When I buy five or six hickory rods, like from TOTW, or whomever, I soak them for a couple of months in #1 fuel oil, or kerosene,, in a piece of 2" plastic pvc pipe, with an end cap glued on.. fill with kerosene, stand them in the corner of the garage, and it makes the wood fairly supple, not prone to breaking.. I have the original rod I made for my 50 flinter (42") still in the rifle, since 1986. best wishes..Les
