Solid Machined Titanium Nib prototyping (Research #4) Today I conducted actual machining of the titanium grade 5 alloy. I was a bit worried because on the internet there were comments warning about machining titanium.since titanium has poor heat conductivity, it will burn up the tool if parameter is not correct.Also, titanium has tendency to work harden, which is a headache. So, it was important for me to get the feeling of how the titanium reacts .. Solid Machined Titanium Nib prototyping (Research #3) Hello, today I completed the prototype plan for the solid machined titanium nib.I completed the design and required manufacturing methods.In the second research post, I leaned towards non-through hole design,but after more research, I concluded that the through hole type is more suitable for manufacturing.1. A method to align the angle of the feeder is needed, so I designed certain part of the f.. Solid Machined Titanium Nib prototyping (Research #2) In the previous research log (#1), the prototype was through hole nib type.Today's prototyping focused on no hole nib type (blind hole) compared to through hole type, no hole type seems to have following advantages:1) various nib design is possible because one feed design is compatible with all of them.2) since the feeder is located internally problem of angular feed alignment is gone.3) feeder .. Solid Machined Titanium Nib prototyping initiated Hello again, this is Eureka admin (The fountain pen researcher)Today I announce the initiation of solid machined titanium nib prototyping. Below photo shows my prototype pen, made when I was in college (around year 2010~2012).it was called "waterdrop pen"The pen was made from aluminum alloy.Since this was just a prototype pen, there were many limitations. there was no tipping, so the aluminum al..

Nib grind service initiated (for eureka fountain pens) Hello, this is Eureka admin (The fountain pen researcher) so far, especially for non-urushi fountain pens, only bock M nib were available.I avoided finer nibs such as EF / F, because I trusted M nib quality the most.because of this, other nib sizes were not available for purchase. however, recently I did some nib grind for some customers.Bock M nib is turned into different nib sizes, by nib grin.. Diamond Symmetry (Ultem) completed Development of diamond symmetry (ultem) has been completed.Recently I've been working on this project. some notes:1. Diamond machining precision improved2. Ring design added to end face of cap and barrel.This will be more resistant to scratches than plain flat surface. Currently working on the production of this model. Thank you.

Slim Asymmetry Manual ◆ Regarding the compression / expansion of air (4 possible states)Due to the nature of its peculiar design, both the cap and end plug are sealed with O-ring.This induces some characteristic compression / expansion of the air inside the barrel, depending on open / closed states of the cap and end plug. 1. If the cap is closed, then the end plug is closed:Compression will occur inside the barrel. ..

How to apply soft pad to your Eureka Pen rest *This tutorial is strongly recommended for eureka pen rest owners! This tutorial will show how to add pad to your eureka pen rest.Ebonite itself is a fairly soft material so it doesn't really harm your pen. (although not perfectly. even wood is not 100% safe in this regard due to small friction that occurs over time).However, adding the soft pad will eliminate even the slightest possibility of y..
