I know what you mean. I usually go through one or two a year myself. It would be hard to get too many rods, as you say. But when you build them, they take time to dry, time to rasp out the and fit the handles and the seats. I would guess if you worked on a rod every day for about two hours, you would complete one in about two weeks. At that pace, you probably would not get too many of them hanging around. But when they are done and you get to try one out, you know it's the best you could do and it sure feels good.
