eureka asymmetry diamond dodecagon cap fountainpen has been developed (protoype) below is prototype pen, actual production pen will be different production will begin soon! 2023. 9. 12.
Diamond & Ruby machining process developed For a while, i've been researching for multi-facet precision machining. This is a highly complex process requiring utmost precision. ideally 0.01mm precision is required, however, this is very difficult because all the inaccuracies add up. so far, i've achieved 0.04mm precision. i think 0.1mm precision is okay for sale. now i am trying to achieve 0.01mm precision, although this is gonna take muc.. 2023. 9. 10.

Asymmetry dodecagon cap developed 2023. 7. 28.
new Dodecagon cap developed (ebonite material) new dodecagon cap has been developed in ebonite material.captop logo & side engravings applied.below sample has not been polished 2023. 7. 27.
Prototype gen5 ebonite feed ink fill test (Con-70) I created a very basic gen 5 prototype feed, for ink fill test only airchannel is applied (some omitted) all other features not applied (rib, ink channel, etc.) this is the side view of the test feed air channel from converter is connected to the hole the hole is drilled to the center of the feed a long thin hole is drilled all the way to the aforementioned hole drilling thin-long hole is not ea.. 2023. 6. 21.
Prototype drawing of 5th gen Ebonite Feed (research log 6/18/23) i will be developing my 5th gen ebonite feed. based on years of experience on my 4th gen ebonite feed, i have found some areas i can improve upon. 1. first consideration is feed diameter usually #6 nibs have 6mm diameter feed. in order to make ebonite feeder more stably with greater durability i've chosen 6.5mm, same as the 4th gen predecessor. the nib is designed for 6mm feed, but 0.5mm diamete.. 2023. 6. 18.
New exotic materials to try... These are Super engineering plastics very high quality from germany, very expensive... looking forward to trying out these materials, although it will take much time... PEEK, Black PEEK, PEEK (glass fiber 40%) PEEK (carbon fiber 30%), PEEK (graphite-teflon), PEEK blue (medical grade), Ulterm (galssfiber / natural) 2023. 6. 17.
"Arc Grip" type has been developed "Arc" grip type has been developed in PEEK material. so far, 3 types of grip designs are completed in PEEK material. 1. normal (taper) type 2. super grip type 3. arc type since an adequate amount of research is completed in grip section, i will move onto further developing other parts of the pen. 2023. 5. 25.
"Super Grip" type has been developed "Super Grip" type has been developed in PEEK material 54 individual micro "protrusions" are precision-machined individually. these bulges fits between finger print ridges, enhancing anti-slip properties. different boundary lengths were tried for choosing best overall aesthetics. in the end i chose the one in the last picture. it seems quite adequate, not too excessive. in terms of performance, i.. 2023. 5. 24.
Eureka Symmetry Model (PEEK material) new symmetry model has been successfully developed in PEEK material This is a fully precision-machined pen from solid peek rods. we only use the PEEK material imported from Germany (high quality) PEEK is a hyper-performance plastic (or super engineering plastic), that has following characteristics: 1) superb chemical resistance 2) high temperature resistance (max 260C) 3) superb strength, wear r.. 2023. 5. 18.
