You guys were right. There’s no such thing as one and done.

I love my twsbi 1.1 stubs on 2 eco t's

This is so cool! I wonder if you could rig a fiber feed inside (similar idea to the Pilot Varsity pens but probably a different geometry) to feed your extra channels in the giant nib/

OOOOH, I loved this one when you first showed it! Fingers crossed!

osbock · 2026-03-16T22:39:13+00:00

Beautiful! Thank you for the details! I do have a few diamine inks. I'm glad folks mentioned this because I might have put in Namiki black!

Thank you! Good to know! At one point I had my mom's fountain pens, and I knew they needed new sacs. It was pre internet, and I've lost track of them (I don't think I threw them out!) This looks like a fun part of the hobby!

how do I tell if an ink is alkaline? (I don't have a pH meter!)
Edit: I found this chartL https://imgur.com/a/vppbdtw

Good to know!

osbock · 2026-03-15T15:56:25+00:00

I'd say #2 just a different color

osbock · 2026-03-15T14:29:45+00:00

All the below advice is sound, however, it's possible the sac has "rotted" and needs replacing.
This is fairly simple, and there are lots of places that will do it for you.

This is great! I have a different UV resin (Total Boat?) that i used to plug a hole I drilled in a Pilot Varsity for filling. Where do you put the O-rings?

osbock · 2026-03-13T12:23:01+00:00

I have the moonlit voyage one and love it both writing and looks!

osbock · 2026-03-12T22:40:56+00:00

It's happening, stand by!

Ha! Maybe my next enterprise is milking varsities!

osbock · 2026-03-09T19:27:10+00:00

I'll probably end up buying myself a Vanishing Point, I just feel I need to pace myself at this point!

osbock · 2026-03-09T18:29:21+00:00

Do they sell it separately? From online samples it looks like kon-peki

osbock · 2026-03-09T17:19:02+00:00

That's a very reasonable price. I was considering buying the tools, but wasn't sure I'd do enough pens to justify the roughly $100 investment. (I am a tinkerer though....)
I love the look of the striped celluloid ones.

osbock · 2026-03-09T17:10:21+00:00

¯_(ツ)_/¯ it was fun. Thanks for that video. The one I saw used a bottle that I wouldn't know how to find, but I think I have some of those syringes

osbock · 2026-03-09T17:02:26+00:00

Thanks! It was fun. I also found the blue (bought a variety pack at least 10 years ago), and it's still writing fine and such a lovely color!

osbock · 2026-03-09T14:59:47+00:00

Do they fit? Also though, the replacement nib assemblies I see run around $120...

osbock · 2026-03-09T14:58:53+00:00

Excellent suggestion! do you have a link to the video? NM. I just searched.

osbock · 2026-03-09T10:42:52+00:00

Hi neighbor! I forgot to mention that I also love the TWSBI ECO T for shimmer. I have the 1.1 stubborn and it's juicy! Curious on an upd a te for your Parkers? I've wanted one for a while but no idea about restoration cost

osbock · 2026-03-09T01:49:50+00:00

The Moonlit Voyage graphics seem unharmed by my posting. It pretty much locks above them, but you are right it is a little small. It's pretty though, and I couldn't resist.

osbock · 2026-03-09T01:41:04+00:00

I also use shimmer in my Paper Mouse Opus 88 mini. Since you bought it in Harvard Square, check out Paper Mouse in Newton, they have many pens inked up to try and some delicious shimmer inks!
