I have this Lamy Safari that I've been having ink-flow problems with. Following the example of some people on the forums I cut a piece from a plastic bottle and stuck it between the tines, but now they seem to be too far apart. The pen isn't totally unusuable or anything but it's just a bit wet, though I do have Noodler's Polar Black in it right now which seems to flow a bit too easily (as evidenced by nib creep). The space between the tines has made the line it writes a little bit thicker too.
I think I probably picked plastic that was too thick (milk jug) or maybe left it there too long or pushed it too far in. Anyway, it's not a super-expensive pen so I don't mind messing with it or further risking destruction of it if anyone has any ideas for me.
