My dad worked for L.A. County for 35 years, and his favorite padlocks were Yale and American 5200's -as you can see from the date code, these locks are at least a quarter century old
After three 10 minute spp sessions I finally was successful in opening one of the 5200's, and immediately thought about converting the core into a practice lock. I filed down the top of the bible, and during the gutting process I noticed that all of the pin stacks acted as if they were glued together.
Since I have a dozen of these old locks at my disposal, and if would be nice to convert all the cores to practice locks that can be readily re-pinned, what is the best way to remove the oxidation/corrosion from the pins? I fabricated a mini pin lathe using a 12 volt drill motor and a small collet, I'd like to recut the serrations and create new security pins to practice with. Is there a practice for reconditioning old locks with oxidized pins?
I also have eight Yale padlocks. It took me ten, 10 minute attempts to maneuver around the warding, get the pin spacing right and pick one of ém -so I'm now kinda smitten with these locks. Since the Yale locks are older than the Americans, and cannot be re-pinned or cleaned internally, is there a procedure for cleaning/reconditioning these locks?
