Each ledge has two M1 threaded holes. One is concentric with a 2mm |
| 145 |
|
diameter socket. |
| 146 |
|
The module features one precision pin on both short sides that fits |
| 147 |
< |
into the socket (Fig. \ref{fig:insets} c). |

|
The milling of the socket and the glueing of the |
| 149 |
|
ledge onto the shell are both done by using the same reference, i.e. the |
| 150 |
|
precisely machined ledge edges, so to ensure an accurate positioning. |

socket. At this stage only a rotation around the pin axis is possible. |
| 184 |
|
The mounting is completed by inserting in the corresponding precision |
| 185 |
|
socket the T-shaped aluminum pin placed in the U-shaped slot |

the hybrid. The module is finally tighetned by the four M1 screws by |

|
using a limited-torque screw driver. |
