Piston Filler V.2

[jalbert]

For those interested, here is the second version of my piston fill design that I have been messing around with. I tried to correct some of the flaws my last one had, mainly the material of the plunger. I used Ebonite for the plunger this time, and used aluminum for the threaded connector. I also put a clip on it for no better reason than the fact that I enjoy clips. I also cut room to put an o-ring between the section threads and the internal threads to seal the pen off from any ink leaks.

 

I still would like to find a coarser thread for the piston mechanism so it doesn't take so darn long to fill, so I am in the process of learning to cut threads on my metal lathe (a whole new endeavor in itself). Also I realized how ridiculously small the cap threads and section looks in relation to the overall diameter of the pen, so once I can figure this whole thread cutting thing out, I will increase the diameter of the cap threads and section. Thanks to the suggestion of Fountainpagan, I'm also planning to switch over to a #6 nib. Eventually I'd like to try some embellishments like metal bands and whatnot, as well as make a wooden version. Let me just get the engineering kinks out of this one first

Beautiful looking pen, great job.

[jalbert]

Thank you!

You go fast, John.

 

Congratularions on this second version.

Again, I don't like the acrylic but the piston looks stunning and the pen's shape is very nice.

 

Keep on

Swirl hater It's ok, I am quickly becoming less fond of swirl pattern acrylics too.

Well done! It looks great. Is the weight of the pen thrown off by the weight of the aluminum mechanism? I wonder if an entirely acrylic mechanism is possible with your design.

Thanks! I don't think the weight of the aluminum amounts to much, or at least it doesn't seem unbalanced in my hand. I would weigh the mechanism for you, except I just got done putting the pen back together after lubing the mechanism and have it all inked up

Ahh, okay. If it doesn't throw the balance off, then might as well stick aluminum for mechanism. It looks fantastic!

It looks great and it's good to watch your progress.

Thanks! Glad to have you following my progress!
