Make a splitter for your table saw if it does not have one or you are dissatisfied with your current unit. This is an essential safety mechanism. My saw came without one and I soon learned the hard way, (wood shooting like a bullet across the room) of its necessity. A riving knife serves the same purpose, only it moves with the blade, whereas the splitter remains fixed in place.
Step 1: Steel
I have a Delta Model 36-678. There is a splitter attachment bolt inside the insert opening. Cut a piece of metal stock to the appropriate height and fit into this space.
Step 2: Drill
Drill a hole for the attachment bolt.
Step 3: Shape
Cut out a section of the stock so that the splitter is of the desired width.
Step 4: Kerf
Remove metal from the surface to match the kerf of your table saw blade. Test the splitter in place so that it holds the trimmed stock against the saw fence and allows the larger stock to pass all the way through.
Step 5: Attach
Adjust the splitter and tighten in place.
