Great video, thank you! I just ordered the same table saw and now I'm gonna have to order some blades and washers too :)

I had a fiend doing this 30 years ago on a radial arm saw, with even more blades without carbide tips. As long as the teeth are staggered like you did with the carbide tips, it worked great. A cheap alternative to an expensive dado blade set that is a unitask wall hanger for the average home shop

Очень давно про это думал. А спросить не у кого. Спс за идею!

Just had this saw delivered and great to know i can stack blades! Great video thanks!

I tried to cut dados with a single blade and it took forever. This is a great technique. Thanks!

Very good idea sir well done ,it seams safe and the saw can handle it

Hi, I have the same model but I never knew can use 3 blades for dados cut.excellent

This is immense, thanks! I’m wanting to do a lot of box joints but haven’t got a proper setup for my router yet, so was looking into this, and you’ve answered all my questions.

Genius! I’ve got the same saw. I’ll be giving this a go. Cheers mate 👍

Looks very interesting. I have the same model of saw but haven't really finished setting up my workshop so will have to remember this trick. I have subscribed though so will be looking at any other ideas you have shared. Thank you

WOW, THIS IS TOTALLY AWESOME. I LOVE DEWALT TOOLS. And I would love to have one of these. But I have to stick with my little smaller tools. But at least now I know how to do this.

Turning a router table into a joiner is well worth watching on the WORKSHOP TOUR

Thanks, just what I was looking for. I was thinking to use smaller blades as you will almost never need a full depth cut. (they will be cheaper also!)

Hi there I liked n subscribed!!! So I have DEWALT 78450 type 4. Yes the male end is a like short n can only go on cutter in between. That works. When I tried a wider stack this issue was more of a plastic piece limiting the width. Across From where the guard tightened is rything blade. I was able to take the case off n all it is is a plastic piece Since DEWALT already says no, I was gonna cut that limiter off. Wish I had a pic to show so you could understand what I’m trying to convey. Yes I understand now the other aspect of diameter of hole issue. Brilliant solution.

Why did you sandwich a thinner blade in the middle (2.1mm Kerf), why not the same thickness as the other two (3mm kerf)? Is it purely just to have a little more thread space on the arbor for the nut + washer to hold on to?

Thanks for the dado tip. Just wondering, where did you get the cool looking cross cut fence?

Hi! What brand is your miter gauge?! Do you recommend for the DWE7491RS? Thanks great video

..hello there, great idea for DIY dado. I bought the exact thin kerf blade for the middle blade. It came with 2mm washers even though the blade body is 1.2mm, my question is would it be safe to use the 2mm thick washer for the thinner blade, the middle one. I installed the 3 blades and it seems solid enough although I'm wary to use it, maybe oll wait for the thin washer to arrive in the post! thanks again

Interesting idea but ill stick to my router table. The combined weight of the blades will have an effect on the saw motor and brake over time. Sucks we can't have this option as standard in the UK.

These blade reducing bushes are available at AXMINSTER .CO.UK and are on page 17 of their 2020 catalogue

Visit my channel and check out the play lists (De Walt 745) and (woodwork) for examples of me cutting dados

Hi Sion. Congratulations on an excellent accurate and professional video. One thing is where do I get these blades I cannot find the precise blades on Amazon and certainly not in B&Q. Are the two outside ones the standard ones which come with the machine?

I have noticed that the blade drops a bit (the hight adjusment handle moves) when cutting dados/rabbets on my own DW745. Is there a way to prevent that, other than physically blocking the handle?

Great video! Do you have the link or site name where I could get these washers? I have the Dewalt DCS7485N-XJ 8” inch would the same concept on my saw table?

Wow i didnt this it was possible to allow for dado blades on this model. I've had mine for a few years but im not very confident with it. Really should build some jigs

Is it true that dado stacks are not legal in the UK. I’ve heard they are not sold there for health and safety concerns

hello sir were can i get them washers

do you have a website to purchase these

hi Sion, is this working correcly? i heard dewalt saying they dont approve this because the blades together are to heavy for the motor brake. Instead i use dado blades from the USA (the arbor of the blades is 16 mm, so fits without washer)

thks

You can also buy a new arbor and put a13/16 dado on this saw

Where can you get the special washers?

Can’t get blade off. Tried pushing the spanner’s together as per instructions unscrews in the book but you demonstrate pushing spanner’s together tightens

Any ideas if this will work on the 7485 model of the DeWalt jobsite saw? It's a 8 1/2 diameter blade, so slightly different. Awesome video btw, very concise and accurate and takes the guesswork out of performing such an uncertain and potentially dangerous modification.

NOOICE!

Whats the max anyone has achieved from dadoing this table saw?

That's great but why not use a router and router table? surely its more convenient?

Watch my NEW video ………ZERO CLEARANCE INSERT REUSABLE …………. It’s a reusable throat plate for the DW745 …………..It’s completely unique

Seems to me there could be a market

Isnt this dangerous though? Arent the blades free to spin on themselves? I wouldnt want to imagine the damage when those carbide teeth collide at 3800 rpm and the bits fly into your face

There is a safety issue with your table saw. When the saw is started, the inertia in the saw blade causes it to have an anti clockwise force and, thus, creates an undoing force on your locking nut. To overcome this my sheppach saw has a locking washer which counteracts the anti clockwise force - the locking mechanism is a flat spot on the spindle which is mirrored by a flat spot on the washer. The reason I am aware of this is because I bought a dado set many years ago and it would only go on my machine without the locking washer. It was only by fantastic luck that the flying dado did not hit me! Dado set ups are not allowed in the EU for safety reasons and that is why all our table saws have short spindles..

The downfall with this is your dado is going to have ridges and not be flat. That ATB catbide design prevents it from cutting a flat bottom. The best way to get dadoes on this saw is with a box joint set. But, that can be as pricey as a dado stack. There are also blades with a 6.4mm (¼") kerf... but still pricey. Before i got a ⅜ box joint set, I used a full kerf, FTG (flat top grind) from Freud. Its their heavy duty glue rip blade and its super beefy. Its 3.2mm (⅛") and it also is great at jointing , and rabbets on the table saw.
