Our old timey ideas on keeping people from loosing fingers and hands was two switches on the machine. One hand for each switch. The electric break was always engaged by way of a mechanical locking devise. If the electricals failed the cutter was locked or the punch press was locked. We had power feeds which all table saws should have if used for production work. It is my opinion that a hand fed table saw is not a suitable tool for production work unless it is power fed. with safty controls. I can almost guarantee that if you use one long enough cutting hundreds of parts at some point you will loose at least one finger. As a kid I worked at Owens yacht company building boats. You could always spot a wood shaper or saw operator, especially if they were older because they were all missing a finger or two. This was in the days before law suits:-) Doug
