I have an old Powermatic 66 and it’s got an aftermarket, Biesemeyer 78-441 type 1 spreader / kickback prawl assembly on it and I’m missing a piece to it.

I have the receiver assembly still mounted to the frame down in my saw, I just need the actual splitter/riving knife that clicks into it, part 1351644. If you also have the anti-kickback prawls, that’s great, too, but I really need the splitter/riving knife just for safe usage.

These parts have been discontinued years ago and I can’t find one. I know they also made them for the Delta Unisaw and some other saws and while they do look similar online, I have no clue if they are compatible with the version for the Powermatic 66.

Any help is appreciated! If you have one you don’t need, I’ll buy it! Even if it’s the entire assembly.

You mention after market, and here is a piece on them expressly for your saw.

This may be the place you want to check. But they will only have a splitter and kickback pawls. The PM 66 never had a Riving Knife.

If you are looking for a riving knife. I would suggest you get in touch with Lee A few years ago he was making some riving knife like splitters, and he may be able to get just the parts you need. Really nice guy too.

Good luck.

TherealSteveN, thanks for the reply. That big photo of the Biese unit in your first link is exactly what I have. That white piece with the black knob is already mounted to my saw I just don’t have the splitter with the kickback prawls. The next link you posted was a site I’ve been too and it is part number five that I need and they are out of stock. I have reached out to a number of places and no one seems to have them. I even thought about trying to get the specs for them and having one made on a 3D printer even if I had to trace it on paper if I could find someone’s to borrow and convert that to a different format. But the shark guard looks like it might be the way to go. Thanks again for the info! I’ll have to reach out to them and talk to them about what I have and see what’s available.

I have a PM66 and I think one of these splitters came with it. I’ll look in my shop and let you know.

Thanks, all. I couldn’t find anyone with parts so I finally went with the Shark Guard. I bought the 3-sized prawl package. I should have bought the blade guard, too, but I’ll do that later.

Dreban thanks for your post. I’m glad i read this forum since I have been looking for years to purchase the 78-431 which is made for a left tilt Delta Unisaw to put on my PM66. I assumed this spliter could be used for all left tilt saws not knowing that they made a version specifically for the PM66. Does anyone know the difference between the two 78-431 vs 78-441? They look very similar. Also, how do you like the shark Guard? If you decide to sell your Biesemeyer 78-441 splitter please let me know. Thanks again.
