Technician Tom D. from the
John C. Nordt
company sent me an e-mail saying that he used some
of the formulas
he found here on RF Cafe to help him design inductors for a custom induction
heating vacuum furnace used for melting precious metals used in their
manufacturing processes. He needed to either replace existing equipment
with very expensive commercial equipment or build one of his own design.
It was a first-pass success. Of course the real credit goes to Tom for
having the skill and inventiveness for tackling such a challenge. The
company was founded in 1872 by a German immigrant after whom it is named.
John C. Nordt still operates today as a family business with a highly
skilled engineering and production crew. The
I have linked is a worthwhile watch if you appreciate metals
forging, casting, milling, and finishing, as well as a bit of American
history. The vault used to store gold, silver, and other highly valuable
metals is impressive. I wonder if the employees have to pass through
a metal detector going in and out of the production area? A mere chip
of lathe scrap could fund a large pizza and 2-liter soda.
