    Re: Artificial Horizon, K & E USN No. 6

    Thanks Paul:  The K&E magazine article and pictures describe/show  the
    device I have. On mine,the funnel top and its tip have been refined, and the
    pouring spout in my  basin has  further improvement.
    
    I previously said that the jug was rigidly attached to the bottom of the
    wood box.  I showed the entire outfit to a machinist last night and he could
    not believe that the jug was not removable. To explain, there are very
    unusual  screws  that go through the bottom of the box into the bottom of
    the jug (so I thought). My machinist friend put a wrench onto the jug, and
    with a tap on the wrench  the jug came loose. Ingeniously....the jug has an
    "internal" thread on its  recessed bottom.  There is a fine threaded plate
    (like on an old transit or level) that is actually attached to the bottom of
    the box. The jug screws onto the plate. Pretty neat and makes good sense.
    
    My machinist friend thinks the funnel top could be some special type of cast
    steel?  Its polished top, fine screws, and shape makes him question that it
    is cast iron. Who knows?  My research continues with all help greatly
    appreciated.
    
    Thanks again
    
    Bruce
