The backstory is that I'm part of a student club. We found some parts laying around from a Carmack Prize attempt 6 years ago. We decided to resurrect the project. Turns out the 6XL motor case we salvaged lithobreaked from 23,000 ft. It's almost imperceptible, but there was a small buckle in the top of the case. We ended up cutting the case to 6 grain length. We thought we could do single point threading in one of our machine shops, but none of them actually had a lathe with a bed long enough. I was hoping someone would have one for sale (for not $600). I guess we'll end up outsourcing the machining.
I have a CTI Pro98 6XL complete motor, XL spacer, tailcone, and wrench. It has been used but is in perfect shape. The tailcone was painted red and the paint bubbled from heat. Retail value new is $710 plus the tailcone which I believe is out of production. Make me an offer.
