yes I've come across his page as well, very inventive. I've had a couple of goes at making instruments flutes out of poly waste pipe psaltries using the pins salveged from an auto harp and several hammered and plucked dulcimers I've never spent more than about œ20 on them and sometimes Ive been pleased with the results, although I do have a tendency to "improve" them to distruction. I alvays tend to make 2 or 3 of each instrument the 1st. one is usually rubbish the 3rd one is "getting there" but then I lose intrest and go onto something else
