[QUOTE="Gord0, post: 1322935, member: 99696"] Just read through the whole post and this is why I like this site. People having a conversation and disagreement without acting childish. I'm not a gunsmith, just like to tinker. I am an engineer, and also a machinist in the aerospace industry. I deal with threads, a lot of threads. I've learned more about threads and thread failure than I've ever wanted to. Depending on the tool used to make the threads there can be massive differences in strength with the same thread size. Cut threads with a very sharp point single point tool and you have a stress point at the root. Add a small radius to the point and you have a much stronger thread. And possibly a different thread spec. Cut it with a die and get a completely different result, thread whirl it and yet another. The way the brake fits is another factor. The type and way the barrel was rifled will also play a role in the end strength too. Standard rifling that is cut vs button, vs 5r, vs 5c will all have different strength against bursting. There are so many factors in play that you would have to model every single thing and do FEA to see if you are in a good safety margin. I would guess that most gunsmiths don't have access to this. Something that a major barrel maker would. I agree with J.E. on this one. [/QUOTE]
