● R&D Log184 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.. 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... 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 .. 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.. 3 Slotted "French Bread" Pen Rest This is "Master Original" slots precision angle machined, for best pen rest angle. middle slot is slightly less deep than the others. ◆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.com/profile.php?id=10005 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.

(3G V2) Harder type of argentium nib developed. Previous types were softer, due to finer frontal nib shape. this type, the nib is firmer.

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.. 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.. high level of nib polishing achieved, through research as opposed to previous polishing method, a new high polish method was successfully developed. newly produced nibs will be polished with this method. ◆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.com/profile.php?id.. Eureka V8.3 Symmetry (October, 2019) Upgrade List (Compared to Previous Version) 1) design changes to grip frontal section 2) grip length reduced 3) external design changes to make it more ergonomic Eureka V8.2 Symmetry (September, 2019) Upgrade List (compared to previous version) 1) double start thread used 2) overall thickness reduced 3) grip a bit longer 4) internal design changes to improve concentricity and stability 5) fully usable as eyedropper (ink will not seep through threads, because sealing happens before it) 6) Internal design changes for smoother capping. Eureka V8.2 Asymmetry (august, 2019) Upgrade list (compared to previous version) 1) External design changes for better postability of cap 2) Internal design changes for better postability of cap 3) Internal design changes for smoother capping Eureka V8.1 Asymmetry + 14K nib (August, 2019) Upgrade list (compared to previous version) 1) Thread changed to 3 start thread for grip and cap. 2) external design changes 3) cap internal design changes Eureka V8.0 Asymmetry (May, 2019) Due to, increased request for Asymmetrical deign that is cap postable, this design was created. Over all size is bigger than 149 (the nib is smaller, but bigger than #6) grip section is thicker than symmetry counterpart. Reduced grip ~ barrel transition bump smaller thread pitch used balanced feel without cap, just like symmetry. when posted, weight balance a bit to the rear uses Eureka ebonite .. Eureka V8.0 symmetry (May, 2019) Upgrade list (compared to previous version) 1)Barrel length increased 2)cap length increased 3)grip length increased 4)grip frontal section design change 5)grip sealing design changed 6)uses Eureka ebonite feed 3rd Gen. 7)external design changes 8)uses Eureka In-House Argentium nib Eureka V7.7 Symmetry (November, 2018) Upgrade list (compared to previous version) 1) Grip frontal section design change 2) rear gas regulator type sealing design 3) rear tail section added to grip to improve concentricity 4) grip shortened a bit Eureka V7.6 Symmetry (September, 2018) Some of the buyers wanted a less sharper version of V7.5 V7.6 was a sausage type design, whereas V7.5 was sharp cigar type. V7.6 looked even looks a bit cute and very minimalistic. grip length was reduced a bit as well as nib length. also, started making pen pillows. Eureka V7.5 Symmetry (July, 2018) The V7.5 is similar to V7.0. the feed was changed to plastic one, for productivity and stability. eureka ebonite feed 1st. Gen. feed was not bad at all. however, it couldn't achieve same stability as the plastic ones. This is a common problem with ebonite feeds. It is simply near damn impossible to pracically make a feed that functions like plastic feed. there's so many features that needs to be.. Eureka V7.0 Symmetry (May, 2018) Here it is, the V7.0 symmetry. here, the barrel design got its cue from the extreme V4.0, toned down a little bit. It also kept the long grip design from V6.0, with a longer linear section at the front part of the grip. It felt quite good in hand. confortable and nimble. for the nib, a stainless taiwanese import nib was used. for the feed, eureka ebonite feed 1st Gen. was used. this is when i st.. Eureka V6.0 Symmetry (April, 2018) V6 is a more ergonomic design than V5 grip length was yet again increased, as well as barrel length. Eureka V5.0 Symmetry (April, 2018) After the Extreme design of V4.0, a toned down version was created. V5.0 also implemented a small roll stop. The roll stop material was natural stone material called calcedony. It did work quite well. however, it rather looked odd. also, i couldn't guarantee the stone will stay there for decades of use. it was later removed, as i feared it would fall out on its own eventually, even if a strong a.. Eureka V4.0 Symmetry(March, 2018) V4 was considered a failure, due to its extreme sharpness. However, later on the design concept was utilized in some aspects. the sharp drop actually provided some stability when writing. This was a small discovery that lead to small, but incremental improvement. Eureka V3.0 Symmetry (february, 2018) V3.0 focused on only one aspect: ergonomics. grip length was increased, as well as overall length. Eureka V2.0 Symmetry (12/26/2017) After the first prototype, I realized people will be tired out by the solid aluminum design's weight. I searched for a light and sturdy, yet stable and premium material. There were other candidates: cellulose, Acrylic, wood, PEEK, etc... however, the most reliable and durable, yet good looking one was for me, ebonite. Cellulose and acrylic looked fantastic. but cellulose was tricky material in t.. Eureka V1.0 Prototype Fountain Pen (2013) This is when the adventure of my fountain pen bagan! all the parts made of aluminum alloy. the nib was a conceptual design that i wanted to try. although it would write, since there was no tipping, it would wear out fast. i was hoping the oxidized aluminum would be thick and hard enough to prevent wear. in reality, it didn't work out so well. although it was a failure, it kick started my adventu.. (3G V1) 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.
