I bought a Pilot 78G with a BB (1.5mm flat stub) nib which writes well if I bear down on the nib, nothing extreme but heavy handed like with a ballpoint that doesn't write well. With no pressure it basically doesn't write at all.
I want to put document proof ink it for signatures but, I can't live with the pressure needed to get ink to flow. When I bear down it seems to write well at the speed I write so, I'm guessing the feed is adequate and the nib itself needs to be tweaked. The slit between the tines appears to be a bit too tight which is what I think is the problem. What do I do to increase ink flow to the tip without excessive writing pressure? Is this something a total novice can do without too much risk of screwing up the pen?
