When I set out t' build me own launch pad, ya bilge rat, I was lookin' for a design that was light weight, easy t' use and store, and had a low center o' gravity. Avast! My search led me t' a design that fit me needs perfectly; a design based on John Coker's ProRail Base (see link below). Avast, me proud beauty! My build had a couple deviations from John Coker's design: I used 2" square tubin' instead o' 3" tubing, and is fully bolted, ya bilge rat, no weldin' required. Ya scallywag! Since t' filmin' this video, ya bilge rat, I have replaced all o' t' hardware with stainless steel hardware, and I have added a blast deflector. http://jcrocket.com/prorailbase.shtml www.dragonworksrocketry.com
