[ARC5] Source for #2-64 cheesehead screws?

[Robert Rode]

You guys sure are talking about small stuff, I hope you can even see it let
alone cut them on a lathe..When I was an apprentice, I made a couple of
"button heads" for my dial indicator they had 48 threads, I cut them on an
old military paid for Monarch Lathe at International Harvester Co. ..think
It was a 18 x 72 inch machine,..Always a "glutton" for punishment,..That
was in 1971, I cud see back then !!   18 inch diameter chuck.....we used to
always see who cud do stuff !! WE decided to see how many guys cud machine
off figures on both sides of a penny,..First die I made wud trim the O.D.
off a penny and use it as a dime in coffee machine..
