JAC body assembly

[Betsy, Masayuki]

Assembly drawing: https://dcc.ligo.org/DocDB/0126/D1600270/006/D1600270-v6.PDF (Type-10)
    •    A #8 flat washer was installed between the body and the beam-blocking hole cover.
    •    Six strain relief PEEK blocks (D1700101) were installed.
    •    A heater cable (D2500337) was plugged into one of the heaters. The other heater is not yet connected, as we decided to complete the wiring after confirming its polarization.
    •    The JAC body assembly was weighed. Including these parts, the total weight was 17,781 g. This measurement includes the end covers (D1700031) with a total of four screws (two per cover). The end covers need to be weighed separately and subtracted to determine the actual body weight. (the weight will be summarized in the weight tab of the component list)
    •    Note that the screws used to fix the strain relief are not vented screws. These will need to be replaced once the correct vented screws are received.
