For anyone who fancies jump starting a pipe making project; there's an unfinished set of drones on eBay at the moment starting at 99p:

I've no knowledge of or contact with the seller; nor any idea of the likely quality etc - caveat emptor applies!
Having said that .. I think I've seen much worse amateur sets although I find the style a overly 'brutalist' for my taste. This one is also slightly unusual in that it appears to have sleeved tenons (in the GHB style). Also worth pointing out that the 'Pink Ivory' (which is a wood) will lose some of it's hue over time but is certainly quite a pretty wood when finished.
cheers
