    A-8A Bubble refill
    From: Eric van der Veen
    Date: 2012 Jan 22, 22:50 +0100

    Bill & others,
    Now with the averager jam solved (although not yet re-assembled), I have
    also unjammed the bubble assembly.
    Today I went out for a first trial with the A-8A, sun shot with natural
    horizon. Takes a bit getting used too, but not bad on first attempt.
    Now for preparing to refilling the bubble... I read some earlier posts
    on refilling, and apparently that was not easy on the A-8A. I am in the
    process of acquiring xylene and the hypdermic syringe & needle, but have
    a few questions meanwhile.
    * The manual says to remove lock screw and then the steel ball on the
    side. On my unit, I see the lock screw on top, and on the side is a very
    small screw (approx. 1.5 mm). So what is meant by the steel ball?
    * What is the small screw on the side?
    * How much xylene is needed (manual: 4.5 fillings of the lens chamber)
    * Others used the immersion technique. Is that more advisable?
    Thanks again!
