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.. 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.. 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.. 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.. eureka asymmetry diamond dodecagon cap fountainpen has been developed (protoype) below is prototype pen, actual production pen will be different production will begin soon! 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..

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.

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..
