Another Machining Video
 

Here's another neat Video......The First operation is Drilling a 1 1/2" dia hole thru 5" of thickness and then going into a downward Helical cutting program to put a 5" dia thru the part, then it gets a counterbore pocket for Bearings.........this is just roughing the part
