In each bi-monthly episode of DiResta (every other Wednesday at 2pm PST), artist and master builder Jimmy DiResta (Dirty MoneyHammeredAgainst the GrainTrash for Cash) lets us into his workshop, to look over his shoulder while he builds whatever strikes his fancy. On this episode of DiResta, Jimmy reverse engineers a key to open a vintage lock. -Stett Holbrook

Jimmy’s Notes: I collect many things that inspire my thinking and inventing. Vintage locks and keys are always very clever in their design. In this video I make the key for a large door lock I picked up at a flea market in upstate New York. Inside the lock you can see a brass plate that is the main mechanism. It was handmade by someone many years ago. I wish there was a YouTube movie of the person making this mechanism: adjusting the spring tension and bending the plate just enough to get the parts sliding perfectly… this internal plate seems to have been made 50-100 years ago and it still works! I like reverse engineering the keys for these locks it is a great mental exercise.
