I started to make all of the Titanium Shafts by cutting all the parts to length. I then sent the cut lengths to D&D Grinding to have the OD centerless ground for a perfect fit with my bearings and gears.

I then used the Wire EDM to cut the setscrew and timing flats.

This picture shows some finished shafts and Axles.

This picture shows the drive line shafts timing slot freshly cut.
