Bob,
Thank you for the kind words and suggestion. Surprisingly I could find very little documentation on Gene's projects. What he did have were almost exclusively from the projects he did at Olde Mill, and in most cases these included some mylar templates he made plus pictures of the original. I spent an entire day in his shop going through his project binders and drawers looking for good stuff to include in the book, and what you see is pretty much what I could find. I think what Professor Hummel wrote for the introduction in Inspiration was very observant. Gene knew almost all details just by looking at a piece, and other that a few pictures with a six foot folding ruler he didn't need much else. (He did take lots of pictures of carvings and did rubbings if possible.) No doubt the information that was shared through his Olde Mill classes is by far the most detailed you'll find.
But if you are interested in another book... Keep checking this site, because I will be announcing a companion book in a few days about Gene's tool collection. This will be available as a pdf download. I may make a hardcover version available as well for true die-hard Gene fans.
Best Regards,
Tom
