"Obstacles de la vie"

So this is my first completed pen this year, not because of any great difficulty although there are a lot of elements, life just got in the way, hence the name.

Walnut, Padauk and Holly, black tulip veneer, black and red pvc accents and black acrylic. I made an option of fountain or refillable roller section.

Thanks David, there's a lot dimension involved as I had to make an acrylic core and finial for the barrel and a similar idea for the cap and sections. The internal for the cores are - barrel is 9.1mm internal diameter to allow for M10 x 1mm thread for the matching section and also allow me to mount on a mandrel for turning and shaping. Cap is 12.3mm internal diameter to allow for a triple M13 x 0.8mm thread ( the threaded collar on the barrel matches this). I generally use Bock #6 nibs and carriers for my fountain pens so threads and sizes are based on and around that. If you need more information I'm happy to make a diagram , may take a day or two though
 
Holy moly! What a beautiful pen!
I have a beginner question, if you don't mind - how did you get the metal ring in between the nib and the section to be there?

Thank you, I use brass tube 1 or 2mm thick, if you look in this image of a section before I've drilled it and applied threads and shape. I cut a step on the end of the section the same as the inner diameter of the tube and then bond it to the section. You need to use carbide tools when turning it down and go a little at a time so you don't get too much heat in the brass ring.

Wow, ok thank you so much! And thank you for including a picture too, that is really helpful. Right now I am just getting started turning kitless pens, but when I've practiced more I'll be giving this a go!
 
That is one of the most beautiful and unique pens that I have seen on this site….,,a gorgeous piece of functional art. Superb handwork. Doc😊

Hello, I have some other questions if you don't mind - where did you get the brass tube and how did you cut it?

I found it on eBay, I mount it in a collet chuck and turn off 1mm rings.
