I've been using this type of clamp for about 2 1/2 years now, started off with a clamp from HF, it will hold just fine for a long time, just learn how to adjust it. At my special tool store named Blade Runner in Wetumpka, AL, they had some there that are a little bigger, and the mechanism works a little differently but essinetially the same thing. The big thing I learned about how to set it up is to take a 2X4 and then recess the screw holes and screw a longer 1x whatever, I shape the 1X to something similar to a blade shape about an 1 to 2 inches wide, here is the big tip, bevel the sides the full length of the 1X, it will allow you to hand sand angles without getting into the wood. The 2X4 is perfect for clamping it in a bench vise! I can send pics later if anyone wants to see it. Great tip, I probably should have shared a while back!! REX
