Some folks may be aware that I've been occasionally putting together a YouTube video where I build a rocket using only JB Weld for bonding. I did an I500 that was mostly successful and a K455 that came in ballistic, but the fins survived!
Most recently, I decided to give it a go with a CTI M1675 using a tube and G10 sheet I had kicking around. No tip to tip. No fillet reinforcement. Just good composite bonding prep and careful construction. RASAero says 23,000 feet and Mach 2.2. The youtube video will be out on my channel on May 5th, but I wanted to share some build photos!
I started by cutting the fin slots off a longer 3" G10 tube I had and it left me with 33.5". Incidentally, that's just about perfect for a 75/6400 case. I set it up so the coupler/electronics bay gets glued into the airframe and the motor case bolts to the bottom bulkplate. All recovery in the nose!
I also just threw a picture in of this piece of all thread that I rounded off because it came out very aesthetically pleasing.
