I have been thinking about getting better bedding in frozen ground so I got the drill out and put a hole under the dog and at the lend of the lower base plate. These holes will hold 9 penny nails. I'm using deck screws in the pic for illustrations. I'm going to tack some of these nail heads to the base and shorten the nails up a little so the are not so deep. Others I'm just going too place nails in if need for a solider set. I'm doing just a dozen to see how they work.
