The above Liner started out as a 12½” diameter aluminum circle.  This aluminum circle was deep drawn four times and then in the final pressing operation the end was necked down and thinned out to allow the spinner ( Samtech International ) to spin the bottle to the finished size.  During the spinning operation the performed cup is spun to make the bottle longer and the side walls thinner.  The final operation will spin the open end down to a three quarter inch threaded port.  The finish size of the bottle is 3.900” diameter by 20” long.
