I would talk to the barrel maker and see what they advise.

Good luck, Tom

It will be interesting to set it up on centers and turn it with indicatorson both ends and the middle. I would try this after putting it in the freezer for an hour, room temperature and put it in hot water,120 degrees). Make index reference marks on the barrel with a magic marker. Write down the numbers and let us know what you find out.
