The first job is to drill the hole through the centre.
With a 4 jaw chuck, mount the block on a centre lathe and drill a hole with a centre drill.
Then use progressively larger drills to enlarge the hole.
and a boring bar to clean and open the hole to the finished diameter.
Then back to the milling machine to mill down to the finished width and chamfer the corners.
more to follow...
