I'm just about ready to start the sanding process on my first pen and its still a bit thick and not yet at the 1/64th of an inch larger than the bushings as directed on my pen kit. Do you penmakers just "eyeball" the diameter until you think its the right size or are you measuring with calipers? I remember reading something a while ago about including the pen band on the mandrel as you turn so you can check the blank size as you go along...has anybody heard of this? Also, those of you that do a CA/BLO finish....how do you avoid getting CA on your bushings?
