Pic 1 = Size at the top of cylinder. this gauge reads in tenth's. Meaning each increment is .0001" or one ten thousandth of an inch. That is 1/30'th the thickness of my hair. One revolution around this gauge is .010".

Pic 2 = Size in middle of cylinder.

Pic 3 = Size at bottom of cylinder.

Now I let it cool down. It will shrink up a little bit. Tomorrow I will Touch it up and get it back to zero, then plateau hone it. A plateau hone is a bristle brush, impregnated with very fine gritty powder that breaks the peaks off the cross hatch, or plateau's them. This way the rings don't have to do it, and the rings will seat faster and easier, and last longer. Pics of final job to come.
