Engineering Projects

United States Navy
It was found that the main propeller-shaft internal dynamic seal was failing on all Arleigh Burke Class surface ships.  This was from many years of rough seas having bent the bulkheads out of alignment.

I designed an in-place machining device that could be used to re-machine the bulkhead mounting pad concentric to the shaft within +/- .010 inch.

The project resulted in the portable device being used on deployed Navy assets, resulting in
$60,000 dollars in cost savings per seal.

Diamond Innovations
Company needed way to extract loose product from the bottom of their fleet of “lights out” Wire EDM.  I designed a custom miniature conveyor belt system that automatically extracted the product from the tank to a dry container.  I both designed and physically built this conveyor system.
