So for example I can reduce blade speed without changing the motor speed, with the option of motor speed control too. eg 1:5 gearbox reduction and only 1:2 motor speed reduction -> 1:10 overall. But all that entails rebuilding the scrollsaw, which is probably OTT Joe --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
