Keb...I use a duplex nail (2 headed) and cut the one off. Put the point on a grinder and round off top point. If the nai is to fat, then I carefully drill it to the size of the nail. If the hole is a little big, put extra epoxy in the shaft To glue them in I use epoxy. I use a flat toothpick to stirr and then let a couple drops fall into the hole. Then I roll the nail in the epoxy to get a little on the nail. Start the nail in. Rotate and pull/push in an dout till it seat. wipe off excess. turn upside down and set on some foil. Let set till the next day and wa-la
