Dennis (Wider) did a Demo at his club a few years ago on Segmented Turning Processes, I'm not sure if this was your first or second Demo at the club Dennis but a DVD was made of it and he was kind enough to let me have a copy. I hope you won't mind me saying Dennis but it was very good and very informative with a few Blue Peter Moments (here's one I made earlier), so good on you and keep it up. Julian
