Reinstalled ceramic insulators #6 7 8 to Q1 magnet by C Ballard. #6 and 8 went on with no issues. The copper tubing on insulator #7 had to be bent to
match the new position of the re-brazed #7 fitting. This may have been due to the removal of the inner and outer conductors (the two copper plates that
clamp the two coils together) during yesterdays repair which shifted the position of the coil. See photos.
