Your videos are so much fun to watch and informative at the same time. They are unlike any other fountain pen channel out there, that's what makes this channel so good. Keep the videos coming Bud.
This video is why you are the best fountain pen related channel. You are super detail oriented and also explain things in an easy to understand way. Thanks!
y'know what I really liked about this video (watched half a few hours ago, half now) is that so often I forgot whether you were speaking from the perspective of the consumer versus the designer or manufacturer. I love the vibe! a great video mr bud sir once again much appreciation to ya
Thnaks. It's a little bit of everything as far as perspective goes. Im a fountain pen consumer/enthusiast just like everyone else. At the same time I can't help but think like an engineer and wonder how it was designed & then built and think of how I would do it and the challenges that I'd run into. Then in turn the possible solutions. It's almost reflexive. So much so I think that everyone thinks the same way since its so natural for me it must be for everyone else too 🤣. I'm such a nerd LOL 🤓
Oh Doodlebud, you should upload a video everyday. Idk. Talk about whatever you want. Review a stick. Make a video about anything. I’d watch it. I enjoy watching your videos. Great job. 👍🏻 you and Unsharpen are my favourites youtubers 😀👏🏻
A material I sometimes see in mechanical watches, but not in pens is tungsten. There are of course weight issues, not to mention difficulties in things like screw threads. (Some tungsten watches use pressure fitted steel pieces + steel screws). Perhaps just a plastic pen with some tungsten hardware -- ring and roll stop, might be possible. Another metal that might work for some hardware is chrome cobalt.
I’m a believer in the MUJI store approach to product design . Terrific detailed over view of the MUJI pen , which pen I own and until now was curious about the MUJI approach to making a pen.
Great video! You provided a lot of food for thought. I sometimes wonder why certain design decisions were made and how they work (or what happened when they don't). Your video helps to explain what and why some things are the way they are. Thanks!
So interesting. Always learning something from the DB. I have yet to find another channel that provides this perspective in such depth. And such eye candy! I would enjoy seeing a video on resin and plastic in pen construction.
Tldr- Good vid! This is by far my most anticipated video of yours. I've always wanted to know what depth of knowledge goes into design. I do software and physical engineering always seemed so much cooler and more clever. Software is too easy to iterate on and improve after the fact.
The whole presentation was great. Thank you. Particularly interesting was the bit on the Muji which I appreciated already, but now even more-so. "It's all made of tubes." you say. Truly amazing for a relatively low priced pen. Someone engineered this curious little complexity and did it well.
I wondered about that pen then as I did this video I took the time to have a closer look and BOOM there it was. Really slick how they did that. I wonder if they are standard thin wall tubbing sizes or all custom extrusions
Thanks for a very interesting and informative review. There are many things to consider that makes the pen hobby so much fun after you have some experience and begin to dig into those things.
Excellent overview of the many styles of fountain pen bodies. Normally I go for the resin bodies due to the infinite selection of colors and styles (swirls, stacking, cracked ice, stripes etc.). Metal pens are just as nice but a nice lacquer finish is a plus. I know brass is the metal of choice for many manufacturers. That aluminum, steel and titanium are also being used is great, though the heaviest pens tend to use steel which I assume has a marger density / mass than brass. The closure mechanics have been of interest. I do like the hook system on the Visconti over the usual threads. Snap and recently magnetic closures are really good (the Monteverde Ritma is a great example). As for grip, I am not a fan of the triangular grip. Metal sections can be too slippery. The ones with a groove like the ēnsso titanium pens work perfectly. The step down feature on the Leonardo and the Wing Sung M800 is nice but the final verdict is still out for deliberation. Great overview.
Enjoy your perspective, as always. Here's a question, a couple actually. 1. If they can use insert injection molding for an inner cap for the nib why can't they design a pen with an insert molded bladder for the ink? And 2, why can't they use overmolding technology for pen grips like disposable razors? Both of these would allow larger capacity ink without burping. Regards
About cheap pens - all Jinhao pens I've got from Aliexpress had markings of testing with ink, Hero - maybe just one of all models I've ordered (most expensive, fully metal and without model number, writes decently without any issues, probably flagship model) had inkmarks on feeder (most of those are worse than Jinhao in terms of material quality, nib writing quality and so on), noname whatever - none had marks (but write acceptably, got only two of those because kinda transparent demonstrators). PS I don't remember extra polishing Jinhao nibs much or at all but the rest I just had to polish at least a bit, some - more than a bit.
When discussed materials, I can't believe you didn't mention the Homo Sapiens. An indestructible lava pen. May be you were trying to make a point in how pen companies can miss things, so you could you, and perhaps you were wondering if a keen eye would pick up on it. Anyways, I am just messing with you. Good video as always. Made be rethink a future purchase of the Diplomat Aero.
Oh man I could spend so much time on materials. Just stuck to metal & "plastic" for this one. The term plastic drives me nuts too! It seems plastic is used to generalize the material as the same thing vs the differences between metals is always recognized. When I hear "It's just plastic," its so revealing that the person saying that, has no understanding of materials whatsoever 🤣
Gosh, I wish you had 'subtitles' when you were discussing material of construction, holding up pen after pen: A wee caption for each (make/model) would have been swell. Still, love the vid: Chemical Engineer here (ret'd.), did time in a pilot plant, and spent time at the bench. Thanks for the lecture.
It's tricky to give a caption for each pen I grab as I go through when having so many pens handy. I can do it but just barely have enough time for my editing as it is. Might lean on you when I have some chemistry questions. Definitely not my area of knowledge
Only issue with that would be how are the cap bands secured. Many are friction fit or crimped. Could maybe do it with magnets like Visconti does their end jewels on the caps with the whole magnetic deal.
Please review the Jinhao 80 ( ultra inexpensive pen ) . The Jinhao 80 looks like your favourite pen the LAMY 2000 but has a LAMY studio resemblance once the cap is removed. The Jinhao 80 has a converter not a piston but apart from that seems to a non engineer to be an improvement on the LAMY 2000 for under $10 !!! Please consider
Would there be a way to adopt this for visual inspections on screens? Unfortunately, you don't notice until you hold the pen and feel the small discrepancies on most bad designs.
This is why I share what I do. I take these ideas and do my best to look at pictures or reviews before I buy them and look for the things I mention. Even if they don't directly talk about them or point them out I zoom in on pics/vids and look closely for any issues or things I can figure out on how its built.
I did a review on it so you can find out more. The info on where I got it is in the video description: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-B1DJuuBxAuQ.html
FeCl is what I used. It reacts with the Ti when its above 600C. All good proper PPE and had ventilation. Here's a video all about it and I did it to a nib as well: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_FNfCYCT_4s.html
Good. And really those comments weren't so much for you as for any silly person who'd start Messing with Dangerous Goop without checking the safety info ..
