Travis, Angus and Alastair contued with the weld practice at end Y. Travis welded in all 4 practice fibres on the test set up and hung the dummy mass. We re-arranged the weld trolley and fibre preparation table positions to allow line of sight for Doug's alignment tooling during the welding. All tooling is functioning as expected. Tomorrow first thing we will remove the "old" ETM from the structure to allow TCS to work on the ring heater and then pop in the "new" ETM in the afternoon and do full alignment of the masses in preparation for welding again on Thursday
