Walt,
I think maybe I recall that from one of your books? For putting a roll pin in the lower band on the Garand, maybe? I have a couple of pin vices, but mostly I use the drill chuck handpiece on my Fordom tool to hold those things. I just hit the foot pedal lightly to turn the end of the pin against the side of one of those pop-in fiber-reinforced cutoff wheels running about 1/3 speed on a Dremel tool.
I'll see you during High Power. My dad and I will be up there at least part of the time. He's having foot trouble, and doesn't walk well at the moment, but we both want to see if he can manage at least the Garand Match, even if he isn't up to the regular matches this year.
