Just picked up a Great Planes AccuPoint laser incidence meter. I have to admit it is an ingenious design and should be simple and easy to use...However...

I tried to zero this unit on a flat surface (by adjusting the angle of the weight and shifting the thumbscrew), while I can get it zero'd easy enough if I lift one end of the unit and set it back down, I am lucky if it is within a degree (more like 2 degress) of that zero point. Doesn't seem like the gimbal is very free. Sure doesn't return to the same point. Anybody else have this problem? How did you solve it? Kinda useless like this.
