      I am having problems in getting work to sit down squarely in my nominal 3” Jaw Abwood machine vise, the problem being exacerbated by the relatively small seating width of 1.75”.  Given that this an old but reputably good make of machine vice I am surprised that the seating area should not have been made bigger to maximisAbwood Vice (2)Abwood Vice (1)e the chances of ensuring squareness. Has anyone else had this problem?

      To avoid further frustrations I am thinking of splashing out and replacing it with a more modern alternative having a similar overall size. Can anyone suggest some possible options within a reasonable budget?

        I can’t see why there should be a problem.   What sort of work and what is your procedure?

          i am using a standard range of parallels and where necessary, the wavy variety and then tapping down in the recommended fashion but given the short seating area it is all too easy to get things out of square.

            Hello Greensands,

            Have a look at the ARC “versatile” milling vices.  Very pleased with my 100mm version.  Pity I had to buy it with a swivel base (removable) that I’m unlikely to use in the future.

              The design of the dovetails and gibs in the moving jaw does tend to make the central section rather narrow. What about a pair of blocks with cutouts where the vise clamps intrude, each held down to the bed and milled to match the height of the base of the vise? They would have limited fore and aft width, but could be made so that they were capable of being repositioned for larger work.

              The ARC versatile vise is quite good, I bought a 5″ one for its much greater opening, you would benifit from a 4″ model. The downside is they gobble up every bit of swarf which the Abwood will not, but I have been glad to have the swivel base at times, it is easily detachable to store most of the time. ARC also sell a range of superior vises.

                First we need to understand the issue.

                If the OP means two sides square, ie, perpendicular, then the base of the vice is irrelvant. Squareness is set by the relationship between the fixed jaw and the machine axes. If, however, the OP means two opposite sides parallel then the vice base does indeed have an effect.

                I have a large (by ME standards) high end industrial machine vice. The width of the ways is about 6″ but it is still hit and miss to get two sides parallel to a thou or so. If I really need parallel sides then I prefer to clamp the work direct to the milling machine table.

                My original machine vice looks very similar to that shown by the OP, but has no name and is much larger. It had nearly 20 thou of jaw lift, which made life un-necessarily complicated. Which is one reason I bought the aforementioned high end machine vice.

                Personally I wouldn’t give workshop room to wavy parallels.

                  I think I could be tempted with that ARC Versatile vise which looks as if it might solve all my problems.

                    My preference and suggestion would be for the Arc Precision vice over the versatile.

                      Would that be the Type 1 or Type 2 precision vise?

                          I had & still have a Abwood 4″ vice. I was not happy with the narrow jaw opening area. From memory about 3 1/2″ I purchased one of the ARC 4″ iron ones , this has a huge jaw gap. From memory around 5″. I did a full revue on my youtube channel. Very happy with it after around 2 years of use. ARC Versatile SG Iron Milling Vice. No swivel. They have the no lift moving jaw. The Abwood is a far superior vise but just too small for most jobs.

                              The Versatile and iron versions although having the wider ways which make them better for supporting a parallel or longer work do have the disadvantage when working on shorter parts of not having any support in the middle so you can’t stand work on the bottom and have to raise it up meaning more stick out and less to grip. Six of one half a dozen of the other. But I still prefer the Versatile over a precision type.

                              I do use wavy parallels but only on work that is thinner than one of my usual solid parallels so the jaws can be close up onto the work. Otherwise it is one or two solid parallels.

                                Did you try (a Type 3) precision vice to arrive at that preference Jason?

                                The choice of vice for every person depends on a multiplicity of factors, but based on the fact that this forum is aimed at mostly home workshop and modelling its does sort of define the probable physical size of suitable vices to, say, between 50mm and 100mm jaw width. Low profile is generally important too.

                                For me the best feature of the Type 3 is the total lack of jaw lift combined with the fact that every external surface is a precision reference. Setting parts in the jaws is highly repeatable.

                                Slight qualification to the jaw lift statement. My vice did not come from Arc (but it looks identical) and after 10 years of hard use I cannot detect ANY play in the moving jaw, however Arc’s description states,

                                “The moveable jaw is held down with a keep plate and two screws. The screws are not locked tight but are used to adjust out jaw lift”

                                I wonder if this is an error and the screws can be locked tight? (I have sent a message to ask Arc).

                                  It is based on having two type 2 vices. They seldom get used only coming out for the odd job where they offer something over the two Versatile and one K4 such as the 90mm wide ones taller jaw height which can be useful when gripping a large dia that may have it’s mid point above the top of the other vices jaws.

                                  I posted this some time ago, comparing jaw lift

                                  vice lift

                                  The Versatile is also lower than the Type 2 so a bit more head room to play with. You can also see that the base width is larger on the versatile than the type 2, though I think the type 3 is full width?

                                    I think in my situation it would be a case of hanging on to the Abwood to take advantage of the solid centre base section for use with relatively short lengths of work and then to consider an ARC type Versatile/Precision vise for holding longer lengths extending beyond the jaw width.

                                      The Abwood is a quality took – have you adjusted the gib strip?  It is not the easiest job as there are TWO grubscrews per hole, the upper one being to lock the lower one.  So you have to remove the outer, adjust the inner, replace and nip the outer and hope the fit is what you were aiming for.  Repeat as required…….

                                      Once nicely set it will last a long time.

                                        Greensands, years ago I lusted after an Abwood vice and bought a 3″ the same size as yours, it was a lovely tool and I had no real problem with the short centre section but the limited jaw opening was very very frustrating! I ‘upgraded’ to a 4″ Arc versatile vice [blue painted as Jason B photo above], not the best quality and I had to get the 2 hard jaws surface ground from new as they were tapered but I love it, some much capacity!!!

                                          You could always machine a step in each jaw, maybe 3mm wide and deep, and grip thinner work that way, with no need to use  any support. I do this with all my vices, and when the steps get a bit worn, I re-machine the step, or make new jaws. Very handy if you are doing thin work. Just clock the vice  up, and make sure it is really true, tighten the jaws, then run a 6mm or a 1/4″ endmill through, centred on the joint, and the depth you need.

                                            The ARC versatile 5″, 125mm which I bought has had the rear flange cut off to give a bit more Y movement on the mills. When I bought it, I might have gone for the better SG iron ones, but the smaller didn’t open far enough and the larger was really too big to fit comfortably on the mill bed, which is the largest bed fitted on a round column mill with 500mm X axis movement.

                                              Jaw lift does not matter if you use a pull-down. They are a bit tricky to set up, but very useful.

                                              Anyone has a 4″ Abwood vice in good condition that they don’t want, I can give it a good home!

                                                If you are really concerned about max jaw opening how about a two piece?, your parts would mostly be on the table as well (more headroom).

                                                  I have a machine vice that looks identical to that posted by the OP except that it is not marked Abwood. I never use it now so if anyone is interested let me know. Jaw width is a tad over 6″, so for the larger milling machine.

                                                    For overhang of long components being machined I always use a pair of parallels out board of the vice, and tap down over the parallels! But one of the essentials with a vice is to ‘service’ it to minimise the jaw wobble and lift, check thos gib strips and adjust them with the screw removed to get the moving jaw to slide smoothly with minimum binding. One of my vices is a 4″ Abwood and I always get work seated with the minimum amount of faffing. I always clean it scrupulously on the underside as well as the mill bed (after occasional using a ‘flatting stone’ on the table) before clamping it down. Then I run a 1/10 thou clock to align the fixed jaw and also run it across the bed of the vice to check parallelism to the table.

                                                    A trick I learnt as an apprentice was to use a sheet of folded newspaper trapped between the moving jaw and the component being gripped, this was an aid to preventing the job ‘bouncing up’ when tapped down. For a tapping hammer I also always use a lead hammer. The ‘tap’ needs to be just that, not a blow.

                                                    As for vices I seem to have collected a variety over the years, these include a 4″ Abwood (as previously stated), a 4″ Edgwick (identical to the Abwood), a 4″ Palmgren (USA made), a 4″ Aciera on a swivel base, another 4″ Abwood on a swivel and tilt base (a brilliant vice for some jobs but with a resultant reduction in headroom). I also have some 3″ vices, which are of unknown origins but are likely to be British or at least European – one possibly a Schuablin. All are likely to be 50+ years old but where necessary they have been reconditioned to clean up ways and new jaws fitted, bases skimmed if any dings were present, drill holes filled with Metalux Cold casting iron epoxy (to the extent that they are visually perfect!). Part of the fun of machining is getting to know the quirks of your tools and finding the best ways to correct any known problems.

                                                    If I had to choose any of my vices as a keeper then it would probably be the Abwood or the Edgwick (which I picked up at a junk shop for £15 in a very sorry state – but it did come with the original handle), closely followed by the Aciera which is beautifully made and is really ‘low slung’.

                                                      I have often wondered how the mechanics of ‘tapping down’ works. I presume its main purpose is to settle the workpiece down, maybe by squashing any trapped dirt or flattening any surface burrs. If everything was clean and touching surfaces flat then tapping down would not do anything (although it might give the operator a nice feeling).

                                                      I wonder if there is an online thesis on tapping down!

                                                      My goto milling vise is a ‘Precision Type 3’ (not an Arc one but it looks identical). I understand these vices are intended for use on surface grinders and for toolroom use, I have also seen reference to them used for metrology purposes as they are machined (ground) on all surfaces to quite high standards of parallelism and squareness.

                                                      Mine, after 10 years use shows no detectable play in the moving jaw (hard ground surfaces sliding on hard ground surfaces), the jaw faces are parallel to each other and perpendicular to the vice base and since it exhibits no ‘jaw lift’ I cannot see any point in tapping down so I don’t bother.
