I turn a Stainless Bolt into a Combination Lock

In this video i'm turning a stainless steel bolt into a nice little combination lock.

I was always fascinated by those antique combination locks. I really like the design of them. A few weeks ago I bought one from eBay, but it turned out to be a cheap fake copy. I was really disapointed. Well if I can't buy one, then I make one myself. It was quite a challenge to get all the parts done and fit together, but the end result speaks for itself. I'm very happy how it turned out and I'm glad I made it.

I hope you like my work and the video.
