Pat, the knot was concealed until I started to rough out the limbs The wood around the hole is sound wood but I cut right through it unknowingly when I was removing limb wood. the only evidence of the knot from the raw stave was a slightly proud lump on the back but its very subtle. Im gonna try the Titebond III and saw dust and see what happens. Im done fiddling with it for a few weeks until it dries out some. Meanwhile my quest for a nice hickory tree is still unfulfilled. I have ash, black gum, black cherry, white and red oak, maple of several varieties, birch, beech, black locust, white pine, cedar, hemlock, and a bunch more but I cannot find a single hickory tree on my land.
