When I measured the id of rod bearings, I did it with bore gauge then measured gauge with verniers. Then I rechecked that measurement with using only the verniers on the id. I averaged those 2 measurements to get clearances.
I have used the bore gauges before, but it's use wasn't as crucial as it is now and very limited. I can see how the accuracy is difficult to achieve.
Plastigage is next and the final check for rod clearances.
Everything is at same temp in the shop(cold lol), I wonder if it will affect my measurements?
Me my grandson Knox and Knox's new toy cousin. He absolutely loves her. Lol
Thanks again!
