CASIC says the flatness of its test track is within an 0.3 mm (0.01 inch) tolerance, that the 6 m (20 ft) diameter vacuum tubes have a geometric size error less than 2 mm (0.1 in)
The tolerances for the tube itself in most parts is not the issue. The tolerances at the points most likely to leak are the real issue. I guess we’ll see.
