Fractal vises are apparently a thing?
ebastler:
Neat idea! But would I dare to file or engrave anything clamped in these jaws? The mechanism looks like it might take offence when contaminated with metal dust and filings?
Kjelt:
For one offs engraving weird shape object it would be great.
Engraving doesn't exert a large force. Also I think the clamping force could be large since the contact points are smaller than a regular vise.
For multiples on an cnc machine it will IMO not be suitable since there is no fixed reference side as is with a machine vise.
So the next object could be shifted in a random position after each clamp.
CatalinaWOW:
My uses would be for general purpose bodging. Nothing precision, but just holding a part or tool while doing rough filing, sawing, drilling, grinding or welding to customize or repair it. Farmer machining, not precision or production work. Obviously the vise in the restoration video had received a lot of this kind of use. And unfortunately it is hard to justify investing a lot of money in that type of work.
coppercone2:
someone should do a test with a heavy hammer to see how well it holds up to determine what operations are safe, you can be as imprecise as you want and drift does not matter but you need to know it will not fling things, especially with angle grinders
I am seeing a smooth cylinder contact surface
