First, I hope I never have to make any more of these. They're a major pain in the ass to make on a manual lathe, especially using 4130. I also did a weld repair on the handle using muggy rod for cast iron.
I started with a profile of the handle and dimensions I wanted. Then I drilled and bored the center of the 1 1/4" diameter handle for the shaft. Then using the DRO I plunged a cutoff tool to the correct depth every 1/4". Then I went back and cleaned up between the plunges with the cutoff tool. The rest of the cleanup and profiling was done with files and emery paper. The shaft was made from a 1/2" X 5" grade 8 bolt. I didn't keep track of the time but I'd bet it took me every bit of 5 hours.
