Now, this is a pin from CNGreen. It is most interesting. I doubt he even saw this.
This is a Trigo pin. The taper has actually started to crack. Again, notice the thin, shiny ring where the contact angle of the pin did not line up to the countersink on the hub adapter. Thankfully, he sent me his hub adapter as well.
This should put to rest the nonsense of outside corners not being stress raisers--this picture states other wise. ANY sharp edge is a potential to cause you grief.
The tape around the pin marks it as coming from CNGreen. (Had to keep all this stuff straight).
The plot thickens...
