DID you  clean the ink off the tip
before doing this ?



Hi Geoff,
 
    The BIC pens have tungsten carbide balls. If you  cut off the plastic ink 
holder, you can push out the 1 mm ball with a fine  drill / piano wire. You 
can then clean everything with methylated spirits and  reassemble it. The ball 
can be crimped or glued in position with two part  acrylic adhesive. 
 
    However, you can buy martensitic SS balls from _www.smallparts.com_ 
(http://www.smallparts.com)  They are  ferromagnetic.
 
    Regards,
 
    Chris Chapman
