Anyone know where I can purchase a lead standard or standards. I would like to build a hardness tester but It would be nice to have some blanks with a known hardness to use as a reference.
Thanks
Jay

See the Rotometals ad at the top of the page.

Bill Ferguson, down Arizona way, has pure lead. Google him.
