Bought a hard, maple blank for my 8th LR build and had the bbl and RR hole in and was starting to remove wood from behind the bbl....took a chisel cut and a 1/16" layer of wood lifted up. Seeing I had more wood to remove, I started the chisel and another layer popped up. Thought about gluing the last layer, but what about the next later underneath? So again started the chisel and another layer came completely loose. Never encountered this kind of maple again and didn't think it was suitable for a LR build, but . it made a couple of fires in my stove .....Fred
