Thanks Jim, Steve, George and John.  

I did not weigh it before after turning and before I gave it away but it was pretty heavy -- probably at least 3 pounds finished.  Southern live oak is pretty heavy as it is one of the densest woods that grows native in the US.  This particular large chunk came from a tree that my neighbor had removed a few years ago.  I sliced it in half immediately after I got it to reduce the cracking as it dried.  That tree was probably over 2 feet across at the base, though I think that this came from one of the smaller branches.  I recently milled the other half of the chunk into boards for other uses.
