Old Rotring Rapidograph Ink Recommendations

What black ink do you recommend for old Rotring Rapidograph (#1 and 2) pens? They are primarily for drawing on suitable coated paper. Ages ago, before the www had even been conceived, ignorance of finer points of ink was hard to overcome. So I used whatever was available, both for ink and for my paper, and it fortunately worked adequately. I am returning to drawing and want to load them with more care. This ought to open new vistas. I have been sketching some with my daily driver Pelikan with the gold EF nib and Pelikan blue black, re-acquainting myself with drawing rather than writing.

JetPens.com - Rotring Rapidograph Refill - Black - 3 Cartridges - https://www.jetpens.com/Rotring-Rapidograph-Refill-Black-3-Cartridges/pd/8025

Is this kind of what you are looking for or? Are you refilling the cartridges? If so, looks like a pigment based ink. Platinum Carbon Black, De Atramentis Document Black comes to mind

You are obviously knowledgeable. Thanks so much. I also have an old piston fill Koh-i-noor. Any recommendations for a good black or sepia? Same Ink?

I have some vintage ones I found in a thrift store.

I have not yet even tried to clean and use them, as after doing research I found that the specific ink that they are designed to work with is akin to India ink, making cleaning them once they are dried and gunked up a major chore. Inks that work in fountain pens will not work in these, apparently.

Lots of drawing inks work fine in those pens as long as you clean them out every use. Fountain pen inks work fine as long as the paper is sized properly, drawing inks usually contain shellac or something similar to prevent bleed. Best to flush completely as soon as you are finished with them.

I have bad memories of drawing graphs for publications with Rapidographs, I always seemed to have at least one pen clogged all the time. Still have the set in my desk after 40 years.

For those not familiar with this type of pen, they have a hollow tube for a nib with a valve operated by a pin that fits inside the tube. No ink flow until the tube is in contact with the paper and the pin lifts the valve up, very slick design but a real bear to clean if you let drawing ink set up in them. The normal set was six or eight different width "nibs" as I remember.

It is a fountain pen with the typical Rapidograph needle-like point. The piston knob looks like an actual knob rather than the rounded end of the body.

Yeah not sure what ink they take. If you cannot find out you can always try some fountain pen ink and see what it does. It may be too runny, but you have nothing to loose. Besides if you use a benign fountain pen ink like a Parker Quink, Lamy, Waterman, Pilot, they will be easy to clean out if they do not work.

Ever used one like this? Easy to clean and no need to change pens to adjust width. Only problem was the invariable mess.

Now I did find this page on koh-i-noor

My brother has my Dad's drafting set of those pens. Used to make final "master" drawings for blue-print production.
I inherited my father's drafting tools, referred to at USNA as a steam kit. It had compasses, dividers, pens of that sort, and more. I spent countless hours drawing with it. A couple of years ago I passed it on to the next generation of the USN.
