I built this with my kids in mind. I would love for them to show interest in wood working someday. The original gaurd was limited and well you know a pain. The frame is made from 2" square steel tubing welded together. The horizontal piece of wood is ash with a steel insert (painted white) where the adjustment knob screws down on it. The vertical piece painted white is also steel that connects the main arm down to the gaurd. This is the original plastic gaurd. I used a small piece of ash that runs horizontal to connet the vertical steel leg. It connects to the table saw with one knob and only takes a minute to remove it. Draw back are that it can't be used if I tilt the blade. I also added a shop vac hose over head which I connected using 2 clamps and a piece of wood using 2 small elastic bungee cords. This was a afterthought and I will improve in the near future. The dust collector comes out through the bottom. I hope someone gets I idea to make or modify there gaurd and hopfully prevent a injury.
