Title: Early Ketland Tumbler Questions
Post by: G Bekelja on December 28, 2023, 06:42:12 PM: So Chambers is closed until after New Year’s so I thought I’d ask here. This new lock had the cock not fully seated and the screw is stripped out most of its length. In the photo the screw is simply pushed in to that depth and then only gets a little less than a full turn to bottom out. I put a new screw in from a Siler and it only goes in halfway indicating to me that’s about where the threads are messed up inside the tumbler. I own taps but not a bottoming tap and I’m guessing that’s what would be required to restore the thread inside the tumbler? I am also unsure if the tumbler is too hard to tap without annealing and then re-hardening and tempering which is beyond my skill level. In the second photo I’m showing the amount of play in the tumbler between the lock plate and bridle at about .025” which seems excessive compared to other Chambers locks I’ve used but I’m not sure if that’s an issue or not. It seems like I need a replacement tumbler? I also need to dress the tumbler and inside of square hole on cock to get it properly seated but don’t want to mess with it if I need a new tumbler anyway. Thoughts?

I called Chambers and told them what I thought the problem was, that being a part of the internal threads of the tumbler not being clean. They thought so as well and said to send the lock back they’ll take a look and correct the issue.
