I don't normally like to just post videos, but I think everyone here would like to spend time in this shop, which has to be full of the most accurate equipment known. The gentleman seems to be a prototype machinist, and is passing down knowledge at this point.

That gentleman has a passion for his work. Truly a 'skunkworks' type of operation. I bet he has a client list that includes many highly sensitive governmental and industrial organizations.
Great video -- enjoyed it very much. Old Car Guy and Mr. Gelbart could probably sit and talk shop for hours on end.
