Faaark! Looks like a clever invention, but be buggered if I'd be game to try it out. There's some phenomenal forces being absorbed by that blade when it shuts down - i wonder if it ever flies apart instead of just stopping? I've seen the results of a saw blade busting, and it was far from pretty. A mate spent some months in hospital with micro-surgery re-attaching the tendons and muscles in his arm after he had it sliced to the bone from a busted blade. And he wasn't even operating the machine, was just in the same shed. He was lucky that it only sliced his arm as it went past. Deliberately jamming it while turning is just asking for trouble. Surely there's another way - retracting the blade for example. > > PhilD > > -- What is the difference between a duck?
