A Chesapeake, VA, propulsion manufacturer called CBG, LLC with a small problem with a tap in a propeller. Wärtsilä makes some of the largest propellers in the world, for the largest ships in the world for the largest Navy in the world. The tap was a 4-inch tap broken off. A plan was made to disintegrate the tap starting the next day. CBG set up one of its Cammann Inc. portable Metal Disintegrating Machines and using a squire electrode disintegrated the flutes off the broken tap until the tap could be removed. With no damage to the threads a new tap was used to complete the threading process and the propeller was ready for shipment ahead of schedule.
