Wow! This really is a neat gadget. I have more than my share of thumbs (can't even cut two boards the same length) so suspect that I couldn't manage the project. But, it is ingenious and I am envious of both the design capability and the skill to carry it out.
Build a better mousetrap and the world beats a path to your door.
Thanks for sharing this. I'll print out those photos and do some thinking.
