Men & Used Mill Rolls
Note by George, III: I still have the layout tools,
a
Starrett vernier protractor, Brown & Sharpe
"vernier" caliper where one uses "eyeballs" to
align the index marks and a 40 tpi thread and dial
to interpolate, and radius gauges that George, Jr.
used to make the templates the machinist needed to
make the grooves in the rolls.
