Thanks for the welcome!
This is the part I am referring to which I call the cage. The arrow points to the edge I am concerned with, one edge (pictured) is square while the other has an internal chamfer. Does the chamfered edge face the axle shaft or does it face the tranny hub? It looks like I can see the chamfer on your finished axle prior to grease telling me you put the chamfer on the tranny side of the joint.
Thanks
