It must have had a manufacturing defect. The carbon split just above the first ferrule while casting. Its a 6 piece 7.5 foot 4wt graphite rod. I sanded down a solid fiberglass rod to fit the inside diameter of the broken section. I loaded up the broken section with JB Weld and inserted the fiberglass blank. On the outside I applied a layer of JB Welds and wrapped a layer of thread into it. after it set up I pit a reel and line on it and did some casting, works like new, Tomorrow when its fully cured I will add another layer of JB Weld to clean up the appearance
