pilot 78G - Kai

Pilot Tank

Today's pen of interest: The pilot tank. It uses the same nib as the pilot 78G, same feed too.

of course it writes as well as that legendary pen but it comes with a larger capacity.

The interesting part of this pen, it is an Eyedropper. One observation about pilot tank as an eyedropper: it doesn't burp at temperature difference and low volume. And its not due to the feed. The key is that sponge like material at its end.

Looks like pilot did have a quick fix for ED less that troublesome VAC type contraption that some other Japanese maker invented.

and if you want to drastically increase its volume, just remove that sponge like material. It does pose a problem when cleaning the pen with that device. cleaning can take.....forever :p

Of course, if you really want to use a converter, it can be converted to a converter based pen.

 1) it is a dropper type. the volume is quite big already, but it can be stretched further. there is a black plastic thing in the body of the pen, remove it, and you get roughly 2.5cm more of the body's volume. it doesn't leak even if you remove it since the plastic does not have any holes.

2). If you want it to use a con20 or con50(con70's diameter is too big, or you want to use a cartridge, just remove that rubber thing from the pen body. the converter can be inserted. there is no leakages as well.

International cap for international cartridges

well, I have demonstrated that the daiso international cartridges is resealable and reusable. some people were confused, but others probably felt that it is too difficult. a universal cap is more convenient. a reusable cap. cheap and good.

Why not? :)

I have finally managed to find the cheap, good and perfect match item for this contraption. Costs next to nothing, helps save the earth, and save yourself.

using a spent ink from zebra..., i don't even remember when i got this pen, nor have any recollection of using this pen, anyhow it was lying on my table as resource, and it tried. it works.

so to make it, just follow the pictures in number. it is easy, so very easy. please at least read step 4. :p

Hopefully i have solved this problem of reusing cartridges in the most simplest way. Am I the first ? haha :) at least i have gotten a generic solution before i close my eyes.

1) the item
 
 2) cut a piece out.
 
 3) test fit. it should be 2mm above the mouth of the cartridge. do not apply silicon grease. it should fit perfectly.
 
4) now this is critical, with the cap still in, hot glue the cap. force some hot glue into the mouth so that it forms a spike. this spike will ensure there is no leakage from the cartridge. it forms the first level of defense. 
 5) once the glue cools, remove the cover.
 
 6) the internal will have a spike.
 
 7) testing with some diluted ink
 

8) close examination.
