I am very familiar with John Kaufman. Several years ago I had several phone conversations and numerous e-mail exchanges with John in an effort to get him to build a low cost resonant frequeny analyzer for fishing rod blanks much like the ones that he builds for analyzing golf club shafts. Unfortunately he had more work then he wanted building equipment to analyze carbon fiber golf club shafts and was not interested.
I came to know John to be an exceedingly competent engineer who has done a good deal of research into the characteristics of carbon fiber shafts that pertains not only to golf club shafts but also to fishing rod blanks. I learned a good deal from the technical notes that he put on his web site (csfa.com) and I think that any custom rod builder that wants to lean more about the characteristics of carbon fiber rod blanks would do him or herself a big favor by carefully going over these technical notes. In my judgment there is no other source that is as informative as John's technical notes.
