I took a turning course about 10 years ago. We had a hunk of fresh ash. Rough turned it and then kept it in a plastic bag. Turned the bag inside out a couple times a day, and in a week it was dry enough to finish. The bag was really wet each time.
That was my last green wood; though I have turned about 75 bowls since then.
Two weeks ago I cut down 9" diameter lilac bush and the wood looked interesting. I am using the same technique as last time, but am not getting the same results. After 2 weeks the moisture has gone from 24% to 20%. The bag never has any moisture on it. I have even tried leaving it out of the bag for an hour here and there, but it is just not drying. (I posted a question on a gardening site about what had killed my lilac. One response was from a turner who cautioned me to dry carefully as lilac splits easily.)
Obviously I am doing something wrong. Any advice here?
