Hi:
Thanks. I read the free part on Amazon and have ordered one of the books from
the bibliography:
Idea Makers: Personal Perspectives on the Lives & Ideas of Some Notable People
<https://www.amazon.com/gp/product/1579550037/ref=od_aui_detailpages00?ie=UTF8&psc=1>

It's interesting the the tolerance for the early Watts steam engines was 0.1" in the late 1700s. When I was working
with microwave mechanical parts 200 years later (1970s) the no extra charge tolerance was 0.005".
The parts I now (40 years later) buy from the local fully automated machine shop have a no extra charge tolerance of
0.0005". They call it 500 millionths since the coordinate measuring machine uses those units.

Have Fun,

WSJ had review of The Perfectionists by Simon Winchester May 5-6( Books). Sounds
right up this group's alley. As the reviewer states, it: corrals a large cast of
eccentric individuals." Many of which it might have been fun to spend time
with. I've read a few of his other 29 books and most are an interesting ride. I
have one on order. N0UU
