[dorkbotsea-blabber] meter scale (was glue question)

[Doug Bell]

That was my first thought as well, because those
things are usually measured in yards, but why would
you need a zero center meter for that?

It seems to me the rate of travel of fabric, thread,
string, wire, wood, metal, etc. through a production
process would be in only one direction, or if in two
directions, for example a loom shuttle, there would be
a separate meter to measure the peak speed of each
direction, or at least the meter would show the
absolute value of the speed. Meters aren't useful if
they're always rapidly changing, only if they sit
still for a while.

Automobile speedometers indicate only for forward
travel; fork lift speedometers probably indicate for
both forward and reverse, but wouldn't need to show
the direction of travel, so they would display the
absolute value of the speed. Air vehicles are the only
things I can think of where an indication of the
direction of travel would be of use to the operator.
Also submarines, but not up to 100 miles / hour.

That's plausible. My first thought was a yarn or
yardage counter for a textile mill, or a paper mill.
Those speeds are possible, from what I understand.
