I thought I would share this since it has been successful. It goes without saying extreme caution must be exorcised doing this.

I just saw kerf splitters in a catalog.I made my own.
I took a piece of oak and milled it to fit in the saw table blade opening.
I then started the saw with the blade all the way down.
I held the insert in the saw while cranking the blade all the way up with the insert captive in the opening.
After the slot was cut, I extended it with a hand saw.
I made a wooden splitter and glued it in the slot behind the blade.
I have had the splitter on the saw for about 15 years and it still works.
I have not had any mishaps.

I held the insert in the opening with the rip guide while cutting the slot.
