nib surface treatment study This is my recent nib surface treatment studyI recently acquired plain Bock nibs from Germany.which, to my surprise when magnified, the polishing didn't satisfy me.so i started a little study. in the future i am going to do following research:1) nib engraving on plain bock/jowo nib2) solid 14~18K gold sheet (in certain shape) micro welding to stainless nib3) gold (various types), rhodium.. 2023. 10. 21.
5th gen ebonite feed v2 developed Following has been changed: 1) frontal top portion thickness changed 2) external rib increased by 3 3) internal groove (top) increased by 3 A total of 159 cutting process used to complete this feed left: v2, right: v1 2023. 10. 18.
ebonite feed (5G) + CON-70 fitting test The following have been observed during the fit test: 1) compared to 4th gen ebonite feed, which used a screw type ink converter, the con-70 increased ink capacity by 3~4 times. 2) when filling the ink, i noticed i have to dip deeper into to the ink bottle to achieve stable ink fill. compared to 4th gen, the dip amount increased. i think this is due to the quick suction of the ink by Con-70, as .. 2023. 10. 17.
5th Gen Ebonite Feed developed Finally completed the 5th gen ebonite feed the following have been upgraded: 1) super precision attained with ebonite material 2) more complex internal (inside grip) structure 3) equal level of complexity as plastic feed 4) high precision fit of given nib, through 3D nib groove machining 5) high level of fit, even without heat setting 6) Con-70 converter compatible 7) stable eye dropper performa.. 2023. 10. 17.

B & C for Urushi (new version) completed hello guys, new update for the new version of urushi pen development the following has been improved, compared to previous version: 1) internal & external thread is pretty much perfect now 2) the end point of internal & external thread is "escape type" previous type had a groove for thread tool escaping, which reduced strength/durability at that groove spot. 3) barrel and cap end contour more fl.. 2023. 10. 10.
Dodecagon Cigar Symmetry (Ultem) Developed Today i completed the grip section for the dodecagon cigar symmetry (ultem) now, the project is complete. for the grip section, i wanted to do dodecagon as well. unfortunately, it was uncomfortable to write with, due to the large spacing of the angles. so i tried 24, 36 angles. overall 24 angle was best. the following has been aligned: 1) barrel, cap, grip angle aligned 2) bock nib unit, when in.. 2023. 10. 3.
Dodecagon Symmetry "Cap" completed This time i completed the dodecagon symmetry ultem (cigar type). in the last post, i presented the dodecagon ultem barrel, which was quite hard to do. however, this time the difficulty was at least 2x. it was especially difficult for following reasons: 1. when closed the barrel and cap angle must line up accurately 2. there's three different ways the tripple thread engages when it closes. even w.. 2023. 9. 27.
Asymmetry Diamond Dodecagon Cap developed Asymmetry Diamond Dodecagon Cap developed This was a bit ambitious project for me, because i have not ventured into multi-facet machining. the required precision and requirement was quite high, and took months of hard work to master. the multi-facet comprises of 408 small triangles. depending on the view angle, the reflection pattern will change. it requires great precision for all 408 triangles.. 2023. 9. 20.
Dodecagon Symmetry "Cigar" Barrel completed So far, i could only make linear (rod) dodecagon. This was due to precision issues. the level of precision required is quite high, even for Rod dodecagon, for "Cigar" or Taper dodecagon even more precision is required. thanks to recent research, i successfully developed "Cigar" dodecagon barrel. This was my first time making parts from Ultem material (Germany, high quality) since it has a bit le.. 2023. 9. 16.

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.

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.
