I have enjoyed my time corresponding with Carey Parks. We talk colors, engraving, music, and the lot.
Butyrate and Provista (PETG) have specific acoustic properties and it is something that I would like to study further. For example, Onda Corp. has some data on acoustic attenuation of various resins.
Also, as this blog expands I’ll have a bunch of pictures of artistic penny whistle designs and hopefully, many of Carey’s.
In the meantime, this is a start.
