The vice I use on my mill gets quite a few comments from you guys so I thought I'd start a thread with a few detailed photos.
The vice was made by an old friend who I worked with, he was a grinder in our Tool Room, and the vice was made to use on a surface grinder with a magnetic table, so when I got it there was no way to clamp it to the mill. Its made from hardened and tempered steel and ground perfectly square and parallel, by good fortune before it was hardened he drilled and tapped a number of holes along the base and up the edges, so I able to fasten two 1" square bars down each, side drilled and countersunk for clamp screws.

I also screwed a register bar along the bottom that is perfectly square to the jaws, it fits neatly into the T slots of my mill so that the vice is square on the table.

The stop is based on a thread posted her by John Bogstandard, this is the thread http://madmodder.net/index.php?topic=1007.0

The parallel stop on the right in the photo is just my take on the same idea I dropped on some parallels at the scrappy, putting the work up against the parallel brings it perfectly square.

Her's a couple of pics of the stops in use:-

This one gets the job square as well as acting as a stop.

Very nice vice. I am jealous over that one. Impressive tool... :headbang:
Eric

Yes, I very much like that Vice Stew. I`m keeping my eyes open for a new vice as I`m still not happy with my cheap, free with my mill, quick vice.

That is a nice vise. Nice job on the depth stop too! :beer:
The only thing I don't see the tightening handle.

That's a crackin' vice Stew! It's got all the whistles an bells...... :thumbup:

Mine? Ahhh......Well..... ::)
I've got two.......

No whistles, or bells. Just, spot on accuracy, now I have machined and properly reassembled the "big" one. :D
I keep promising myself, I will make a vice end stop, one day! It hasn't happened just yet...... (http://serve.mysmiley.net/rolleye/rolleye0012.gif) (http://www.mysmiley.net/free-mad-smileys.php)

StillDrilling - that is the vice I have and I`m still not happy with it. I need a tutorial.... I know you seem to have done a cracking job with yours. Do you not find it pushes the workpiece up when you clamp it to? - on mine, it pushes the workpiece against the back jaw and lifts the front edge up a touch!

Nice to see I'm not the only one with a couple of vices :D

The big knurled knob you can see in the first pic has a 3/8" hole through it for a tommy bar, you can't see this in the position its in.

Chris,
Don't you remember, we exchanged pm's re these vices? http://madmodder.net/index.php?topic=848.0
They "all" lift at the moving jaw! Even the expensive ones, with the diagonal screw....... ::)
The work always must be tapped down, onto parallels. :thumbup:
Stew,
Not too sure I want/ need to know that! :D

Yes yes, I totally remember John...It still rattles the screws loose and isn`t square. I need to look at your thread again and try again.

I splashed out on the 6" version of this not long after I bought my mill:
(http://i7.ebayimg.com/08/i/000/c8/2c/8294_1.JPG)
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=370424792603 (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=370424792603)
Mainly because the (much heavier) Abwood vice I got with the machine lifted the back of the workpiece by nearly 0.008" when clamped up - which I thought was pretty excessive. Then again, I've never used the Plastic Hammer of Dooooom to hammer work back onto the parallels - maybe I ought to do that?
Incidentally, the TiteLock vice pictured/linked above isn't perfect: It still lifts the back jaw when tightened, albeit only by about 0.001"; the biggest problem with it is the base isn't quite parallel to the top surface, and it needs a complex set of shims to get it dead level to the table... This was quite noticeable when I trimmed the block I'm making my QCTP out of: The mill behaved as if it was out of tram (ridges between cuts); actually, it's the vice that's out of tram... because I didn't bother shimming it (it'll be coming back off as soon as the BMW sump project is due back on, that simply doesn't fit in the vice...

Over the years I seem to have been slowly accumulating vices (some of which are handy for holding work too!).
I've a vertex which is pretty good for not lifting the jaws but the best one I've got is one of these:
http://www.arceurotrade.co.uk/Catalogue/Workholding/Machine-Vices (http://www.arceurotrade.co.uk/Catalogue/Workholding/Machine-Vices)
The screw is set at an angle so tightening them pulls the jaw down. They can be a bit fiddly so are not great for repetitive work but otherwise seem accurate and hold work well.

My new one lifts........

Maybe only a thou' or so, but it lifts.
I've never yet, met a machine vice that doesn't do that.....

I'll check mine tonight - never noticed any lift though. (Mind you I've never tried to measure any either)
