This is getting serious. When you see the Airbus hinge, you can see that machining that would be very hard. Saving weight in an airplane is EVERYTHING.

Thanks Greg.

CNC for carpenters

As some of you know, my father had a couple of careers. Depending on the current economic cycle, he was either a carpenter or a gifted fabricator of aircraft skins. The transition came several times in my life, usually on a Friday afternoon when he would get laid off. During his carpenter life he was a framer and swung a 16 oz. hammer for a living. I wish he could have lived to see this. How small can CNC get::
