I saw a clever plan once where the guy attached a square piece of steel to the bottom of the vise. The steel fits the table T slot precisely. He then lined the vise up and tightened the piece of steel in place. This way you can remove the vise and replace it ti the same alignment every time.

All Kurt vises are keyed on the bottom. They even sell the keys in different stepped widths IIRC. My import vises are also keyed the same (but included the keys and have to be ground down if you have something other than a bridgeport sized slot.) So maybe the guy wasn't so clever;) They do

All I can say... Is that I have had the cheap vices and tried to get one ground even to be flat and square. The reality tho is that if you really want to make parts and not screw around with things and waste time, the Kurt vises and some of the other top end vises are worth every single thin

Hi Stuart, true, but it's much easier to just verify that the alignment is correct than to align it without a key ;) Cheers, Philipp On 21.07.2014 18:44, Stuart Stevenson wrote: Gentlemen, my experience dictates DO NOT TRUST KEYS TO ALIGN VISES AND HOLDING FIXTURES!!! always verify the

Yup, I agree! if the keys were tight enough to get a few tenths alignment from end to end on the vise jaw, it would be hard to put the key into the slot. Also, my understanding of the way the slots are made in at least some machines is the slots are milled first, then the dovetails are cut (or
