Anyway, here are a couple of repair tips. Two old and one new.
- To replace a broken shock cord, you can install a Kevlar leader along the side of a launch lug as follows:
- Punch two small holes, one on either end of the lug in the fillet area.
- Feed the Kevlar twine into the back hole and fish the end out.
- Tie a double knot and pull the knot against the hole.
- Feed the loose end through the upper hole and fish it back out.
- Keeping the line taut, apply a fillet with 5-minute epoxy, and work a bit into the rear hole where the knot is.
- If not exclusively using the Kevlar as a shock tether, you can attach some of your favorite sproingy material.
- Add a couple of folds of tape (I prefer duct tape) at the point where the Kevlar line touches the body tube. This will reduce Kevlar-induced zippers.
- Now for the new one. I found several of my Nomex 'chute protectors were tearing in the middle. Holes will allow gas to pass so this is not good. I found duct tape works as a decent patch material. It adhered well and was still in place after the flight. I don't know low long it will last, but it's cheap and easy to replace if it falls off.
