Adam embarks on his next multistage build project: a 1/12 scale working recreation of a mechanical vault door! Inspired by his recent acquisition of an automatic hacksaw that can cut the solid cast iron cylinder that will become the vault door, Adam pulls from his extensive research into the operation and gearing of these doors to start making his scaled replica. The first step: machining the central ring and spur gears from which the locking pins will activate the vault lock!
