Do not slide the surface across with the stopper without protective layer, it will cause scratches. always pry open the stopper, then place it at desired spot. I am not responsible for any consequences caused by mistakes while installing the s.. Asymmetry dodecagon cap developed 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 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.. 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.. 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) "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. "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.. 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.. ㅤ Eureka Symmetry Model developed new symmetry model has been developedMaterial: ebonite, special plastics etc.design not suitable for urushi coating (a different model will be created adequate for urushi coating in the future) below photo shows a sample of this model (unpolished state, a further polishing process will be applied) comparison to prior symmetry modeloverall thickness and length reduced(cap size reduced, below phot.. . . under normal low-lighting under bright lighting such as sun / led lamp etc. engravings: cap: butterfly barrel: butterfly . . . . eureka symmetry eureka symmetry . . . . . . . . . normal lighting hard to see details bright lighting bit of detail can be seen it will take much time for outer thick layer to clear up a bit. when urushi is exposed to lighting/sunlight outer layer becomes a bit clearer more details should be seen in the future . . under normal low-lighting under bright lighting such as sun / led lamp etc. engravings: cap: crane, cloud barrel: crane, cloud 이전 1 ··· 8 9 10 11 12 13 14 ··· 24 다음
