Thanks Kenny. On the blue walnut pen, the hole was with CA filled but unfortunately the brass tube was visible anyway. I have drilled and filled other holes in the epoxy with CA and they do end up working well.If your interested you can pop or drill out the air bubble and fill the hole with CA. The only thing is you need to make sure all the dust is out and the hole is spotless before filling. Most places are small enough you don't have to worry about adding pigment. Either way I'd say your off to a great start.
