I then made two cuts on opposite sides of one end of the dowel rod, to bring it to an end, looking like an "A" frame from the side. (C)
I then did the same on the remaining sides, to square off the end, bringing it to a point. (D) All the cuts were pretty rough, but like I said, its just a starting point from which we'll bevel it down more later. These cuts also begin to dictate the taper the tool will have. You're basically roughing in the tools shape.
*Edit: You may even want to simply put the sanding drum on the Dremmel and start shaping it from the get-go. But its up to you.
