    Re: Plath kriegsmarine sextant servicing
    From: Philip Lange

     From the photos I surmise that you have removed all the screws. Now it
    remains to remove the telescope. This will  allow the index arm to swing
    past the index and away from sextant body. Also remove the washer that
    remains on the index arm. This lifts (or pries -  careful!)  straight
    off.Then, with a soft object such as a small diameter dowel, tap the pivot
    from which you have already removed the one screw and covering washer . It
    is a tapered affair and the leads of the screw hole are easily damaged. Use
    extreme care or you will have a devil of a time getting it back together.
    When it is loose, gently lift the arm away from the body.
    
    Of course make sure that the body is supported and that the index arm will
    not fall out and distort the pivot when it comes loose. You should note
    that extreme care must be used to avoid leaving tool marks. Many of the
    components are of a soft metal.
    
    I rebuilt a Plath not so long ago and this was my experience.
