I had a similar experiance with a 4wt rod of mine, not matching parts. I was however able to repair it using the following instructions as a guide........

I used pieces salvaged from other broken rods and fitted the broken area with a sort of splint, and wrapped with thread. The repair shows, but the Rod casts as well as ever. I'm glad to have a favorite rod back!
