Heres the ferrule I used. I drilled out the thread so it will sit straight in the hole. You can just see the stepped section off the ferrule poking out through the other side.

I can see that you drilled, etc. Also that the finish is changed, but can you give more detail as to what all you did to it? Much appreciated!

After having shaved off what I wanted I sanded it smooth then primed and top coated it using normal spray paint in satin black.

Those carbon jockeys look great. I'm going to get some when my KCNC ones wear out.
