I don't have easy access to a 12.5 mm drill bit for the cap of a JR Gent rollerball pen. The ½ inch drill bit that I do have is larger by about .0079". I normally use Gorilla glue to glue in my tubes, so there would be some expansion of the glue to fill the gap. Has anyone successfully used a ½ inch bit?
Thanks,
Wade
