I'm a mechanical engineer. I can appreciate this stuff. hahaha The world of fasteners is craaaaaaaaaaazy huge and varied. British standards, Japanese standards, German standards, Imperial, metric, on and on and on. And the societal bodies that standardize dimensional features of fasteners also update their standards periodically.
Very informative video. Threading the caps has always been something that I have taken for granted, until now. I use a vintage Camlin 36 which has a screw cap and upon closer inspection found it to have 4 entry points on the thread. As per Brian's method, it takes 2 complete rotations to take the cap off.
That Pilot 100th anniversary is my grail pen. Such a perfect way to celebrate their 100 years 😍 This was a helpful video! I have been wondering about threads and why some were the way they were with their behavior, this was enriching to learn more!
This is absolutely something that matters to me. I hate multiple turns. I much prefer a snap cap. Thanks for your attention to detail! This is why Goulet Pen Company is the best and earns customer loyalty.
I love the dynamic between you two. I always browse the technical specs to make sure the pen isn't too short and I like fewer cap rotations. Thanks for the information.
This was actually one of my favorite Write Nows! I have been thinking a lot about why some pens take longer to uncap recently and this helps a lot... it also makes me want a Homo Sapiens more 😭
That was very interesting! I was just thinking this week about all the rotations I have to go through on my Shark Pen compared to my Edison. Perfect timing!
But it writes well and feels good in the hand and I want to use it every where. However I don't because if I am taking notes I forgot what I wanted to write down by the time I get the cap off
Not only do we have to unscrew the cap, but we need to unscrew the top of the pen to get the ink to flow, right? I do 5 turns on the top of my pen, and I keep it on my desk too. It’s a great eye dropper pen. 😁
Glad you brought this topic up. It certainly is an important factor for me. 1.5x is max for me. My favorites are mostly under 1 full turn. Pelikans seem to do this well.
Ah yes, I was offered a Namiki Yukari Royale for 100.00 but when I saw that it would require an extra 1.5 mm turn to line up the snowy egret wtih the clip, I laughed and said, No deal!
Threads are actually one of the 5 or so basic machines. A thread is an inclined plane wrapped around a cylinder (bolt) or a cone (wood screw). Other basic machines: Lever, pulley, axle, & wedge. A toothed gear is sometimes also noted, but a gear is a series of levers (teeth) cut into a pulley.
Brian mentioning Cirque du Soleil's contortionists got the Alegria song stuck in my head because they played it on the radio the other day for its comeback (I live near Montreal, where the Cirque comes from :p).
Even though I knew about half of this already (Brian has spoke about multiple entry point on at least two other videos I have seen recently), this was an really fun video and thanks! Really cool!
You two could read the phone book--or something comparable in the 21st century, and make it interesting. I'm betting this video is going to bring out the most technical, pickiest, nerdiest fountain pen comments. It will be like reading the Letters to the Editor of a Mensa Bulletin. I will be back. ;-)
Technically, pitch is the number of threads for a given length. e.g. TPI or threads per inch. (similar to musical pitch which is waves per unit time) The angle of the thread is called the helix angle and depends on the pitch and number of starts.
Lamy Safari and Al-star have click caps but a double thread barrel. If you get it wrong the Lamy logo doesn't line up with the nib. This really does boil my piss!
But for some it might be a feature when they want the logo to be on the other side... :) But when you just want to screw the thing back together it can be really annoying ;) Had it happen to myself multiple times.
Entertaining video, as always! One of my favorite screw cap pens is actually my Monteverde Invincia Nebula (with a goulet nib!). It has a very different feel to it than all my other screw caps pens, maybe the finish or like it's sealing air tight? It has more resistance when it turns but I can't figure out why. Ideas?
Thank you for this nerdy geeky fantastic video. This is something that matters to me in terms of fountain pen satisfaction. And a question, do more twists to cap mean more moisture is retained inside the pen cap? What is the utilitarian purpose of more or less turns to cap and uncap? Or is it just the whimsey of fastening? Thanks.
Guys perfect video for me because it’s becoming a deal breaker, I have an opera master and a custom 823 which I rarely use as I reach for my old Lamy studio more often. Could you PLEASE do a follow up focussing on snap caps and throw in a few large / long options as I and I’m sure many folk have super large hands. I’d be eternally grateful, cheers from Melbourne Australia
My Opus 88 Demo takes 4.25 rotations, but it's worth the hassle. I really like the threads on the Montegrappa Elmo pens, as the engraving always lines up with the clip, unlike my Edison pens which drives me crazy. Franklin-Christoph doesn't have this issue since they engrave the cap. My Leonardo pens always line up the clip with the body engraving if you start with the clip and nib aligned to begin with. Visconti Hook Safe Lock for the win!
This is an important topic for those of us that like things to align. This also comes into play on the pen body. I like the Lamy logo to align with the nib and that can take a couple trys. The trials of us pen nerds. lol 😄🌻
guys i just bought an i dropper pen (moonman m2) and was thinking where could i get silicone grease for it. i was thinking, can you use chapstick to seal it up?
I'm not sure we've ever tried this. I don't think I would recommend it. We sell silicone grease here: www.gouletpens.com/products/goulet-silicone-grease?variant=11884650266667 -Lydia
you should have included the more relevant topic of how the threads come in contact with your fingers while writing and the comfort / discomfort of this. (sharp threads vs smooth ) etc
I have a question that is semi related to threading on and off caps. I’ve heard on this channel not to use alcohol to clean pens due to the potential for damage to the pen. But what about touching/using your pen after you’ve cleaned you hands with hand sanitizer? Since there’s alcohol in hand sanitizer, is there potential for damage if the alcohol from the sanitizer transfers to the pen? Or am I looking to far into it and the amount would be to minuscule to matter?
I suppose if you still had wet sanitizer on your hands and subjected the pen to it repeatedly multiple times over the course of the day, it could inevitably cause problems, but I haven't seen or heard of any issues personally. I would just make sure the sanitizer is dry first. -Lydia
Hi! I have two questions for you. Can I use Lamy ink with Pilot Metropilotan (fine nib) pen? And can I mix two different colour lamy ink together? (to make a more pleasing coulor for me :D) Thank you in advance, for the aswer.
Yes to both questions :) LAMY fountain pen ink is compatible with all fountain pens. I would recommend mixing the ink in a separate container instead of inside the pen, just to be sure they behave well together. Since they are the same brand, it shouldn't be an issue though. -Lydia
@@Gouletpens Thank you so much for the aswer! I will mix them separately :) I just received the Pilot pen today, but I already know that I like it better than the Lamy safari pen :) at least the ink is compatible with both of them ^_^
I avoid pop tops unless I really really like and want the pen the exception to that is the magnetic cap. As Drew said it did prove interesting and its the first time I’ve seen it demonstrated so thank you. I liked your shirt Brian, cool... can I ask you to TRY not cracking your hands near the mic... loads of us do it myself included but near a microphone it sounds really sickening , have a listen. Back to pens I didn’t know Edison used a quad start and cutting multi start threads takes some thought. Kaigula ? Pens are the longest screws in my experience taking or 6 or 7 on the 316 the one that looks like the Parker Duo Fold. Thanks for another interesting Write On. Best wishes to all PenPeople LeZc @@

Not quite. The pitch is not the slope of the threads. It's the distance point to point between threads, commonly the top of one thread to the next, or also 1/threads per inch in the case of american standard . TPI also will not tell you how many turns it will take to remove the cap since what you also need to know is the length of travel of threads, and the number of starts. A 20 TPI thread would take 20 revolutions to travel 1 inch and thus 20 revolutions to uncap. But if the thread length is only 1/2" it would only take 10 revs. As well, there are the same TPI in a single as a double, triple, quad, etc. But the length of travel is increased, therefore less revs to travel the same distance. So a double start would only need 10 revs to travel 1" 5 for 1/2" etc.

The Platinum Procyon takes less than one cap rotation. The first time I unscrewed it, I thought I had broken it somehow! :-)

This is exactly how i feel 😁
If you start screwing it on with the logo on the other side, it will end up being aligned
David Cudia Yeah, I think so, too :) Start up with the Logo on the backside.
Fascinating!
Pitch is the distance between one thread loop/winding to the next, not the angle.
I was on the same page as Drew when the pitch was being discussed, so no you're not the only one haha great video!

This drives me nuts so i=I found this super interesting :)
I have a Levenger L-Tech 3.0 that's a septuple (7)-start screw. Less than one rotation :D
Thank you, nice video. I was wondering why the Visconti homosapiens looked oily
Should’ve pulled out a Montegrappa Copper Mule as well - to showcase the thickness and the “pitch” you were talking about - I like those threads!
I love my Opus 88 but I hate how long it takes to uncap
So it said Mar. 1 at the beginning. It’s May guys. Y’all are two months behind my dudes.

The more rotations there are, the better I like the pen! It’s always been that way for me. (Now I want that opus!). :)
I'm the opposite. More rotations equals more work.
