Take my money, I need a copy! See you at the next launch. Gheem “We need more boom.”

I plan on offering brand-new paperback copies of G. Harry Stine's, Handbook of Model Rocketry, 7th edition, for sale at all upcoming launches. Price is at my cost - $13.87. I am not making any

The 300-lb braided kevlar line that I installed in my Estes Fat Boy (the original BT-80 version) has held up well since 2002 or so. It's pretty thin stuff so it's not like I'm coiling up a rope

No rush. Don't know when I'll be making it back up again any ways.

Yeah, I gotta get back up to an Aurora launch. My first time was 2 years ago 2 launch dates in a row and haven't had a chance again since. Any word on that prospective launch site in Alliance?

I can do what Mike suggests next launch I am at. Dunno if that will be this sat or not... John

I dont have that capability. Computer retard here. I can take pics of swivels, thats about it ... and a snubber, once i find one... John

An in person “how I do it” session would be best! Mike Nowak

Any chance of adding diagrams/pictures?

Great ideas ! Bob, you beat me to the punch in shock, and also degradation. Having thought about it since my original post, while I have yet to have a failure of the 100# with small rockets, some of

That could be what it’s called. I didn’t think of it myself. I read about it and tried it.

Sounds like a modification of the "lariat loop" which works well. -- Mike Nowak

I have a good idea of what your talking about, thanks again!

I’ve tried a method of making the Kevlar shock cord replaceable on model rockets. The method works well but is a little difficult to explain in an email. Basically, You poke a through-hole in each

Great info, thanks!

Thanks!

One thing that must be considered with Kevlar is degradation. 100 pound line may work the first three flights but if the shock cord is close to the ejection charge then each time it is being exposed

Yes, but Kevlar is excessively strong for its diameter. 100 pound test Kevlar is like carpet thread.

Okay but what about the actual size of the kevlar cord? Wouldn't heavier pound ratings have more braids and be thicker?

Think about it this way... if it's rated to #100, you could attach a 99 pound weight to the body tube and pick the rocket up by the nosecone with the weight attached. The rocket itself would fail long
