Spent the day working on the connecting rods.
First was drill the holes for the rod bolts.

Then cut the ends off and tap the threads.

The needle bearings I am using have a rather thin shell so not to squeeze them too tightly with the rod caps I used an expandable reamer and an extra bearing for fit.
Once I had the first rod cap size set the other three were a piece of cake.
