Quite often you'll see people taking the waste of a joint like a large housing or lap out or something using the table saw, usually as quick as possible back and forwards over the blade with just your two hands on the piece of timber, also cutting on the reverse stroke as well so it pushes the piece back towards you, bit like a climb cut on a router bit.
I've also seen people trying to cut very gradual curves with a table saw on site before, for some kind of cladding if I remember correctly, definitely no riving knife or guard. Seen all sorts of crosscutting and ripping with no fences or crosscut devices.
I can't say anything though as I'm currently guilty of the no riving knife and guard combo and also doing some very dodgy cuts . Ever had a full-sized Welsh dresser on the table saw to cut 3" off the upstand on the bottom? :lol:
