General machine experience

I have worked with screw threads since 1972 in Los Angles first as a drill press operator. Looking for better opportunity I then went to for Pennoyer-Dodge Gage Company in the manufacturing of precision thread gages 1972-75, and 1979 till 1987. My duties included set up and operation various types of grinding machines to include O.D., various Excello thread grinders, Blanchard, and surface grinders.

1987 to 1992 I thread ground precision lead screws for five years at Cal-Micro in San Jose CA.
