It's kind of ironic because I have thread going related to tool safety and I'm asking this. Anyway, I've never tried it, and don't really plan to, but I've heard of people free handing wood on a table saw. We were obviously forbidden to do it, but in high school my teacher told me that some of the guys who are experts at woodworking free hand, and they have a technique. He doesn't do it himself, but he was telling me that you follow the line and slowly pull the wood apart at the back of the blade.
I don't know if people actually do this though because it seems dangerous. I've free handed with foam board insulation, but that cuts so easy it doesn't kick back no matter how far I push it off the line, I've never done it with wood and don't plan too. Another thing my teacher told me was that he purposely let a guy go who was doing it because he needed to be taught a lesson, and the guy got hit in the forehead and was apparently never seen again (this was early 80s so people were a bit less uptight)
