[CAUT] Mitutoyo gauge

[Edward Sambell]

Thanks Ron, I did not know this; Incidentally, I had a Starett thickness gauge 
for twenty-five years , before it wore out, and then acquired the Mitutoyo. They 
are almost identical. I only use it as intended.

Hi Ted,
It depends. You don't need a super precision lab quality machine to grade felt. 
A tire durometer, from a racing supply house, is a Shore A scale and cost about 
$60 USD. Since we don't order anything by durometer numbers, we're just taking 
comparative readings and that's a good enough tool for our purposes.
