With your brace drill and a 3/8” twist bit, drill a hole about 3/8” deep 1”
below the bottom of the entrance hole. Cut off about 2” of a 3/8” dowel,
spread some glue on the end, and with your hammer lightly tap it into
the hole.

very long, we need to protect it with some finish. You can paint yours or
use a clear finish like a marine varnish. Either one will work fine.
