  I’m a heavy equipment mechanic that does some machine work on the side, and I enjoy trying to work to tighter tolerances than necessary. Some of the farmers and equipment owners I make some parts for think I’m working to ridiculous tolerances when i talk “plus or minus a thou”, I’m not gonna let them see this video, then they will know I’m just a hack.

  As a machinist for the last 51 years, and finally being able to machine components to +.0000/-.0001 in a production environment, I was beginning to feel pretty good about myself. &nbsp;Now I see this and feel like a hack!!! &nbsp; Thanks Robin.... I&apos;ll be sure to mention your name in therapy!!! &nbsp;LOL

  &quot;think about everything as if it was made of rubber&quot; - I was taught that during a scraping class with Mr.King

  Takes a lot of skill to find such a precise gage ball buried in a cylinder of carbide..

  When Robin has an apprentice, they must first master the art of &quot;Kimwipe on, Kimwipe off, Kimwipe on, Kimwipe off&quot; before they can learn the truly powerful techniques.

  that moment when you can see your face on the ball during the lapping process...

  That&apos;s an excellent explanation of Hertzian contacts! I think your emphasis on the uncertainties in material properties is also spot on - this is often completely glossed over.

  When I was a kid I would watch my grandfather hand lap the glass for the 8&quot; telescope he made. He would assess the quality of his work using home made testing equipment. He was shooting for 25 millionths or less as I recall. &nbsp;He would have loved to have the testing equipment you show in your videos. <br><br>Great job with the video and some of us do enjoy geeking out.
