Angus, Travis, Gerardo & Alastair Removed test mass from suspension and stored in tin. Small chip on the side of one of the ears on this mass due to brush against structure on removal. After TCS had replaced ring heater we put the production ETMY into the suspension ready for full alignment tomorrow morning. We checked the profile of the fibres in storage and the following ones all look to have approximately the same stretch. S1301759, S1301769, S1301770, S1301771, S1301772 & S1301767. The first 4 of these are now at at end-Y ready for use.
