thanks for the review, just what I wanted to know.

Looks like a fantastic deal! I've been very happy with everything I've ever bought from Accusize.

I've seen videos showing these used on the mill but you can't get the same clamping pressures as a milling vise with a screw give. I've seen warnings of the same. And just a recent experience on the surface grinder where I was grinding something too tall for the short jaws of the vice, and it rotated into the wheel. And there's not the same machining forces. That v-groove at the base of the fixed jaw is to provide the space for when they grind that face square to the base, as the wheel has to over hang if you want that bottom corner edge to be ground with the face. Same with your V-blocks, you need clearance for the wheel. It does give clearance for the work that may have a burr. But look at the moving jaw of the vice, there's no place for a burr. I just wish I could get as nice of a surface finish as that vise you've zoomed in on (nice camera work!). Just last week I purchased a Mitutoyo 1 micrometer test indicator. Now I can see the issues with my grade B surface plate, and what I thought was a perfect cylinder reference gauge, is now in question, is it the gauge or the surface plate. Making one of these, would be very hard to grind that sliding jaw bottom groove feature to fit and slide perfect with no slop. I'm a hobbyist too, and I know darn well I'm not a tool maker skilled sort. Nice review of the vise.

Thanks for the great info. And I suspect the grinding in those recesses might be made with specialized grinders. Its amazing workmanship. Regarding the grade B plate they’re still quite accurate but truth is few of us work in temperate controlled environments etc. Rob Renzetti of ROBRENZ demonstrated how just touching a micrometer, a part or a surface plate affects the reading. Pretty cool stuff. So I keep reminding my myself that I’m not producing stuff for NASA. I like making tools and will continue practicing because it’s fun. 😊👍🏻

@@LetsRogerThat Robrenz is at a crazy level of precision. Mix that with his electronics skill, and nothing is flat. I've been watching videos on regrinding Vblocks, as I found the ones I got from Enco (now out of biz and part of MSC supply, here in the states, and too pricey for my hobby expenditure), came from India. They are flat as seen on the surface plate Vee side up, but the sides rock, and can't be used for perpendicular work. So learning how to properly put them in the grinding vise to fix this is one of the minions of projects in the que. It's all just a hobby. But it all originated back when I was in primary school, and metal shop had aluminum foundry, and a South Bend lathe, that I seemed to be the only guy wanting to use. The bug stuck with me. And now the metal shop looks like a hoarders den.

Not arguing but Stefan Gotteswinter has used a vice of that type on his mill quite successfully and if its good enough for him, no more need be said 😊

@@chrisstephens6673 Which video is he doing that in? His most recent video on making a micro annular cutter, kzread.info/dash/bejne/qmqAt9KiZrqZiaQ.html&t (about 29 minutes in) he certainly did use a precision grinding vise on his mill. I think because he needed that v-block horizontal groove in the jaw for the plastic part he was machining. Very light machining forces. I liked his response after he machined the part, of how elated he was that it worked. Or did you see him machine some harder metal in some other video? I just listen to the few channels I watch of precision grinding, Shadon HKW, Solid Rock Machine Shop Inc., and others that have said this. I know you can torque down on the clamping screw, but it's putting nominally 1/2 the screw force downward. And with the very smooth ground faces of the vise, it's pretty slippery to holding iron with high cutting forces in place.

@@f.hababorbitz I seem to recall him using one for as long as I have watched him and that is more or less since he started. In fact I don't think I have ever seen him use a "normal" milling vice. If your time for watching videos is limited and you want to watch the best, Stefan, Robrenz, Adam the machinist( that's not Abom), Inheritance Machining, Joe Pie, Mr Crispin, and if you are interested in surface grinding and squareness Solid Rock machine shop, there are many others but they tend to be self taught or do a lot of product reviews or box opening but the above are professionals and their knowledge is usually well expressed.
