Good luck Neil. I'd be sorry to see that one distort - it looks pretty damn fine just as it is. Have you considered the Hodgson Hot Wax approach?
To be honest Phil I love to see these sort of pieces move. Saying that I will be doing some demonstrations next year and have spoken to John about showing his method in some. He and Jenni are likely to be at Harrogate this year. What with them, the Halls, and the Greenwood's things are likely to get messy!
