I was rushing.
To be truthful, I had rushed the whole bowl. I had stolen an hour from a busy day, and there would be hell to pay if it did not get back to the chores. As Thoreau put it, I had crept away from the family, "to spend borrowed or stolen time, robbing your creditors of an hour." As a result, i did not remove as much as I normally do from the base core, so there was a lot to axe off at the end.
I suppose I could have glued the base back on. Few if any would have noticed. But I decided to leave it alone, to smooth up the jagged edges and put it into circulation in my own house-- an ode to patience.
