On the Dewey rods, several years back Dewey changed their handles so that they have aluminum races for the bearing balls, instead of the old system where the balls ran directly on the plastic handle material. At the time, I changed my old handle for a new one. We clamped the rod in a vise, between a couple of boards, to protect the coating, and used some vice grips on the aluminum sleeve at the front of the old handle to break loose the threaded connection. The rod threads into that aluminum part a short distance. After cleaning the threads, some epoxy was applied, and the new handle threaded on, and tightened with pliers with padded jaws. I have had that rod since I discovered that the "new" Marksman's Choice (which was renamed Shooter's Choice) was dissolving the celluloid coating of my Parker Hale rod. The nylon coating on the Dewey is still undamaged.
