Kemp......Here's the way they are made and used. You could use any small type brad. Cut the head off and chuck it into an electric drill, or drill press, then using a file, taper it like an old phonograph needle. You should then drill a hole in the
inlay that is slightly smaller than the original brad size. You then drive in this pointy brad until it tightens on the inlay,
clip if off with a wire cutter, then file flush with the inlay. They normally only go into the wood about 3/16" to 1/4". On
the last rifle that I did some restoration on, I found a small collett for my Dremel tool, that fit the small drill I was going to
use on some inlays I replaced. I must admit, I did glue the inlays in with some epoxy glue, I then drilled those small holes
for pins later. The high speed dremel worked great in punching a hole in rather thin silver inlays..........Don
