That is a beautiful piece of work. The dedication, patience and skill that went into it really are something!
On a lower note. When we lived in Stroud our neighbours daughter was training to be a jewler and I was asked if I could make her a jewlers bench, just like the bench he was using to do his fret work on. That was a nice commision and she is still using it as far as I know. I had to make several 'anvils', the small vee shaped part that he was actually sawing in, because as they are the main working/cutting part they get worn. `it's fascinating to see just how it is used!
Thank you for the link, but it's made me very late for my bed after a bleedin hard day trying to find a water leak in 50 yards on mains water pipe in our garden!
