JSolinger posted a topic in The Write StuffI like fountain pens, I like ink, I like paper and i like machines. So I use them togerther. The below image started out as a doodle and I felt I should see it through to the finish. The image is drawn using a Lamy Safari with and EF nib. The paper is 110# card stock and the ink is Aurora Blue. If you enjoyed this drawing I have others on my YouTube channel: Joseph Solinger
Jamerelbe posted a topic in Fountain Pen ReviewsIn June of 2015 (I think it was) I first became aware of a new pen project being launched on Kickstarter. Kelvin Verrett, the guy who designed the pen, describes himself as a “Mechanical Engineer working in Aviation” who uses his spare time to “create innovative products in my small CNC Machine Shop”. This was his second Kickstarter project - but it looks pretty certain it won’t be the last. As anyone who was watching the project will know, the original design was for a short (4.45in) pen, machined on his CNC lathe, that would be suitable for everyday carry. Backers could choose from titanium, copper or brass bodies (with a titanium clip), and decide whether they wanted a fountain pen, or a pen that would accept Space Pen / G2 gel pen / Parker pen refills in the barrel. Various other options became available as stretch goals - including a lanyard cap option, the capacity to buy extra tips, and the option of buying a longer bodied pen (5.45in length). One of the things I really enjoyed about the Kickstarter was the ongoing communication - all the way through, Kelvin was providing entertaining updates on his Instagram channel, that kept us up-to-date with design changes and improvements, stretch goals, and (during construction) the various delays and challenges that he had to overcome. By the time the campaign had ended, I’d changed my order several times - settling on a titanium and a brass pen, both the original (shorter) size, plus a lanyard cap, plus an extra brass tip to accommodate a Space Pen refill. I don’t want to write a lengthy review - just a few details, a few comments, and some pictures - but let me say up front I was really pleased to receive these pens a couple of weeks ago. The titanium pen is still in my possession, while my teenaged son is putting the brass version through its paces. Without further ado, a picture first of all: http://i.imgur.com/hgi6n8b.jpg The pen is beautifully machined from solid titanium rods. The cap and barrel have slightly different diameters (10mm vs 9.5mm), making this a farly slender pen. Capped, the pen is 114 mm long; uncapped it’s only 107mm - which means the end of the barrel only just extends beyond the webbing of my hand: http://i.imgur.com/6nATmpH.jpg I purchased the pen to be a portable pocket pen, and it fits the bill for that purpose admirably - I worried the extra inch might make it too long to sit comfortably in my pocket, but that would be an option for anyone wanting to order a slightly longer pen. It’s perfectly comfortable for me to write with - but better suited to shorter note-taking sessions, rather than writing a multi-thousand-word essay! By way of comparison, here’s a picture of how the titanium and brass TiScribes (capped) line up against a few other pocket pens - a Kaweco AL Sport, a Stipula Passaporto, and a TWSBI Diamond Mini. http://i.imgur.com/kGXYrPT.jpg These pens all post, of course, so are longer when deployed for writing - but again, the TiScribe is just long enough (for my medium-sized hands) to write comfortably. As I mentioned earlier, I ordered my pens with an optional extra lanyard cap (no clip) that would allow me to carry it around my neck, plus a brass “pen tip” to convert to a ballpoint / gel pen: http://i.imgur.com/vyiOaVt.jpg The threads that hold the cap onto the barrel are nicely machined, and ensure a tight seal. The threading between the grip section and barrel is reversed, so that the barrel doesn't accidentally unscrew when you're trying to uncap the pen - the unintended consequence of this is that if you try to overtighten when recapping the pen, the barrel begins to unscrew... but that's better, I think, than exposing the cartridge / converter when you're wanting to write! Looking inside, the 'standard' size pen takes short standard international cartridges, or the Monteverde mini-converter - the larger ("full-size") version will also take a full-length cartridge converter. http://i.imgur.com/czID92z.jpg The threads that hold the cap onto the barrel are nicely machined, and ensure a tight seal. The threading between the grip section and barrel is reversed, so that the barrel doesn't accidentally unscrew when you're trying to uncap the pen - the unintended consequence of this is that if you try to overtighten when recapping the pen, the barrel begins to unscrew... but that's better, I think, than exposing the cartridge / converter when you're wanting to write! When Kelvin first conceived of the project, his intention was to supply the fountain pen version of the pen with Kaweco nibs - given the volumes eventually involved, he was able to source his nib units directly from Bock (060 size), with standard Bock branding: http://i.imgur.com/HDORqow.jpghttp://i.imgur.com/x1bCeX5.jpg You could easily swap in a Kaweco nib unit, though - and I'm pretty sure the smaller nib units Goulet Pens sell for the Karas Kustoms Fountain K will fit too! I'm not sure much else to say about the pen - other than to say I'm really pleased with the purchase! I understand Kelvin is making a few minor adjustments to the design, and planning to release version 2.0 sometime soon - you can keep up with developments on his Instagram (https://www.instagram.com/one2tencnc/) or on his YouTube channel (https://www.youtube.com/user/CNC2Live). If you have any questions, I'm happy to try and answer them - feel free to leave comments below!
In Aurangabad, Maharashtra, India, there is a pen shop called "Abhay Pen Agencies". In addition to selling other brands, this shop also manufactures and sells their own brand pens. their brand name is Mohi. The Mohi pens are made in a variety of materials like Ebonite and Acrylic. These pens have been documented by amk and wdp4baaz on FPN. You may want to read those reviews also, I have provided the ready links: https://www.fountainpennetwork.com/forum/topic/281732-mohi-harmony-fountain-pen/ https://www.fountainpennetwork.com/forum/topic/288813-mohi-ebonite-eyedropper/ https://www.fountainpennetwork.com/forum/topic/288482-visit-to-two-old-cities-and-some-new-indian-fountain-pens/ https://www.fountainpennetwork.com/forum/topic/287448-mohi-tanishq-new-indian-acrylic-beauty/ https://www.fountainpennetwork.com/forum/topic/282503-mohi-ebony-fountain-pen/ In simple terms, the word Mohi simply means attractive. I was attracted to the Mohi pens and was looking to purchase an example. Here is where Pune based FPNer WDP4BAAZ entered the picture and gave me a wonderful gift of this Mohi "Ebony" eyedropper that he had managed to purchase through a contact in Aurangabad. The pen: http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0819.jpg Opened: http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0820.jpg It is a simple Dropper filled pen: http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0821.jpg Usually the Indian Ebonite pens are turned on a manual lathe by an artisan. In the case of Mohi, the job of turning is done by a CNC, however CNC machning is just one part, fitting, assembly and polishing are all manual steps and have to be still done by hand. CNC gives the advantage of parts interchangeability, a feature missing in fully handmade. You can see from the following pic that the barrel is 2 piece and then nicely joined from inside: http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0822.jpg The branding on the clip: http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0823.jpg The ink view window remains slightly exposed even when the cap is closed fully, a nice touch: http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0824.jpg Some pen users in India have a tendency to grip the pen right at the bottom of the section, near to the nib. Such users also demand that the distance to paper be as small as possible, thus we see deeply inserted nibs. The Mohi nibs are typically very deep seated, even on their jumbo pens and this small Ebony is no exception. The nibs are not generic, but are rather branded Mohi in a simple way. The nib is tipped and of Fine width. http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0826.jpg http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0827.jpg The Ebony is a shade larger than the M200(This was a lovely gift from and a memento of meeting another FPN friend, Kaweko in Heidelberg) http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0829.jpg http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0831.jpg Well, how does the Mohi write? Very well indeed... The nib is very smooth for a nib this fine and the line is appropriately dry for a student who has to write a lot on poor quality thin paper notebooks. Here is a writing sample: http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0836.jpg On the back ground is the lovely covering letter in Marathi, written by WDP4BAAZ and enclosed with the pen when he sent it to me. http://i991.photobucket.com/albums/af39/hari3171/Mohi%20Ebony/IMG_0837.jpg I hope the readers found this review useful. Cheers! Hari
