All this talk about brushes and small diameter tubes got me thinking that I 
had seen what we all needed somewhere.  I pulled out Small Parts Inc. catalog 
and in the 2001 edition, page 424, is list of small nylon bristle brushes.  
Smallest diameter is .020, a bit small for a flue, and largest is .250.  The 
.250 one has a six inch handle so some sort of addition to it might be 
necessary.  Might work for some flues.
