Hi there... I am the bloke who welded up that weird thing?... back in 1996 Then when the windmill turned it drove the shearers arm and he sheared the V8 sheep between his legs... the whole thing wieghed in at 7 tonnes and was made from farm scrap... all weld construction.. The shearers head is a beer cask, the windmill head was made from 20 ltr chemical drums... I lived in Ongerup, but now live in the philippines ...cheers Don McDouall
