Hi Greg, as has already been said, lucky ****** :mrgreen: . Some of it is good for turning, but NOT all.
The bottom half is not much good apart from fire wood IMO. BUT the top half where the branches came out can make some very unusual pots and bowls. Normally what you try to do is incorporate the ring of branch knots around the side of a bowl, or around the edge of a tall vase. The actual timber around the knots is quite soft, and very, very bland, or can look dirty with grey streaks running through it. I don't know, but have always believed that the dirty streaks are caused by not standing the pieces on end during the initial drying and the timber streaks like Sycamore. Which is always stacked on end for the fist couple of months if you want in to stay white.
Turning, it's a laugh. The white timber is so soft, softer than our pine. But when you hit the knots look out they are HARD, you must finish well from the tool because if you sand too much you will find the soft wood comes away and the knots are left standing proud of the surface.
After all that when the work is finished correctly the pieces look out of this world. One the wood is so scarce as being a garden tree you don't get 'em commercially normally. Two, they are a good talking/selling point on a stall especially to non wood workers.
PS - You can sometimes find a ring of knots beneath the normal branch line, but usually the knots get smaller the closer to the base of the trunk.
