    Refilling Mk IXA Bubble Sextant
    From: Zvi Doron
    Date: 2004 Feb 25, 22:53 -0000

    Hello,
    Having found Steve Grobler's web page re restoration of the RAF Mk IX bubble
    sextant but having failed to communicate with him or with Robert Eno for a
    copy of the PDF instructions they have, hand written  by the Australian
    Frank Bartlett, could someone help?
    I know how to get to the bubble chamber, I know where the soldered bit is, I
    know I need Hexane and I know I need to use a syringe. I do not know what to
    do exactly and in what ordr, and in particular how much liquid should go in?
    How do I know that I have left enough air inside but not too much before
    resoldering?
    Thanks for any help or tips - the sextant otherwise is in great condition
    and I am really keen to get it working.
    Zvi
