John, love the installments on your Planet Mesquite turning. I bet the problem solving is just as much fun as the turning. So as not to hijack you thread I wanted to ask about the bore sighter as an alignment tool. Looking on the net, I found three possibilities of shaft misalignment, radial, axial and angular. We know that just because the drive center point lines up with the live center point does not mean the lathe drive shaft is in alignment with the tail stock quill. Spinning the bore sight in the lathes morse taper, inscribes a small circle on the wall. The question is, is the center of that circle aligned with the drive shaft? My bore sight has the little adapter rings so as to get a tight fit in the morse taper, I can push/move the sight a bit to get a bigger circle, smaller circle or just a dot, the center of the circles and the dot are all in the same place. I know I don't need the accuracy, it's more a curiosity thing...
