The crew was split today. The dome work was completed by lunch time and the C-3 cover was replaced. Brushing in the chamber got started with 37 sections completed by the end of the day. Tool failures are running at about 50%. Four tools ran to the 1/2 hour mark and are ready for their first inspection ASAP. Four tools ran very slowly or for only short periods of time. We will retrieve chuck replacements from these and attach them to new drills and play the game again tomorrow.
