I judged the book by its cover. Bad idea. There is ONE wooden works clock in here. All the rest are just frames to stick a battery operated clock into. That doesn't mean it's a bad book, just not quite what I was looking for.
The clocks are interesting, although I doubt anyone would want to make more than 1/4 of them since they're all over the board in styles. The wooden works clock is one of the simplest, but still beyond my skill level & patience on the scrollsaw. There are a lot of good patterns that can be used for other things besides clocks, too. There are puzzles & fretwork that can be adapted for toys, picture frames or what not.
While the paper book is nice, it's a PITA to get a decent copy out of unless the spine is taken apart. I kept getting warped & black edges, so I did some searching & found a PDF copy. It's not done by the publisher & isn't complete, but it does have all the patterns I wanted so I could copy them into a program (Irfanview, a super, simple, free graphics program) & print them out in various sizes.
I've had this book around for years & have read through it several times. I'm currently doing a couple of projects using parts of it, so I thought I should add it to my library here on GR.
