I like the links Brian

It has me looking at the fountain pen a little differently.
Speaking for myself I find pen making fairly simple, and when problems arise they are solved quickly on this forum, simply by asking as someone on here has met the same problem before and will explain what is needed. Maybe I put that a bit simply but it does seem that way.
I made a couple of Omegas for the closed end competition, I entered the rollerball but I felt the fountain handled like a superior pen 
I can't explain this but I am finding this thread very interesting
