Today I’m testing the strength of the Festool Domino VS traditional mortise and tenon. I was really surprised by the results and had a great time breaking into Shaun Boyd’s shop and stealing his Festool Domino. What do you think of the results? What would you like to see me test next? Thanks for watching! Please like, comment and subscribe. Cheers!

I really appreciated you taking the time to put out some free, structured data that is certainly useful if not merely interesting. It was done as a favor the community and you deserve thanks instead of misplaced criticism.

@MNhockeydude35 5 лет назад

I have seen a lot of these tests and it seems to me that the failure of the domino is always related to it being so short. I personally dont think 25 mm going into end grain is not sufficient in high load applications and it usually always fails on that end. I do have the domino XL and really enjoy using it not only for the strength of its joinery but more than anything, the accuracy. If I need a particularly strong joint I will make my own 100mm dominos out of scrap that I have on hand. If a joint is hidden I will use a domino because of the speed. All that really matters is real world application. I have not had any fail and that is really the point isn't it? That being said, I feel that the stock dominos could be much longer in many applications, I would prefer a 70mm domino. A test I would like to see is how much more strength a double domino increases its strength over the single. In many applications two smaller dominos side by side increases the glue surface area and can be implemented over one larger domino.

@Domith81 5 лет назад

I am well versed in critiquing research. I appreciate the fact that you used the CNC machine to make several T&M joints. Your conclusion that a domino is weaker than a CNC made T&M has one problem that you actually mentioned at the start of your video. When you made the T&M by hand (which I imagine most of your viewers are going to do) you had inconsistant results. The technical term for this is "generalizability," meaning the ability to apply your results to another project. So unless your viewers are using a CNC to make their T&M they should not expect to consistantly have 20% stronger T&M compared to the domino. Solution, use four groups: Group 1 domino. Group 2 experenced woodworker made T&M. Group 3 novice woodworker made T&M. Group 4 CNC made T&M joint. Another interesting finding to measure would be a time comparison for how long each joint took in each group. i.e. domino could make 10 joints in 3 minutes vs experenced/novice woodworkers etc.

@SilverbackWoodworks 4 года назад

is there any issue with the test criteria considering that the M&T joint was pine/pine and the domino is beech into pine? I think you would expect to see wood failure on the domino where you would expect tenon failure on the M&T. we could have anticipated that, no? im expecting closer comparison if all of the materials were the same wood.

@gavinfeargrieve4874 2 года назад

I've been asking myself the same question ( M & T vs D) for the last year. I'm absolutely thrilled you took the time to answer this question for me , and with a convincing "scientific " approach. Thumbs up for that. I am biased toward M & Tenon, because of the long tradition and beauty of this joint. However, ya can't beat Dominos for speed and if you're running a commercial shop it's become an essential tool. That said, I think they're both strong enough joints that visual appeal in design becomes the deciding factor. Thanks, you're the best!

@craftedworkshop 5 лет назад

Cool test! I think this would have been much more useful if you’d used hardwood rather than Pine. Who uses Pine with a Domino? 😂 I’d imagine the Beech Dominos didn’t play particularly well with the Pine. I’d love to see a round two!

@terryfigel8261 2 года назад

I would be interested to see that too, but in addition can you also test butt joints(no tenon)? I would like to see that. I think this was a really well done video!

@ChetKloss 5 лет назад

For me, once I determined the domino was more than strong enough, the rest wasn't relevant. The Domino allows for very strong repeatable joints made relatively quickly. That is where it's value is for me.

@mattcooper7550 4 года назад

Chet, hopefully you'll see this, but can you use a domino on things such as building a couch for outside? will the joint be strong enough to a) hold up to people sitting on them b) will the joint fail because it gets hot as hell here in AZ? Thanks.

@GregLohr 3 года назад

@@mattcooper7550 The Domino is mainly a tool for making identical mortises quickly and easily. It's nice that you can buy their pre-made tenons. But you could make your own tenons to fit the Domino mortises much more easily than you could cut all those tenons by hand. Does that make sense? The point is, how you cut a mortise doesn't affect whether it's OK outside. For building a couch outside, you need to use wood that can be outside and then give it a finish coat (sealer or paint) that will add protection. And you want to size the mortises / tenons appropriately to the size of the couch lumber and joinery. If the Domino can't cut mortises that big, it's not the right tool for the job.

@williamlaird2136 5 лет назад

I have only recently started wood working. After several, miserable failed attempts at hand cutting M&T joints and hating the look of pocket holes with screws, I went out on a limb and purchased a Festool 700. Expensive, OUCH! But I have the knowledge that my cabinets don't have any metal in them and are a huge step above commercially made cabinets. Even with my mediocre skills I can make a joint that is all wood and has what I think is strength enough for anything I will be making. I am not willing to make any chairs yet. The pantorouter/CNC machine you used for your M&T joints, financially and logistically is beyond my means. I do not have the space and cannot justify the cost of either. Your dovetail jig is a wonderful tool and I have only practiced with it a few times. I will be doing some drawers and will try to make your jig work. Great video and an absolutely important question answered. Not what I was hoping for but the knowledge is very important to have.

@davidness7523 2 года назад

If the domino failures were caused by the pine board failing, then is test proves the domino is stronger than pine. Wouldn't it be better to use beech (I think that's what the dominos are made from) for all the components? If you can't find beech, then use something of equivalent strength.

@bobmedic3214 5 лет назад

There comes a point where strong enough is a factor. You have to weigh the difference between strength and speed and mobility. I have both of the Domino machines and I still use a Kreg jig where applicable. Like face frames, I use pocket screws because they are hidden and I don’t have to clamp it. Saves time. Doors or other joints that are visible, I use Dominos. Some joints are made for their strength and aesthetics. Like dovetails, through M&T and lap joints. None of those options are faster or as mobile as the Domino. You can also use a Domino to add strength to other joints like miters or cope and sick joints. Much more difficult or time consuming than using a Domino to add splines.

@GregLohr 3 года назад

A craftsman doesn't always have to choose speed over quality. You can have both. This video, as interesting as it is, doesn't scientifically prove that the Festool Domino is only about speed and not at all about quality.

@rsilvers129 2 года назад

Thank you for the video. Two things. First, I would like to see someone compare a single Domino strength to simply using two 5 cent Lamello Biscuits on top of one another. No one has done that. Even a clone Domino is 17 cents. Second, I used calipers and measured the thickness of 30 each of DeWalt and Swiss-made Lamello plate joiner Biscuits. Lamello was 1000 for $46.37 from Amazon, which is 4.6 cents each. DeWalt was $7.98 for 100 from Lowes, which is 8 cents each. I calculated the mean and standard deviation of the thicknesses and the Lamello were more than 3x as uniform. 97.7% of Lamello are predicted to be between 3.69 and 4.00mm. DeWalt are 3.34 to 4.31mm. The goal is to be as close to 4mm without going over. Visually, the Lamello have a glue-gripping pattern on each side. The DeWalt had a more shallow grid on one side. No sense in judging biscuits without using Lamello brand.

@Bshwag 2 года назад

I built a shed this summer and put deck on it for storing burn wood. I used 12mm dominos and pocket hole screws to hold the floor joists together. I did this because I used rough cut timbers and normal joist hangers don't fit. we proceeded to load 2 cords of wood as high as the awning would allow, to the point that the 10x4 rim joist deflected about 2 inches in the center on a 10ft run. I ended up putting another peer block and support in the middle. But I have had no issues at all with the dominos holding that weight.

@jcsrst 5 лет назад

Interesting video for sure! i've never seen another strength test of dominos. I have a domino and thought long and hard before I bought it. I use mine ALL the time, from small projects to large. I never considered the strength aspect, for me its an efficiency issue. The domino is fast and versatile. I am ok with a machine for a joint that no one will ever see unless they break the piece. I was surprised that it wasn't as strong as a mortise and tenon. I love my domino even if its not as strong a joint. Thanks for taking the time to test them ; )!

@josephdestaubin7426 5 лет назад

We use Dominos in our shop, but I have to say at the Dominos themselves seem to have an inherent flaw. It's well understood that wood glue only has any strength when it is is as thin as possible. The Domino's of course don't really allow the glue to be thin. I would love to see a test using a shop made floating Tenon in a slot cut by a domino cutter. On paper you should be able to get a significantly better result . Chears.

@jasonm.7358 2 года назад

Nope. Check out Matthias Wandel’s test. Wood joints intentionally gapped by 0.3mm were significantly stronger than tighter joints, and joints clamped super-tight to make the glue as thin as possible were significantly weaker, as were joints where a dry tenon was inserted into a glued mortise (which _looks_ like how these Domino joints were constructed). So, when you say “it’s well understood “, like gluing endgrain, you may find that what is commonly _believed_ is not necessarily _true_.

Nice test. Logically the Domino is floating tenon and the M&T has the advantage of essentially infinite grain strength in one direction. A cool variant of this test would be to make pine Dominos at longest length the Domino will drill and test that against M&T. Got me with the "jack" callout 😂

@John-ye4nv 2 года назад

Ok - this comment is late. Just found your channel and have skipping around until I saw post. Domino has two fits. Loose and tight and you choose that when you make mortise. You didn’t say which setting you used. The fit between the mortise and tenon - or the domino and tenons will impact glue volume, insertion depth, and mechanical advantage. Moreover the fit depth, unoccupied volume in mortise coupled with fit clearance will also have an effect. Love the channel.

@barryirby8609 2 года назад

I appreciate the test and the effort that went into it. Would like to see some variations. Like using hardwood. And shop made hardwood dominos. I am betting shop made dominos would be stronger based on improved/increased surface contact for the glue. Unlike you, I have the Domino but not the CNC. It seems to me that the CNC would slow down one off type projects a lot over the Domino, if you take into account the programing time. Thanks again...one more time...

@Wood_Slice 5 лет назад

Just a thought. The mortise and tenon as same wood species (pine im assuming) whilst the domino wood species might be a hardwood (not sure). That might throw off the result

@GuysShop 5 лет назад

Nice test Jonathon. I actually am not surprised at all given similar testing I have seen in the past. That being said, either dominos or M&T will give you more than enough strength for 99.9% of furniture applications. I have projects that I built well over 20 years ago that are completely held together with biscuits. Which are probably less than half the strength of dominos. Thanks for posting this!

An idea for another episode perhaps or have you already done it? Cheers and keep up the good work. Looking forward to the arrival of my stop block and dovetail guides; sometimes international feels like it takes an age.

@grahamparsons6620 5 лет назад

Very interesting results, I thought it would have been a bit closer to be honest but you can't beat the science. Since I don't own a domino and can't afford to buy one it cheered me up no end to see the results 👍👍👍👍

@Martin1519 11 месяцев назад

What if the grain of the mortise and tenon were parallel to each other, how would those stats differ? Example, gluing the ends of two 2x4’s together with a Mortis and tenon joinery. Would it be as strong as a 2x4 of the same length without a mortis and tenon?

@NeoLifeless 2 года назад

I had heard the surface of a domino you buy is not as smooth as one you’d make. Lettering or some pattern, which weakens the joint. If that’s true might be cool to add in some smooth diy dominos.

@--JD-- 3 месяца назад

The hardwood (beech) domino cut through the soft pine (that's why they didn't break), the M&T was both the same Pine, moe elastic and in the end, broke the tenon; therefore the different results. Willing to bet that we a have test setup failure here (apples & oranges).

@hydrophobicgoldfish 3 года назад

Results were similar horizontal to vertical because of the square profile. Try rectangular profile for comparison...?

@TheEveryMaker 5 лет назад

I've been wondering how strong the floating tenons are, this is really helpful. I thought the glue would make them stronger. Very good video!

@Nine2FiveGamer 4 года назад

I wonder if these results are due to stress multipliers created when cutting into the joining piece with the domino. Any 90 degree angle cut into any material will act as a stress multiplier when a lateral force is applied. With traditional mortise and tenon, that 90 degree cut doesn’t exist inside the joining piece.

@janrasmussen4623 2 года назад

just watched the video - although 3 years old, it is still very relevant. But I would like to mention, that one needs to be very careful to compare two averages without doing a statistical analysis to examine, if the average difference measured could be caused by pure chance. A quick analysis actually shows, that with only a sample size of 6 attempts and a 95% confidence interval the average vertical strenght for Mortise and Tenons ranges from 49.9 (+/- 10.8) lbs and the vertical strenght of the dominos ranges from 39.4 (+/- 8.4) lbs. The difference is no where near statistically significant. However there is a minute significant difference in the horizontal strenght test - the average horizontal strenght for mortise and tenons ranges from 51.2 (+/- 6.3) lbs and the dominos from 37.8 (+/- 7.9) lbs. So I don't think you can conclude from this test, that there is an obvious difference in strenght between mortise/tenons and dominos.

@williambranham6249 5 лет назад

I like the test and the caper. I use both techniques. In the real world application I agree that either would work. Since time is money, the domino will win everytime. I do enjoy the challenge of hand cut mortise and tenon.

@systemtim 4 года назад

just point out that the tests are inconsistent because they had different drying times, the domino is made for a different timber for the actual tenon........

@Renegator1 2 года назад

It seems to me that to get a sense of the strength of the joints, it would have been good to place the jack much closer to the joint. The leverage at the 9 inch mark is substantial and greater than what I think the actual forces on a chair would be. On a chair, wouldn't the force be closer to shear? So this gives us an idea of the comparative strengths, but as I am just starting to look into dominos, I am looking to understand their actual strength. But the test was very coo,l and I appreciate the thought that went into it.

@timothyball3144 5 лет назад

Interesting test. Glad that you mentioned the outliers, but I quick look at the numbers, I don't think it would have changed much to toss them out.

@bobd. 3 года назад

I think a larger sample (maybe 9) than 5 units of each type joint would have been better. Then toss the highest and lowest values (which leaves 7 samples) from each set before calculating your average would have been better.

@gregoryvangundy6170 3 года назад

I’m making some maloof style chairs so got interested in buying a domino but I realized the domino’s limitation is the depth of the joint, ie not very deep. Since joint strength is related to glue surface area by almost any method this is a serious limitation. As many of my joined parts will be max 1.5” square and then sculpted I’m going with large hardwood dowels. I’m sure in a production shop a domino proves cost effective.

Have you compared (vertically or horizontally) offset dominoes versus Aligned Dominoes ( or Mortise and tenon). Do you have a video on that?

@clevelandexplorer2221 3 года назад

This is awesome, I had wondered!! But, when you did try the domino, what did you think for ease of use and such, just the handling of it next to mortice and tenons?

@andybrook-dobson726 4 года назад

Loved this JK-M, thanks. Good fun. So a couple of questions: 1) did you get yourself a Domino in the end 2) wonder about a similar comparison test between a domino's mortice & tenon v a standard biscuit joiner. You thought about doing this one?

I just subbed and i really enjoy your vids and your chanel!

@joestafford6255 5 лет назад

Main advantage for Domino is speed. For most of us without access to a CNC, the Domino is much faster then hand-cut M&T. I realize some people, like yourself, can probably cut M&T joints fast enough for that to not matter :)

I think you just sold me on a pantorouter over a domino!

@katzmosestools 5 лет назад

I've used one. Those things are awesome!

@EveryOtherDayWoodWor 4 года назад

Great video. The M&T goes the length of the wood. I think if you used the XL700 withe 140mm domino you would have had different results.

@SkylersRants 5 лет назад

Interesting test. Thanks.

Breaking and entering with intent to Domino ? I got you now sumbitch ! Lol great video Jonathan, Merry Christmas and Happy New Year ~

@sawigginton 5 лет назад

5:00 curious at the scatter of the original attempt, especially given the variance in hand cut (vs machined or in this case CNC M&T). Another interesting experiment would be joint strength vs "slop" for the different domino settings.

@katzmosestools 5 лет назад

Agreed

@xylonguitars 5 лет назад

a very good effort, thank you for sharing. One problem though is that the dominos themselves are of a much stronger material than the pine timber... you would have had an even lower average if the dominos were made out of steel, for example. I would be interested to see what would have happened if beech was used...

@NitFlickwick 5 лет назад

Xylon Guitars this was my thought immediately upon seeing pine being used. The beech tenons will behave drastically differently from pine tenons. What I don't know is if they will fail earlier or later because I can see arguments for both (beech is stronger, but that increased strength may focus the load on the connection with the pine instead of spreading the load more evenly through the whole board).

@johnyhuh 2 года назад

What if the material was a hard wood instead of pine?

@chuckholton4666 5 лет назад

Great video! Shaun, get a better security system! If some dovetail cutting guy can get into your shop it must not be very good.😁 love both of you guys!

@jakefromstatefarm9721 4 года назад

I'm barely a weekend DIYer wood worker so it be hard to justify any domino let alone one over $1,000. A good friend has his shop filled to the ceiling with green tools and tells me the biggest difference between my multi colored tools and his is the ease of set up and repeatability.

take woodwork at school dont know shit about it but these videos are welllll entertaining

@MrJKellerLewis 5 лет назад

There is a similar test video put out by Dowelmax testing their dowels against dominoes. Check it out. It doesn't have any lock- picking though

Interesting, l think all the domino gives you is consistency and speed. It would be interesting to see the same testing after the adhesive dried for a week and was at full strength.

Further research showed that Katz-Moses pizza is better than Domino's too :P Thanks for the vid Jonathan, just goes to show you don't always need the best and most expensive tools to come up with a very good job, learning some good woodworking skills can be just as valuable.

@Tensquaremetreworkshop 4 года назад

Would have been interesting to compare with just a glue joint. Might turn out to be good enough...

@MintStiles 4 года назад

M&T is also naturally tight unlike a domino. You can see this in some chair legs. After a long period of time, the glue seem to work themselves apart. Now this may be just the glue, but a M&T would still be tight via friction on all four corners. If you pin or wedge it... Well that's not coming out. Unfortunately, a chair made with dominoes is probabaly considered a premium feature these days. Most are connected with the thinnest il fitting dowels that they can find. Nothing wrong with dowels, it's just that they always seem to choose the tiniest 1/4 ones.

@Rattletrap-xs8il 5 лет назад

If everything Festool made didnt cost a thousand bucks or more, maybe I'd try it.

@sergeantmaker 5 лет назад

When viewing your domino mortises they looked a little larger than the tenon. Was the domino set to oversized setting or to tight setting? The extra space in the mortise could decrease the amount of glue surface allowing only 2 sides of the tenon to have a tight glue joint.

@sergeantmaker 5 лет назад

I went back a viewed the video again and I take my above observation back; t does appear you used the tight setting. I must need a new prescription or something but during glue up it looked like one of the tenons had a little extra space in the mortise. I freeze frame the tool in use and see the dial is on the tightest setting.

@wwscott7595 5 лет назад

Hullo young man, very interesting test you have just done. Now, if I want to build repetitive chairs, glass cabinets, British style sideboard's, I think you get the picture. I will spend hundred's of pounds and maybe a bit more, I will buy a Festool domino. As I am a wood worker of simple need's and mind I will stick to the other way. Router, good bit Japanese saw sharp chisel's and a marking Knife. Oh, timber. The second way to me is the sheer enjoyment of being calm and looking at my inner self. That's my rant over.

@tomlagatol4448 5 лет назад

Jonathan, I noticed (early on )in the video that the mortice made by the Domino was the looser of the two kinds that it makes. I mention that as that might be a difference between the CNC generated M/T and the domino.... Just a thought. Thanks for the vid.

@katzmosestools 5 лет назад

It wasn't. It was on the tightest setting

@tomlagatol4448 5 лет назад

My bad....Sorry!

@titosrevenger 5 лет назад

Can you explain what's going on in the shot at 2:49? The voice over says you matched the size of the M&T to the Domino, but in the shot it's clearly very loose. It looks at least 2mm wider in each direction. I'm assuming this is just a size comparison to show that they're almost the same size and that the actual tenon fit more snugly than the domino fits in this shot.

@jcsrst 5 лет назад

The more I think about it the more I think your test pieces need to be made out of beech. Dominoes are made out of beech. I think using them in softer wood is the reason the joints broke more easily.

@formekinetics691 5 лет назад

Like to see if dominos could be used on a timber frame.... Something to be said about mortise and tendons.... They been around a long time....and have held up for hundreds of years.

@Eorlingur 5 лет назад

Did you size your mortices to match the tenon or the hole the festool machine cuts? A domino has a different shape than the hole the machine cuts, so there is some play when mounting it. I would guess that a snug fit for the short sides of the tenon would add more bracing area for the glue and therefore make it a bit stronger.

@katzmosestools 5 лет назад

Yes everything was cut on the cnc to be almost the exact same size as the domino
