platinum How To Modify Converter For Platinum Pocket Pen

[Hutao]

Hi, I just recently bought a new converter for my old Platinum PKB-2000 which is a Pocket Pen.

My old converter was gone when my dad accidentaly threw it away. Anyway, this topic is just a remake from a2z's old topic.

I'm just gonna make it clearer from the image, because the how to is the same as it was from a2z's old topic.
You can find the original old topic from here: a2z original topic.

As for the how to, I'll rephrase it with my own words:

First of all, the tools needed: Cutting mat(I use Joyko CM-A3, but any cutting mat will do, as long as you have ruler if they don't have built-in ruler like what mine has, mine was bought intially for gunpla, lol), and Cutter(I used Kenko L-500, but any cutter that's not dull will do).

Steps:

First, you must turn the rotating stem on the converter counter-clockwise, so that the plunger go all the way to the other end of the converter.

Second, if you have a cutting mat just like mine(see the picture below), you can just cut through the rotating stem leaving 0,5cm of it.

And voila! You have a converter that fit into your Platinum Pocket Pen.

Note: You can only fill the ink until the plunger rod hit the same length as the rotating stem, but it's still waaaaay better than using a cartridge, isn't it?

Here's the picture to help you imagine and decide the cutting line to the rotating stem.

I hope it helps whoever needed this guide. Cheers!

That's a good idea.  

 

I am generally surprised by how much space is wasted on piston converters.  All brands, although some are more wasteful than others (Lamy and Schmidt).  Why isn't the knob shorter, so that the barrel that holds the ink can be longer?  Of course that would have made your modification for your old pen problematic.

That has been my experience as well. The platinum disposable cartridges are well made and even have a steel ball inside to move the ink around. I use a syringe and refill. But of course, a converter is a better travel solution and it's nice to see a technique to make a converter compatible with the pocket pen format.

Nice tip. Doesn't the rod protrude backwards when you fill in the converter completely?

That's the thing, you can't use the full capacity.
