ca glue

I am very new to pen turning, I have only turned one pen so far, I've got about $100.00 worth of products coming mail order tomorrow.:biggrin: Here's my problem: I turned a Tycoon pen, used purple heart, which after I had the blanks cut and tubes glued in I was told purple heart doesn't...

What can I place a nozzle stopped up with CA into to dissolve the glue? I used to do this, but cannot remember what it was.

I am having some issues with failures on tubes glued in using CA glue... I take the tubes and rough them using 120 gift paper (on the lathe) and then put liberal amounts of CA glue on the tube on at least two sides... Turning the tube as it is being inserted to be sure to spread the glue...
