<p>Attempted to close CARME as carefully as possible.</p> <p>Swapped out one foot for another one and temporarily removed a second to allow CARME to rotate slightly and get a better alignment of the two surfaces of the COF600 flange.</p> <p> </p> <p>Closed CARME but realised carriages with struts are such that carriages touch before flanges do. Worse on side with leak than side without. See attached. As a result we would not be able to close properly.</p> <p> </p> <p>DR to modify the holes in the feet closest to flange on CARME front to allow surfaces to touch before carriages come in contact. Hopefully close later today.</p> <p> </p> <p>Issue was not encountered earlier because CARME was fully mounted before being dropped on feet. Struts were forcefully brought close to allow CARME to descend. Unclear how this was done in DL but may be baking had altered some sizes enough for the issue to appear. Spare feet do not help significantly.</p> <p> </p> <p>Closed CARME . 1. Bolts finger tight. 2. Bolts tightened with tools stopping as soon as resistance is felt. Tightening done from the top descending towards the right (clockwise) and from the bottom counterclockwise. 3. 20 Nm applied in the same way 3. 40 4. 60 5. 80 6 80 again but single operator going round 6. 100 single operator</p> <p> </p> <p>Pumping down overnight</p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p>
