I just came across the Kreg MortiseMate (Domino knockoff)

Every DF owner I know uses their machine to build furniture and cabinets. This is the first time I saw it used in stairs:

Any Domino killers capable of doing it as efficiently? [big grin]

A major anything-killer in the UK would be the rather inconvenient matter of Building Regulations (=code in the US). Treads and risers have to be fully supported along their entire length = stair stringers and tread slots routed at least 15mm deep, with no more than 1mm of axial play in any plane.

So it means as long as the smallest dominoes (4x20) aren't used, it's ok?

Our local code requires 200 pounds of resistance before failure.  I’m no sure exactly how they measure that.  I made a custom railing and put a bathroom scale against it and pushed until it registered 200 pounds.  So I am calling it “in compliance”.  If an inspector comes, we can argue about it.

Reason you are seeing these flashy titles and thumbnails is creator's way to make people watch videos   thats all it is. 

Yup. I know a writer for a financial website. He wrote two similar articles. The one with the clickbait headline got 118k views; the one with a real headline got only 2.7k.

How long will it be before the audience learns?

My understanding is the Lamello connectors, like the connectors I linked above are not structural. They just pull panels together. 

Generally yes, the main appeal is that Lamello connector's holding force is amazing and pulls joins tight without needing clamps, especially with the Clamex's, but I do use Domino's along with them for anything large or structural to provide the rigidity I want.

Having said that though, if you only use Tenso's for face frames or similar, and you glue it as recommended, there's no way that sucker's ever going to come apart! It's there forever!

From a point within 2" from the top, push down.  As a separate test push sideways.

I only tested pushing out.  This is on my deck, same requirements as indoors.  A 15 foot drop, and the you roll down a hill for another 15 or 20 feet.  So I overbuilt to be safe.

Historically I used the Rockler Beadlock system and it produced very strong joinery, but as others have well said it was tedious. I was therefore very pleased to move on to the Domino, which as we know has no competing "killer."

The Wood Whisperer has been around for a long time and I respect his insight. Alas he too now needs to bend to the YouTube "click-algorithm" and thus the semi-deceptive video title. However he still applies his rather scientific analysis which I appreciate.

Kreg has many good products which I regularly use, but this does not appear to be one of them, as again I would favor the Beadlock at that price point.

In the video Chuck linked, the guy is only using Dominoes to add spindles to the ends of already secured open stringer stair treads. I don’t think the strength test applies here.

Snip.

YouTube is making some people rich (just like Tik Tok; I read somewhere that some TT tweens can make a lot more than someone with an engineeing degree or the like), and sometimes, people who want to stay afloat need to stretch the limits a little. But even in the traditional, non-social media segment, people play with deceptions to promote their companies or business:

P.S. I just looked at one of the content makers I check out now and then. He started using flashy, big font titles a few years ago. At its height shortly after that, one of his videos scored over 2 million views. Then things resumed normal quickly with views ranging between 50K and 200K. In the last three months, the average views have been 50K or so, despite the continued use of "big" titles or captions. Substance, not marketing gimmicks, rules in my book.
