I can help.
I saw your post. I don't much that is really exotic, but I have a lot of old growth walnut, cedar, and even some Brazilian cherry. I bought it all from a cabinet shop that closed down. I am including pictures from one of four truck loads it took to pick it all up.
Also I worked for an orthopedic company who just happens to make hip replacements among other joints. As a result I have a bunch of old reamers and long drills used to hollow out femurs. They work awesome on wood. All are made from surgical grade steel or stainless steel. I have hollowed out a couple of flutes with them, and I am happy to pass some on to you if you are interested.
I like trades or cash of courset am willing to just hook up a fellow woodworker also.
