Another was an alloy tube with a piano wire wound around the ouside, this one worries me if the wire snapped, but if it works and the machine is shrouded.......what the heck...
another was 3 electirc planer spindles with disposable blades, all bolted together on a shaft as axle and fitted to a router, the max speed and balancing would seem critical to me, how would this be calculated?
Any knowlege of any form would be amazing!
