wedge measurement and magnets/standoff glueing on the input mirror

This morning I have dismounted the gluening jigs that we used to glue magnets and standoff on the end mirror 2 days ago. Magnets and standoff seem well attached but while trying to put the mirror inside its case a magnet came off. We reglued it just after cleaning the mirror. After few hours we removed the jig and let the glue cure without support (picure1)

We then proceeded measuring the wedge (pictures 2-3) and glueing the magnets on the input mirror (support number 4), following the same procedure reported here.

Few days ago we observed that on one of the stand-off we glued on the input mirror the glue seemed to have overfowded on the groove where the wire is supposed to stay (picture1). Today we made some tests with a wire of the same diameter of those used in the suspension and verified that it was the case. After trying to remove the excess of glue without good results, we decided that was safer to remove the stand-off and to glue a new one. (picture 2)
