Riving Knife Adjustment
Вставка

- Adjusting the riving knife on your table saw is easily carried out.
As always the very first thing you should do before you do any maintenance or repair work on a table saw.
Firstly unplug the machine from its power source. Raise the blade then remove the blade insert or throat plate.
A good way to check the alignment is to sight down the length of the blade and you should be able to see if the riving knife is sticking out to one side or the other.
You can check to see whether the riving knife needs adjustment by eye. An alternative is to use a ruler. Using a ruler as a straight edge rather than a spirit level is because the ruler will go between the blade's teeth. The riving knife is the same thickness as the steel of the blade not the carbide tips and because the ruler needs to go against the steel of the blade and avoid the carbide, the ruler is the best option. If the ruler is on the carbide tips you won't get an accurate reading to the riving knife.
For the actual adjustment of the riving knife an allen key is the right tool. The riving knife has two directions of alignment, vertical and horizontal. Horizontal alignment is adjusted with two bolts
Vertical alignment is adjusted through a set screw located right next to them.
Because you don't know if your riving knife is correctly aligned vertically you need to check your horizontal alignment at the very base. To adjust the horizontal alignment loosen off the two bolts but not too much. It needs to be just tight enough that it will still hold steady when you move it and not wobble from side to side.
With it loosened off like this all you need to do is lay your ruler across the blade remembering to keep it on the steel and align the riving knife right up against the side of the ruler then tighten the bolts
After you tighten it up check it again because it does tend to move a little bit as you tighten the bolts. Also remember to check both sides of the blade
Once the horizontal adjustment is done you need to check your vertical alignment. The way you check the vertical alignment is by checking at the bottom and the top of the blade.
Mine is pretty well aligned at the bottom but the top has quite a gap
Tightening the set screw moves the riving knife to the right. Loosening it moves it to the left.
Once the adjustments have been done replace the throat plate back on. Check the riving knife alignment every couple of months maybe even more often. All it takes is a bad knock to the riving knife and it will push it out of alignment. - Навчання та стиль
Short and sweet and easy to understand, not a bunch of useless information thanks mate ill be doing this tonight
Thank you for posting this video! I have been looking through so many youtube videos and none of them showed how to properly align the riving knife!
This was exactly what I was looking for. Straight into it the how to with no bullshit! Thanks!
Thank you so much for this informative video. I just purchased an entry level table saw and the instructions were less than clear. Your video really helped me make sure my riving knife was properly aligned.
Thank you for that clear and concise explanation!
Thanks for taking your time with me today!
You just settled one of my biggest issues with my cuts!
Now I just need to be blessed with warmer WX so I can make my adjustments!!! Damn!...
Thank you VERY MUCH for posting this video!!!!! My table saw didn't come with a good manual & I am in DESPERATE NEED of aligning my riving knife!!! So, you've been a great help!!!👍👍👍👍
That was awesome and it seems easy enough to do. I just bought my first table saw (used) and it was missing the knife. I ordered it and just got it in the mail this week. Fixing to install now.thank you for making time. God Bless
Nicely explained - thanks
Thank you, THANK YOU. :) That's first thing I am doing next trip to the shop.
That’s a really great walkthrough. Thank you for sharing.
Thanks very much for this video.

Perfectly done, thank you
dude. you rock. thank you so much for making this video!
Thanks so much for your great instruction!. I got a Ridgid R4514 recently and my riving knife was out of alignment.
Thank you.
Fantastic. Thank you
Thanks Sir, This is exactly I was looking.
Thanks
Thank you for the info. You are a life saver, probably literally lol.
Thank u it was really helpful
Thanks saved me some trouble
Many thx!
My tablesaw has two set screws for the vertical alignment. Which of the two screws do I use to align the riving knife vertically? The saw its a Ridgid R4510.
Thanks....good video! DD
My porter cable blade slowly drifts lower after I set it. Is there a way to tighten it?
In the sawstop manual it says that the left of the riving knife should be flush with the left of the blade but shouldn't it be flush with the right side which is closer to the fence, then the RK is helping to keep the stock against the fence?
Which is it? Align flush with left or right?
Thanks.
Can someone from the SteelCity post a video overview of the new table saws?
There isn't any info on the net about the 45950G series.
i have it. 45925G. I will give you some info if you still looking for it
The lever inside where this part goes does it need to be down. I bought a display saw but the lever wouldn’t lock
I have a question I have a kobalt Table saw and the knob below the riving life has been missing for a long time what do you know where I can get a new knob or if I just tighten it up with the set screws arrive and I will be fine
For the Dado blades, should I remove the knife?
Each time I tighten my bolts down the knife moves am I being to aggressive ? I just fear that the dam thing will come loose during cutting, please advice!
How high should a riving knife be in relationship to the top of the blade?
What if it's clearly bent when stored.. how do you bend it back in place?
Any idea why locking the riving knife down has become very stubborn?
It is normal for a riving knife to shake after alignment?? I'm noob trying to learn how to adjust mine properly and stay safe.
I just cant fig this out ,, so frustrating ,, everytime i get the riving knife where i want it , its way way too loose , i cant get it tight or it goes way out,, please help
VERY informative. Makes you go HHHMmmmm. I didn't know that.

I never would have thought in a million years, that one day a neckbeard on UA-cam would actually teach ME something.... And for that I thank you !
A riving knife should be 1 mm proud on the left side of the blade and flush on the right - you've just adjusted a properly set up saw for no reason. On the left the cross cut is already finished by the time the workpiece touches the knife, its only aim is to gently nudge the workpiece out of the way - hence why it's proud. A flush knife is only on the right to fill the kerf and stop it closing on the blade. It should not be proud on the right - or even worse, shallow.
+Dr. Ralph Kennedy If this is the case, how do you explain his riving knife being level on both sides of the blade?
You say it should be proud by 1mm on the left and flush on the right. Meaning the riving knife is 1mm thicker than the blade. If this was the case, it would be impossible to get the knife flush on both sides, like in the video.
Mrhollerr You're correct, if it is the same width as the blade then entirely flush would be the best option.
Thanks
