Paul,
You now ,have actually sent me back to the drawing board.
But that's a good thing, thank you ,you saved me some timber and time.
You brought up a good point about vibrations(wobble).
Although my initial idea ,I thought was capable of handling the forces opposed on it
Immm maybe not.
This may certainly be a point of more is actually better.
My initial idea in a basic form, a piece of timber roughly 100/100 mm 300 mm tall split down the middle ,re joined to become giant vice jaws with a scissor action screw.
Sitting on a ball and socket joint.
On a heavy base.
Allowing the whole thing to swivel and tilt around.
I really should sit down and learn sketch up lol
As long as I'm buying balls before 9 pm on Friday night.
I don't think I be raising any eye balls on the home front.
Hope that makes sense.

I think the fundamental issue is actually leverage. As you go taller with your device there is increasingly more potential for some bending moment. If you also introduce joints ( balls, sir, in this instance) that potential is increased.
It's a catch 22. You want a variety of angles so multiple positioning is incorporated, but you also want rigidity which is not compatible with the former unless you make the device either massive or with some positive locking as opposed to clamping.
I'm afraid that is not very helpful as I am purely highlighting the problems and not providing the answers.

Paul it is getting late,
But please be careful about your choice of words.
Especially if you re read from it's a "catch 22"
To your next paragraph.
If I had had a few drinks and was back traveling England again in a back water pub.
We would be in stitches lol lol [emoji849][emoji849].
But yes it's not very helpful but so very funny.
Cheers Matt

I have indeed re-read my post. In fact I think the whole post may have an alternative meaning . However I must protest my innocence and declare, this time, I am the victim of my pure mind and the vice of the wide world.
As to the drinks aspect, in very pleasant English country pubs or otherwise, I would draw your attention to this piece:
"Let schoolmasters puzzle their brains
with grammar literature and learning.
Licquor I stoutly maintain,
gives genius a better discerning."
Having been derided to an intolerable level I am going bush for a couple of days where I will ponder the principle of moments and how to avoid unintentional ambiguity! Sun Tzu, where are you when I need you? Get your sniveling, devious little self up here. Now!

Paul,
I have decided to cleanest my soul
From this post forward I will stop drinking gin at 3 am while reading Marchese De Sade.
Sun Tzu should be most pleased with my new outlook.
And I will try to unravel my vices
Once this blasted winter passes

Just a small update on my latest vice. It is rock solid in use. I keep a small offcut of saw plate handy to place in the slot in the handle. This way I can clamp the vice as hard as I like without fear of breaking the handle.
I have only used it for sanding so far, but I wish I had had it for clamping during filing operations on new handles. I now alternate between this vice for when I want horizontal operations and my standard bench vice for vertical operations (I'm hoping you are not going to read too much into these practices ). I may have to talk seriously with Sally about some of your interpretations.
I have just finished sanding one of the D-23s for the sloped gullet comparison and it went so well that after downing an alcoholic beverage I am going back out to do the last one (the fifth)! That is unless the alcoholic vice overtakes the saw vice.
Regards

Paul,
That is great to hear your happy with your new vice(I'm trying to stay serious here).
Yes a bit scrap saw plate in the handle is a great idea.
I nearly broke an early attempt at a handle buy not having a piece in there[emoji20].
I'm still wanting something I can easily clamp a handle in, then move it around so I can get at the handle more easily to shape or sand.
I'm at the Melbourne wood show over the weekend so might see if there's a carving vices to check out and steal ideas from.
I think Sally's has stopped trying to steer me straight [emoji849][emoji849] tho I do get concerned that one day her eyes wont fully roll back.
I also find taking the alcoholic beverage to the bench.
Is far safer than walking back from bench to house to re fill.
Gin and tonic with a hint of silky oak is quite nice.
Or my new favourite cider dirty granny(yes it's called that)
With a touch of steel is nice too.
Cheers Matt
There's a boxing matching in the sharping section I might go see a bit more of[emoji12]

Have a look at The Carbatec stand and see if they have one of these:
https://www.carbatec.com.au/clamping...es/parrot-vise
I purchased one a few years ago (on sale) but haven't used it in anger yet as I'm waiting to mount it on a 2nd hand Wilton Pow-R-Arm I picked up a while back. Still on the to do list I'm afraid.

Talking of the carvers' vice I remembered I saw Don Powell with such as device at the Maleny Wood show. It is probably exactly what you are thinking of, but it definitely moved under the pressure of the carving tool. It didn't worry Don one little bit, but I want something much more stable. Horses for courses I suppose .

Some links for you. A video which might give you some idea for the rotational side:
https://www.youtube.com/watch?v=5alEkTR4_cA
All the carver's vices seem to rely on the work piece being fixed to the vice by a screw. This is not very satisfactory for a handle unless you leave a sacrificial extra tab of timber that is removed at the end of the process.
This might be an idea coupled with a swiveling vice:

Plus it would present the opportunity to make up one of IanW's timber threads in the process.
This might give you some ideas and would not require a lot of embarrassing explaining as to what your shopping list contained:

Tools & Tips Page 2 - Cedarstump.us
This might be a logical development and you can still have a wooden screw too!

Enough from me. That should take care of any free time up until Xmas .

Paul,
I'm feeling slightly squeezed under all that excellent information.
It will take a vice like grip to get through it all
Thanks for that great links and ideas.
Cheers Matt

Matt,
cheap and simple...
small vice fixed to a flat board, then into the bench vice.
I throw it under the bench when not in use.
Surprising amount of flexibility.
Cheers,
Peter
