Runar,
I have always disliked fitting a cock to a tumbler, and you have shown me a very simple way to get it done correctly!!
Thanks!
So very simple, marking as you did on the inside. Why this did not occur to me I know not!
Thank you again, and very crisp and lovely work you are doing.
Re the dog catch;
Yes, in Sweden they were used much longer than most countries. I have a Germanic lock with a similar threaded hole, but in my case the hole was for a tapered pin, so the tumbler could be set with less contact, to shorten and lighten the pull. It being on a rifle.
Best wishes
Richard.
