I went with the M12x0.8 triple lead. I bought the full set of taps dies. The housing taps and everything needed to turn a pen using either the size 5 or size 6 nibs. They were not cheap but they should last a lifetime if looked after. I have just purchased and received the brass threaded mandrels in 12x0.8 Lead and the M7.9 x0.6 with a M10x1 female thread from Phil all I need now is some shed time. A decent camera would help I don't post many pictures of my creations because the pictures are pap.
I am getting a steady stream of folk wanting pens but I will never get rich making pens. I received an email tonight from a Guy whose wife had bought him one of my fountain pens for Xmas. Apparently, he loves it. Made my day.
