Yeah, right on. It doesn't get much easier than sawing across the grain and chopping the waste out. You don't even need math, just lay them where you want then and trace the lines on 'em. I am being a bit facetious.

I have worked with both metal and wood in different forms. Wood by far is more friendly than metal, much less technology is needed. Either way it doesn't just happen. Let's see someone just go out back of the house and bring back a flat bar of 1/2" x 6" x 10', just the material alone is tied up in hidden labor, now try to cut and bore holes in it. Maybe we should all just pay some machine to do thing for us, then we could use our creative juices elsewhere, wherever that may be?
