Editor's Review: Clamps in the Woodshop

by Tom Begnal

review date: December 1, 2008

Bessey tools has improved its K Body parallel clamp. The K Body Revo has some advantages over the original. For starters, each jaw has the same great parallel action, but 30% more surface area. A larger, softgrip handle adds comfort and makes it easier to add extra clamping force. Bessey claims the K Body Revo gets you 1,500 lb. of clamping pressure, 30% more than its old model. When we measured the Revo clamp force using three woodworkers as testers, we got a maximum force of 1,000 lb., with 800 lb. as an average-still a lot more than the 600 lb. we got from the original.

The K Body Revo includes a plastic end piece that keeps the bar from tipping when the jaws are working close together.

The piece is removable, allowing the jaw to be removed and reversed, turning the clamp into a spreader. In use, the sliding jaw moved smoothly along the bar in both directions.
The jaw gripped the workpiece as soon as I began turning the handle-no fiddling to get it to "bite" into the bar.

The Revo is sold in eight lengths, from 12 in. to 98 in. ranging from $36 to $72 in price. Look for more information at www.besseytools.com.

Much better than the original K-body design. I happily sold my entire rack of K-bodies and upgraded to Revo's. The handle was the biggest factor for me. I have large hands and the increased diameter is much nicer, plus the non-slip material relieves hand strain. I no longer have to use a death-grip to get it to turn.

I was skeptical when I first received these clamps. They seemed to be to light weight for the kind of work I intended for them. I was pleasantly surprised by the rugged construction. Well done.

I have been using the new Bessey KR Revo for about year now and have them from 12" (30cm) up to the monster 98" (250cm) 40 in total. I have used many different styles and manufacturers of parallel clamps over the years, but I have never before, found a clamp come close to that of the KR Revo, the positive action and precise parallelness of German engineering. I am just about to order some more 12", 24" 50", these seem to get the most use and we are always fighting in the workshop to get these sizes. These clamps have improved our productivity quite a bit so well worth the extra dollars, they will last a life time

I have both the new Jet and Bessey K body Revo Clamps.Both are very well made,and clamp efficiently, although in use the Besseys are easier to adjust along the bar. The Jet clamps don't move as freely and smoothly as the Besseys And you do have to lightly sand the faces of the new Jet clamps so they won't mar your work. If I were paying retail I'd spend the few extra dollars for the Besseys. Having bought the Jet clamps on sale as a set cost me about half what the Besseys cost which made them well worth the little extra effort to adjust and fine tune.

I recently bought 4 of the 31" and 4, 50" clamps. I'm very happy with the ease of use and the clamping strength. On the first application, however, one of them slid off the side of my bench and fell to the floor. One of the plastic covers shattered and is no longer usable. That said, I'd buy them again and will probably get more of the smaller versions.

I have used the 12 inch size. They are the best clamps in my shop. I plan to purchase larger sizes in the near future. Gabriel
