I finally got my ferrules from Jann's to put on a blank piece of rod to make my "banty" with. Only problem is that one female ferrule is too big and the other is too small. Are all ferrules the same size for the designated size? Or would another brand of ferrule have a tighter fit? Should I just attach the blank piece of rod with the reel seat to the larger ferrule and then enlarge the male ferrule on the mid piece to fit with epoxy or something?
