While we wait for the pictures, here's my understanding of his
process: Nickels are about .73" thick and .835" wide. He cut

..73 is a typo for .073. Incidentally, .073" is based on
measuring a stack of 4 nickels; individually, they measured
at about (a) .069 to .0715, (b) .074 to .077, (c) .073 to .079,
(d) .072 to .078. Thickness depends on what chord you measure,
and I show the min and max out of about 5 measurements per nickel.
