That’s really cool. I’ve been using chunks of metal and screwdrivers to use for those bending pins. I like yours way moreI was getting ready to bend the breech plug tang and was tired of doing it the same way I have always done it with a lead hammer and on a lead block. It works but is not a very controllable process in the greater scheme of things. So I stopped long enough to make these magnetically attached brass bending "bars" (for want of a better description). Brass 7/16" round stock is silver brazed to a brass arm made of 1/2" x 1/8" flat stock. A strong magnet is then screwed to the other end of the arm. These can be positioned easily on the vise and allow complete control of how much and where the bend occurs. Much better than whacking things with a lead hammer.
