I'm trying to perfect gluing my tubes in by working with transparent acrylic blanks. I'm using 30 minute epoxy, but it seems that nothing I do gets a perfect look. There all always spots where the glue doesn't fill up all the space between tube and blank. I've spent minutes per tube trying to spread the epoxy evenly, but still didn't succeed and it looked not much better than the first quick ones I did with CA glue. Is it even possible, or am I wasting my time? Any tips on how to get this perfect so it doesn't ruin the look of the pen? Should I just embrace the imperfections?
