I bought three half log cherry burls at an auction. The logs were cut in
half and the ends were somewhat coated but not very well. I expect they
have been stored like that for some time.

Today I cut them into turning blanks. The newly cut wood measures 14-16%
moisture, compared to 24+ for fresh wood and about 8% for kiln dried in my
basement. So, they are pretty dry, but not bone dry.
A large piece of roughcut 12/4 curly maple I bought at the auction also
measures 14-16%, so it was probably just humid where they were stored.

Do I:
1) rough turn them, dry them, and finish turn them.
2) just finish turn them now
3) let them dry, and then finish turn them
4) something else
