Hi Brian,
     Something didn't sound right about sandwiching ANYTHING between the
     prop flange and the drive flange, so I went out to my workshop and
     looked at my Hartzel props. Sure enough the spinner bulkhead is
attached
     to the OD (outside diameter) of the prop flange. Its an elaborate setup
     but, the bottom line is there is DIRECT CONTACT of the prop flange and
     the drive flange, no bulkhead, no RTV, no aluminum disks, no carbon
     fiber or fiberglass. I have 2 props --a 2 blade & a 3 blade-- both are
     done the same. Hope this helps.       Dave M

Hi Brian,
Photo would not show much. Take a look at the attached sketch. It's not
to scale but all the parts are there. If you need sizes or more info
just shout.    Dave M
