The Home Machinist!

I have an inspection sheet for a Clausing 5900, with detail of each test (printed) and the results (hand written in pen).

It has the serial number written right on the inspection sheet. I think the inspection report is actually part of the owners manual.

On the other hand, the inspection sheet for my chicom surface plate says 0001 with no decimal, so I can't tell if it's 0.001 or .0001 (heck, I'm not sure it's not 0.001 feet).

The automotive industry inspects each and every car/truck that leaves the plant. Inspectors will pass known flaws as long as the flaw doesn't present a safety issue. The thinking is, pulling a car from the assembly line for repair, would disrupt the assembly line progress. Knowns flaws are expected to be picked up by issuing service bulletins to the dealers. I would expect the same procedure is followed by tool manufacturers under guarantees and warranties.
