That’s what you got out of Marks post? You might have a reading comprehension problem. I believe what Mark was saying is that welding up or adding a piece of metal to something that needs .001-.002 when you can move the metal using tools is unnecessary and potentially more intrusive and detrimental to the part than the peening. Not to mention the time it’s going to take to fit the parts back up.
So again, you don’t know what you’re talking about. You do realize that some of the guys that have commented on here are actually working professional gunsmiths, pretty highly regarded in the business right? Have years of actual training, experience and real hands on know how? Taking the time out of their day to explain what is a universally accepted method is…..And then there’s you.
