Chris: The US mil practice for this stack would not use a crinkle washer at the bottom of the stack. The top crinkle washer (mil would prefer a split ring lockwasher) should be enough to provide the axial compression loading on the stack. The baseplate-to-solder terminal interface should be smooth, clean and conductive, hence no crinkle washer needed to cut into the surfaces. Also, the crinkle points are relative small points of contact, so a heavy fault current might melt the tiny points.
