I like using my lathe to make pens for m and to offer to some family and friends, here is one of my last creations.
INGENIVM 1949 was created to be offered to my father on his birthday, hence the 1949 number given to the pen as is his birth year.
The pen was all made using black and ripple brown ebonite, even the rings. The filling mechanism is very similar with the one used by Parker Vacumatics but does not use the diaphragm, instead I used orings to create the downstroke and upstroke pressure that fills the pen. It takes 2ml of ink, quite enough for long writing periods.
Its a fat pen with 15mm in cap and 13,6mm in the barrel. I have installed a Conklin steel nib made by Bock with shoulder-width of 8.4mm and visible nib length 23mm for an overall nib length of 35mm , total length posted is 13,5 cm
The pen was later engraved with the INGENIVM brand logo (Portuguese cross), model number and production year. Engraving was done using a CNC engraving mill but the pen was entirely made by hand using my lathe. No taps or dies are used to make the threads. Cap thread is a 4 entrance thread to make screwing and unscrewing faster and more comfortable.
Hope to have some feedback on this from the forum!!
