Wooden Combination Lock Demonstrates Inner Workings

Lockpickers, school yourself.

The incredibly prolific, woodworking whiz Matthias Wandel demonstrates the inner workings of a combination lock with his wooden mechanical model.

"In terms of neat mechanical things to build out of wood, I figured a single dial sequential combination lock would be a neat thing to make. It would be relatively simple, involve movement, and also show people how a combination lock actually works.

I spent some time thinking about it, and the design I came up with was the simplest that would also be visually appealing that I could come up with. Unlike a real lock, my priority was to show how it actually works."

Once you're familiar with the mechanics of the combo lock, learn how to crack it!
