Came across this article and thought of the forum. It is from Quinn Dunki, who has a channel, blondihacks, on YouTube where she does machining projects. She is currently making a small steam locomotive from scratch.
It is not a new article, but I could not see that it was posted here before. A friend asked her to help her with an antique mortise lock, and it took a bit of machining and brazing to return it to service: https://blondihacks.com/mortise-lock-repair/
