Making the Piston Shaft

I spent a relatively short evening making the piston shaft. I cut the threads using the treading mode on the lathe.

One unanticipated benefit of the lathe method was that I was able to creep up on the right minor diameter and try the fit for the last few passes until it was just perfect.

I was kind of intimidated by this step at first, but it turns out threading on a lathe is pretty easy.

Edit: Here’s the complete piston. Pretty spiffy eh?|
