    Re: Instrument Engraved Marking Restoration - Help

    Frank,
     
    I recently had the problem of remarking the micrometer drum of a Husun 3 ring sextant from which all markings had been obliterated. I had excellent results in remarking by using a Rapidograph #0 drawing pen loaded with waterproof India Ink. The pen nib just fit the marking recesses and the ink flowed beautifully, doing a real professional looking job with no overflow or residual mess to clean up or polish off - don't see why the same procedure should not work in redoing the arc. In the past, I have also had good luck in redoing the markings on silver arcs and verniers by using a light solution of lampblack and oil - rubbing same on and lightly wiping off the excess. Good luck and,
     
    Regards,
     
    Henry

    I've recently acquired an old but rarely used Weems & Plath navigational proportional divider for my modest collection of navigational devices. The scales are lightly engraved and in some areas the black substance (pigment + filler) has been lost.  I hope some of you may suggest a suitable restoration material and hints regarding the best restoration method to use.  In advance, thanks for all help.
