Overview: Somewhat unusually, the mirror is mounted onto a precision socket screw.

1) Gather parts for mounting the mirror on the voice coil bobbin. Clean the mirror mounting screw 90666A101_TYPE 316 SS LOW PROFILE SOCKET HEAD CAP SCREW with drop of methanol. Place small drop (30 ul) of lock-tight onto threads on the voice coil bobbin. Screw in screw, and leave overnight to set.

2) Glue remote focus mirror onto the screw using lens bond type EK-93 (takes overnight to set). Fill hole on top of screw with lens bond  and then mount mirror centered on the screw head (slight deviations from the center of the screw head are fine; a later alignment procedure will center the assembly on the beam). Make sure the mirror is firmly pressed against the screw and flat by pressing down on the mirror through some lens paper with a stick.
