I finished the bore in piston pin end to day. Plus I put the face plate on the lathe with the fixture for boring the big end of the rod. But first have cut the bottom of the rod at the center line of the bore in the big end. Then drill the bolt holes. Will drill the bolt holes first. Then bolt it back together.

The 4 picture is the boring head for the finish bore.
