Well, there is no mention of precision or time measurement. Seems like a
simple, harmless presentation to me. I will admit that from "time to time"
my wife does object to some of his work! We do watch "Frontline" and are

Dave,
I, too, hate piles of dumb little boxes. So when the Z3801 appeared I went
on line, bought some sheet aluminum of appropriate thickness, cut a "panel

the start of a hacksaw and then finished the clearance hole
Interesting topic! Of course I no longer wear a watch since such a habit
after advancing well into retirement seems pointless but I did want to point

You might want to consider the possibility that there is a whole world of
manufacturing that does not deal with millions of a single item. And
prototypes are not part of the process. When a product life might extend
