Reply Function has been fixed. now everyone can leave replies. sincere apology for all the inconvenience . Omas custom fountainpen (#5 nib, for urushi) this omas custom uses #5 nib, which is quite small. 3mm shorter feed is used for this particular size. pen finish is rough, because it is for urushi coat. also installed recently developed teflon grip protector inside the cap teflon grip protector, research finished when opening and closing the pen, the grip frontal area and inner cap area inevitably cause friction. this is especially noticeable for vintage grip style designs. below is 1st gen eureka grip design, which is loved by many. however, as users continue to use it frequently, severe scratching is inevitable. this is aurora 88. grip design : vintage style much scratching and dulling is observed, @ f.. parker duofold international retipping (part 2) this post is part 2 of "parker duofold international retipping" after welding, i proceeded with the slitting. this is even more difficult than welding. from the previous post, one can see the extra gold weld material @ the right tine has been equally removed. this was quite difficult process. also, from the below photo, it can be seen that the frontal part of the nib has been repolished, while n.. parker duofold international retipping (part 1) this is part 1 of the parker duofold international retipping. a new phenomenon was observed, which wasn't previously noticed! this is right before welding the nib, after a bit of grinding work to remove the iridium. left tine was thicker than the right, probably due to welding/slitting error from manufacturer. from this photo, the right tight has a bit more gold material, as a result of grinding.. 8 urushi colors developed orange yellow mint green mandarin white (bright beige) magenta red light green urushi polishing technique, much improved compared to previous technique... below figure is an estimation based on feel and observation. unfortunately, i don't have the scientific/precision equipments to do that. 1) surface smoothness improved by 2~3x (observation under microscope) -micro bumps are no longer present 2) final polishing improved by 3~4x (observation under microscope) -even the most difficult area to polish, are now equall.. dodecagon symmetry v1.1 (for urushi) nib size comparison pilot 743, eureka Au-Ag, aurora 88 nib overall shape improved through personal research #1 --> not enough bending amount, thought to be an effect of "spring-back" phenomenon. #2 --> V-bending phenomenon @ skyblue dot, thought to be inevitable. so far, #1, 2 was wrongly thought to be a consequential result of bending a springy sheet material. increasing press pressure by 10x improved overall shape. especially, improving #1 was vital, because when the nib is slitted, a deformation oc.. glossy finish done for both urushi & nib (from previous post) not being satisfied with the finish, i applied the final polishing for urushi. (same pen from previous post) also the high glossy finish of urushi caused mismatch between urushi and nib. therefore, i also gloss polished the nib. now, it's complete.... harmony dodecagon symmetry v1.1 upgraded from v1.0: 1) design easier to urushi coat 2) end portions rounded to facilitate production 3) cleaner angle cut 4) grip shared with symmetry v9.2 5) grip front part more rounded (*vintage/aurora style grip design is prone to scratches when opening and closing cap, a unfavorable design for urushi coating) (below grip is designed to reduce scratching when opening and closing cap) 6) grip.. edson & visconti nib retipping (part 2) retipping completed for: edson & visconti nib! check part1 for what it looked like before retipping work :https://eurekafp.com/257 edson & visconti nib retipping (part 1) i've received two exotic nibs. one is 18K edson, the other is visconti palladium 23K both nibs are in bad condition. edson barely has a tip, visconti doesn't have any. visconti palladium 23K may be a challenge, as it is very exotic material. this is before the repair state: edson: visconti aside from the exotic shape of edson, welding was straight forward. palladium 23K required much more energy.. MontBlanc 146 Retipping the pen owner Kang (from S.Korea), sent me this pen. as matter of fact, this is the second time i received it. first time was a year ago, and i was not confident enough to retip the nib. however, a lot has happened since then, and I have obtained higher skills regarding nib fabrication. after a year or so, i had much more proficiency in following categories: -welding -slitting -nib smoothing / p.. Urushi technique V5.0 developed ! urushi technique v5.0 has been developed! currently many different colors are prepared. urushi coating will happen very soon. compared to V4.0 process... 1. durability improved by at least 10x, compared to v4.0 (special surface treatment to ebonite to faciliate absorption of the urushi / higher quality refined urushi laquer used than previous) 2. compared to v4.0, special surface treatment enhan.. 이전 1 ··· 14 15 16 17 18 19 20 ··· 24 다음
