I didn't do too much today. I just unclamped the fractured board and took a look at it. That is really seriously broken.
This One Broke Right Proper
Here is another view of the broken part.

You can see in the photo below that the board has broken in three places. I think that maybe it was a bad board.
Bad Board
That was it for today. I have to make some more changes to my setup and procedures. I think that one of the most important steps is to choose the right boards. I am buying these off the shelf at the Big Box lumber store, so I don't have the ability to cut them myself and make them "right".
