The models themselves are nicely proportioned and well designed. Any of these models would be a welcome addition to the desktop of a mechanically inclined person.
I have read this book from cover to cover and browsed the drawings for inspiration. Beautiful color photos in the center of the book demonstrate the skill the authors have great in fabricating with wood. I have found this book to be very useful in this regard. Note: some of the projects in this book are best accomplished with a lathe.
Should you choose to buy this book and make the some of the models, you will find that it contains good project lists and plan drawings from which to work.
Amazon has a nice "Search Inside" this book feature for this book to let you preview the book's contents.
