Google SketchUp is a wonderful program for woodworkers interested in 3D modelling - with a little practice, it is far easier and more suited to designing your next project than are CAD programs. (I've used both AutoCAD and TurboCAD: powerful and unfriendly, and they don't allow you to design in 3D nearly as easily as SketchUp does.) A further advantage: it's free. Its 3D Warehouse contains many user-submitted designs, free to download and use. For example, the 3D Warehouse contains 124 workbench models as of this writing.
Following are SketchUp models I've developed. Feel free to download, modify, use as much as you desire. Enjoy ...
While Google SketchUp is much easier than CAD software, there's still a learning curve. I've found Google SketchUp For Dummies by Aidan Chopra very helpful; you could also view various on-line tutorials, or those that come with the program.

Bow saw, turning saw, or frame saw
The bow saw, turning saw, or frame saw is history's version of a band saw. It cuts smooth curves and tight radii; the blade allows for long strokes that cut faster and more evenly than a coping saw. Plus, it's fun to build and fun to use. More
