You should post on the fountain pens community on the wayfarers haven instance! I’m sure folks there would love to see this, and even more so once you get a result you’re happy with!
Wow, I swear I searched for fountain pen communities when I got on Lemmy but I must have only been searching locally. Thank you! I will certainly post it when it’s done.
I’ll give you a sneak peek at what I think the filling system will be. I thought I was going to make it a lever filler, but this is even easier.
This is a Jaxon Self-Filling #4, very similar to a Conklin Crescent Filler. Actually, I believe Jaxon was a Conklin subsidiary. It’s just a button connected to a big bar that squishes the sac, and a rotating slotted ring keeps you from accidentally pushing the button. https://i.imgur.com/KS5ldLl.jpeg
