Al, you are the only personage who knows what you fancy making from it so only the broadest of suggestions are possible from a distance. here comes my three penn'orth….
Start by deciding if you are, in fact, experienced enough to work on such an out of ballance piece where the tool will be hang gliding through air as much as it is cutting timber.
If you are still confident saw away as much unwanted wood as poss.
mount the remainder between centres.
with slow speed and whisper-light cuts organise a means of holding the piece in a chuck in the best orientation
for your requirements
cut away all timber that doesn't look like your intended project
All the best with it
