Core Lab
ThermCon
Thermal conductivity had intermitted readings. At first it was thought that the pucks were faulty, but after the instrument was opened we found the ribbon cable not seated properly. Reseated cable and unit worked well.
Splitting Room
Replaced 2 front shaft bearings on the Parallel Rock saw that was making alot of noise. Ordered 4 new ones for spares.
Repaired a stepped off wire at the base of one of the yellow transducer pads, and made the connection more robust.
