It was brought to our attention this afternoon, by Dr. McNulty, that we need to keep a separate work log to record who is stringing, clean-room temperatures, etc. We were tasked with creation of a new Excel file for this purpose and will transfer our existing records to this file tomorrow.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.
