How to polish the nib's inner tine. (text narration only, no voice over)

In this video, I'm going to demonstrate how to polish the inner tine when doing DIY nib smoothing. Polishing the inner tine is often overlooked, but an important final step in nib smoothing.
Disclaimer: do this at your own risk! I'm not responsible for any destroyed nib!
Step 1: Lift one of the tine slightly from the other tine to expose its inner side. Polish the inner side.
Step 2: Repeat Step 1 with the other tine.
Step 3: Align the nib
Step 4: Scribble some words or drawings to check for nib's smoothness. Repeat from Step 1 if necessary.

Brilliant presentation technique!

thanks~! Because I'm too shy to talk on camera so I just write and draw them all

[@Under_the_ink_fluence]

This is a brilliant video and lesson - well done!

You cannot imagine how much you've helped me rest, more than anything. As someone with high ocd I couldn't get it out of my head that, after smoothing, there was still a minor scratch from certain positions. I've destroyed nibs trying to get rid of that and no other video than yours mentions it. I did it 10 mins ago to a Conklin nib that I smoothed earlier this day and it turned it into a great writer. I've spent approx 4 hours on this nib today and your video helped me fix it in 2 mins, because it was the inner tines that was messing with everything. God bless you!

[@jacobonfountainpen]

Hey, I'm glad it worked out for you! The polishing of inner tine I think is quite under appreciated, more people in this hobby need to know about it.

Thanks!

[@zuperine]

Thanks, nice videos. May I suggest fixing the focus of your camera so that it doesn't hop between the notebook and your hand.

[@jacobonfountainpen]

Thanks for the suggestion! yup I only noticed this problem during editing.

[@llTheJVlusicInMell]

Your nib looked exactly how Richard Binder illustraded a perfect nib. I treated a baby's bottom today but was too afraid to remove more material. Not happy with the way it ended up. Still better than before... That was a throw away pen. I'm sligthly afraid of further ruining my Lamy F Nibs which are terrible to write with even aligned.
Edit: What Grid for the inner sides? Also, is the 2,000 sandpaper necessary ? (Regarding what's read on Richard Binder Guide)

[@jacobonfountainpen]

That's because I read from Richard Binder's note for nib smoothing! I've also ruined a nib before trying to smooth / polish a nib, until i removed so much material, the nib tipping is practically gone. Luckily it's only a jinhao steel nib.
I think for nib smoothing, the finer grid the better for the final stage of polishing, i often read about people using 12,000 grit lapping film or mylar or micromesh. Since it's hard for me to get those items cheaply at my area, i just use a nail buffing stick which I've no idea what the grit is. But it does give me acceptable results on jinhao nibs. Lots of trial and error.

Step 0: Remove red ink from pen so it doesn't look like you've wounded yourself doing this.
