How to Make a Double Mortise & Tenon Joint

[@marcmoquin3735]

Mark is a smooth operator. Clear instructions and simply a down to earth cool guy. Thanks for your work.

Love the humour dude, always a pleasure. Been in the game 28 years now and still enjoy the videos in my spare time, of which there never seems to be quite enough. Not too much rest for us joiners it seems. Everyone wants their piece of work.

[@jamesseagraves5630]

I have never done mortise & tenon joints. I think I can do them now after watching your process. Thanks for the step by step on how you do them.

[@atwalmcn88]

It can save you a lot of money on woodwork project if you have the in depth woodwork system. I have written all of my experience & expensive mistakes I've made in my very first days on wood working. You should discover more about it: *TopFineWoodworking .Com* >>>>>

[@markbolden4540]

2015 video and still great! Thanks for the class!!

[@RobertEchten]

Very nice. I did catch the version you did in the live show, but you are right: This one was much clearer. Thanks for (re-)doing this.

[@woodwhisperer]

Yeah there's only so much you can do in the live format.

[@ralphzamoyski2807]

I just got Leigh FMT pro M&T jig and seriously nothing compares to the speed and precision of that machine. The Video is great, always nice to know other more conventional methods of doing M&T

[@nolanwoodworksartcompany6612]

So in the process of making an above average size dining room table and I kept thinking to myself what I could do to make it stronger without adding too much wood, I gotta say this is it, what a great idea, going to definitely use this method. Love your videos, watching you on my Roku right now as we speak, your dropping the first router hole, lol. Your wife is such a great help, my wife loves helping me in the shop, gotta say she's learning quite a bit, few more years and I will have the kids experts as well. Beautiful shop btw, I will have to send you some pics of mine, always open for advice, especially from you.

[@AndrewMiguelez]

You are a fantastic host and your friendly, funny personality comes flying out of the screen. Thanks for all you do and for doing it with such warmth.

[@woodwhisperer]

Thanks Andrew. I really appreciate that!

[@kwhp1507]

I don't want to be a woodworking journeyman or master. No. I want to be a Woodworking Ninja! I love it when you say that! Love your videos. You always make them very thorough. Thank you

[@GrahamOrm]

I enjoyed that! Nicely done, especially as it fitted first time!

[@antonioperito6607]

I think it's fair to say that you have become the new Norm Abrams. Thank you for these great videos.

[@johngulick5629]

Great video, we have a few 2 1/4" doors to make soon. We will be using a mortiser in place of the router. Can't wait to get in the shop to crank out a few samples tomorrow. Thanks Mr. Whisperer

[@JonPetersArtHome]

Nothing like a nice snug Mortise and Tenon joint, great video Marc.

[@MattLaneWoodshop]

I plan on trying this joint in the near future!

[@Samsgarden]

That's what my boyfriend said to me tonight

[@derekcohen1000]

Hi Marc It needs to be emphasised that, when routing a double mortice, the marking out and the routing, can only be done as you demonstrate IF the stretcher is parallel. In traditional joinery, marking is only done from the reference side, as might routing. It is convenient to flip around the stretcher to use the settings of the router on the other side, but this is dependent on the sides being parallel. You would not do this if the stretcher was prepared with a handplane.

[@steviesgarageworkshop2392]

Thanks Marc another great video. This is one method I will add to my projects to try list. Will come in very handy when needed.

[@loloent]

Hi, don't have much but I would love to spend a week at ur shop pay for ur time & learn from u somehow, like I did when I was young helping my dad in his shed who now has alstimer & dementia

[@williamhodges2786]

Great video! Very easy to follow along to, will have to give it a shot!

[@DroweHP]

Think I've seen this video about 10 times and still following your advice. Thanks. ;-)

[@RC-oi1gg]

Informative and confidence inspiring as with your other videos. Can you advise the best joint for a sash window when jointing the bottom rail and stile please. Thank you.

[@anthonyamatruda5937]

Great video Mark! Straight forward and to the point. I can't wait to try this out

[@ВсеволодКузнецов-н7д]

Да, нам о таком инструменте только мечтать, в СССР вообще было туго с ручными инструментами и средствами малой механизации. Приятная мастерская. В России растёт много древесины, а мебель из опилок делают и импортной пленки😂😁🤗

[@thomascollins72]

Great video. I gotta find time to get in my shop today. Thank you.

[@philippboetcher9959]

I had to do that joint by hand last week in college, it was harrrrrrrd!!!!!

[@exotoguy]

Great video, VERY Well explained! Really appreciate these tutorials!

[@ZackChapple]

This videos are so well produced and educational. Thank you!

[@SenorHeisaCoolguy]

Hi Marc - not sure if you still follow this - two questions: how "snug" should tenons be in the mortise? And two, with the recent news about end grain would you make the end grain portion of the mortise "snugger"/square for the sake of an additional glue surface in the mortise?

[@renoholland7090]

Another great video and I just have to try this technique.

[@greyshades9114]

That is just so cool! Thx for explaining and your time. I really like the way you teach, thanks from Holland.

[@johnmackenzie2311]

Good video, good teacher. I always wish you went into more detail for us newbies. What size stock are you using? Dimensions of the mortise and tenon? It helps to have a perfectly square piece of stock like the one shown in your video. 4x4 cedar posts are never square and have to be jointed and planed. I've learned the hard way that mortise and tenons on a 4x4 cedar post can be frustrating because they aren't perfectly square and each piece has different dimensions. It really helps to have a jointer and planer and of course a Festool router, spiral router bit, and a Powermatic jig!

[@petrlukpv4023]

good one. please show how to do half blind double m&t joint with moldings and spunts

[@solath]

1 suggested tip - when you cut the mortise for setup, instead of removing the whole center section just trim about 1/16" off the center. This will still allow the single tenon to slip into the mouth to check for size but it should also be usable to mark the center layout without having to eyeball if you got the edges lined up correctly. You could even over-cut the center to make it easier to mark.

[@danteVEC725]

VERY CLEAR DEMONSTRATION......

[@معراجرینا-ر7ل]

Beautiful absolutely beautiful What kind of router you use for this presentation

[@cmassey1999]

Well done, Mark.

[@maidayjeen6919]

GREAT video and you are AWESOME. Many thanks.

[@AwesomeWoodThings]

Hmm... "No one will ever see it." The good thing is... I'll know it's there! Great technique!

[@gangadharankumar5980]

Thanks for easy joint work and your explain very well -----Thank You---

[@Finewoodworkingofsc]

Great video, Marc. You're right, this makes for a very strong joint due to the increased surface area for glue contact.

[@kevinhancock4064]

Great video I've not got a table saw only a circular and sliding mitre I guess still can be done with what I have but that table saw makes it easier

[@gilcevallos5172]

would just like to know what type of small combo square is being used... love your videos and have learned a lot.

[@larchejacquesclarel9451]

clean and beautiful joint with the strength. great job as usual. Always enriching to watch your videos. by the way what is the main purposes of a double tenon compared to a single one apart from the strength???

[@TheSageDad]

Any concerns with the half moon gap created by the router's round bit? You could probably make some plugs by splitting a dowel in half... it just seems to me that there would be some 'wobble' room without it... thoughts?

[@woodwhisperer]

Those are something you deal with any time you cut a mortise with a router so it's a detail I left out of the video, but the write-up on my website addresses it: www.thewoodwhisperer.com/videos/double-mortise-tenon-joints/

[@demmery1160]

I was thinking he would cut the tenon over size and round over the edge so it was a tight fit, thats what i have always been told to do when using a router.

[@TheLukkystrike]

This was fantastic and I thank you for your time!

[@ArronVTiS]

Love the honesty at the end Marc, lovely piece of work, that no one will see lol Great Vid 👍

[@ianlee9067]

Good professional job. Need to ensure that the material is perfectly square or else you will get twisted tenons

[@CDLeon1224]

very cool video ...of course he has all the cool tools to

[@sojace]

When routing out the mortices could use two quick clamps as stops for the router, this ensures not going over the lines at the end of the mortices, quick and easy to use

[@IntimateGamer]

Awesome vid. Thanks brah! Im going to try this in my home shop.

[@richardwalker8165]

what a legend, thanks dude another awesome method

[@AmerijamAcres]

Curious if you’ve ever considered the panto-router? I’d love to see someone build one using the plans to see if it’s as good as it looks.

[@Bloodsweatsawdust]

I'm a big fan of draw-boring mortise and tenon's but this is very nice. I'll have to add it to my arsenal. I think they would look really nice as through tenons.

[@M4ngstergangster]

Really nice video!!! Looks awesome.

[@xl000]

4:01 I have seen another KZbinr doing the same thing (kern lines) without a sled. He claimed to have "15 years of experience" but it looked dangerous. His thumb was close to the blade. I can provide a link if necessary. Basically he was pushing against the fence to ensure the wood was moving parallel to the blade.

[@JorgeAraujo]

Hell now... If I am doing double M&T you better believe its gonna be a through tenon so they show... LOL! Might look cool to go through the mortise stock and then get a pin on the outside or a wedge... Great video... sure is cool to see the difference from the recording on the live show to how you edit it to make it easier to understand and clearer. Great work.

[@larchejacquesclarel9451]

through tenon are likely to warp with time. is this true?

[@tatilbury]

Excellent well explained video

[@Nosmo321]

Loved the video as usual. You have a great ability to explain and teach, my hats off to you. That being said, I would prefer to be a wood Viking than Ninja, do you have a video for that goal? TY! lol

[@jamescampbell8380]

Thanks for all of the quality content Spag! Could you draw bore the double mortis and tenon? Or is this asking for trouble?

[@danteVEC725]

nice job sir......greetings from Philippines.........

[@PLAYERMIKEY]

I wish I had money and time to make things like this.

[@bigfatbill5187]

I love your mitre gauge on your table saw.

[@goddale2002]

Question for you. The rule of thumb says The thickness of the tenon should be 1/3 of the board. Another rule says 1/2 so I went with half. On a 2 x 6 board, that means the mortise will be 3 3/4 deep. What router and spiral bit combo will accomplish that task.

[@mrconcept]

I know nothing about carpentry/joinery but can i ask - it must be time consuming to make cuts like this, is it worth the time spent doing them financially? I mean from a business perspective is there a demand to do these cuts or is this more of a perfection/best it can be type of thing ?

[@aumdy]

I was originally going to join a corner piece using dowels and a self-centering dowel jig till I saw this video. I have a square corner piece that I want to join to the two beams of a 1.5 inch thick frame. Can I use this type of join instead?

[@WoodworkingCraftsman]

amazing

[@dpmakestuff]

I love this guy.

[@woodwhisperer]

I love you to sir.

why don't you marry him Im sorry couldn't help myself. forgive me

[@mountainviews5025]

All of his work or ideas that you see are a copy go look around the internet y'all will see this guy's name means nothing this 860 a month is all that he makes nobody like what he makes I've asked everyone to check it out we don't know how he got the subscribers THUMBS down y'all

[@JeremyUrbanWoodworker]

I wanna be a woodworking ninja!

[@amazai84]

me too

[@mrchromaticable]

Drum kit in the shop. Awesome

[@victorbrown9850]

great work and training !

[@PhG1961]

Awesome, good job and well explained !

[@GadgetsandbikesGB]

Very informative and damn useful!

[@emanalbar]

very nice.... thank you for the video.

[@AndreaArzensek]

We need Matthias Wandel's experiment to determine if this is stronger than single mortise joint. Great video, great instructions. PS I've never received your T-Shirt :(

[@TheDavidpai67]

He did a rather thorough examination of different joints. I was surprised by the finger joint results

[@DiHandley]

Thank you. A very helpful video. Cheers.

[@muderabbas2517]

it's vary good work I see

[@GinoDelgado]

Good teacher.

[@koalafan1576]

You went over the line on the plunge, lol. Keep up the good work though. You do awesome work and videos. Do you cut why and use a chosen to clean out your mortis so they are squad and tight on all sides or leave the ends round like you did in the video?

[@hassanal-mosawi6049]

Thanks for showing and sharing that

[@ivwoodworking1034]

Dude. I just love every one of your videos. Thanks! (You excitement over the initial perfect fit was contagious - haha)

[@aaronbecerra2958]

i like your video it`s easy how you do. But i don`t have the experice maybe i try some day see you parner`s im from Acapulco Mèxico

[@keithweagle]

Great video, but I have to ask, would this really be that much stronger than if you had just made the tenon without cutting the middle part out? I know you get a bit more glue surface, but there is also less wood at the base of the tenon. Having said that, I think this method would look great using through tenons.

[@woodwhisperer]

I honestly don't know if it's stronger. My gut tells me that in many cases it would be stronger. Substantially? Don't know.

[@barearsed]

Woodworking with The Wood Whisperer Test your gut. Assemble some test joints and break them. That's the only way you will ever know if you are right. Even if you are wrong you still learn something.

[@CiberWizZ]

Weraisedstupidkids That I would like to see!

[@TheOlsonOutfit]

I was also thinking this could make a cool through tenon.

[@ugoleftillgorite]

Sounds like a job for Matthias Wandel!

[@DynamicalJon]

I noticed here that you cut the tenon's a little short so that you didn't have to round them, do you think that because of the additional glue area that its okay to do that when using a double MT joint? Also, would this also be fine for a single (regular) MT joint?

[@dfolse1912]

So for a project I am about to start... is there a way to use Mortise & Tenon to join 2 boards into one (example combining 2 - 4ft 2x10's in to 1 - 8ft 2x10)

[@BraxFilm]

what is that bit you use on the router? We dont have those here in Norway, maybe i just have to use a normal wood drill?

[@edmacfarlane9483]

Could someone tell me the name of the type of router bit please? I have bougt myself a router and want to make some nicer joints. Thanks

[@danielstephens7626]

Ed Macfarlane look like a 3/8" upward spiral bit with 2 flutes. He's using a 1/2" shank to match his 1/2" collet but I'm sure there are 1/4" ones out there too.

[@Fredwitrave]

Nice work!

[@SeanKelly1]

hi there. how do you decide how wide (i.e., what fraction of the stock width) to make the joints? I'm used to thinking thirds for a single tennon, but is this wider than that? thanks!

[@mrgoodtime87]

Hey guys...question..are Festool tools worth the extra buck? I love the $600 Dewalt 12 inch double bevel sliding miter saw. Is the Festool miter saw really worth $850 more? Thanks.

[@shawndasharkk1138]

Great video. Im just starting. Woodworking so i guess. Im a baby ninja thanks Shawn

[@themrhelperguy]

Very nice work. Very nice

[@StephenPugh56]

Hi you might like to see how l cut a mortise and tenon joint by hand.

[@sammas8103]

Really good work here, you deserve thumbs up and anyone I can learn from I sub to. Thanks you for your tutorial. It's the almost midnight of 24th...I know what I want tomorrow. lol...hohoho Happy Holidays bro.

[@ABRAAOSERRALHERIANAGARAGEM]

Congratulations, great job.

[@nadjaholtkamp556]

Nice video.

[@pleasetakemynamenow]

Would you be able to make the long enough to be flush with the opposite side? That way the are not hidden...

[@pollelibre2649]

Nice… If you add a second edge guide to the Festool router it's easier to keep it steady on the edge of the wood.

[@TheKlickitat]

Excellent video and thoroughly enjoyed it, but do do question the benefit of the time to make a double vrs. a single mortise and extra time it takes to make the double against the strength advantages. It would be very interesting to see a torture test of the two joints to compare any advantages. Again a great video and the fact that it brings up more and deeper questions only proves that fact.

[@woodwhisperer]

Agreed. I would love to see someone go through the testing process with single, double, and even triple mortise and tenon joints.

[@GrahamOrm]

Woodworking with The Wood Whisperer Matthias Wandell did some tests on finger joints versus dovetails. I believe the finger joints won! He used a rig with a hydraulic bottle jack and a bathroom scale to measure how much pressure he was applying.

[@keithweagle]

***** Thats right, he did. The results also showed more glue surface does not make up for the loss of wood from making smaller finger joints. At some point, the wood that is left attaching the tenon becomes much weaker than the glue joint itself, which is why I wonder if the double is actually stronger. My gut tells me it is not, and that it will fail at the base of the tenon sooner than a single tenon would.

[@GrahamOrm]

Keith Weagle To be honest Keith the wack that it would need to break a single tenon that was well glued would be way beyond what most folk would call normal use. It's all hypothetical unless you're making a particularly fine joint that will take weight....my advice would be....don't.

[@keithweagle]

***** exactly, which is why I dont think the extra effort to make a double tenon is worth it.

[@ysrdan]

Thanks for sharing.

[@TheDrB0B]

I like this, but doesn't having that space leftover affect the joint strength? If you're gonna build a jig, wouldn't it be best to just build a pantorouter? It doesn't take more than a day if you work efficiently.

[@rafah4329]

Do you typically cut the tenon shorter then the mortise when routing a mortise and using a square tenon?

[@woodwhisperer]

Maybe a tad short, leaving room for glue/error. No major strength benefit to bottoming out.

[@rafah4329]

The Wood Whisperer thanks for the response. This will save me a lot of time on having to either round out the tenon or square out the mortise.

[@thingschangs2472]

from iraq well done
