Hello Guys, you may or may not have heard about me, but i have been a member of this forum for long(different acc).

I have much enjoyed interactions and valuable information in this forum.

 

I am a fan of fountainpen writing. It began as a hobby back in my middle school years.

I started grinding nibs in high school. and small tweaks in university.

 

during my military service in South Korea, I designed fountain pens and machines required to make it.

after military service, I started making all the machines required to make fountain pens.

after two years of struggle, here i am.

 

i really admired small scale fountainpen craftsmen around the world, such as Nakaya, Namiki, Ranga, etc...

But I decided to take one step further...

 

I began with ebonite barrel, cap, grip parts.

I first began with Indian import ebonite material. but i had some issues with quality(contaminants, large pores, discoloration)

then i switched to Japanese ebonite supplyer. I am very satisfied with the quality of the material.

All my ebonite parts are made with Japanese import ebonite material.

In the course of 2 years, and hundreds of prototypes, I have literally perfected two types of designs:

1)v8.3 Symmetry

2)v8.2 Asymmetry

 

during this, i decided to make ebonite feeds as well, which is a real challenge (even for big manufacturers)

after painstaking work and research, I succeeded in making ebonite feed that functions like a plastic feed, although it is made from ebonite.

what i mean by that is, I machined ebonite feed, with a plastic feed design, which is very complex and difficult to do in ebonite.

internally, my ebonite feed has 5 turns of air / inkflow (compared to aurora ebonite feed, 1 turn)

this was done to make it more stable against overflow.

 

after that, i decided to make nib from scratch. no machines, no designs.

this was very difficult to do, with little resource and information.

but after painstaking work and research, I came up with my own manufacturing machines and process, that guarantees super high precision and quality.

 

at first, I started selling in South Korea, only.

but i wanted to share with the world, what i have created.

 

here are some of the pictures.

 

this is the nib, made from argentium silver 935.

it's got good flexibility, like a spring.

also, the slit is nearly always super high precision as can be seen below

fpn_1569993246__1.png

fpn_1569993264__3.png

 

fpn_1569993307__8.png

 

This is my home built ebonite feed (left), aurora ebonite feed (right)

you can see the 5 turns of ink/air flow, like a modern plastic feed (with ebonite feed)

it is very very intricately machined.

fpn_1569993213__0000.jpg

 

here are Two of my fountainpen designs:

 

Eureka V8.3 Symmetry

it shares 1 thread with both cap and barrel, to increase cap lip thickness(strong design) and reduce the bump between grip and barrel.

there is near 0 slop between threads, so very very high precision and high concentricity between parts.

the barrel will not unfasten when opening and closing the cap.

thread is double start

this pen can be used as eyedropper, without use of silicone grease. the seal happens before thread part.

fpn_1569993222__000.png

fpn_1569993316__9.png

 

 

 

V8.2 Asymmetry

this design is even bigger than 149.

the cap is postable very stably(matching angled taper fit)

thread tripple thread.

You can see my development process in my blog:

also, this is the link to my newly born store: (i will remove this if there is a problem, please let me know)

currently only available to US only (ebay doesn't allow me, as i am a new seller)

https://www.ebay.com...untainpen_store

 

Currenly, i am working on my website. will revise this when done!

 

 

this is a simple video review i made:

https://youtu.be/4KowdopVbHA

 

my email:

beatmaster90@naver.com

 

currently, i have mastered the technique of Perfect Urushi coating.

soon, i will be done with my cleanroom for urushi coating, and also sell products with urushi coating.

also, i am developing my own "!" shaped gold plated Clip. this may take a while.

 

thank you guys for your attention.

I hope I can deliver a new kind of products, at very reasonable price.

thank you!

thanks peroride :)

all my creations will be based on either symmetry or asymmetry.

additional machining may be done(ex. gathered, polygon, etc)

Those are very nice looking pens: congratulations!

 

How would you describe the feeling of the nibs? More like palladium than gold?

 

Also, is the nib made to a standard size (eg., like Jowo/Bock #6 or #8)?


Vintage. Cursive italic. Iron gall.

Wow! They look great! I am very impressed that you are able to do that. As soon as that red wood-grain Asymmetry goes on the market with an F nib, I will be your happy customer ;-)

the nib size is a little bit bigger than #6.

the feel, the best i can describe is, feels like a normal nib with little pressure.

with low pressure, the line variations occur very slightly.

with hard pressure (down stroke), the nib feels springly and line veriation 3~4 times regular thickness (but requires some force to achieve maximum thickness)

i have never used palladium nib, but my nib feels like something in between 14~18K gold nib.
