Lately I've been noticing my blanks are not always square. I get some tiny gaps when I join the barrel to mating parts. Is that an indication of a dull pen mill?
Not sure about a dull mill but more so the method of holding the blank which is not allowing it to remain square to the cutter head and/or the wrong shaft on the mill head.
How are you sharpening your trimmer? You should only hone the back side and not the face (not sure if thats a good explaination) .. trying to hone the face could result in uneven cuts. Check out this thread maybe there is something here that might help

Also, try using a countersink to slightly chamfer the ends of the tubes, or check out the real nice tool one of our members makes for sanding the ends after trimming.
Paul, me too.. Just can't see if the mill is sharp and the pen mill bushing fits inside the tube snug how it would mill uneven...
