I need to put a smooth finish on the inside of some aluminum tube. 1"

tried that with this. It doesn't need to be precise, just smooth. I
want to round off the weld seam (not to bad to begin with) and make it
fairly shiny inside. Flap wheels? Buffing wheel with a "course"
substitute for rouge? Other?








I think I may have seen aluminium tube with a weld seam but rarely, the
stuff I normally get in the size range you mention is extruded so no weld
seam. I there a reason why you can't get what you need without the seam.

The seam really is not a major issue. The over all smoothness of the
interior bore is what's important.


Why not just use the cylinder hones, that you mentioned, with kerosene
flood cooling/lube. Should keep the stones clean.
