This is the actual hands on approach using a Dotco Die Grinder by shifting hand power and using the part of the carbide on a given area to obtain a desired result.  Notice the flame has a 'belly' in the middle of the carbide which when used with in the bowl area it digs a deeper bowl than an egg with the right amount of taper to the scibe line.
