Oggetto: [NavList 2895] Re: Plath kriegsmarine sextant servicing


 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.
