'46 starter

I am at my wit's end. My '46 Packard starting motor keeps breaking the cast iron nose cone. The flywheel is true, the ring gear on the flywheel has been replaced, the starter has been rebuilt and then I purchased another one from Max Merritt Parts. Both wound up with broken nose cones. I installed a 'kill' switch on the starter to disable it while driving, just to avoid the possibility that it might try to engage when I was at speed. I still broke the cast nose cone. I have NEVER heard of this happening before on any vehicle, unless the timing was way off, causing the motor to buck backwards. My timing is perfect. The car runs like a dream and everything is perfect except for this. I am fresh out of ideas and welcome anyone who can point me in the right direction. It is far too costly for me to keep going on with trial and error. Thanks in advance.
