[Dr. Curve]

Thanks for the spelling correction JC. The correct word is "Chamfer" and means (among other things) "to cut or reduce an angle, corner, or arris; to bevel" more generally, "The surface formed by cutting away the arris, or angle, formed by two faces of a piece of timber, stone, metal, ect."

Yes, you are right. Don't glass bead anything and then not clean it. I glass bead the skirts of pistons lightly to reduce friction and to help retain oil slightly in that area. The dimples that form can not be seen with the naked eye, but are there. Less metal contacts the cylinder wall and oil molecules rest in the bead formed dimples.

While on this again. No, you would not use teflon coated skirts with our new plasma coated cylinders but they are great in iron bore engines.

You, Jeff, may wish not to use bead blasting any where. In the case of piston skirts however, it has been used by many. Just be sure to clean up after yourself. Thanks for the correction of my unclear spelling.
