I saw this picture of a fancy mortice and tenon joint and was facinated for one how it looked and also how was made.

I “fiddled” around with a protractor and some old packing crate timber and then calculated how to make a jig to the do the cut outs for each end of the timber, at this stage no M&T will be done, not just yet anyway just yet one step at a time.

I made a jig to hold the wood at 60 degrees and then I needed the ability to slide it across the saw blade to cut out the notch.

All a bit crude but this is what it looked like

Then on the fence getting cut out

The three pieces are screwed together and then the lot screwed onto the jig.

Set the height and mark the stop start points and away you go.

Take it off the saw remove all the screws and reassemble as a joint.

This is one side:

And the reverse:

I did another to remove the open triangle, but must have not paid enough attention as to what I was doing, as they would not fit.

The overall layout plays with your mind a bit as the center line is actually the edge of each timber.

With a bit more attention and possibly tidy up of the cuts you could make a pretty decent close fitting joint.

Hello Big Al and Candy,

Its certainly an eye catcher, I am still looking through the web trying to find a name for this Joint, its got a destinct Japanese look to it.

No doubt with the M & T included as well the complexityand assembly would increase and some jiggling to get it together would be needed.

Lotta fun doing something else beside fixing my roof tiles for a change.

-- Regards Robert

Nice work getting the angles to work. It’s like connecting three rafter bird mouths together.

Robert, I know I’ve seen a Japanese name for that joint – I think it was on YouTube, but I can’t find the vid again. It’s been used to join stringers on three-legged tables and stools (though less common than the three way bridle joint or three way lap joint). I would call it a three way scarf joint, but that term doesn’t seem to be used, according to the googles.

You know what guys, ... I am really kicking myself about the original picture, I screen captured it some time ago, and I was cleaning out stuff when I found it, decided to make a couple of modified versions of it
Went looking for what it was used to support the blog,r and as of today still cannot find its name, application or where I saw it.
I agree wirh Dave its in the Japanese line for sure and as he has seen the name that confirms it.

My research will continue and hopefully I will “discover” all the facts and report back with them.

Thanks for the feedback.

Don and Larry Hey if its not Hurricanes its Bushfires dropping in and creating surprises for you all, I sincerley hope you are out of harms way this time. I still remember the stories Rockwell US staff told me when they were here working with the Australian Submarine project about earthquakes and bushfires i their home towns.

LDB, I wonder can you post some pictures please as I am seriously thinking of stimulating the grey matter with some performance enhancing products. My last effort made the legs wobbly and I am not talking about the table either, but it felt good just the same.

A bit of idle chatter as well, in Lillydale Rockwell had a manufacturing plant on the Maronda Highway and Sheep road, I cannot find Sheep road on Google any more, do Vic’s change the name of streets and suburbs regularly? Lillydale is not for from you? correct. Mind you I was 45 or 46 at the time!

That’s a very strong joint Rob but way to complicated for this simple toymaker…

Huh. One of the few pieces of furniture I can find now that’s built with this joint is in the Les Sidetable by Lee Sinclair Design Co in Brisbane. Maybe it’s some sort of down under thing.

Could always ring them up and ask them what they call it, Robert.
