Powermatic 68 Riving Knife

Greetings,
I'm fairly new to woodworking and recently acquired a Powermatic 68, which is a beast of a saw. However, it was missing a riving knife or splitter of any kind. Searching around online has not yielded much help, so perhaps someone here can help. Are there any aftermarket systems out there that can add a riving knife to my saw? I would preferably like to have a system that raises and tilts with the blade. If nothing is available, does anyone have guidance for making one?

Welcome to the forum!

Here is the manual for that saw:

http://vintagemachinery.org/pubs/655/4427.pdf

The part number for the splitter assembly is on page #23. (Part # 2250154)

The parts diagram shows how it attaches to the saw.

Thanks for the response, but the problem I'm finding is that no one manufactures the replacement anymore. That's why I'm looking for something aftermarket.

A Shark Guard www.thesharkguard. com may be available for it. If it does, you will have one of the best splitter/riving knife sets on the market, and get an easily removeable blade guard as well. It's worth checking into. I found a Unisaw first, so I quit looking for a Powermatic. It came with a pop-up splitter and I found a ceiling mount Brett Guard for it, so no need for me to look any further.

I have that saw

There was a splitter installed on mine not a riving knife. The splitter also carried the blade guard(s) and anti-kickback pawls. I ended up replacing it with my own design, a simple flat plate.

A riving knife would be preferable, but you may have to make your own. You could copy the idea of a Shark Guard and adapt it to your saw's dimensions OR see if he makes one for a 68 Powermatic, OR if you give him the critical dimensions he may make a custom one .... who knows?

Page 22 of the PDF show the factory splitter, part number 20:

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
