    Bessey engineer gets an A from me

    OK, so this is billed as an "auto-adjust" clamp. What that comes down to is that you select the clamping force once and then you're done. A huge range of thicknesses is accommodated; thick to thin, all are squeezed with the same force. This is accomplished with a very clever and compact mechanism. I mounted it temporarily and passed it around the table at gents' coffee, and everyone admired it as much as I did as it grabbed any of a selection of sticks. Force is adjusted with easily accessible screw, but you might need a small wrench to work the jam nut if you want to secure it in a production situation. I like the two-parameter adjustment of the pad: distance from pivot and height. You can see this aspect in the catalog photos, though the auto-adjust mechanism is not visibly obvious. As an engineer I want to take it apart, but I shall resist the temptation. It's so solidly put together I'd bust it in the attempt. Buy one, try it, and you'll be back for more.

    Great product!

    I bought these to add to a horizontal router table I had set up for mortising. I was constantly going between different thicknesses of stock and resetting my old toggle clamps for each stock thickness was a pain. I was skeptical at first but these work exactly as advertised. They get moved from one jig to another and my old toggle clamps, which I have lots of, don't get used any more.
