I would just replace it with a new shaft. Most .370 iron shafts will fit a putter, depending on how the hosel is configured.

Does producing mine timbers differ from producing other sawmill products? Sawmill operators, unless they sell mine timbers, know little about the market. Even some mills who sell mine timbers know little about the mining industry itself. That is because other mills generally only supply one or two mines in their life time.
