The copper metal spinning blank is worked in this step on a ‘break down mandrel’ that is slightly bigger than the finishing mandrel.  Using compound metal spinning tools (also known as scissors or lever tools) the flat blank is formed into the beginnings of copper tea kettle body.  Using his sense of sight, sound and feel, the spinner extrudes the material over the form.  It takes years of experience to know ‘how far’ the metal can be spun in each pass of the tool without excessively thinning or cracking the shell.  As the metal spinner shapes the copper shell, it work hardens from the stresses of deforming the copper.  In this first stage he works each area of the blank only enough to get it into the proper position, still leaving it soft enough to be spun again in the next step.
