I've finally completed the BerthaVostok I built for my local NAR club, HUVARS, Bertha-Bash-o-Rama-Thon! (see https://www.rocketryforum.com/showthread.php?s=&threadid=6354 )
The concept was inspired by Sandman's Gemini Bertha (see: https://www.rocketryforum.com/showthread.php?s=&threadid=874&highlight=gemini+AND+bertha )
The rocket used all of the original Bertha parts except I replaced the shock cord with Kevlar and the launch lug with one from a Baby Bertha.
The basic build is as described for Peter Alway's "Simplified Vostok". I upscaled the design to a BT-60 and instead of using Peter's templates, I made my own using the graphics from a paper model downloaded from the web. The graphics on the body tube were resized from the paper model and printed onto full-size label paper which I used as a body wrap (a technique I learned from JFlis's ACME Spitfire's "skins").
This was truly a melting pot of Rocketry Forum lessons, techniques, and ideas. It's been a blast to build.
