Negative Positive
Title: poorly designed
Review: I found that when you tighten the wing nut it drives the adjustment thumb wheel into the surface of the table. There is only one bearing surface on the side opposite the thumb wheel. I put a shim under the adjuster where the screw goes through the mount. This kept the wheel off of the table allowing it to move smoothly. A real pain, but at least I can use it.Naturally this solution only works if the track is flush to the table surface (or you are using a wide track)
Is the review positive or negative?
