    Hey, you should know the forum rules.

    NO PHOTO, NO BRAG!

These also work well on a surface plate where you need to align pieces. You can set the vises on 3 sides- the jaws are flush to the sides, so they can be set with jaws vertical, and in mirror image fashion.

    One of my more useful projects- and one which I completed.

    I have two vises on my BP. The first won was from Parlec, the second was the premium vise from Shars. Both are 6". The bed heights are identical. I needed a .007" shim behind the the fixed jaw on the Shars to get the fixed jaws to line up. I also have a Shars 6" CNC type vise I use when I need to hold parts "on end".

    This. Much more important than an extra vise.

    I have a pair of 100mm Bisons which can be used as a pair spaced out for long jobs, a Chinese 5" Kurt clone which opens 50% further than the 100's and several smaller vises for the tiny jobs. The 5" is pretty much at the size limit of the two mills at the museum.

    Two vices are always better than one...

    Good point on the DRO and that’s definitely on the list as well but will be easily funded by the sale of the PM-30MV.

    I have two (matched) 5" Gerardi Vices on my CNC, and a single 6" Vice on the Bridgeport, both are perfect for what I use them for.
    The Vice comes off the Bridgeport more so than the CNC as I frequently want all the table space, whereas on the CNC all the jobs have to fit within that working envelope.

    I absolutely agree. Without a DRO a mill is only half a machine...

    About two years ago I went through a similar process. I finally decided to purchase a milling machine vise for my Grizzly mill. In the past at work I have had to work on longer parts, like front panels for rack mounted equipment. These front panels are a standard 19" width and while they could be mounted with spacers and standard tee slot clamps, It was a lot faster to mount them in a vise. But no single vise would cover that size. For those panels I used three matched vises. In my home shop I wanted at least part of this capability.

    But, since most of the parts that I will ever make are smaller, I also wanted to have the largest work envelope that my mill was capable of handling. My mill has a fair sized table and on overall envelope of 7 7/8" x 21 5/8" but I realized that the position of a vise on the table would influence just how large of a work envelope I could actually use in that vise. I went through a process that included a discussion here and some experiments using full size, cardboard cutouts of the milling vises that I was considering. One thing that I found out was that, a six inch milling vise when mounted at one of my table's slots had a smaller Y axis available space than a five inch vise would have. I based these cutouts on the Shars line of vises but many imported vises are almost exactly the same. Here is a link to that discussion.

    I strongly recommend that you carefully consider the size of the vise you purchase. Most mills have limited Y travel and the column behind the table further limits things. Then there is the fixed location of the slots in the table so you can not always mount the vise where it can best use the available travel. A smaller vise can have a larger work envelope. And as for the width, I find that the difference between a 5" and a 6" is almost no difference at all. I may make a set of 6" jaws for my 5" vise some day, but then, perhaps not.

    As for the one or two vise question, I found that Shar's prices along with an available discount, made the choice of two vises an easy one. I did think long and hard about getting a swivel base. Many will say that they have one and never use it. Probably so. But if you need it, it would be very handy. So I purchased one vise with the swivel mount and one without. This worked well as the two vises are identical.

    As for the quality of the Shars milling vises, I have no complaints. Perhaps Kurt's are better. For the price, they should be. But the Shars are as accurate as I will ever need.

    If the money right now isn't a big deal, then yeah, spring for a pair. Having 2 that are matched is very handy for long stuff. Or even 1st op/2nd op setups. One with talon grips, and the other with soft jaws/hard jaws for the 2nd op.

    I don't know anyone that would say they wish they only had one vise.

    I currently only have a 6”’on my mill at home.

    Last place I worked had 2 “ mounted to the tables. For the work that they were doing they worked out well.

    Current place had a single 8” mounted. The 8” worked well for most of the work they I was doing with it. A single 6” would have probably been small and 2 would have been better. Down side of the 8” was the weight.

    With that said, if you don’t plan on leaving a vise and rotary table mounted at the same time and funds aren’t the issue just get the 2 and be done with it. At no time are you ever going to say “I wish I only had one vise”. There may be a time where you were wishing for 2 though.
