This article shows a bit more of the "background" of what can be done with some of the modern CNC routers and wood cutting equipment. This particular design really doesn’t seem that good to me (and looks to have an awful lot of waste), but the idea of machine cutting parts is growing, and I think will become more and more popular in the home build world. Already some people offer kits with machine cut parts. As more designs become available as electronic files from the designer, then having major parts cut locally for home assembly becomes more practical. Designers are moving to the electronic world… we just have to work out ways to get the cut files from them at reasonable costs (while protecting their valuable work and keeping it profitable for them).
