From ear to ear its 3.750", so the fancy one piece started out at about 4" round stock. You waste a lot of material machining down the plug to size.
The first one I made was like the fancy one, 4" billet stock. The others I made, the actual plug started out at 2" round stock, then sawed of a 3/8" thick 4" billet for the cap.
Either way is fine, but it's less machining when you start out just above OD size.
