A new zero clearance insert you should see!

This video is about the H.O.W. Zero clearance insert. It is a zero clearance insert but improves dust extraction.
This is a remake of a video a made 1 year ago, but I want to make it again because in this video I also included how I made it and I share the dimensions.
I also put in some shots so you get a better understanding of the dust extraction inside your cabinet saw.
Nice items I used in this video are:
T-Ruler from "NEW"
www.banggood.com/custlink/DKv...
Drill bit kit
www.banggood.com/custlink/33v...
Tap bit kit.
www.banggood.com/custlink/KGD...
Black MDF
I get a lot of questions about the black MDF. In the Netherlands this is fairly easy to obtain in the hardware stores. Here they call it fully colored MDF.
Valchromat is also a fully colored MDF that is available everywhere. I think this is also very suitable, but it is much more expensive. However, this is a bit more robust, stiff and denser than the MDF I use.
What I use is not Valchormat, but it looks a lot like that. What I use is cheaper and costs around 80 euros here in the Netherlands for a 240 x 120 cm sheet.
I see several manufacturers worldwide who make fully colored mdf. The problem is that there is no brand name here in NL for this MDF. So I find it difficult to indicate which MDF is comparable with this worldwide.
I believe in the USA this could be the same: www.forescolorusa.com
These are the products I use in these video, and where I bought them.

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.

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.

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.

@HookedonWood 4 жыл бұрын

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.

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 <a href="#" class="seekto" data-time="660">11:00</a> 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.

@HookedonWood 3 жыл бұрын

@stephendixon8575 3 жыл бұрын

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 ...

@HookedonWood 3 жыл бұрын

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.

@Tensquaremetreworkshop Жыл бұрын

There are some issues with your analysis- You are adding air inlets through the insert plate to the left of the blade, to increase overall airflow. But, unless you are cutting very slim strips, these are soon covered with the material, so cannot work. Internally, the dust shroud is rarely attached to the table, so there is already a gap that lets air into the extraction path. There may well be an optimum gap for this... If the cabinet is sealed, what is needed is a duct from outside to the side of the blade, sized to give optimum airflow. The material that the blade cuts is trapped in the gullet as it traverses the material- and then by the sides of the insert (if it is zero clearance). It is desirable to clear it then, before it rotates and ejects upwards.(The rake tends to retain the dust.) Ideally, there would be a sideways jet of air, pushing the dust out of the gullet on the underside of the table. A good design would have an internal shroud that directed air from the left of the blade, through the gullets to the right and then away to the duct. All the saws that I have seen have fairly crude dust shrouds. It does not seem high on the manufacturers priorities... Clearing the dust in a cabinet saw- a well designed dust shroud will taper downwards until it forms the outlet duct, so dust will fall by gravity to the duct, and there will be nowhere it can collect. The dust that appears into the workshop is mainly that which has not been cleared the gullets under the table and escapes above- one solution is to fit a brush rimmed extractor on the top, of the sort used by CNC machines. If there is no route out for the dust, you will not have any dust.

@HookedonWood Жыл бұрын

Hi Mike thanks for your analysis. I do not disagree with everything you said, and it fits perfectly in my analysis. But I do not talk about what could be. I talk about what I have. And I do not have a dust shroud, so my dust falls in the cabinet. My dust extraction system could not clean this with the holes in the cabinet. So, by creating this extra gab in the zero clearance, this improved. When you place a traditional zero clearance, you just make the airflow worse. I agree with you about the thin strips. But I do use it more than I thought. When you cover the holes, it acts just like every zero-clearance insert. So, my zero adds only something positive. When you have done your cut, the extra holes clean the inside of the cabinet. All the other improvements you subscribe to are for the manufacturers. And I agree this is a field that can be improved. However, they give more priority to this nowadays. Thanks for your comments

@Tensquaremetreworkshop Жыл бұрын

@@HookedonWood Your slots will certainly help with removing internal dust whilst not covered- and that is probably the majority of the time. As you demonstrate, it prevents build-up of dust within the cabinet. My concern is more with the dust that escapes entry into the cabinet (or, more accurately, is ejected upwards by the blade after traveling through the inside). Yes, this is a different problem- but a more serious one (the dust inside will eventually rise to the point of being extracted- it will form the shape that a shroud would have given; it is doing no harm in there...) as it is now airborne. I am more used to saws that are not a sealed cabinet- probably the majority of them. These 'leak like sieves' and would be unlikely to benefit from such slots. Sealed ones will, and for those this will be useful. However, an insert that had an extension to take the slots down to the periphery of the blade, directing the air to the side of the gullets, would achieve both aims. A 3D printing project?
