Bill Moore states that the stroking should be from the smaller diameter (the foot or the tailstock point) toward the larger diameter (the headstock side). The point of contact of the forming tool with the spinning metal should be below center line and the stroke should be from the center to the outside edge. The repetition of the pressure draws the metal down over the male form, causing it to take the shape of the pattern against which it is being spun.
If you're making a piece of art or production pieces, the process is the same. The pattern can be used again and again if one takes care of it and exerts reasonable care in the spinning process. It's amazing how quickly a piece can be formed, trimmed to size, and polished--ready to use in a short time.
