The push stick is a very useful tool for the table saw where the ripping is too small to safely use your fingers to push the piece through. Simply it is a stick with a 90 degree notch out of it. This notch is rotated about 45 degrees so the stick is held at an angle. You can fancy it up with a curved handle or whatever.
You can click the small picture to get the full-size image and then print it off on your printer in landscape orientation. The length of the printed stick outline should be about 11 1/2" (29 cm). Use it as a template to cut your own push stick. The hole in the handle is so you can hang it up if you want.
