I've been frustrated with the aft closure on CTI 54mm motors due to my inability to think of a way around the externally threaded tube with the closure I can't make work without a thrust ring. I had an idea for an extended AFT closure that I thought I'd propose and let others take the idea and run. What if a Stepped closure was created that turned a 6 grain into a 6XL or a 5 into a 6 or 6XL. The idea is that the after closure be made to still possess the thrust ring and thread onto existing casings, however, now there's a step-down zone to motor diameter that can be utilized as an interstage matting device. This would allow for some very efficient flights using CTI's big long burn motors in 54mm with an efficient and lightweight mating system. I'll have a drawing of what I'm proposing in the next couple of days but hopefully, this gets some people thinking about a really cool aft closure that opens CTI 54mm hardware up to some pretty crazy two-stage projects.
