Today is the 148th anniv. of the birth of Charles P. Steinmetz.
It's also the 98th anniv. of the birth of John Presper "Pres" Eckert Jr.
If you're not familiar with it, there is a good story about Steinmetz fixing a generator for Ford here:
Speaking on the subject of Henry Ford, happened to be at one of his larger failures just the other day (this image is NOT mine!):
"Ford's Folly", a monument to poor planning 
The grist mill is great however, and still in operation. Even better is Nathan, the caretaker. Not only does he mill flour and stuff with the mill daily and sell baking mixes and the like, he MAINTAINS the mill by hand. Every part replaced is a hand-made part, most carved from wood. He's a fascinating guy to talk to- if you let him, he'll drag around to weird little spots and tell you how long it took to replace a hand-carved wooden gear three feet across. And show you how he made it. Truly defines the word Artisan.
focalist:
Invoice:Making chalk mark on generator $1.
Knowing where to make mark $9,999.
Sounds like the old joke:
Replacing resistor: $1
Knowing which resistor to replace: $100
