Luggage Lock Project
The goal of this project is outlined at 3DComboLock. My work is liteed below.


 * First, I tried searching the web and Google images for terms like "luggage lock" and "lock disassembled."
 * The web and image search was unsuccessful, so I tried searching patents.
 * the luggage lock patent search returned images of patents, so I then searched Google images for "luggage lock patent," which returned this patent for something mechanically very similar. The major ideas that I got from this were:
 * the detents in the tumblers(21 in image at link) accept protrusions(400) on the slicing bracket
 * when the detents(21) are all lined up with the protrusions(400), the bracket can slide out out the way, allowing the shackle to open


 * after getting the basic concept from the patent, I tried working with the actual lock. It turned out that the bracket was too big to fit where I thought it went, so i tried a few different arrangements, until I found the one shown below:

Next Steps

 * read patent and related patents thoroughly
 * build larger version
 * could use colored pieces of translucent plastic for different parts, shoing operation clearly
 * could use laser cutter to assist in making parts
