9.5" Inch 4140 Gearbox Shaft Part 1 (30:51)

First of a short series of videos about machining a 9 1/2" gearbox shaft. This shaft is very similar to my past Heavy Metal Machining series, so I try and give you guys some different angles, and information I may not have shown before. In this video we get the ends centered, set up in the Pacemaker and begin roughing the shaft down. I have some pretty nice 1/2" metal removal cuts getting the ends turned down.
