I have Kas' book but I haven't read that far.  But I do have a Datsun drum
and it is actually an aluminum drum with a steel insert for the shoe
contact.  This means the drum will corrode to the axle hub (disimilar
metals, you know) and act fragile when you pull too hard with the wheel
puller to get it off.  Ask me how I know.
