Lid up procedure Started at  12:00pm. Initial numbers. # 1-47,2-49,3-45,4-47,5-47,6-47,7-49,8-45,9-50,10-50,11-51,12-49. After a number of unsuccessful attempts at jogging the system and trouble shooting it was decided to suspend operations record numbers  and resume on Feb 2nd. Final numbers for Feb 1st #1-1289,2-1297,3-1288,4-1295,5-1283,6-1298,7-1287,8-1289,9-1290,10-1296,11-1287,12-1296.

 

Feb 2nd commence lid up operations at 11:30 am .When Maico Dalla Valle and my self arrived Dan Louie and Arther Leung had attempted to trouble shoot elevating issues and lowered the lid in hopes that raising would be smoother . The counter numbers on our arrival where as follows station   # 1-2856,2-2858,3-2848,4-2857,5-2855,6-2861,7-2856,8-2857,9-2852,10-2862,11-2860,12-2859. After Discussion between Grant Minor, Dan Louie and all involved it was decided to lower the lid re gap the yokes and reset counters to base numbers ensuring they correlated with master synchro. lowered lid numbers #1-55,2-59,3-55,4-57,5-57,6-54,7-50,8-54,9-59,10-59,11-58,12-59.

At this point we re gapped to .250" with counters at #1-119,2-177,3-123,4-144,5-137,6-120,7-123,8-111,9-127,10-148,11-128,12-117. After comparison with Dan L and the Master Synchro, stations #2,3,4,5,10 where jogged to better match the average on the counters and synchro these stations where put at 120 on the station counters. Once this was completed we started final lid up operations stopping at 5" to check tank seal, once it was confirmed the seal was not sticking we continued uninterrupted  to final lid up position. #1-16947,2-47366,3-47351,4-47365,5-47362,6-47365,7-17495,8-47358,9-47360,10-47366,11-47362,12-47363. Counters #1 #7 appear to be failing, they will be changed out and indexed to match as needed.
