- In this video, I show you step by step, how to make a zero clearance throat plate for a Dewalt DW745 Table Saw. This is an easy upgrade that will result in cleaner cuts, especially when cutting plywood perpendicular to the wood grain. It will also improve the safety, by not allowing thin cut strips to fall back into the blade throat.

You do have to spend some time setting the saw up... blade, fence, etc. But once done, the saw is great. Fairly compact which is Nice ruclips.net/user/postUgkxXh-4_3-ZT1fFWP91ZV7iVqzElr0lEb-a I did get an Incra Miter Gauge which takes some setup as well. The stock miter gauge can be adjusted in the miter slot with a little painter's tape... this tightens up the side to side play a lot.
I just discovered today that the throat plate had set screws. I was about to buy a new one! Great video! Meticulously explained without wasting time.
Thanks for the tutorial. Great video...loved the clear and concise instructions!
This is one of the most meticulous video tutorials I have seen. Well done and thanks for sharing.
Best one on making a zero-clearance throat plate. Thank you! I will be making one soon!
I can't beleive this video was made sooo long ago and it's STILL one of the most helpful videos online. Great job, Thank you Sir!
Glad it was helpful!
It is a great saw! Well made and fair price!
I have looked for a video like this!! I have procrastinated so long to make a zero clearance insert bc I couldnt figure out how to remove riving knife. All other zero clearance how to videos shows the riving knife already removed. Your video was so well demonstrated that I went & finally made my zero clearance insert! 😄 I cannot thank you enough for putting this video out! My project is no longer on hold because of you!!
Thank you for your kind words. I'm glad this video helped. Thanks for watching and supporting this channel :)
Girl you need to read the manual carefully to learn how to remove the riving knife and every safety information. Table saw is dangrous, please be safe and patient with it. If you lose your manual, you can find it by google and print, keep it with you and read often.
Cut the slot after cutting your radius and sanding.
Jeff, made this yesterday in under 15 mins, thanks so much for your easy make video.
The only thing i did different was I used Hot glue on the tabs where the set screws would go
I applied the glue and then set the insert in while it was still soft and then used two metal straight edges
to set it flush and level with my table
Thanks again
That's a great idea! Thanks for sharing your advice and I'm glad the video helped.
Great instructional video, i hope my dewalt 7491rs has the same measurements.
You deserve more subscribers. I’ve seen so many ridiculously over engineered ZCI videos. Using template routers and all this jazz. Always wondered if I was ghetto for just using a jigsaw as I was very new to woodworking and was learning about tearout at the time. I didn’t have a ton of equipment or skill but still wanted a ZCI and didn’t want to buy one. This method is great and works. I’ve been using mine for several years. Made a couple actually for thin kerf and full kerf blades.
That was a great comment. If you want to do woodworking, start with what you have. As you go along if you feel other tools can make your work faster or easier, buy those tools. But, remember (Quote, I do not know the source), if you think you need the most advanced tools to do a job, you're right. If you think you do not need the most advanced tools to do a job, you're right.
Excellent video, thank you
Awesome work 👍
Informative and well presented,my man!
Glad you liked it!
Great video and commentary thanks ❤❤
Awesome tool
Excellent video. Thank you,.
Good job and a super handy piece! Thanks for the clear and simple video with no music, no advertising or accessory nonsense and so forth.
p.s. I do like the sander you showed. Now I needs me one. If only I can convince "she who must be convinced" that another tool is in order... :-)
Glad you enjoyed it!
Nice one!
Thanks for this! Great explanation!
Glad you enjoyed it!
Thank you. Well done. It is also possible to set the width cut by using the OEM throat plate between the blade and the fence.
Thanks for the suggestion. I appreciate hearing from fellow woodworkers.
Very good! Thanks
Thanks so much
Thanks for your response. Quick question does your fence over lap and hold the material as a base for cutting wider material
Hello, great video, I'm curious, with the blade guard on, is it possible to lower the blade nearly flush with the cutting surface, or does it need to be removed? Thanks a lot.
Good job
Thank you
Excelente
nicely done
Thanks.
If you have a planer and router; try using MDF with hardboard glued to it. Then use router to cut shape using original as pattern. Then plane the MDF side to thickness without using screws.The advantage over wood is I have never had one wrap. Some use Thin formica for surface If you need to one or more areas can be recessed as needed on drill press using a stone bit.
Great. But have you provided some sort of locking mechanism as what the original insert has?
Thanks for commenting. I didn't add any system to lock the insert onto the table. I simply make the insert have a tight fit, and rely on friction to keep it in place.
Cheers
In my first use of that table saw I had many pieces get stuck in there.
Hi Jeff, At last I own same table saw. Now i need you advice router inserts. Will a plywood of 8mm thickness have the same efficiency or strength of a metal router insert.
I'll try to answer your question. First off, congrats on the purchase of your new saw. Now, when it comes to router inserts, there needs to be enough strength to support the weight of the router, plus the downward forces applied when using the router. Also, the insert must not deflect when is use. Based on these factors, a metal insert is the ideal material. However, you can may be able to try the 8 mm ply. If it doesn't work then try a thicker ply. Hope this helps.
Thanks for the video!
Hey mate. Nice video. Noticed you’ve upgraded the saw blade: how did you go about getting the Diablo blade with the 30mm bore to suit the 16mm arbour of the DW745?
Thanks for watching. In this video, I'm using the Freud LU87R010. Hope that helps answer your question.
Hi did you reconstruct your reviving knife, because your looks a bit different. Please make how redesign reviving knife if possible
This model had a riving knife installed from the manufacturer which I didn't modify or change. If your model is the DW745, this method should work. Thanks for the question.
Or get a pattern following router bit?and make lots of them in short time, there’s a lot of videos on RUclips that explains this process, very well made video with an alternative method of making inserts.
Yes. Flush cut routers are one of the most useful tools in the shop - especially if you have a table router. With the original metal plate to use as a pattern you'd get a perfect copy in no time flat. I would do the same as you and save the first plate as a master, as you are bound to need more over the years. I was also wondering why he didn't mark the holes through from the original plate?
Hi one question does the size of throat plate various or they are same for DW 745
The Throat Plate Assembly for the DW745 Type 2 & 3 use the same part (P/N: A26208), however the DW745 Type 1 uses a different throat plate (P/N: 5140033-52). I'm not sure if both parts are all the same size. Hope that answers your question.
i have this table saw dw745.. however, how did you solve the noise problem of universal motor?.. i have an idea to change this universal motor to brushless dc motor.. have u ever though that before?
Great question. It appears Dewalt has a new cordless table saw (DCS7485T1) that utilizes a DC Brushless motor. Based on the specs, it may not be as powerful as the DW745. However, as with most things, I'm sure it will be a very competitive table in years to come. Thanks for watching and taking the time to comment.
Been thinking about this for apparently too long. I've got a Lowe's contractor type saw, Kobalt I believe is the name on it, and finally decided to bite the bullet and make the zero clearance throat plate. I've seen a lot of videos on it. Yours is one of the better ones. So I pulled the plate off yesterday and found it to be almost a quarter inch metal plate. No way to build a nice wooden plate that I can see. Can't find any wood that isn't bent or warped in that small a thickness. Got any ideas for man made materials we can make these out of?
Great question. I think you may try using 1/4 inch MDF. It's easy to cut and shape, and is less likely to warp when compared to plywood.
I made one for a similar saw using 1/4" ply to attach where the insert screws to the table but added a smaller insert of 1/2" ply inside the opening for the blade to strengthen/flatten the insert. Hope that makes sense.
What is the name of the piece that you have clamped to the rip fence ?
That's a feather board
Hello, i have a DW749IRS table saw and after installing the anti-kickback assembly on the blade guard attachment, for some reason the spikes only on the left side of the plate are getting caught and stuck on the throat plate when i raise and lower the blade. I have adjusted the throat plate number times and have checked to make sure the throat plate is not bent. There is a groove on this particular throat plate made by Dewalt in which the spikes from the anti-kickback assembly is getting caught on. Please help i cannot find a solution anywhere and have found no one else who has had this issue on the entire internet. P.S it IS installed correctly, and i called a Dewalt service station and they just said to bring it in, but i wanna fix it myself b/c the drive is just way to far. HELP from ANYONE is welcome. Thanks
How do the throat plate screws alter the height of the throat plate if the holes aren’t threaded?
I think the holes he drilled are smaller than the set screws, so they thread as he screws them in. If they lose threading over time then just create a new plate.
Can you make one out of aluminum?
Hi Jeff,when u making the table saw insert you use the bell sander. Can we use the disc sander instead of bell sander if we don't have one
Sure, you can use a disc sander. I just used my belt sander because it was easy to use for that application.
I have seen in so many videos that the riving knife is removed... do you know why is that ? I´ve noticed on my DW745 that the riving knife is not aligned to the sheet, it´s probably 1 mm or 2 to the left. I thought that this was the reason to remove the knife with zero clearance inserts !! am I wrong ?
The knife should be parallel but slightly thicker. A true zero would need a fixed splitter added.
Totally backwards. I just made two zero clearance throat plates for my Delta unisaw. I removed the blade until I had the fit perfect. Once I put the blade back in I just set it with the front portion on the two front supports and carefully lowered it until the blade started contacting and continued until the insert was set in place. I shut off the saw, moved the fence to cover less than half so it was clear of the blade. Started the blade and raised it until it was at full height. I shut it down, flipped the plate over and fed it directly into blade with it on so it would cut a clean slot just long enough so splitter slot and blade slots are not joined as my saw doesn’t have a Riving knife or splitter, I modified one plate for a splitter and one without.
Hi Jeff,I have a question. I've recently bought dewalt 745 table saw. Will it be ok to build a stand out off 12mm MDF
I'm sure making a stand from MDF would be fine. Since I like to make my saw mobile, I decided to purchase the Dewalt mobile stand, amzn.to/2BA8sOi , which works well with the DW745 Table saw.
Thanks for taking the time to make this video! I’m getting into woodworking and I just bought a dewalt dwe7480 table saw. I want to do this on my saw. I noticed the throat plate has screws on the edges but there’s no threads on the metal tabs that you marked with the paste wax. Why is that?
Charlie Petway the tabs aren’t meant to secure the plate to the table, but to level the plate up and down in relation to the work surface.
Tim B thanks I figured that out after looking closer at it and watching all of your video.
How does it lock down?
The only thing holding the insert down is the weight of the insert & the tightness of the fit. Initially I was concerned about it staying in place, but after hundreds of cuts, I haven't experienced any issues with it coming loose while in use. Thanks for the question.
Plz show cutting the slot next time thanks
What about when you cut at an angle? Will this still be a zero clearance when cutting at a 45
No, only zero for 90° cut. The process is the same for 45°. When he cuts at 90° in the video, cut at 45° instead. Don't cut your push stick!
I am a bit concerned about safety, as there is nothing securing the throat plate to the table other than gravity...
Mine is the older model with the simpler riving knife (without the notch for the anti-kickback) and a Philips screw for locking the plate to the table.
Henrik Paulsen I wondered the same thing. I’d fee better at least including the small flanges that sit just under the surface on the back side.
@@taterberryman When I made mine I drilled a couple of small holes (to prevent spitting) on the rear of the new throat plate where the tabs are located on the metal plate and installed a couple of small nails. I used 1 1/4" nails with a drop of CA glue and bent them for fit to prevent uplift. I also bought a bag of 10-32 x 1" nylon set screws, (no head just a screw driver slot on top and cut them to 1/2" in length, then drilled 4 #29 holes in the plate, put a 10-32 tap in my drill and tapped them out, no countersinking I made several plates from 1/2" Baltic Birch plywood and a template out of 1/4" MDF. Safety First
DAP460 That sounds like a solid plan. I’ve seen one other use the nail approach, and as the Dewalt holding tabs seem a little tricky to replicate (at least with my tools and skill set, anyway) I’ll probably go that route as well. Thanks for the input!
What holds the plate down so it won’t lift?
+F Vids The only thing holding the insert down is the weight of the insert. Initially I was concerned about it staying in place, but after hundreds of cuts, I haven't experienced any issues with it coming loose while in use. Thanks for the question, I should have addressed that in the video.
Woodworking Explained thanks
In European version is very difficult and different. ..
Hi,I liked this video making zero insert, how many teeth does your table saw blade have
The blade has 24 teeth. If you want more info on the blade I used for the video, I've left a link in the description. Thanks for watching.
need better lighting (camera guy here), but I reproduces this ... nice job.
Why not just trace around the original????
Please send me yours 😁
Seven forty faaa
Still unclear on what the purpose of zero clearance is
Essentially without one bits of wood can fall in that hole and either jam up the blade or the blade can throw pieces back at you. Also as I recall it decreases the chance of kickback a bit too.
The most desirable benefit is that zero clearance throat plates support your workpiece immediately to the left and right of the saw blade as it’s passing through the wood, which keeps the wood from tearing as the blade exits. The resulting cut is clean and not “fuzzy”
@@andypitz1 excellent answer thank you
So with that in mind, a cross cut sled will not need a zero clearance because it is a zero clearance.. agree ?
Doosha Khaboosha thank you, and yes, the final step in building a crosscut sled is making a kerf cut into the sled, which creates a zero clearance effect
I did that a lot easier! Traced the original, cut it, put plate in slot, start table saw, raise disk,.......VOILÀ!
How did you account for the riving knife?
please get a microphone! :)
Excellent video, thank you
