You advertise a "Woodworker's Dial Caliper."
What's the difference between a woodworker's dial caliper and any other dial caliper?
Dial calipers originated as measuring tools used by machinists and were primarily used in metalworking, where fractions of an inch are
typically expressed in thousandths of an inch. Their round scales were therefore graduated in
hundredths or thousandths of an inch.
Given that wood expands and contracts significantly due to changes in humidity, woodworkers aren't
generally concerned about thousandths of an inch. We think instead in much more civilized fractions
like halves, quarters, eighths, sixteenths and thirty-seconds of an inch (at least here in America
Highland introduced the
woodworkers dial caliper
to the American market a few years ago to address this
inconvenience. The scale on its dial is graduated in 64ths of an inch, and the common fractions that we
use like 1/16", 1/8", 3/16", etc. are clearly labeled.
The dial and its graduations are large enough
for you to easily distinguish dimensions as small as 1/128".
