Mounting Precision Vise
I got a hold of a one of those little precision vises that everybody is
selling these days. Problem is, there doesn't seem to be an easy way to mount and align it to my mill table. Neither can I find any clamps specifically for these vises in the usual catalogs (Enco, McMaster etc.) I suppose I could make something easy enough, but that got me wondering - as popular as these vises are, what is everybody else doing to mount them? My particular vise has slots cut into the base on either end, and a series of holes drilled crosswise down the base of each side. |

A hold down is just a flat plate to engage the slots on the side of the vise and a spacer block for the other end with a clamp bolt in the middle. You can also use hold them in a bigger vise for odd setups. I use a test indicator to align all my vises reguardless of size. |

Mounting Precision Vise
Thanks for the reply. "Troll", not sure what you mean by that,
anyway thanks for pointing out how to use a vise. Gees - would have never known. Allow me to be a little clearer. My question was, "What is everybody doing to clamp and align these little vices?" Thus far I have found no good answer. Strap clamps (toe clamp if you prefer) would work yes but there sloppy and don't lend them themselves to aligning, "squaring" the head very easily. I did find some drawings to make your own clamps at, "http://www.littlemachineshop.com/Projects/ViseClamps.php" but they seem, just by looking at them, not rigged enough, and wouldn't make alignment much easier then the strap clamps. I'm figuring now I will have to make my own clamps for each end. I'm thinking with some kind of eccentrics and set bolt for easy alignment, and perhaps a stop block for one side. I'm still hoping that someone out there has some really slick better idea on what they did and would be willing to share it. |

When mounting a vice to a machine, it is almost always necessary to indicate the vice in straight if you want accuracy. |

Mounting Precision Vise
The alternative to the "precision" vise you refer to is to spend the bucks
for a standard mill vise, which come with slots in the bottom in which you can place keys to match the slots in your milling machine table, and also have the standard slotted bolt flanges to clamp to the table. Good luck! "Dave Lyon" wrote in message news:2qSBf.731502$_o.314376@attbi_s71... wrote in message oups.com... Thanks for the reply.

Mounting Precision Vise
According to :
I got a hold of a one of those little precision vises that everybody is selling these days. Problem is, there doesn't seem to be an easy way to mount and align it to my mill table. Neither can I find any clamps specifically for these vises in the usual catalogs (Enco, McMaster etc.) I suppose I could make something easy enough, but that got me wondering - as popular as these vises are, what is everybody else doing to mount them? My particular vise has slots cut into the base on either end, and a series of holes drilled crosswise down the base of each side. Well ... I made clamping plates for mine to match the Emco C5 mill and the toolmaker's vise which I got to use as a milling vise. Here is the URL to a page which I put up to document that when I made it. The dates seem to be in September of 2000, FWIW. http://www.d-and-d.com/EMCO/Vise-and-clamps/index.html Note that mine does not have the series of holes, which might work with the round-nose clamping straps supplied with mill hold-down kits. Or the holes may be part of the draw-in mechanism for the so-called "screwless" toolmaker's vises, in which case you would want to confine your clamping to the grooves similar to what I used.

for a standard mill vise, which come with slots in the bottom in
which you can place keys to match the slots in your milling machine table, and also have the standard How accurate is this method? I would be concerned how accurate the T slots are with respect to the direction of travel. |

Mounting Precision Vise
All I can tell you is from my experience 'many' years ago when I was
constantly changing between vise jobs, rotary tables, etc. I machined a couple of keys to match the table slots, indicated the vise, and thereafter it always was within .001 inch over the six inch length of the vise jaws. The machine was in excellent condition as was the vise. Keep in mind that care was taken each setup to keep the keys against the same edge of the slot and to tighten holddown bolts slowly and evenly. Good luck! Other machines could possibly yield better/worse results??
