Default Tube Polishing, Cont'd

This pictures show the before and after. The first pic is the inlet after cleaning with the eye-hook thing. Note the thickness of the lip and how square it is. The surface feels rough.

The second and third pics show the results of grinding and the flapper. The pics were taken before cleaning the tubes out with the eye-hook, clean towel sections and lacquer thinner. I'll clean them again and blow them out to ensure not grit gets sucked into the engine.

The texture is really exaggerated in the pics. Might be the lighting or smearing of the metal. (Check the bits on the grinders) It's a little "dimply" but very smooth. The third pic shows the inside and you can see the flapper has cleaned up the tube.

The tube inlet is about 1/2 as thick after the grinding and is rounded. The thinner lip blends smoothly with the rest of the tube about 2" in.
