Hi James,
 
    It's just an idea, but I can still buy ink drawing  pens for technical 
drawing. They have plastic push on ink cartridges which can  be refilled and 
the ink is available in 250 ml and 23 ml bottles. The ones which  I am 
familiar with are UNO and Rotring. The Rotring Isograph nibs are available  
separately from 0.1 to 1.0 mm. 
    Note that you can also buy fine stainless steel  tube in a wide range 
of sizes. I use fine piano wire for cleaning blocked pens  with the special 
cleaning solution. Hot Fairy washing up liquid also breaks down  the ink 
quite well.
    Note that hot wires are usually spot welded on. I  would expect the 
wire to be Nichrome.
 
    Regards,
