17-Nov-04 A close-up of how the frame was 'indicated', which is to say we used a Dial Test Indicator which shows how far + or - 0.0005 (one-half of one-thousanths) the part is relative to another section. The 'front' of this frame, which actually the top when it is finished, is the reference from which all dimensions are made, and we discover that the holes already placed by another machinist are slightly off. We'll have to make some more adjustments to make things right....
