Took a break from barrel inletting this week and case color hardened a couple of Kibler locks for a friend. Hardened and tempered, and yes Wayne, I had to "massage" the lock plates a bit to remove a slight warp. Top photo are the dry locks and the bottom photo are the locks sprayed with WD 40.

Looks fantastic. Any post- quench treatments? Oops just read more carefully. Tempered.

David you mentioned tempered. I assume an oven was used. What temperature if I may ask?

Looks great. Can you explain your process please?
Thanks

Very attractive and probably adds function as a rust inhibitor

Bryan, I have 2 more locks to case color harden in the next week. I wanted to photograph/document the process for a tutorial on these 2 locks, but since it has been over 2 years since I last did this work I needed to make sure I remembered the process. I also need to locate all my equipment and tools since I moved into a new work shop. I will work on getting a tutorial up in the next week. I plan on doing one of the remaining locks on Tuesday.

Rich,
One thing I did different is I used a 1/4" piece of square stock on screwed to the back side of the lock plates hoping to reduce the chance of warpage. What I did discover was that the 1/4" piece of square stock acted as a heat sink. If you look closely at both lock plates you will see that the centers of the lock plates are pretty dark blue, and there is a grey halo formed around the outside edge. This was an interesting pattern that I had not witnessed before when I did not use a strongback. On a side note, warpage, though slight, was about the same with or without a strongback. This makes me want to experiment a bit using shielding around the parts.

Thank you for taking the time and effort to make a tutorial on your process. I am looking forward to learn more about how to case harden and hopefully try my hand at it. Wyoming Armory does a fantastic job, but it’s pricey and I just want to be able to do it myself.
