  1. Bill, nice video. However, where do get the replacement parts to rebuild a lock that you've had to drill out and that maybe had a broken shackle? Can you simply buy the parts new or do you have to cannibalize other old locks for the parts?

  2. Hey, Bill…..it's Will. Ha, thanks for the ideas. I've always liked locks and I just got this new job as a meter reader and in places we have company locks, i find old locks people toss in the corner. I don't really know how to pick locks, I bought a reallllly cheap little set for $3 off amazon lol and needless to say they aren't really helping me. I tried picking 2 5200 american locks but I had to drill out those retaining screws. I didn't think I was ever going to get them open. So thank you sir

  3. Hey bill, just wanted to say thank you for this video. I picked an old American lock a long time ago and simply could not take out the core because of how gummy the screw was. After finally taking it apart and gutting the core I found that it had quite a few serrated pins as well as a spool! Now this might be that big a deal for a awesome guy like you who can pick damn near anything but I only recently got into lock picking and this is a big step. Thank you again for boosting my confidence and letting me salvage some nice pins!
