 I have been hearing about spinner bulkhead cracks on the Hartzell propped
 Lancair 320 spinners. Also it is said the cure is to add an additional
 stabilizing bulkhead foreword in the spinner cone. Question is whether there
 is a suitable pre-made stabilizer bulkhead available?  If not, has anyone
 posted a method for making such a bulkhead?
 
 Thanks
