OK, attempt #2. Up on stands and off stands, start to finish 22 minutes.
A few squirts of PB blaster while he was taking it apart and five whacks with the 4 pounder on the sides of the hat and it was off. I suspect the PB blaster from yesterday had time to work in and made today's removal much easier.
The rear shoes are at rivets and need to be replaced. The hub is a little loose, but not wobbly. We'll replace the shoes to see if that was the source of the dragging, If not, we'll replace the hub.
Lesson learned here (again) is spray the hub the day before you are taking it apart if the hub rust is holding the #$(%&$ rotor in place. And never be without a good 4lb sledge.
Thanks everyone!
