I am in need of finding a high-capacity ink converter to use in making a bespoke fountain pen for a customer that does Copperplate Script calligraphy and uses an abundance of ink. She is will to consider me making an Eye Dropper one yet more messy and my concern of the grease and possible O-ring I have researched will eliminate leakage concerns. The nib she acquired is a flex 14k Jowo#6 and between purchase and modifications on the nib is around $200. So shoot me some ideas please.

You could try the TWSBI converter.
It is 1.5ml which is almost double the Schmidt K-5 at 0.86ml.
The opening is a standard international size but the outer diameter is larger, so you will have to take this into account.
I heard about this on on the "As the Pen Turns" podcast and have been meaning to order one to play around with it as an option.

Another option is the Pilot CON-70 converter - quite different mouth configuration, I think it holds 1.1ml

I picked up these "Magnum" cartridges because I use my fountain pen all day long at work.
Don't know if it's fancy enough for your application, and having to fill it with a syringe is a little annoying. But that trades all the space taken up by a piston for ink.

You could make the leap to a piston filler. Not easy to make from scratch but possible. Richard Greenwald used to sell a little kit of parts and you did the rest. Since he isn't in business anymore that avenue is closed. There are inexpensive ($4.00 range) piston filler demonstrator pens on the market that could serve as parts for the pen you make.

I practice English calligraphy (copperplate) as well as French, Chancellor and other Renaissance.
For my part, and perhaps you will find a start of a solution there, I use Jinhao 9019, 9016 and 1935 for their high-capacity converter - the same for these three models. Personally by adapting ultra-flexible nibs (Kanwrite and Click, but the FPR adapts to them like others #6).
These converters have a screw thread, which makes them independent of the power supply or the nib block.
If you look at one of my posts on this part of the forum, you will see the solutions that I applied:
Hole in the nib block allowing an entry of the converter while promoting sealing. Obviously enlargement of the converter orifice to 4 mm, which gives a significant flow.
I made an adapter to fit #6 nibs to the block, which allows me to adapt a large number of nibs, even old ones to dip, and feeds of various kinds: in plastic that I can sculpt, in ebonite too, in which I increase the ink supply to about the middle of the nib.
I adapted five fountain pens like that and all of them give me satisfaction, with characters that can go up to 15 mm for the minuscule body.
Afterwards I also adapted fountain pens that could do it with parallel pen cartridges.
If this can be useful to you...
