer's knot. The nice thing about them is they do not tangle with other cords. Also, if working with a cord with "memory," it will zigzag instead of coiling up in loops. Try using one for your launch controller cable!
Nice techniques. I suspect these would also help prevent Kevlar shock chords from breaking the hard points they are connected to (like plastic nose cone loops).
I've had rubber and elastic shock cords break but I've never had a kevlar cord break. I use pretty long kevlar shock cords- 8' to 10' for rockets I launch on D motors. I have had snap swivels break though so I had to start buying much stronger ones. However with kevlar you use longer cords and longer cords are harder to pack inside the rocket in such a way that they can stretch out later without becoming tangled. I've used the daisy loop method, I haven't tried masking tape.
I have used both these methods on mid and high power rockets. IMPORTANT NOTE must have cord entering and exiting the same end for the tape method. May not matter for kevlar but with nylon shock cord the tape won't tear if the cord enters one end of the bundle and exits the other.

Wow above techniques are very useful, I used this for my kites bridles and it's always works.
Glad that it works well for you! Thanks.
Look up tubular nylon, and get rid of that stuff.
Everyone always makes fun of my 20 foot shock cord on my katana jr.
Or use wax
