[member=18240]Max Fracas[/member] By both ends, do you mean the locking lever on the scale, and then the knob on the front entry side of the fence? Or instead the front entry side knob and tgen the hex screw on the exit side of the fence? I always lock down the lever and the front entry knob, but follow the instructions in leaving the exit side screw loose. I remember seeing a review of the fence, I think from the Wood Whisperer, that mentioned it being an annoyance to have to lock the lever and the entry side knob, but I've never found it to be burdensome, and at this point it's muscle memory. I have on occasion forgotten to lock the front entry knob, but have never noticed it affecting the squareness of the fence -- but i continue to do so just to be sure.
