I have been doing it for a while and it works fine. Actually, it works great.
You just have to do a little measuring and marking to know where the actual nocking points will be. You can build up one nock "area" with something like teflon tape (a Rick ****** idea), or you can just switch to a different serving material to get a thicker or thinner serving.
With a good serving tool, you can do a lot of experimenting, and LEARNING. I have not bought a string in 24 years, and don't intend to.
