Had an extra Jinhao x750 and a Zebra G nib (titanium) lying around, and saw the hype of the frankenpen you could make with these. Thought, "Hey, this seems easy, I could do that!" YouTube videos and tutorials spun a picture of ease and simplicity. And yet, seven hours (not exaggerating) of trying yielded no results - except for a stuck nib and feed. Heat setting had no effect on the stubborn feed, and pliers upon the nib to try and flatten it slightly resulted in much frustration when the nib failed to rest on the feed satisfactorily. I've read the forum pages and watched videos and done exactly as they said... yet, nothing. I'm at a loss of what to do. How do you do this ardous task so (seemingly) effortlessly?
