Easy Con-70 installation method *** We only officially accept Eureka ultem ink cartridge as main ink storage device for our pens. We no longer officially recognize Con-70 / Con-40 as converter for Eureka fountain pen models. Although they are still compatible, you must read con-70 related manuals / tips before using them. It is tricky to get it right, although if you are skilled / experienced with the system, it should be fine..
Dodecagon symmetry Peek Black has been developed Hello, this is Fountain Pen Research.Today, I completed the development of a Dodecagon cigar symmetry fountain pen with PEEK Black material.As with the Dodecagon diamond symmetry, the same PEEK black material was used.Quality grades are classified into A+, A, B+, B, C+, C, etc. (barrel & cap only, grip parts are mostly grade S).The cap length has been slightly reduced compared to the previous Do..
Micro-blasting treatment applied to Solid Gold nib Hello, this is Fountain Pen Research.To this date, I researched the microblasting process on Bock stainless steel nibs and successfully applied it.This effectively removed scratches from batch polishing process by Bock.This time, upon request, I applied the microblasting process to an 18K gold nib for the first time.Solid gold is a softer material than stainless steel, so it required more delica..
Solid Ebonite Pen rest & Nib Remover Tool Research Hello, this is Fountain Pen Research.This is research on solid ebonite penrest and nib removal tool. The previously developed pen rest was a cast-type using composite resin.This is the so-called "baguette" pen rest that many users are fond of. This time, I decided to make it with solid ebonite material.I plan to make a variety of shape types,1. Round 2. Square 3. Diamond shape There are two type..
Dodecagon Emerald Symmetry developed Dodecagon Emerald Symmetry has been developed. after completing the dodecagon diamond symmetry,I started working on the dodecagon emerald design. there are numerous emerald shaped rectangles on barrel & cap.due to the nature of the emerald design, angles are not sharp,therefore the shapes are not very sharp looking, like the diamond one.it is a subtle, yet defined design.
Dodecagon Diamond Cigar Symmetry PEEK (TAN) has been developed Hello, this is Fountain Pen Research. Today, I completed the Dodecagon Diamond Cigar Symmetry PEEK (TAN). Compared to South Korean-produced Black Peek (raw material: Germany), Peek tan Color is 100% German produced. ​Although peek tan color very rarely has dark spots, It showed much more consistent quality than Peek Black. Peek black pens are divided into grades: B, A, A+, and S (almost none). I..
typical cosmetic defects of Black PEEK Recently, I started making pens with Black PEEK. I purchased the rods from a South Korean manufacturer. they used German PEEK pellets to produce the rods. Despite my nearly perfect pen making process, when I started machining the material, I noticed several types of common cosmetic defects. 1. white dots (common) 2. tiny metalic dots (rare) 3. small cavities (common) the white dots are the most ..
Bock two-tone engraved nib surface treatment test I've recently experimented with surface treatment with bock nib. I've found some new things out 1. engraved features deepens2. hammered texturing seen when magnified (can be altered)3. the slit is affected is well, so i need to take extra care(below I just did it without care, because I didn't know)   original (before treatment)lots of scratches can be seen,the entire nib is full of scratches, a..
Dodecagon diamond cigar symmetry developed (PEEK Black) Dodecagon diamond cigar symmetry has been developed (PEEK Black). changes:1. barrel drill depth increased by 3mm (for reducing Con-70 button interference @ end)2. precision Barrel & Cap angle allignment ( ±0.001mm precision for proper angle positioning)3. below pen is non-engraved captop version (engraved ones will be produced as well, although this will take time)*some people wanted non-engrave..
Dodecagon diamond cigar symmetry barrel developed (PEEK Black) Dodecagon diamond cigar symmetry barrel has developed (PEEK Black) it was my first time machining with the peek black material.my first impression is "I sort of experienced hell".although a bit less now, still feeling a bit of burden just by looking at it. well, things have stabilized now, although not perfect.there's still room for improvement, I will keep trying... I will soon complete cap as ..
PEEK (Black) 8 types of grip developed PEEK (Black) 8 types of grip have been developed.There were some difficulties, because it was first time handling the new material.however, i was able to overcome them through hard work. now i will move on to developing diamond cigar symmetry (peek tan).thank you. from left:1. one-piece2. one-piece thick arc3. shift arc4. super grip fine5. full arc pipe6. hourglass short7. hourglass arc8. vintag..
