Well, if you really like the wood and the eventual design is ingrained in your mind, you could cover it with a layer of thin AC glue. This will harden the outside, as you cut through the layer of glue, add another layer.
You say you added more screws. How many did you start with and how many did you go to? (I always try to use all of the holes) and bringing up the tailstock was a good move. I do that as I hate having wood bash me in the face or fly by!
God and family, the rest is icing on the cake.
I'm so far behind, I think I'm in first place.
