Does turning the handles actually propel the vice in and out or just lock it? It seems that it is just a sliding face that can be locked at any position.

Dunno. But I bet that if he has gone to all the trouble of design and redesigning something like this, it will work well, especially if he plans to charge a premium price for it.
My guess is that it works in a similar manner to a trigger clamp, but using a trad vice bar rather than a trigger.

looks damn good, and considering that when you buy a bench 1/2 the cost is in the vices, thou'if youbuild your own, then the timber costs about 3/4 of the bench and the hardware 1/4.
If I win a lottery then I'll buy a couple of these new vices

At $350 they should call in the vise squad!!!
Seriously...that is neat...very neat!

Has anyone found the patent for this vise?
Twin Screw Vise reveals only two older patents held by Lee Valley
and 'hovarter' as inventor does not find it.
Vise and Michigan draw a blank too.

Thanks Steve.
I'd already found those patents in the name of Hovarter but the vise one seems elusive.
I'll keep searching

I may be dumb (don't bother answering) but why are we talking of patents when this is essentially a very upmarket version of the clamping system of every portable folding workbench; Workmate et al.? Or am I missing something?

Well I guess most of us find it fascinating that the bars are not threaded, yet it obviously holds well. I, for one, don't understand the details of how it works, but I'm pretty sure it's not at all on the same principle a a workmate., which is a simple lead screw.
Perhaps it's me who's missing something, but it looks revolutionary to me.

Hi,
Looking at the last pic of the mechinism there is a large washer at an angle to the cog next to it, and a spring behind it, I think it works like a quick relese clamp but operated by the rotary motion of the bar, somehow, I haven't worked that one out yet.

Hmmm... I think the transfer bar has a wedge profile at one side, which skews the big, spring loaded washer to a locking angle, then, further rotation drives the bar backwards. Very clever, and the sole reason for using the transfer bar rather than the traditional chain.
[Edit] Hold on, that doesn't totally explain it. How does rotating the smooth bar rotate the pinion that moves the transfer rack? My reasoning has hit the chicken and egg wall here.[/Edit]

I'm wondering if the pair of bars have keyways in them to drive the gears and yet allow sliding action.
In the video we only see the bars rotating about 1/2 turn and then only a clear view in the unlocked position so there could be a keyway on the underside of each bar.

I'm waiting for Bugbear to declare that this is just a twin screw face vice so a well old idea.
Clever, very clever, very slick, however.
But, it doesn't achieve anything that can't be done with a couple of Records for under £100.

The gear is out there to make your own at a fraction of that price,if you want me to direct you to it?
Its very simple in design,the gear part of it is just inside the table just after the clamp part itself,the rods end about 1" away from the back of the table.
Anyone with an enineering backround will suss out how easy this is to make.

Yep.. But not having a full engineering background, to me it's like every other 'Eureka' invention. One of those things that's so obvious, with hindsight! The solution was there, but someone had to dream it up! So simple that it's been overlooked for as long as it's been needed.
So yes please RR, direct me to these parts? I am in the bench making stakes at the moment, so I can weigh up whether it will be better than Jake's. Two Record Q/Rs might look a bit more clunky but they do the job.
BTW Jake, just think; this guy might have seen your idea and developed this from that!
