So if you have not gotten a Rockler mailer, they will have their Jet parallel clamp kit on sale Friday after Thanksgiving through 11/30.
$119.99 for 2, 24" and 2, 31" clamps plus the blocks to hold them. This comes to about half price.
Anyway I may bite now that I have been informed that I could add softer pads to the faces. ;~)
On my current project I used my Cabinet Masters, Jet parallel clamps, and my Bessey Revo's.
I'm done with the Bessey Revo's, they are too crotchety, absolutely don't adjust as smoothly as the Cabinet Masters or the Jet's. AND their screw distance is short, I find myself using half the screw before they begin to tighten. I'll continue to use them but I probably will not buy any more. And while I'm ragging, their non adjustable foot on the end makes the clamps tough to use on surfaces shorter than the clamp.
