Vertical Cutting on Table Saw I don't ever remember trying to push smaller wood vertically through the table saw, but I do know others who got a big scare trying this. For as long as I have been using a wood router, I have known the value of using a much larger piece of wood as a support for ushering through the wood. I will also say here ... I do NOT love this idea, much better to use a vertical jig, like a tenon jig as shown below.
