- On Friday package #1 was moved from 126 to Blue Crab and then package #2 - from Blue Crab to 126. After connecting #1 to Nitrogen it was found cell #5 is leaking; turned out the barb connector for the guage tube was loosely connected. These connectors are glued initially with super glue, but later on some of them (and not on this one) green epoxy was added. Casey was able to glue a new barb connector (not easy to reach the spacer ring since you have only 5mm between the cathode and the wire frame) and fixed the problem. Then green epoxy was added on all the connectors of packages #1 and #4 that didn't have it before (5 out of 12). Bill wants to try with Casey using shoe glue that better sticks to polyethylene. | - On Friday package #1 was moved from 126 to Blue Crab and then package #2 - from Blue Crab to 126.
