I didn't want to make a zero clearance insert again for my new table saw, precisely because of the airflow issue! I wonder why I never had this so simple but brilliant idea to simply drill holes in it? You made my day, thanks a lot!
Denis, I posted a comment but it seems to have disappeared!!! Anyway, this was the first insert that made sense to me, from an airflow perspective. I made one quite similar to yours, and was going to send you a pic here, but i dont see any way to do it. I made it out of Corian, and it works so well, i really dont need to use my hood on most cuts. Just wanted to say thank you, and that I learn a lot from watching your videos. Keep em coming, as some day I want to start making some videos too, just getting my shop to the point where i can and not be embarassed!!!
Ho Kent, I know i saw your comment. It was good to read that your table saw benefits from the insert. Good luck, love to see your channel. Most important part is beginning. And when you want to make your workshop better first, welll let that be one of your first videos. All the best. Dennis
Awesome video. i've been frustrated trying to get better dust extraction and was trying to basically seal off everything. It never occurred to me that I needed some holes to allow more air flow. This has made such a big difference for me. thank you very much for sharing.
Thank you for your efforts to develop the insert, and your generosity in sharing it. I'll make one. On a different issue, I've noticed in your videos that you prefer black surfaces. Well, I have found that when I got older in age and my vision is not as sharp as it was, that I prefer bright colors. Also, when I've refurbished tools, I paint the inside and undersides a bright color. This makes it easier to see if adjustments are needed at a later time.
Very nice video! As an engineer, I very much appreciate your thought process and experiments and the use of "turbulence" word!. The sealing/not sealing thing is the same as with olive oil or drinks in a can. With air entrance, it will always flow much better, with a higher flow rate. Thanks for the content!
Hello Dennis, just found you on UA-cam I must say how you come across very professional in your video's and you do not do it on the cheap. Please keep doing what you do best I love your channel subscribed and liked keep up the good work looking forward to your next video
I really enjoy watching your videos! The review of what you like and don't like about the tools you use are also very helpful! keep up the good work and great videos! Mike
I want to add that I made a new, zero clearance insert I added slots on the left side of the insert just like yours and dust collection is better! Thank you. 😁🛫
Amazing. What a great job, buddy! Keep on keeping on! I have just started this new hobby of woodworking and every bit of a great video like yours helps. Thank you!!!
Dennis, I will comment in the WW forum but the only problem with air entry through the insert plate is there is no air entry when the whole plate is covered. If a drop down shield was attached to the side overhead guard and pulled down on occasions when the cut produces side deflection of the debris then that problem goes away. I think your insert plate is an excellent idea if air can get through it. If I am cutting thin strips I place a piece on MDF on edge beside the blade and the debris deflection does not occur. That is the best demo of why a cabinet should not be sealed that I have ever seen, good work and now a lot more people might understand that sealing a cabinet is the worst thing that can be done. Keep up the good work, your videos are fantastic.
Hi Chris, I just uploaded the video on the forum. I understand your comment, and you are right that it only benefit if you do not cover the holes. But in most cases, the least thing that can happen is that you get a better ability to clean up your cabinet saw. (before and after the cut) And the insert is an additional hole. Like you also agreed you should not cover the holes from your cabinet. So, when the whole plate is covered, you end up with the same situation you normally would have.
I made my insert similar to yours. I'll probably make another based on your suggestions. One problem I had was dropping a set up bar into the slot and it falling into a very inconvenient spot inside the saw. Another design of mine was to drill holes at each flange location. I inserted set screws in each hole and could adjust the height of each screw with an Allen wrench from the top of the plate. It's a lot easier and quicker than removing the plate to make adjustments.
Excellent design and function; very well thought out. I knew about the airflow requirements for HVLP systems with my router but never gave the tablesaw much though. It always annoyed me that there was a pile of dust in the bottom of my saw (I'm using a two stage system with a 2hp dust collector, shop made Thien baffle and overarm collection on the blade). I made a zero clearance insert (including a hardwood riving knife since my saw predates them) today using your design and I'm very impressed with the results. Way more efficient; this was a game changer. Thank you sir.
Massive thanks to your great vids. I have the same saw and after watching your vids my dust extraction has improved so much. Great idea for the insert I have drilled holes in mine and it has improved it
Thanks for showing your ideas so clearly. I‘ve got an Axminster sawbench which was verry open underneath. So I closed the gaps under the table to increase the airflow. With my zero clearence insert of alu (4mm) I ve got a peeping sound. So I have to make some changes to avoid vibrations. Your videos are very inspiring. I love them! Greetings from Vienna!
Dennis just found your channel and Wow! Great videos and it’s weird to say but that’s a beautiful saw insert. I will be making mine soon! Keep up the informative and high quality videos. Hopefully you can get some more subscribers because people are missing out!
Thank you for the great idea. I am dissatisfied with the dust control of my current zero-clearance insert and this seems like a wonderful solution. One suggestion though. At about the 11:00 minute mark you are getting the saw kerf cut into the new insert. You run into the problem of getting the insert exactly in position to cut the saw kerf. Instead of cutting it most of the way through, why not install your dado blade, which usually smaller than the normal working blade, put the new insert in place, move your fence over the insert - not over the blade though - to hold it in place. Then you can raise the blade to cut the kerf. Then you can reinstall the normal sized blade and continue.
Well done Dennis. I really enjoyed your video on your channel. Tks for sharing with us. I have been a fan . Hope to have my work shop up and running soon. Can't wait to see what you think of your hammer upgrade ☺
What an excellent idea! Next weekend I'll modify my insert as well. It's great that you share this with the woodworking community instead of patent it 😃
Great Idea and really good video.Just inspired me to build one of my own.When I saw the cuts you said they are not necessary,I had the idea for my version to cut them in most used angles for mitercuts 15/30/45 and so on and then just put a strip with same wite of the sawblade to aline the fence more easy for cuts in angles.You inspired me.Thank you
Hey.I’m going to build 2 or 3 for my table saw now and my saw has more space on the left than on the right in the hole.I ordered phenolic resin or pertinax.Is that the material you used for yours?i found coated plywood or “Siebdruckplatte” here in Germany to weak and deformable.But all ready the “prototype” was way better.Thanks again.
This is the most comprehensive and rational explanation of making a good zero-clearance insert. Thank you for taking the time to make this excellent video!
A guy on the delta table saw group makes and sells them for the delta. It has interchangeable cartridge that so you can set up all the different angle cuts and still have zero clearance.
Hi Denis. I love your insert. It's like a piece of art. What do you think about milling the cast iron top to continue the grooves over to the miter slot? It would be quite an undertaking, but would allow the air to continue flowing when cutting a piece that covers the insert.
Great idea Dennis. I must confess that I first thought the shallow angled kerf cuts across the top were to allow a little airflow under the workpiece, not just for aesthetics! You mentioned about not putting holes in the right hand side as this would increase friction on the moving workpiece. This got me thinking whether a version made from material with a low friction surface, like melamine faced MDF or phenolic faced ply might be either a way to also allow some air holes on the right hand side or just reduce the friction of your current design. Just a thought ...
Hi Stephen, My insert does not has that friction on its own. If it has, it is a bit from the suction. And you are right about the cuts across the top. I planed this so it could release pressure to the sides. But, the impact of the suction is very limited because there are enough holes where your dust extractor can get its air from if you cover the holes of the insert. Different then with my router table box. This one is airtight. If I put wood on these suction holes, it is difficult to put your wood over it, that is why I did a sliding door, if it can release the pressure the problem is solved. That is the "normal" situation. So to be short, this is almost a "non" issue.
Very interesting video my friend. I will save this video and watch it again later because I'm going to try it on my table saw too. Thank you for sharing my friend!
Hi Chris, Thanks, watch almost all of your video's and I like them a lot. There is only one thing I think you can improve. Every time I see you use your table saw, this thing is so unstable. That this is the only thing I can mention is meant to be seen as a big compliment. I hope to reach your filming and editing skills someday. Thanks for your comments. Dennis
Dennis, your English is great, my dutch is non- existent. Your videos are great, minor pedantic point, clearance is spelt with an 'a'. Otherwise brilliant!
Superb content Dennis, loving the whole china series, as well as your workshop tours, and builds. Can I ask the make of your table saw, and also the sliding extension, they look really good!? Thank you, from the UK.
Hi Michael, The brand of the table saw is from Harvey. But I think it is the same as the Axminster Trade table saws from the UK. The sliding extension is also from Harvey. Axminster Trade uses a different one. Thanks, Dennis
Hi Jay, I just want to say that I am very happy with your comment. It feels great to inspire people. That is very motivated for me to read. Good luck ad I hope you will be happy with it. Thanks Dennis
I took a different approach, I use a zero clearance insert, I have 150mm bell mouth sucking out of the cabinet table saw body, but opposite that I cut part of the cabinet open, fixed heavy duty mesh, this allows dust to be easily pulled across the cabinet. I have done this for 6 months and yesterday wanted to change a belt, upon opening the babinet there would have been enough dust to fill a coffee cup.
I love the relief cuts you made on the top surface of the insert, I assume they are meant to stop the air preasure from your dust extraction system from sucking the work piece down and creating too much resistance .
Yes, that was the thinking. Of course the wood is sucked to the holes, but that is not a problem. It is not that strong because you should also have some holes in your cabinet. So when all the holes are covered it just extract more air from those places. However, I think it helps a bit. And it looks awesome! :-)
Looks great!! As I don’t have a table saw or anything I like watching these videos. Have you ever considered the direction of flow for the air inlet? Or adding another small inlet on the side to help the dust rotate from the bottom up into the hose? Just an idea!
Hello Dennis, did you ever check, if your "box" in which the saw is turning is actually so well sealed/air tight, that without your extra air-inlets on top, the airflow in the box is actually insufficient ? Otherwise it could be that the air-circulation under the table influences the airflow of the overhead extractor (and the other way around.), like 2 dust extractors with inlet hoses connected. I made 2 extra inlets in the zero clearance insert and have the impression, that things didn't improve for me if I use both extractors. If I only use the extractor that clears the box, things did improve probably a bit with your additional inlets. I did a lot of thinking about this and came up with the following: I checked my cabinet-box, and found, that there are a few openings in my table and the surface size of these openings seem about to correspond with the surface size of the extractor hose. If you have too many openings (as I now may have) extraction-speed (and strength) are going down quite a bit, so perhaps it is a good suggestion to first check this. what say you ? Best regards, Karel
Hi Karel, Your cabinet should not be, and probably will not be air tight. It has to cool the motor, but It needs air flow. But of course, you have to check if something is helpful. When I use my overhead dust extractor, I do not find any problem with dust. You understand your point and it was also my thinking. But most of the time, the wood is covering those holes in the inlet, so then the overhead dust extractor gets extra power. So, no extra dissedvantage in that case. Most benefit I get when I want to clean up edges, and cut away small amounts of wood at the sides. And when you can not use your overhead blade guard, than it gives a lot of benefits. SO, in my case I an not find any disadvantage. Dennis
i'd be worried about the diagonal slots potentially catching on the edge of the wood and pushing it sideways or getting chips caught in them that could lift and tilt the wood.
Extremely interesting video. I'll be making this for sure. Can you tell me what type of set up you have for your drill press. That hold down looks so effective. I don't know how many times I needed a 3rd arm to best drill a hole. TY
Hi, that clamp comes with this Bosh drill press. It is indeed a nice system. I do not have the bosh anymore so I implemented a rail in my drill platform where I can slide a clamp in. Works perfect too.
Beautifully done. I also like your attention to detail and design. Your shop is amazing. Question, I am still not sure I understand why only the left side needs slots. I would imagine both sides of the blade would get sawdust? I know you found that out from your test I must have missed exactly why.
I have a question, so what about when you are using the miter gauge vs the fence? You could very well be using the left miter slot so the waste drops the right of blade - wouldn't then you need holes on the right?
the slots have two functions. To clean the cabinet (if you have a cabinet saw) and better dust extraction. For cleaning the cabinet it usual creates more air volume and because this is normal a bit limited it will clean the inside of your cabinet better. It does this before and after the cut. For this, it does not matter where the holes are. Second is better dust extraction during the cut. When you put holes at the right (when the fence is at the right) the holes are covered with the timber you are cutting. So, you need it at the other side of the blade. It is most effective for cleaning up edges when the holes are open during cutting.
@@HookedonWood haha and I just got done immediately filling in the holes I had on the right after watching the video before I thought of that I think I will leave as your design and see how it goes. Another thought is obviously if you use a sled then nothing works... Unless! You also put similar slots in the sled? What do you think about that application? Or maybe instead put an overhead suction over the sled. I know I am ovetthinking but sort of fun! (esp during covid)
Hi Worskin, Your thinking is not that different from mine. If you watch Episode 14 you see at the beginning that I made a finger joint jig. You see I made a slot in this for better dust extraction. I think it is a perfect solution because especially with a sled, the dust blows right in your face and when you make a slot in it, you reduce this by 80%. At least that was what happened with my finger joint jig. I would recommend making it longer than I have done.
This is probably the best dust extraction explanation i have seen, thanks for sharing.
I never thought looking at a table saw insert the word beautiful would be in my thoughts. 😍
The world needs more men such as you! Brilliant design and insight into an overlooked system!
Thanks Cal,
Appreciated!
Incredible analysis, design, testing, and execution. Better than professional.
Brilliant my friend. Incredible explanation of dust control in general with the bonus of an awesome zero clearance plate. Thank you.
Feels like I am listening to Arnold. Great video sir.
I didn't want to make a zero clearance insert again for my new table saw, precisely because of the airflow issue! I wonder why I never had this so simple but brilliant idea to simply drill holes in it? You made my day, thanks a lot!
Thanks a lot for your kindness. Always a pleasure to hear from you and learn great tricks or gigs.👌👍🖖
Thanks James, Always a pleasure to hear your comment.
The Eddy Van Halen insert.... love it!!! Great idea, yes, patent and sell them!!!!
Nice design and I love the black MDF, I've not seen that before it looks really nice.
Love your approach to experimentation and learning. Also: Really refreshing to hear a European accent discussing woodworking in the metric system :D
Very insightful regarding have zero clearance but also letting air in. You exhibit a unique combination of precision thinking and aesthetic vision.
Thanks for your comment and compliment. Keeps me motivated!
This guy is super awesome, I buy a lot of quality stuff. Thanks for saving me money.
Nice update and a fantastic way to show how to make the insert. I love the editing on this. Thank you
Thanks London,

Hi Fred, That is another way. But, I do not have a dado blade. But I find this way much safer and I manage to get the cut right where it needs to be.
Nice tip on plugging or opening the gaps on your particular table saw to create the optimum air flow!!! Genius. :-)
Thanks Larry
Absolutely brilliant!
Super smart. Well done. Thanks for sharing. Do you have a vid for dust extraction for your mitre saw?
Excellent video and process. Thank your for sharing.
Beautiful! Thanks for sharing.
Great Insert! I just finished mine. I´m thinking about upgrading them with your extra slots.

I have done this for 6 months and yesterday wanted to change a belt, upon opening the babinet there would have been enough dust to fill a coffee cup.
In the End, it is the results that count. Nicely done!
Great idea... and very informativ video 😍💪
I like your style.
I love the relief cuts you made on the top surface of the insert, I assume they are meant to
stop the air preasure from your dust extraction system from sucking the work piece down
and creating too much resistance .
Yes, that was the thinking.
Of course the wood is sucked to the holes, but that is not a problem. It is not that strong because you should also have some holes in your cabinet. So when all the holes are covered it just extract more air from those places. However, I think it helps a bit. And it looks awesome! :-)
Beautiful! Great detail. Thank you
Thanks for sharing. Very illustrative 😀
Thanks Ulrik, Nice to hear from you again!
Looks great!! As I don’t have a table saw or anything I like watching these videos. Have you ever considered the direction of flow for the air inlet? Or adding another small inlet on the side to help the dust rotate from the bottom up into the hose? Just an idea!
Yes, but i do not want to damage my table saw. So that makes some try and error attempts limited
Excellent! Thank you for such a wonderful idea- liked and subscribed!
Super job! Heel erg bedankt voor je hulp. Cheers!
Brilliant, Genius!!!! Thank you :)
Hello Dennis, did you ever check, if your "box" in which the saw is turning is actually so well sealed/air tight, that without your extra air-inlets on top, the airflow in the box is actually insufficient ?
Otherwise it could be that the air-circulation under the table influences the airflow of the overhead extractor (and the other way around.), like 2 dust extractors with inlet hoses connected.
I made 2 extra inlets in the zero clearance insert and have the impression, that things didn't improve for me if I use both extractors.
If I only use the extractor that clears the box, things did improve probably a bit with your additional inlets.
I did a lot of thinking about this and came up with the following:
I checked my cabinet-box, and found, that there are a few openings in my table and the surface size of these openings seem about to correspond with the surface size of the extractor hose.
If you have too many openings (as I now may have) extraction-speed (and strength) are going down quite a bit, so perhaps it is a good suggestion to first check this.
what say you ?
Best regards, Karel
Hi Karel,
Your cabinet should not be, and probably will not be air tight. It has to cool the motor, but It needs air flow. But of course, you have to check if something is helpful. When I use my overhead dust extractor, I do not find any problem with dust. You understand your point and it was also my thinking. But most of the time, the wood is covering those holes in the inlet, so then the overhead dust extractor gets extra power.
So, no extra dissedvantage in that case. Most benefit I get when I want to clean up edges, and cut away small amounts of wood at the sides. And when you can not use your overhead blade guard, than it gives a lot of benefits. SO, in my case I an not find any disadvantage.

The design is very Van Halen!!
i'd be worried about the diagonal slots potentially catching on the edge of the wood and pushing it sideways or getting chips caught in them that could lift and tilt the wood.
Theoretically, this can happen. Without the slots, it works perfectly.
Very awesome
I'd really like to know what is that nail punch you use?
Extremely interesting video. I'll be making this for sure. Can you tell me what type of set up you have for your drill press. That hold down looks so effective. I don't know how many times I needed a 3rd arm to best drill a hole. TY
Hi, that clamp comes with this Bosh drill press. It is indeed a nice system. I do not have the bosh anymore so I implemented a rail in my drill platform where I can slide a clamp in. Works perfect too.
Your videos are amazing. Keep it up!
Thanks Cliff. Appreciated.
Great video, well explained.
Beautifully done. I also like your attention to detail and design. Your shop is amazing. Question, I am still not sure I understand why only the left side needs slots. I would imagine both sides of the blade would get sawdust? I know you found that out from your test I must have missed exactly why.
I have a question, so what about when you are using the miter gauge vs the fence? You could very well be using the left miter slot so the waste drops the right of blade - wouldn't then you need holes on the right?
the slots have two functions. To clean the cabinet (if you have a cabinet saw) and better dust extraction.
For cleaning the cabinet it usual creates more air volume and because this is normal a bit limited it will clean the inside of your cabinet better. It does this before and after the cut. For this, it does not matter where the holes are.
Second is better dust extraction during the cut. When you put holes at the right (when the fence is at the right) the holes are covered with the timber you are cutting. So, you need it at the other side of the blade. It is most effective for cleaning up edges when the holes are open during cutting.
Yes, you are right. You could make them on both sides for this purpose.
@@HookedonWood haha and I just got done immediately filling in the holes I had on the right after watching the video before I thought of that I think I will leave as your design and see how it goes. Another thought is obviously if you use a sled then nothing works... Unless! You also put similar slots in the sled? What do you think about that application? Or maybe instead put an overhead suction over the sled. I know I am ovetthinking but sort of fun! (esp during covid)
Hi Worskin, Your thinking is not that different from mine. If you watch Episode 14 you see at the beginning that I made a finger joint jig. You see I made a slot in this for better dust extraction. I think it is a perfect solution because especially with a sled, the dust blows right in your face and when you make a slot in it, you reduce this by 80%. At least that was what happened with my finger joint jig. I would recommend making it longer than I have done.
