Gearbox Shaft for Well Drilling Part 1

This video will be a short series on the final machining for a shaft I started years ago. It goes into a gearbox used for drill water wells. This was a spare I started a while back and now it's time to get it finished up. The machining will include steady rest work, facing, turning, face grooving, threading, internal square threads, and milling keyways.
Follow along as we turn this piece of 4140 into a finished part.
