Any advice, especially lathe procedures would be greatly appreciated.

It's a simple boring (both lathe and ho-hum) job.

Chuck it in the 4-jaw with more than 3/8" overhanging. Bore, turn to
o.d., face, cut off a little long.

Mount 3-jaw. Flip the work, and face the other end to get the right
thickness. (index the faced surface against a block to get the piece
square to the axis)

It's a huge, thick piece. There's plenty of meat to chuck both times.
