I have an observation about cam clamps.
One of my students has been making some for himself. He bought a Shop Fox to take a pattern from. I pounded the roll pin out of the cam and found that the cam is drilled with the hole centered on the lengthwise centerline of the cam. This makes the cam reach maximum force when the cam is half way through its travel range. As you rotate past that point the cam gets looser. The Klemsias are drilled with the hole in the cam below (and a little forward, or outward) of that centerline. This little detail gives you more range of clamping pressure because the more you rotate the cam the more force you get out of the clamp, which is desirable.

[QUOTE=ToddStock] The Woodcraft clamps are pretty good, although other than a 10% sale, the price is merely tolerable. [/QUOTE]

I have a couple of those, and in my experience they are definitely not as good as Klemmsias. The cam will often come loose after they are clamped, whereas my Klemmsias never do that.

I really don't know what it is about the design of Klemmsias that makes them work so much better, but they've got it dialed in.
