I decided on a twist pen for my first kitless, so I wouldn't have to worry about threads and such. I used a slim transmission and a pair of slim tubes. Aluminum finial and nib, "Alien Blood" PR, Parker refill. I haven't decided on a clip yet. The nib was drilled then epoxied to the tube and the combination was turned between centers.
I did learn that press fit parts don't work so good with a spring loaded refill. The finial works its way out after several uses of the transmission. I weakened the spring considerably and it helped but still isn't perfect. So I will have to incorporate threads somewhere anyway if I make more of this design.
My calipers must have moved between measuring the finial and the barrel.
But as this is just a design test, not a huge deal.
