Fig. 2-91 Calibration ball meshing method
The lengths between the knots should be 1/4 of the circumference of
the calibration ball. (About 3cm because the diameter of the calibration
ball is 38.1mm.)
For how to make a knot, see the upper left figure.
The attached synthetic fiber threads should be used for the calibration.
