Hey all, I designed and built a couple of these sawhorses recently:

(Full photo gallery is here)
You can cut them on just about any 3/4" plywood. I've been using Arauco pine plywood from Home Depot. It's $30 for a full sheet and for this project you only need 36x48" to cut one horse out.
If anyone is interested in making one of these I'd love to get some feedback. Every file you need to make one is here:

This has 3D SketchUp models, a PDF build guide and parts list, and there are also VCarve and Aspire cut files that you can load right up.
This is sort of a sneak preview for you folks, once I build a few more this will go out to a larger group of people.
