This one is my first functional piston filler pen. I made it almost a year ago, and it is one which I usually write with. Since then, I have tried several designs for the piston, and I have made some other pens which I hope I will show you soon.
As you´ll see, this pen is still black, because that is the material I have more, and to make the plunger work you have to unscrew the blind cap placed at the end of the pen. There you find a buttom which you must turn to fill the pen.
The making of the pieces of the plunger was a pain, but finally I got them. Although this was the very first functional pen, I did not repeat this mechanism because I wanted to do it like the most pens currently have, I mean, without the need of dissasembly any blind cap to turn the plunger, so you just have to turn the end of the pen to actuate the piston, which has been another pain.
This pen has a #6 Jowo nib and the ink column of the tank has 30mm high and 7mm of diameter. I will appreciate your comments and advices, thanks in advance.

Looks good! My first piston filler used this same type of mechanism, i.e. blind cap and knob. Yours looks much better than mine did though! Great job being innovative and trying new things!

Hi Javier - Welcome to IAP from Medina, Ohio!

Looking simply at the first picture, I love the basic shape you have!

You are well beyond my skills already, so I will simply say that I look forward to your future modifications and refinements!

Please keep posting!

Thank you very much for your kind comments, you guys are awesome. And Mark, I don´t think the same than you, I´ve been watching your work and althougt I´m into fountain pens, I can appreciate the fine work you make. I´ll post some other pens I have made

Gerrit, I will try to upload a picture of the plunger dissasembled from the pen tomorrow, but there´s nothing special in it, I mean, there is only a screw with an open thread and its female. The difficult is to make and adjust them by hand

Sorry for the delay, Gerrit, I know I´m late uploading the images you asked me for, but these last two days I´ve been very busy and it was impossible for me to show anything. But as I told you, here they are

That's a seriously wide pitch on that piston. I am envious. the best I've been able to do is an 8tpi quad start thread on my pistons.
