I use the Kevlar leader method and tie tubular elastic to that. Always at least double the length of the cords Estes uses in their kits. I think Estes uses JOKE-length cords as a conspiracy to sell more kits due to the inevitable damage upon ejection. Also lean toward same theory regarding "shotgun" ejection charges. The ejection charges in motors from the 70's to 90's were far more consistent and milder but plenty effective.

Speaking of which THANK YOU for the innovations of the removeable kevlar shock cord mount and the "extended" Stine shock cord mount. I was skimming through a summary of Chris Michealsson's blog posts about shock cord anchors that lakeroadster (TRF) had compiled at Rocket Reviews, and your name had come up in conjunction with these. Saw this just a couple of days ago, and was surprised to find out you are somewhat of an inventor besides a knowledgable scale model enthusiast!. We all owe you a debt of gratitude. Bravo! |

To overcome this, I designed a "paperclip variant" of G. Harry Stine's "Shock Lock" (see: http://www.oldrocketforum.com/showt...22Shock+Lock%22 ), which allows the shock cord to be replaced when necessary; a tri-fold shock cord anchor could also incorporate this modification. (Speaking of Kevlar, "mojo1986's" Kevlar-zippered body tube repair method [see: http://www.oldrocketforum.com/showt...ock+cord+anchor ] is also well worth preserving for posterity! Especially if the model is a lovingly-constructed scale model rocket, getting a "Kevlar zipper"--at any time, but especially during a contest--would be frustrating and/or upsetting, but his repair method restores such rockets' appearance and local structural durability.)
