Not to deter anyone but I'll have to put in another plug for Dan Dreyers 'junkyard' hammer on the same site. Dan's hammer is the only home-made clutch-less mechanical I've seen that that made people stop in their = tracks and say 'Wow!' I like the way Dan thinks; get rid of the clutch and use = some modern technology, just like the kinyons. Does anyone have Dan's e-mail address? Thanks Mark
