I reference to a recent Q & A on this forum, I just made this punch out board for silver strikes.
I used a hole saw "a little larger" than the silver center, then a larger hole saw to indent a space
that the strike will lay in to keep it from popping away...works great & took all of 5 minutes.
Not very pretty, but neither was my thumb in earlier attempts after some vino. A three holer,
just like an outhouse. See Pics~~~
