Some months ago I decided I would make a pen inspired in the old safeties from Montblanc, Kaweco and Waterman.
I wanted to make a big size pen using only Ebonite and that would have a self filling mechanism all made by myself.

I have developed the design of the pen and of the filling mechanism with the valuable inputs and help of Pedro Nabais, a Portuguese pen friend aficionado. I want to make a public note thanking Pedro by all his great ideas and precious help.

This is a quite large pen as you can realize by comparing it to a Montblanc 149 and a Delta Dolve Vita Oversize standing next to it in one of the pictures. I wanted to make a pen that was big as the Famous Montblanc 12 or Waterman 20. Turns out I did not make it as big, but almost!! During production I decided to make it a little smaller so it can be comfortable to use during writing.

The clip is inspire in the Soennecken 111 series clip design but it is a "wrapping around cap" one. It is Sterling silver and was hand made by a jeweler according to the design defined by me and Pedro. Pedro had a huge part in the clip development. I really like he outcome.

The pen takes 3,5ml of in and the filling system is based on the Parker's vacumatic system but I have replaced the sac by orings. 10-15 pumps and the pen fills completely and lasts almost a life time.

The pen was all hand made using my lathe and engraved using a CNC engraving machine.
Cap has a 4 start threads. All joints are threaded for easy disassembling in order to perform any needed maintenance on the filling mechanism, like replacing the o-rings or to clean any traces of the last ink color used.
I have used diagonal knurls in the cap top and barrel end to give some texture and break the straight lines of the pen.

It is fitted with a Bock nib.

In the last pictures you can see the filling mechanism and all the pen parts!!

Measurements:


Total length - 150mm
Cap length - 75mm
Barrel length( with nib) - 132mm
Posted length - 180mm
Cap diameter - 16,5mm
Barrel diameter - 14,5mm
Ink capacity - 3,5ml
Nib - Bock steel nib - shoulder-width of 8.4mm and visible nib length of 23mm for an overall nib length of 35mm


The NR I is a limited edition of 4 pens, each one in a different color:
I - all Black, still to be made
II - Ripple brown - my personal pen
III -Ripple green - Offered to Pedro
IV - Ripple Dark brown/Red (still to be made)

Enough about describing, here are the pictures, hope you enjoy and your comments and critics are welcome!!

I would appreciate if you could help me with a small survey and tell me what design you prefer the most and why:

NR I , NR II or 1949

You can find all three here in this forum. Thank you in advance!!

Your Ingenium is a beautiful pen, if a bit larger than I normally like a pen. That clip is stunning!
I think I like nr I best of all, from the pictures. However, I think I would have preferred no engraving on the barrel or cap - if it must be maybe a more flowing script, more in line with the graceful curves of the material itself, and in black, not white! so that it matched more with the pen's elegant design...
But those are minor quibbles. Enjoy the fruits of your craft!

Thank you for you comments! The engravings are painted in Silver colour to match the clip and nib. Engraved on the cap is the brand name and logo, Model number and Serial number sre engraved on the barrel end.

I am using a Roman Letter style font because the brand name is a Latin word.

Very elegant design and colors, sir! I like the size and that they are piston-fill.

This is fascinating, as I have had a similar, but different (ummmm, not as good:) ) design in my head. Very nice!

I just have to ask as I really dont know. How do you keep your ebonite button from coming off of the plunger? I have never made a button filler such as that and it has me puzzled.

It is hold in place by pressure fit. Ebonite has some elasticity and works prety good.
No need to glue.
