True what the others said. I've "rolled my own" for almost 30 years now. Once you have your jig set you can repair one vane/feather at a time. If you're like me then you experiment with different vanes, different angles, You can pick the colors you want. You don't have to wait. And it's FUN. It like taking a little pride in what you do with your own two hands.
To expand on what Jeff said about cutting from both ends of a shaft, he's speaking of carbon. Carbon shafts can be "not straight". If this is so it is usually at the ends. So what many of us do is cut an equal amount from each end when we cut the shafts. This almost ensures that you are getting most imperfections out. It's not fullproof but works pretty well.
