Ovality of cylinders

Discseven, you are correct, helps to know what the other cylinders are doing. Currently we have the ovality specs for the other five. See below.

I think that with these measurements on the cylinders that they are usable as they stand. Still need to add in info for the pistons.

Measurement was done at two points (A and B) 90* out from each other. Both at top and bottom of cylinder to see any differences.
.....| A
B--O

0.04mm is the limit, which is 0.00157". Measurement tool was in inches
Diff limit is negative under limit positive is over limit to the limit

……... TOP…..………… ………..… +/- || ………… BOTTOM ………… +/-
Cyl# A…… B……..Delta… diff limit || A…… B…….. Delta… diff limit
