This vault has the most advanced lock from the first half of the 19th century: The 1824 Chubb Detector Lock. Watch the entire video before you begin, and follow the assembly order as shown in the video (and like, comment and subscribe to my Youtube channel, if you're so inclined)
Required Parts:
(1) 25mm x 5mm metal dowel (Refer to Dowel Layout image under assembly guide)
(2) 30mm x 5mm metal dowel (Refer to Dowel Layout image under assembly guide)
(2) 35mm x 5mm metal dowels (Used for hinges)
(4) M4xH6xD6 Threaded Inserts
(4) M4 H16 Screws
(1) Skateboard Bearing (608-2RS)
Optional Parts:
Acrylic Panel - Download the file “Acrylic.step”. Order from PCBWay by going to CNC order page, Select Acrylic and upload “Acrylic.step”
There are 24 different keys corresponding to the 24 possible combinations of the 4 levers. Refer to the Keying Guide PDF to determine which lever order and key you want to use.
There are 3 Different Front Covers to Choose From:
Open - The lock is fully exposed and can be manipulated by hand. This is good for showcasing the lock and demonstrating the detector, but it is the least secure.
Acrylic - This requires a custom cut acrylic panel. The acrylic is sandwiched between 2 frame pieces. This is medium security.
Enclosed - The cover has a design featuring the Chubb name and date. The lock mechanism is hidden. This is the most secure.
Tips for Printing:
I recommend printing the Spring and Regulating Slide in PETG, because they have flexing pieces and PLA will deform over time
Ensure your printer is properly calibrated and capable of printing intricate, interlocking parts
I recommend printing Hinge pieces and Jamb with extra walls and higher infill for added strength. I think I used 6 walls and 50% infill
love it, now its printed and assemble I get why the PETG and 6 walls. I used Polymaker shiny gold PETG and its perfect for this project. I plan to make a second one with the printed face
wow coincidences do happen, as I saw part of the video about this a day ago but didn’t follow up, but now came across the model on here just from browsing. sorry if this was it the video but how was this type of lock eventually defeated? or was it simply replaced by other types like pin locks? I wonder how the lockpickinglawer would tackle this lock.
Wow, I'm glad you found it... twice! It was eventually picked by another lockmaker of the time. Chubb added a few security measures and kept selling similar designs, but they were eventually superseded by modern designs. I found an account of how it was picked, which I need to dig up for more info, but I think the guy just applied a ton of pressure on the bolt and slowly lifted each lever until they clicked... but I'm not a lockpicker, so my explanation is probably wrong somehow lol
Another great vault design! Fun to make and works perfectly. I love the idea of models with a historical background. Keep it up! Many thanks @RoccosStuff
An amazing build sir. The parts went together flawlessly. The lock detail you did is truly a work of art. Thanks for allowing us the opportunity to build this safe.
You need to download the stl and print yourself. It would just be way too many plates and get super confusing. It's a very good question, I will update the instructions to clarify later today. Thanks for the question.
