I'll second that Alan, it is really quite refreshing to read about very different work of obviously top quality coming from an enthusiast with particular skills that lie right outside those we see more frequently, all described lucidly with nicely presented photographs.
I took the trouble to look him up and found he makes his flutes as a business for supply to top flight musicians around the world. This is quite apart from being a very good musician himself to be able to make them in the first place.
What really surprised me is the demanding exactitude of the work, in particular the number of cycles some of the keys will make in a year of concert performances around the world—it ran into millions. The flute mechanisms are expected to remain quiet and operate without hesitation under these demanding conditions so as not to detract from the performances. I'm looking forward to part three.
