I recently bought a couple of Lanbitou 3029s having read somewhere that the nibs could be swapped out for Lamy Z50 nibs. I wanted to use a piston-filler with a couple of broader nibs.
I'm no nib expert – this is my first nib project – but today I had a go. I slipped out the Lanbitou nib, which was easily accomplished, and slipped on a Lamy Z50 B nib.
It slipped on easily enough, but wobbled when it was in place. It seemed a little too wide to fit, though I couldn't see any real difference between the two nibs. I tried bending in the wings a little with my fingers. No result. I then used a pair of pliers and promptly ruined the nib, which bent along the centre line – the line between the tines – and had to throw it away.
Before I ruin any more nibs, can anyone advise me on how best to deal with this situation?
