Re: table saw safety
Get real, you can't cut a curved or wavy line with a fence. A lot of freehand work is done like that. As far as the guard goes if you check you'll probably find the guard missing on a large number of table saws because the safety the American style guard offers is far outweighed by the inconvenience it poses. European table saws have long gone to the riving knife rather than the mickey mouse setup almost all American saws use.
