I haven't started to assemble the rod yet Lee, so the reel seat hasn't been glued. But yes, the shoulder does fit the seat nicely. So, in your opinion, the rest of the fighting butt should fit into the blank? I will give that a try, however, I the part that doesn't fit is made of metal. Any suggestions on what I should use to turn that down? Will a coarse grit sandpaper work?

Thanks for the advice Lee.
