Last night I checked my VSTA repeatability with the new angle-cube and found that my worst attempt put me within 0.10 degrees of my target angle. That particular VSTA has a little bit of skew to it when I tighten the screw. The other side hits much closer to target, with several attempts resulting in zero error. I’ll cut a couple of new screws to grind flush per my suggestion above – the current screws are eye-ball square.
