Thanks for the info

nobody fucking asked you gerald

joey willians did you even watch the video. The guy asked

Check out amazing artists like Artem Grigoryev. He use these kinds of pen. and so are so many drawing artists.

That’s great!

Hello I just bought one It seems my ink is also old How did you get to use yours? Did you buy another ink?

@@nanayaafrimpomaadonkor6603 Yes, I bought a new bottle of Rotring ink because the old stuff I had looked nasty and I didn't want to clog the pens up again. They work ok! 😊

But is your ink waterproof to allow for watercolouring over it? If so, what brand is your ink, would love to get some of that. The Ink I have seems to have shellac in it and clogs the tiny 0.10 nibs.

I think my ink is waterproof. I use Sailor Jentle Ink, which is my favourite black ink. Works really well with my rotring and hasn't dried up at all.

Generally fountain pen ink is not waterproof except for pigmented fountain pen inks such as sailor storia and nano inks, there is also some noodlers inks which waterproof although some of them are water resistant which will partial "blur?" away

+daisy3690 Thanks 😀

I sooo agree....he is so simple and suchh a studdd!!

Thanks :-)

Eileen Goldenberg just curious why rOting could not simply make 1 type pen instead of two that would take BOTH cartridges and a refillable converter? If you are new to this it can be confusing.

@@charlesjacques750 Because Isograph is gravity action, and Rapidograph is capillary action. The mechanisms are different.

I recently found my set from my university days and plan to start using them again. Nostalgia indeed!

Welcome 😁

+VeggeMight Thanks 😀

found mine after 20 years

How is this combo for drawing doodles .35 and .70? Can you use fountain pen ink or only their brand?

Thanks :-)

That's great. Good to see they are so lasting.

s monzon it's amazing to think that a pen could last long enough to be an inheritable item. I think that speaks masses for the value and quality of these pens :)

If they are pristine, they are probably NOT worn out. You have to hold the pens perpendicular to your drawing surface to get the ink flowing. If the nib is clogged with India ink you can probably unglue it by sticking the nib end in 70% pure isopropyl rubbing alcohol for about a week or so).. Be careful with the stuff, it is volatile and stinks. I would cover the whole thing with saran wrap to keep the isopropyl from evaporating. I use it and have no problems with it melting any of the plastic parts of the pens...If your grandfather's pens have the old fashioned plunger to refill (instead of the replaceable plastic cartridges, I think you have a collector's item, there! These pens were designed to last a lifetime and then some! Enjoy! In the "olden days" our draftsmen used to empty out their pens every Friday after work and rinse them in clear water then stand them in an ultrasonic machine that vibrated out all the bits of dried shellac. The process took all weekend, and on Monday mornings their pens were ready to use again! It was quite a process keeping those things clean. After the invention and widespread use of the cad computer run drafting programs these pens become collectors' items. I retained mine from Engineering school! Lucky me! Love them and use them for sketching. Luckily for us, now a days there's fast drying waterproof ink with anti-clogging agents in them. But these pens still need cleaning about once a month or so.

Bestbrushstroke Bestbrushstroke sorry, English is not my first language! what I meant is, The label is mostly worn out, however, the tips are still working perfectly. my grandpa taught me how to use them, they had to clean them quite often at his workplace. Thanks for the info!

Enjoy your pens...my labels wore out long ago, too, and the pens are still working perfectly after over 40 years.... And they are a pleasure to use.

Thanks ヾ(⌐■_■)ノ♪

The Isograph is easier to dismantle and clean so I'll recommend that. Whether it clogs or not I think depends on the cap, and the Isograph turning cap looks good enough. I won't worry about clogging unless you use it every few months. And if that's the case, it's better to just clean the pen and store it away until the next use. I do that for pens I don't use for more than a week. Anyway, with the Rotring Cleaning Liquid, it's quite easy to remove clogs.

Thank you! I really enjoy your channel, great job!

Both are problematic, because both work on the same concept. A wire running through a hollow shaft with ink flowing inside that same hollow shaft with the wire. So a lot depends on your ink. There are inks with retarders in that will help it from clogging. But if you use ink pens intermittently you may be better off to use disposables, otherwise you will be spending more time cleaning these pens and wasting ink than actually using them, unless you use regular fountain pen inks that are not India ink and have no shellac in them. India ink have a type of shellac in them to make the ink waterproof, from what they told me at the store. And it is this shellac that dries, causing the steel wire to stick to the inside of the hollow steel shaft. I ruined a 0.1 nib by pulling the plunger out but the steel wire was stuck to the inside of the hollow shaft thanks to the shellac and the wire pulled out of the plastic plunger part.

Oh yeah. I forgot to mention that in the video :-P

+The_Howler Thanks for your insight 😁

Solid advice. I think you have just solved a few of my personal frustrations. Thanks

There are more pens out there than one can imagine. \ (•◡•) / lol

I didn't know there's warranty 😅

Teoh Yi Chie ahah me neither, just discovered while looking at caring instructions on the website! Not sure why you would use it, though!

+Vika Generally speaking, if the ink dries up and leave dust bits around the opening and cap, avoid using that ink in fountain pens.

Yeah, the lines break often when used in non-vertical angles.

sweet, will you recommend them for artists?

Martin_HUN That's great, I bet you know these pens very well. How much time it's safe to let the ink in them? For example for everyday regular use, it's enough if clean them out only at the weekends?

This is also what's being required for us to use (as an Architectural student) in my country for manual architectural drawings. :) Specifically the isographs.

+Vicente Bécquer As for my experience with them and from people I know that have been using them for a long time, you don't really have to always completely clean them as long as you regularly use them. Just make sure you don't let them sitting around unused for a really long time of else the ink in them will dry out. But its also nice to clean them from time to time even if you're already always using them. :)

Martin_HUN I think it's great that you're following the footsteps of your dad and becoming engineer, he must be proud of you 😊

Not sure about that Rotring Ink in Pentel Brush Pen. It might work. Anyway, it's not too expensive to replace the brush pen if it's clogged too badly.

If you use Rotring ink, yes. That ink is waterproof when dry.

+Vishal Vora These technical pens are meant to be used mostly in vertical position so may not be comfortable for use with handwriting positions.

Teoh Yi Chie thanks. What about the pigma micron?

Most technical pens are designed to be used vertically. If you use them on the side, one side of the felt tip will wear out, (such tips wear out quite fast), and it will be difficult to write with them. Just for for normal writing pens for writing instead. I suggest the Uniball Eye, Uniball Vision, Uniball Air and Uniball Signo Gelstick (all waterproof). Or just get a cheap fountain pen such as Lamy Safari.

Thanks again. I picked up a Pigma Micron 0.4 today. Pretty happy and it was good value. Yes the uniball pens you have suggested are good. I also like the Pilot V5.

You probably can. Just clean it out when you don't intend to use the pen for a long period of time.

You can try. Noodler's ink don't usually clog. With the ink bottles that I have, I've never seen them dry into black dust bits unlike other pigmented ink so I suppose Noodlers should be save. Just get one bottle to try before getting so many bottles.

I have the noodler´s ink , I´m going to buy steadler Isographs and try with one .Thanks Teoh

You can use the Rotring cleaning fluid to give it a try kzfaq.info/get/bejne/bpOei6x5vrXIZX0.html

I like Pelikan M200 Fine nib

+Denver Naicker Not sure how how the refills cost. But it is more economical to get the bottle Rotring ink to refill

I don't have the exact answer on how long you can use it before cleaning. Probably a month or two. As long as you use it often, the ink keeps flowing and should not clog. Check out this video I made on cleaning pens kzfaq.info/get/bejne/i5embMWdnKuoZ2Q.html

Thanks a lot.

You mean that really thin “needle”? That’s to push the part that’s holding it up to let the ink flow. That part will block ink flow when you are not drawing, that’s why the pen does not leak

Yes. Rotring has a compass that you can use along with the isographs.

+Manna Manna Check if the pin in the tip is moving. If not then the it might be clogged. Just get the Rotring cleaning fluid to soak the tip overnight.

Same performance but Rotring has larger ink converter

Yes you can. Because of the way the tips are designed, you can't draw very quickly or the ink won't be able to catch up.

Teoh Yi Chie Thanks, I was looking in for this kind of pen. I am thinking of getting one

No, only when I don't use them for more than a week.

I've not used staedler before so I'm not sure.

Is there a needle in the pen tip? Keep tapping the pen tip on paper to move that and hopefully the ink will flow

Yes

I'm not sure if this can be considered India ink. Other options would be Platinum Carbon Black, Sailor Kiwa Guro, Noodler's Bulletproof Black, De Atramentis. They waterproof when dry, depending on the paper.

Teoh Yi Chie thank you. if this is indelible that's all I want but I guess it is not.

You could try Pelikan Fount India ink, it's an India ink adapted for fountain pens (no shellac, less pigment, so in that regard it is probably similar to the other pigmented fountain pen inks). I use it, but have found that it works best on pens with tight caps. It works great in my TWSBI 580 with a screw cap, on my fountain pens with push on caps it's seems to dry in the nib and cause hard starts (however it is easy enough to clean).

Yes, waterproof

+Liza Garcia It's waterproof.

+Denver Naicker I don't think so

+Bestbrushstroke You just hold it vertically?

Yes, it must be held vertically to the paper surface because all parts of the tiny cylinder at the tip must be in contact with the paper in order for the water to slide down the cylinder onto the paper...this is due to the property of water surface tension. In this case, however, the "water" is the ink.

Yes, just hold it vertically. I use drafting pens to draw with all the time. There are only 3 pitfalls to using them....(a) they are not pressure sensitive, but that is overcome by switching to a slightly larger "nib" or tip. It takes a wee bit of practice drawing with the pen held vertically, but after a while it will become second nature. (b) if I pause drawing for maybe 20-30 seconds the ink I use begins to dry up in the tip and the pen needs a bit of shaking to get the ink to resume flowing and (c) if pens are not used for an extended period of time (week or so) the ink begins to dry inside the pen! and the pens have to be disassembled for cleaning. But I love the economy of refilling and the fact that I will not be throwing away a perfectly good "housing" ....that that plastic and stainless steel that is used in making a single disposable pen...such a waste of our natural resources and it clogs our ecosystems with needless trash.

Best to use Rotring ink, or fountain pen inks.

Ok ..thnkq so mch ...

Rotring ink

It's here kzfaq.info/get/bejne/jtJolNWbxLaniX0.html

Thank you, it's very good. I couldn't find where the needle for filling up the rapidograph.

@@juljos9343 Just search "blunt needle and syringe" on Amazon or eBay

Thank you

Something is stuck in the tip

@@teohyc umm i checked I don't think so maybe it needs to be cleaned up

That ink should work.

It's a metal tip. How do you wear them out O_o"

I mean the felt tips so I'm gonna buy metal tips from now on lol. Thank you for answering, few youtubers answer their followers

+Trey Herrera I only clean when I have no intention of using the pen for more than one week.

sí

It's probably better to get a new pen instead. At least you can use the spare parts from the old pen.
