"Super Shroud" Article in the Apogee Peak Of Flight

The Apogee Peak of Flight Newsletter #349 features an article I wrote about how to make "Super Shrouds".
You can read it HERE

It's a simple solution for a typically weak link in model rockets.
Nesting a second shroud inside the primary visible shroud doubles the wall thickness.
Using this method, transitional shrouds (joining an upper payload section) are smoother and stronger. Nozzle shrouds are less prone to damage on a hard recovery.

On a related note:
Manuel Mejia gave me a copy of the Journal of FAI Space Modeling and the British Space Modeling Association. They mentioned the article on Replaceable Kevlar Shock Cords from the POF issue 338.
