Just took down an elm tree that was about 16" in diameter. Twas dead so it was a matter of when my back said go for it. Not a huge tree by any means but there is some good wood in it. Some of the trunk is hollowed out, but still good wood even there. Already have one bowl roughed out and drying in the kiln. Around Monday I'll be taking down a live oak tree and later a juniper that has a good trunk to it. Have some more hackberry coming soon. And, hopefully some red cedar. Still on the hunt for more pecan. Pickings have been real slim on that.
