David,what I have to say is,this is a stunning piece of woodturnery,and knowing when to stop turning when the wood starts making those creaking and cracking noises,shows you have experience enough to cope with holey bits of wood most wouldn`t even try to turn in the first place,wether its as thin as you`d like or not,I`ve founf its always best to stop when the wood talks to you,cheers,
Eric.
