I recently filled a hallow aluminum tube with expanda-foamThe tube is about 1.5in in diameterI now want to remove the foam from the tube and don't know howIs there any kinds a chemicals I can use to get it out or will I just have to manually scrape it all out.
a drill bit that size is going to be hard to come byA wood spade bit (if you have them) would be the next best thingjust make sure to clean out a couple inches first that insert spade bit in tube and continue - pulling it out often to keep it cleaned out.
