    What do you do when putting on a dado blade



  2. MelLaMarMinistries on May 5, 2022 at 6:59 pm

    Thank you! This totally answered my question!

    I have a Dewalt tablesaw which has a riving knife and a blade guard. Which of the two should I use since it does not appear I can use both?

    I clicked the like button as soon as you said safety.
    Thank you for the professional explanation.
    I am a 20 years plus machinist, I can’t thank enough for my professional teachers and colleagues for giving me this kind of wisdom.
    I never had any accident with the milling machines and we did work long hours 10 hours into late night till 2:30 am year around or 12 hour night shift for several weeks.

    Thank You !!!

    Hi there! Great video. I understand now what a riving knife does. Why would a person need to slide the knife to a lower position? It seemed like your explanation was the same



  7. Ross Lindley on May 5, 2022 at 7:03 pm

    Hi George. On the Bosch 4100, what is the principal/purpose behind lowering the riving knife to the lower (middle) position when making a "non-through" cut? I don’t see what difference it would make.



  8. jonathan kohl on May 5, 2022 at 7:03 pm

    Where do you set the riving knife when cutting all the way through the board? Do you only set the riving knife above the blade when you’re not cutting all the way through the board?

    I am confused. Is the black thing a _splitter_ or a _riving knife_ ? From the start of the video the presenter kept referring to a splitter when point at or touching the black thing and I was waiting to see the riving knife. I have never owned a table saw, (unfortunately I was rubbish in woodwork classes) and the only part I really knew about was a fence. I realise this was made 9 years ago (damned good video quality for that time) but it needs to be dumbed down for dummies like me. Now I need to go and watch another video to find out what a splitter and a riving knife are because this video has left me none the wiser. I appreciate you publishing this video but it missed the mark in my case.

    I gave it a Thumbs Up because I feel that is sort of the payment I can make for watching the uploaded comment. Thank you.

    [UPDATE] Ok, the black thing was the riving knife. Now I just need to find a video on what a splitter is. Fairly self explanatory but I need to be sure especially around a spinning blade. Also learned what a curf, kurf (or however it is spelt) is. Due to the different language between the presenter and me, I wasn’t able to fully understand the word that was being spoken. I am an native English speaker but I am not English. No, I am not having a go at the presenter. It is just many countries have their own way of saying words. The classic one is Americans pronounce herbs as _urbs_ as in suburbs and do not use the letter *h* in the word. Not a big deal when cooking but can be dangerous when Mr Blade doesn’t appreciate the learners naivety due to mishearing something important about safety. Again, Thank You for this video. It has caused me to look at other videos to resolve any safety questions that I have now become aware of. 👍

    Excellent explanation.



  11. Ray C on May 5, 2022 at 7:04 pm

    Excellent safety information for beginners! (And a nice reminder for the rest of us.)



  12. Brian Pshyk on May 5, 2022 at 7:04 pm

    Why did you lower the knife down at the end of the video?



  13. Brian Williams UK on May 5, 2022 at 7:07 pm

    Your description is perfect not like Eric Sorensen who gives advice exactly the opposite to yours, very dangerous.



  14. xxDrain on May 5, 2022 at 7:08 pm

    Thanks! It’s really useful to have a better understanding of all the parts when translating for power tool manufacturers.



  15. Monto22 on May 5, 2022 at 7:09 pm

    Totally newbie here. While using the splitting knife is it normal to feel some resistance when feeding board? I feel my board too tight against the fence, and I need to push it, and this worries me



  16. Robert Lavoie on May 5, 2022 at 7:11 pm

    Yes but, with a thin kerf blade, the riving knife is wider and it pushes the wood against the fence and it jams.



  17. bricofast on May 5, 2022 at 7:13 pm

    Bosch GTS 1031 has the best Riving knife 👏👏👏



  18. FreeSoftware on May 5, 2022 at 7:14 pm

    01:33 "Eating wood for dinner" – Hiiii..haaaa. A humor almost as black as British humor. Ok – did I get this right: whenever the two pieces run *non-parallel* there is [without a riving knife/splitter] a potential danger of a kickback?



  19. George Mcmenemy on May 5, 2022 at 7:14 pm

    Finally a clear precise understanding of there function. Thank you



  20. submissions72 on May 5, 2022 at 7:15 pm

    Thank you!



  21. Pablo S. Cargoe on May 5, 2022 at 7:17 pm

    Groucho lives! Yay!
    Thanks for the info, nice video.



  22. 738polarbear on May 5, 2022 at 7:18 pm

    I have noticed that the majority of demonstrators on you tube have removed riving knife and anti kickback pawls on their saws.I am glad you produced this vid although I fear your advice will fall on deaf ears



  23. Axell on May 5, 2022 at 7:19 pm

    have a circular saw with a splitter. its an old saw. I,m not sure if it is positioned right. the top of the splitter is aligned with the blade but the bottom is a couple of millimeters from the blade. is that supposed to be aligned this way?



  24. Remie50 on May 5, 2022 at 7:20 pm

    Thanks for the video. What kind of Jackass gives a down vote on a safety vid like this?



  25. Fernando Oliveira on May 5, 2022 at 7:21 pm

    Very well explained! Thanks for sharing!



  26. Tornado92 on May 5, 2022 at 7:25 pm

    didn’t know what a riving knife was until it was too late



  27. Pauley We atwhere on May 5, 2022 at 7:31 pm

    Fantastic explanation and to the point, thanks



  28. MikalZ on May 5, 2022 at 7:32 pm

    Great explanation and great video quality. Thanks!



  29. Steve is Rome on May 5, 2022 at 7:36 pm

    Brand new to woodworking and so glad I landed on your channel



  30. Chris P. on May 5, 2022 at 7:36 pm

    It would be helpful if you could add info about how to purchase a riving knife. Are there universal ones? How do you put it on? What do I have to know about my saw in order to choose the one that fits my saw? I have a brand new, never used portable 10” Delta saw from 1997. So I’m hoping there are universal knives available.



  31. Aaron Williams on May 5, 2022 at 7:37 pm

    A Belt and Suspenders!



  32. Designer- Garb on May 5, 2022 at 7:37 pm

    good safety information will never get old, thanks for sharing, I was considering removing mine as sometimes it does not line up with the blade and i had no idea of its purpose, I know better now. thanks



  33. Jane Mahaney on May 5, 2022 at 7:37 pm

    I just got a DeWalt table saw. When putting it together, reading directions, I installed the guard. But in looking at rest of directions, it says not to install both riving knife AND kerf. Now that’s what I have. One was already installed there. NOW I can’t get it out. Any ideas for me, a beginner? I want to start using, and I’m reading over all directions. I want to be safe, but I know it isn’t right with both there. I flipped the latch on side but it won’t release the guard.



  34. Gregory Bryant on May 5, 2022 at 7:40 pm

    Yeah. Took mine off yesterday because it was easier to pack in my car. Used it today without it and was nearly given an appendectomy by an almost cut off piece of 1/4" ply. I was lucky. Needless to say It’s back on now.



  35. Larisa Ulkina on May 5, 2022 at 7:42 pm

    I want a riving knife for my Makita table saw.



  36. Shun Wong on May 5, 2022 at 7:42 pm

    Hi, what is the brand and model of that table saw you have in the video? Is it a Bosch?



  37. Farad Packedel on May 5, 2022 at 7:43 pm

    thank you, finally someone says what riving knife is!



  38. N Holt on May 5, 2022 at 7:44 pm

    Great video. I need to get one for my table saw. I always stand to the side of the wood as I"m pushing it through, NEVER in front.



  39. Alex & Erika on May 5, 2022 at 7:44 pm

    1:30 "Eating wood for dinner!" Great informative video!



  40. T J on May 5, 2022 at 7:44 pm

    Great info!



  41. vince King on May 5, 2022 at 7:45 pm

    I am still a little confused about the difference between a splitter and a riving knife. The anti kickback thing without the teeth would be useful. Great video



  42. Tom Tomlin on May 5, 2022 at 7:47 pm

    Thanks that was helpful.



  43. Mohamed Naeem on May 5, 2022 at 7:48 pm

  46. Smiley Sixguns on May 5, 2022 at 7:51 pm

    My table saw has had a version of this on it since I bought it but I didn’t realize what it was actually called. I understood how it worked and why it was there but not the name.



  47. Louis Caso on May 5, 2022 at 7:55 pm

    Great explanation! You would make a super teacher!!



  48. Mark Blount-Stonham on May 5, 2022 at 7:56 pm

    Now I know. Thank you 🙂



  49. Scott Griffith on May 5, 2022 at 7:57 pm

    After once having a 2×4 almost impale me (had a nasty bruise on my belly)I can fully appreciate the riving knife feature on my new table saw.



  50. gussy on May 5, 2022 at 7:57 pm

    You started the video by saying you would explain the difference between a splitter and a riving knife. I waited for the explanation but nothing happened.
