This is probably the most complicated part I've machined. A friend asked if I could make a shaft coupler that had an internal hex on one end, and an internal involute spline on the other. Since I have a metal shaper, I said I should be able to do that... Of course, I used every other machine in the shop in the process. I ended up cutting the spline on the shaper, but made a broach for the hex end, following the method shown by Clickspring in this video: youtube.com/watch?v=MYI1slVGziU&t=346s
