Finished halfshaft collar in place.

I decided there was too much play between the axle halfshafts and the differential extensions, so I made collars with the precise inner diameter and length necessary to remove all play. I was pleased that I could make them so precisely, even on my old beat-up lathe, that they made an almost airtight seal. I’m showing many of the steps below as a reminder of just how many operations go into making even the simplest-looking parts.
