You can try and contact Pete at Viable Lumber. I visited his place a few years ago on a trip to St Pete, FL. Brought back a small pickup load of camphor, rosewood, norfolg, and red eucalyptus. A couple years ago I ordered and he shipped some monkeypod to me. Shipping at the time wasn't cheap due to the weight and shipping to northern Indiana. But I made two big urns from it for some family members.
I haven't needed needed anything from him in a while so I don't know if he still ships or not. I don't know if he still does Symposiums, but my understanding is he used to take wood as a vendor to them. While walking through his warehouse with him he said he didn't have a lot of free time for turning he did have a PM3520B in his warehouse.
Viable Lumber salvages urban trees in central Florida and gives them a second life as art, bowls, furniture, custom woodwork, live-edge slabs, bar tops, musical instruments and more.
