Coal burners, Perhaps the long skinny brush used to clean coffee brewer pipes would be of use. The brush is 24" long with bristles 5" of bristle sticking out from the wire a mere 5/8" (compacts down to 1/4" or less when compressed). The wire is pretty flexible to snake through coffee filler piping. I buy mine through a local business that provides groceries to restaurants. I have also found them at janitorial supply businesses and through a Fuller Brush. It occurs to me that craft supply houses have very long pipe cleaners in various colors that might also work. These pipe cleaners come in standard bristle length, long bristle length, and varied bristle length styles. ~Gary - ready to finish laying track through my tunnel and out over a normal sized trestle http://www.angelfire.com/or/trainguy
