Hello All,
for cleaning/deburring seat tubes have had good results with this method. Find a wooden dowel ( broom handle ) close in diameter to the seat tube. Tightly wrap 100 grit sandpaper around the dowel until it's just slightly smaller than the tube hole, and use it to clean the inside of the tube by moving it back and forth inside. Blow it out with canned air or clean with a damp rag to get dust/ metal particles out.
