Woody – Go for it. They aren’t the best, but will do the job. I have several of the aluminum bar clamps, and a dozen of so of the F clamps. Both styles have never let me down. The quick grip clamps however, are a different story. I’ve only bought a half dozen, but had a 100% fail rate. I buy Bessey when they are on sale, or if I have a gift card, or in the F clamp four pack (two 6" and two 12" for $19.99). But, I’m too cheap to buy them at normal price.
