I managed to convince myself to try out nib grinding, following the procedure (more or less) from this Ludwig Tan article. I used a cheap Jinhao 250 and some micromesh pads I got from Anderson pens. I should have done before and after shots, but I didn't. I started with the 1500 grit for large scale shaping and then moved to 3200 and 6000, smoothing on 12000 and mylar.
Pics of the nib, various angles, afterward:
And here's a sample of the line variation (Diamine Sapphire cart on Rhodia):
Any comments from those more experienced? It seems to write acceptably so far, but has a sort of dry-draggy feel, though not scratchy. I should learn more about smoothing/polishing perhaps?
Also anyone else who grinds their own, feel free to jump in and show off!
