Made some progress.
I ordered and received a new cylinder to replace the one I screwed up.
The new method of centering the cylinder body in the four jaw worked beautifully.
I have two identical cylinders within .002”.
They are concentric and true to the bore.
Working with brass is a real pleasure.
Before I go further I need to clean up the castings to get ready for the drilling and tapping operations.
