Nevertheless Bill, you are suffering from a common complaint,. you think

That's exactly what you do all the time. You're notorious for it.

Those of us who
have done this for a living and studied it at university know it aint
that simple.

Oh **** me! 'I've been to Yooni so I know everything, and I certainly
know more than those guys in overalls down there on the site!' How many
times have I encountered this blinkered, arrogant attitude? Architects
who won't listen to the tradesmen being a good example.

Fact is, a guy who's spent his life making things from wood knows a damn
sight more about how to make a gate that than someone who thinks they
know everything because they're been to Yooni.

I discussed this issue with two people. One was a bloke who worked all
his life in joinery, first building wooden wagons and later in a
workshop turning out various wooden products. The other was a woman who
runs a very successful business building furniture and fitting out up-
market new houses with doors etc. Both thought the idea of making a gate
or door with the brace the wrong was round was such an elementary
mistake they wondered if I was joking. So don't give me your high and
mighty Yooni ********. I've been putting up with that ****e all my
working life and it won't wash.

Bill
yu remind me of the plumber who came to connect up my UNVENTED hot water
tank

"In the loft: great place to put it mate, it will increase your water
pressure for the showers"

He, too, did plumbing for a living.

You cling to your beliefs and myths in the face of the simple evidence
that no cantilevered structure can exist without at least one joint in
tension.

you insistence that it mustn't be the diagonal joint is simply arbitrary
and bizarre

Looking at how a wooden gate is made:

1. Given that you need good joints at all four corners, it is not hard
to make the top ones capable of reisting tension with no additional
work. A diagonal brace in compression needs hardly any jointing at all
as it has vertical and lateral compression forces against its trianguar
end and just needs stabilising in place with a very simple joint or
metal hardware. So you save two elaborate carpentry joints.

2. If the diagonal strut bears on the uprights as well as the
horizontals it should be possible to distribute the tension between all
four joints, and all four main members,

I am sure there is a reason why gates are made with wooden diagonals in
compression, or, as I have seen, steel cable diagonals in tension.
