SUBJECT: Telecon Pertaining to Mensuration Accuracy of Stereo Point
Transfer Device

,
indicated that there are two methods of bringing the Stereo Point
Transfer up to meeting measuring accuracy as set forth in the
specifications.
A. Shim Method
Shim both Y axes to half the existing error (Left is
20 microns and Right is 28 microns). Specification
maximum is 15 microns in 9 inches s would require
B. Correction Cam Method
This would cut the error one-half on all four axes by
employing a tilt nut type of an arrangement. This would
require about l2 weeks total time and cost or all
four axes.
2. wants either method done as a change in scope. They do
not intend to do this and absorb the cost laims that the
specifications require only their best effort and does not require
22 microns + .005% of distance traveled.
3. The information obtained from this change in scope would also
be applicable to future digitizing of the fiber optic viewers.
