The tapered square punch is such simple solution once you know, been picking up the gun and looking at it all day and I'm pleased as punch ( excuse the pun ) I really think there is a need for a "how to" or DIY section. There are many of us that enjoy restoring old pieces of equipment and there should be a thread so people can share knowledge and expertise more easily to help us all expand our skill range. Like with barrel browning and blueing it allows us to perfect a technique and pass skills on.
