So you mean you shaved off the actual thin outer finish off of the internal connecter, threads and all? So I imagine you had to remove it from the mod first, then Dremel it with some kind of wire brush end and then reconnecting it to the DNA250? Am I understanding this correctly? If there's a physical modification I can do to fix it that would be great! The 510 connector on mine is aluminum colour but is probably still anodized.
