    Re: Ball Recording Sextant Mark 1 Mod. 0
    From: Rob M

    something which may be of interest to other Ball Sextant owners: four
    different recipes for Typewriter ink, which may be useful to re-ink
    the "carbon pad" of a ball sextant. (oddly enough, my local chandlery
    was out of fresh replacement carbon pads, and my stationery store
    doesn't stock the ink anymore . . . what is the world coming to?). I
    am not sure which one is likely to offer the most success, anyone have
    an opinion?
    
    From the "Henley's Twentieth Century Formulas, Recipes & Processes"
    encyclopedia, by Norman W. Henley et al (1916).
    
    Typewriter Ribbon Inks
    
    I
    
    Take vaseline (petrolatum) of high boiling point, melt it on a water
    bath or slow fire, and incorporate by constant stirring as much lamp
    or powdered drop black as it will take up without becoming granular.
    If the vaseline remains in excess, the print is liable to have a
    greasy outline; if the color is in excess, the print will not be
    clear. Remove the mixture from the fire, and while it is cooling mix
    equal parts of petroleum, benzine, and rectified oil of turpentine, in
    which dissolve the fatty ink, introduced in small portions, by
    constant agitation. The volatile solvents should be in such quantity
    that the fluid ink is of the consistence of fresh oil paint. One
    secret of success lies in the proper application of the ink to the
    ribbon. Wind the ribbon on a piece of cardboard, spread on a table
    several layers of newspaper, then unwind the ribbon in such lengths as
    may be most convenient, and lay it flat on the paper. Apply the ink,
    after agitation, by means of a soft brush, and rub it well into the
    interstices of the ribbon with a toothbrush. Hardly any ink should
    remain visible on the surface. For colored inks use Prussian blue, red
    lead, etc., and especially the aniline colors.

    Aniline black...... 1/2 ounce
    Pure alcohol....... 15 ounces
    Concentrated glycerine ............. 15 ounces
    
    Dissolve the aniline black in the alcohol, and add the glycerine. Ink
    as before. The aniline inks containing glycerine are copying inks.
    
    III
    
    Alcohol......... . 2 ounces
    Aniline color....... 1/4 ounce
    Water............. 2 ounces
    Glycerine......... 4 ounces
    
    Dissolve the aniline in the alcohol and add the water and
    glycerine.               _
    
    IV
    
    Castor oil.......... 2 ounces
    Cassia oil.......... 1/2 ounce
    Carbolic acid....... 1/2 ounce
    
    Warm them together and add 1 ounce of aniline color. Indelible
    typewriter inks may be made by using lampblack in place of the
    aniline, mixing it with soft petrolatum and dissolving the cooled mass
    in a mixture of equal parts of benzine and turpentine.
