Hello All, Someone was kind enough to point out the book 'Letter Slate Cut". I got a copy of it. Nice book!
Easy to read, though I did need to read some passages a few times until I was familiar with the jargon. There isn't that much jargon, you just need to wrap your head around their word usage. There are a couple of pictures of sundials in it, and they look quite nice. My next sundial is going to be made of slate! And I can't wait to start... Chuck
