Platinum-Silver Nib, First One Made, Through Research And Study. IT's been a while since, i began using platinum material to fortify the sterling/argentium nibs. it's been quite a journey, but still not finished yet. today, i created my first platinum silver nib, an improvement from argentium silver nib. it has superior scratch resistance and tarnish resistance in terms of tarnish resistance, argentium silver did better job than sterling, but still not satisf.. 2020. 8. 4.
Dangers of working with Uncured Urushi ! Urushi is one of the strongest allergy inducing material. working with urushi always has the potential to cause this allergy. Urushi allergy will last 15~30+ days, and that's under good care. only liquid state urushi is poisonous, dried state, not so. not so sure about sanded urushi from dried state. from what i've heard, sanded urushi from dried state is almost non-poisonous, if it is very old... 2020. 7. 29.
New Silver Alloy Developed (AuAg) New silver alloy has been developed as an alternative to PtAg alloy. It is possible to make PtAg alloy based nib. however, through personal research it has been revealed, that the addition of platinum increases brittleness of the entire alloy. due to this nature, for every 10 nibs produced, half of them failed do to cracking, during manufacturing process. the rest lucky ones did not exhibit any .. 2020. 6. 16.
Platinum Silver Alloy has been developed, for nib material Progress in nib material research! Platinum Silver alloy has been developed, as an improvement over Argentium silver. this material is superior than Argentium silver, in all aspects. theoretical advantages... 1. scratch resistance; much harder material than argentium silver 2. tarnish resistance; far beyond argentium's tarnish resistance 3. superior flexibility and memory ◆Eurekafp.com ◆Email: b.. 2020. 6. 10.

Platinum Gathered installed on Gold Deco Tamenuri (GDT) barrel and cap (+prototype urushi walnut pen rest) this is the urushi walnut pen rest, after 2 coats of urushi. gold deco tamenuri will be done on this as well, as a prototype. Gold deco tamenuri is finally done for the platinum gathered! what started as a prototype actually turned out quite nicely! ◆Eurekafp.com ◆Email: beatmaster90@naver.com ◆Instagram: MechGyver_Eureka ◆twitter.com/PenEureka ◆youtube.com/c/MechGyver ◆fountainpennetwork.com/fo.. 2020. 6. 1.
gold tamenuri on different colors! gold tamenuri on different colors! (cyan, dark red, beige) on top of this, regular urushi will be applied, so its final result will be of different color! obviously needs more gold on this, but shown as example B&C for century and gathered is almost ready! 2020. 5. 31.

Gold(24K) decoration technique acquired Tamenuri + gold decoration brighter gold colors need urushi coating on them, haven't done yet. darker gold colors are the ones with urushi coating on top, needs a few more coating. this requires high concentration, and patience...

eureka clip V2, designed OVERALL DESIGN: EUREKA! / THE EXCLAMATION POINT. will continue to modify the clip design, for best function and production capacity. it's a spring loaded mechanical clip, like lamy. it requires precision parts, not pressed/welded parts. will need to move my factory before i can start working on it, which will take 1~2 years. v2.1 MODIFIED MORE STREAMLINED, LESS BOXY ◆Eurekafp.com ◆Email: beatmas.. 2020. 4. 18.

Harder type of argentium nib developed. Previous types were softer, due to finer frontal nib shape. this type, the nib is firmer. I am expecting this design will be even more durable than previous version. ◆Eurekafp.com ◆Email: beatmaster90@naver.com ◆Instagram: MechGyver_Eureka ◆twitter.com/PenEureka ◆youtube.com/c/MechGyver ◆fountainpennetwork.com/forum/user/147641-the-fountainpen-researcher/ ◆blog.naver.com/beatmaster90 ◆facebook.c.. 2020. 3. 23.
Ebonite Feed 3G V7 The best ebonite feed I've designed! compared to previous version, -stable and a bit juicy ink flow. -Ink spurt resistant -improved ink suction from heart hole -stronger inner combs (thicker) this feed will be used from now on (for the pens on sale) ◆Eurekafp.com ◆Email: beatmaster90@naver.com ◆Instagram: MechGyver_Eureka ◆twitter.com/PenEureka ◆youtube.com/c/MechGyver ◆fountainpennetwork.com/fo.. 2020. 3. 13.
ebonite feed 3g v6 so far, there has been a total of 4 reported cases of feed problems, of all pens sold. 1st gen: 1 overflow issue (fixed) 3rd gen: 3 cases of low flow issue (when continuous heavy writing), one of these 3 cases also had feed & nib fitting issue to tackle this problem, the ink slit has been increased from single to double. this enables continuous stable flow, and does not overflow. to deal with th.. 2019. 12. 12.

Prototype Nib #9 (9/1/2019) Material: 14K Gold Basically same as #8, minus the material Mass production, not possible at the moment. hopely, I might be able to achieve some degree of production. in terms of writing function, the gold one is a bit stiffer than the argentium counterpart. also, more tarnish resistant. otherwise, similar in terms of function.

Ebonite Feed 3rd. Gen V4.0, V5.0 Upgrade list 1) Differentiated comb thickness at front section (front side thicker then rear ones) 2) 5 turns of air/ink path (Aurora ebonite feed 1 turn), stability increased. 3) micro slitting across the front part added, to inprove function and stability 4) tail thickness significantly increased to improve durability 5) feed overall thickness increased *below is the lastest version: 3G V5.0, .. 2019. 10. 5.
Ebonite Feed 3rd Gen. V2.0 (3/13/2019) modification to the previous version... 1) internal comb is thicker than external, therfore preventing brekage 0.6mm -> 1.2mm tested 10 times in and out. no breaking. 2) Slit thickness reduced in order to increase ink holding capacity. comb number increased to 30. 3) frontal combs added to further increase ink holding capacity. 4) front part sharper angle 2019. 10. 5.
Analyzing Problem with 3rd Gen. Enonite feed (3/12/2019) 1) some fins break, when insertion and removal is repeated. this is a mojor problem, becuase some advanced users will inevitably remove the nib and feed. the underchannel + under fin structure design weakens certain portion of the feed significantly. even though the combs are 0.6mm thick to compensate for loss of structural integrity of the design, it simply isn't going to work. 2) the "tail" po.. 2019. 10. 5.
Ebonite Feed 2nd Gen. design (1/8/2019) The air channel has been moved to bottom, like that of the old version platinum gathered ebonite feed. these days, literally nobody makes feeds like this. the air channel is usually on the top side of the ebonite feed. 2019. 10. 5.
Ebonite Feed 1st Gen. V1 (5-10-2018) This is my first ever created ebonite feed. The ebonite feed is naturally superior than plastic feeds, when it comes to wettability. The ebonite is made of natural rubber and sulfer + some additional stuff. The reason ebonite is wettable, is because of its high microscopic porosity. At the surface of the ebonite, the sulfer eventually dissipates into the air over time. when this sulfer is gone f.. 2019. 10. 5.
