  • 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.Huge thank you to all of my Patreon and PayPal supporters and specially to:Arthur BeaulieuprahS ProdsAfreeflyingsoulMicky McKayAdel AlSaffarAlan HansonAmanda Taylor, EsqAndreswara HermawanAndrew PhillipsDan WilliamsGregoryJoan CasanovasJoel MillerJohn RomeroJonas RichartzJonathan HeckermanLVEMarc PPaul AmbryPaul MampillyTallBaldandCraftyTrevor KamVince ValentiZachary GrimesTimestamps:00:00 intro00:10 cutting the bolt in pieces on the lathe00:53 making the side plates of the lock02:14 making the first pin, shaft for wheels (fix side)03:46 making the second pin, upper shaft (fix side)04:37 making the third pin, key (movable side)06:33 making the fourth pin, upper shaft (movable side)07:16 TIG welding the pins and side plates together07:35 sanding and polishing the welded parts07:57 filing the slot for the secure ring08:16 making the wheels with numbers out of brass09:16 etching the numbers with ferric chloride10:52 knurling the whells with the numbers11:48 making five tiny springs with 0.3mm spring steel wire12:20 showing the five steel balls12:24 assembling the wheels with the numbers12:44 making a secure ring with 0.8mm spring steel wire13:13 assembling the secure ring13:21 showing the finished combination lockTime and costs of this restoration:I was working on this project over 2 weeks$5 stainless steel bolt M20x70$40 knurling wheel$2 printing the numbers$15 steel balls and spring steel wireMy camera:Panasonic HC-V180If you have any questions about the process, machines i'm using or other stuff, just ask me in the comments.

    That awkward moment when you realize thieves are more interested in stealing your padlock than whatever is locked behind it.

    Awesome project man!
    There's a lot of skills here.
    At first I was not getting the purpose of that jig used around 2:30 to hold the piece, if then it has been made all of the same size.... Then I understood that you where trying to make the whole thing out of a single screw :) amazing again!

    Amazing job! But I'm afraid that this lock can't hold a real pressure.

    Plot twist: Me made the bolt himself as well, out of an old frying pan handle. That he made from a bicycle rack.
