I made a post earlier this week about buying a table saw. The one I ended up going with did not have a riving knife.

Where can I buy a riving knife for an old Delta contractors table saw? Asking from Canada.

Model Number? Splitters are available, but we need to know what you got… Delta made many different machines.

Timely topic. I need to get a splitter for my Ridgid R4512. When I google “R4512 riving knife,” I get third-party replacement parts websites. Are those generally legit?

No riving knife for an old Delta unless it is actually not very old. ( 2010 or newer ) Only a splitter. You can get replacements from several shops ( not Delta) or can go with a SawShark splitter and guard, DIY insert splitters or MicroJig splitters.

Here’s some Shark Guard reviews here: https://www.lumberjocks.com/reviews/brand/2018

I have a riving knife style one for a Craftsman Hybrid. I really like it, but for my saws design the knife is not removable for dado blades unless I take a lot of work to remove it. Not sure, I think I am going to call and order the splitter style so I can continue to use the guard.

What is the difference between a SPLITER and a RIVING KNIFE?

- Samdog

A riving knife is a splitter.

Splitters tilt with the blade, but are fixed in height.
Riving knives tilt and rise/lower with the blade.

They both serve the same function.

Brad

I couldn’t find the model number on the saw, I found the model number on the table though 422-19-091-2001.
That brought me to the 1994 Delta 34-444 Table Saw, which looks the exact same down to the antiquated toggle power switch.

Thanks, my guess is that I will be looking for a splitter in that case. Thanks to Brad, I now understand the difference and will double check by seeing if the bolt it attaches to moves when I raise or lower the saw.

I have a “pop-up” splitter on my Unisaw that, when I am about to make a non-through cut (with no kerf all the way through the wood), I pull the throat plate, pop the splitter down below the table level, and replace the throat plate (note that if I am switching between through sawing and dado or molding head, I have to change the throat plate anyway.) The pop-up splitter tilts with the blade.

Some splitters are affixed to the throat plate, and some of those can even be adjusted for non-through cuts, but they do not tilt with the blade.

The main advantage of a riving knife over a splitter is that because it changes height with the height of the blade, and in most cases, it tilts with the blade as well, once set for a specific blade size, you do not have to adjust or remove it unless you change to a different size blade. Therefore it is more likely to be regularly used, and thus safer.

That would fall under safety issue. Give DELTA Technical assistance a call 1-866-999-1499. Give them your model number or details, and query if an after market riving knive or splitter are available.

The complete OEM splitter assembly for that saw might prove a bit difficult to find, but you may get lucky if you look hard enough. And it is not only a splitter, but also what the blade guard bolts on to, along with some anti-kickback pawls. The actual splitter portion of it is part #422-04-086-0002 and looks like:

Because of the strength needed to hold the blade guard, it attaches in two places – just behind the blade, and at the rear of the saw. However, if you just want the splitter, you can cut the plate along the red dotted line shown in the picture and just use the behind the blade attachment point. In fact, you can pretty easily make one yourself if you have any metal working capabilities. I also remember one of the aftermarket manufacturers, maybe BORK, that actually had patterns you could print out to make it easier. Old saw blades make great splitters BTW, and can be cut easily with an angle grinder or Dremel tool with a cut off wheel.

Cheers,
Brad

I have ordered splitters from Lee at Sharkguard before and they are first rate.

I lucked out and figured out I needed a good splitter years back, so was able to get a Merlin Splitter for my Delta. It pops on in a second and pops off about the same, but you have to push a button, through a hole, using a screw driver, to remove it.

Since having it, at least fifteen years in, the kick backs attempted by my saw have been greatly reduced. A few times, like when cutting HIGH moisture content 2x’s for a friend, the 2x’s pressed against the splitter so hard I could barely push the 2x through [so I didn’t, of course].

Though it had gone out of business, I thought someone had picked it back up again. Regardless, the Shark Guard looks like it would be my first choice, if I didn’t have the Merlin.

It’s great to see people going down this road.

The splitter, when combined with a good push block/shoe makes cutting FAR less stressful. With the push block/shoe, even if something would have gone awry, I am able to push on through.

I cut my splitter/guard just like Brad described and it works like a charm. not hard at all to take off. Just a few twists of a 12mm open end wrench and it’s off or on. Wont rip with our it.
