I plan to make some pinned MTs for a workbench base after the design in Chris Schwarz’s Workbenches book. I thought I would use pin oak(of course) for the pins and have been looking for a source. A neighbor had a 4-inch caliper tree that clearly was dying and I asked him for it. I expected it might be infected with some sort of systemic fungus like phytophthora, and when I cut it down most of the heartwood and some of the sapwood was black. I don’t care about the color, but will contamination of this kind ruin the mechanical properties of the pins I make?
