Hi Haggy
I to have been playing around with CA finish but not on pens. I apply the CA along the grain without the lathe spinning, I then quickly spin up the lathe and apply the BLO, I then let this stand for a few minutes re-spin the lathe and wipe of the BLO and then leave the work for around another 5 minutes before sanding with 600 grit, sanding until smooth. Then I repeat the process half a dozen times.
On the last two sandings I also go over the work with a very fine wire wool and on the final coat once I've used the 600 grit and the wire wool I'll give the work 2 or 3 coats of burnishing cream and that seems to work for me.
I did try applying the CA at first while the lathe was spinning but this left rings.
A lot of pen turners apply the CA with the lathe spinning and sand to 12000 grit wet and dry and then use burnishing cream, T-Cut or Brasso. They apply around 20 coats of CA. I have not yet applied this many coats to anything that I have done but plan to try it the next time I use CA as a finish.
There's a couple of articles on my site about CA finish one of which is written by Alan Currans who is an accomplish pen turner. His article is worth the read
