Just watched this YT video of the restoration of a fractal vice, I'd never seen one of these before, but I think I need one in my life.

Brilliant Jase! Thanks for posting.
Skills to die for
Kit to kill for
. . . and I want one too!

Some bit o' kit.

I want one.

Hi All,
Add me to the list *dribble*
I wonder why they or similar vices did not become popular
I would think that they were very expensive to make???

And even more expensive to buy, hence not in everyone's garage.
Been searching eBay and the net for one, nothing yet.

A fascinating tool and video. All that AND the guy has a sense of humour.
I suspect the original design and manufacture was denied the benefits of CAD/CNC, which wouldn’t have helped with costs. The patent is dated 1913 after all.
-
Only ever seen one in use before, and that was many years back in a tool room and being used by highly skilled fitters.
As the video shows, it's used for gripping odd-shaped objects for machining without using excessive gripping power to hold them. Also as the video show, they're too susceptible to accidental damage in use.
-
Wow wow wow!
I just devoured that video.
What an amazing piece of kit.

I've just subscribed to his Chanel, he does some nice flics.

that reminds me of a vise a had years ago, it's back jaw turned 360 and it had two 1 inch guiders as well as the screw. it had normal straight jaws but you could turn the back bit and there was half circles of different sizes and triangula bits in it. i have looked on the interwebby thing and can't find one. i took it to work when was rebuilding betsy in 1980 and got the fitters to drill it and peg it because if you put something in one side to get clearence it would make the back jaw swivel and end up not holding the piece properly,----------------------- i sold it at a car boot in the 90's so i could go to the pub!! *beer*

G'day Minto.
Wow, never seen one of those. How handy would that be in various sizes in he drill press/mill or bolted to a face plate on the lathe.
Thanks for posting.
Cheers

Can't get this thing out of my head! None out there, and if there were, probably an arm and a leg plus extras to buy . . . .
Was bored yesterday, so decided to try to create an extremely primitive and very simple device with at least some level of adjustability.
Having discarded the idea of a load of sliding pins through each jaw (which I really like, but can't do owing to the hassle of clamping the thing up using hydraulics (if only!), some sort of cam action or even a powerful electro-magnet), I just attacked my cheapest Chinese 4" machine vice, drilled and tapped holes for c/sunk screws, and slung it together.
It does actually work, within the limits of the shallow jaw depth and the fiddle of adjusting the screws, and will certainly hold quite a few odd-shaped items for drilling and tapping. Swivelly and/or curvy bits of eg brass on the operating ends of the screws would be nice too, might do something on that later. (Different screws could be knocked up for particular jobs - but I just used what was lying around.)
Anyway, a pic to amuse - and suggestions for 'better' (within the limits of a home workshop!) would be very welcome.

Whilst I'd like to own one of those fractal vices, (they are a piece of art) life is too short to consider making my own. Good luck with the project.

Just amusing myself Neil really, waiting for a shy sun to deign to show its face and for the clouds and wind to b****r off somewhere else. Praying for a decent weekend, as quite a lot of bike miles planned - but the omens aren't good sadly.
I couldn't dream of being able to make even the faintest approximation to a proper tool . . . this was just a spare afternoon spent drilling and tapping holes in pox-ridden Chinese cast iron. I only had a limited objective, but maybe not much more than a mirage for all that . . . It's the journey more than the arriving, I keep saying to myself!
-
Hey Groily, nice one.
any chance of uploading a vid to YouTube of it in use? I've got a spare machine vice that's just begging to be b**ggered up.

Hi Jase,
Don't know how to do vids I'm afraid, but a pic or two for you. Was going to send as a PM so as not to bore the rest of the world and its wife to death, but when I got there couldn't see how to send pix on PMs. Sorry, R o W!
Works OK for what it is - the grip is easily strong enough for drilling and tapping (with support under any bits that are in mid-air perhaps). It's maybe OK for light milling at a push depending on shape/material (almost certainly not steel), we'll see! The items here don't need anything 'doing', they're just things that are lying around.
I am going to have to get pivoty pads onto the ends of the screws though somehow, so they grip at an angle that matches the workpiece. Will probably need to contrive a selection in fact, owing to there being only 4 screws a side, and horizontally-aligned due to shallow jaws on that particular vice.
Deeper jaws and multiple layers of screws with swivelly brass pads on their noses would be more useful. (Which was why I liked the idea of a load of steel pins in each jaw, to take up any shape, full depth as it were.)
Silly exercise really, I know it is, because I don't have the skills to make something seriously good - but it amuses me all the same (it's raining again) and you never know, might even come in useful!
Cheers,
Bill

Groily, that looks like it has a thousand uses as it is, nice one. I'm definitely going to adapt the little machine vice I've got in a similar way, but maybe as you suggest have a second row of screws beneath, then a box of odd shaped lumps of steel with shallow holes drilled to fit between the screws and whatever work is being held.
-
The problem, as I see it, is having a vice to hold the vice jaws as you drill them.

A new version of which came first; the chicken or the egg?

While lathes are about the only things on the planet without DNA that can replicate themselves, in part, a vice (of the non-bedroom sort) sadly doesn't qualify!
(I always tell the grand-kids it was the Chigg. They know I'm really dumb, so appreciate the confirmation!)

Why do Americans have to keep altering the English language? What with potato chips becoming crisps, bumpers becoming fenders, bonnets becoming hoods, boots a trunk .............. The thing on my bench is a vice, but if transported westwards it becomes a vise. Why?

'Vice' as in advice, ice, nice, rice, advice.
'Vise' as in advise, rise, advertise, circumcise, comprise

Anyone who watches Countdown (CH4 2.10) will know that we are as guilty of altering English as anyone, not that I'm in favour (favor).
My pet hate at the moment is the Westminster mob who continually pronounce "to" as "tu" - next time a government minister is on just listen out
-
Over here in ‘stralia we are so screwed being heavily influenced by both Pommy and Yankee cultures to the point now where the perfectly serviceable crisp has been replaced by the new fangled chip which then has to be distinguished from the fresh cooked version (aka fries) by an adverb so we now have “hot chips” for chips and “cold chips” for bloody crisps!
Now for my current pet hate of a made up word….drum roll…this goes way beyond just a revised spelling… how about “normalcy” for normality. *pull hair out*
"Vise" :o
You asked for this Richard *smile* although I will add I heard the other day and this is not easy for me to say but apparently the spelling of aluminium by us Poms is actually incorrect and the original term was in fact aluminum! (Something to do with its position in the molecular table, so it doesn’t fit with the heavy metals like palladium, rhodium, chromium, Californium etc.
-
This thread is going a tad off-topic. However, I'll submit, 'Burglerised'. What next, 'Burglerisation'? 'Burglerisationism'? 😜
-
How about antiburglarisationalism.

"but apparently the spelling of aluminium by us Poms is actually incorrect and the original term was in fact aluminum! (Something to do with its position in the molecular table, so it doesn’t fit with the heavy metals like palladium, rhodium, chromium, Californium etc."
So where does magnesium (delete I's as necessary) fit in?? Or unobtanium? Or Abittrickytofindium?

Well, someone went to town and has made an impressive 3D printed version. Remarkable I think, and all 'open source' so - ahem - 'anyone' could do it! (Wish I could!)
