I cut 2 nice American Hornbeam 3 inch saplings, and axed one down to put it on a caul to shape it.When I got to the middle of the sapling Ants had tunneled through the core wood.Deep enough so that I can,t get a bow from it.The Ants were coming out of those tunnels. I have built quite a few A hornbeam bows ,but never witnessed this before.Strange to say the least.
