This is the way I create a finished bowl from a wet blank.
I am not saying it is the best way or they only way what I am saying this is my way.

About a year ago i bought the butt of a storm damaged Beech tree that had been recently felled.I had it planked by a local tree surgeon who did it with a chainsaw,
Because there was so much wood there was no chance i was going to be able to rough turn all of it before it started to split,Some I cut up into usable pieces and roughed out a lot of Hollow forms and bowls.The rest i wrapped completely in cling film.
This is an example of the  cling filmed square blank that has been stored like this for over a year
As you can see it is now well spalted and soaking wet.
A lot of the water that was in the wood has migrated to the outside and has formed a jelly like substance.

This pic shows what the wood is like after the film is removed soaking wet and spalted

As you can see here the wood is looking quite dry inside.
For safety when ever I use the bandsaw i keep the blade guide as close to the wood as possible
Next i drill the rounded blank ready to take a screw chuck.
Note the tape on the drill bit to show me how deep to go.
Next the blank is mounted on the lathe with the tailstock brought up for added safety until the blank is balanced.
I am roughing the blank down with a 1/2" long grind bowl gouge with pull cuts.

The blank is roughed down and a spigot made.At this stage the spigot needs to be over sized and the centre marked this is important because at a later date we will be mounting the rough turned bowl between a jam chuck and the tailstock.
At that stage we will be tidying up the spigot and making it the exact size.
In this next pic you will see a handy little jig that i use for sizing the spigot it is made from poly carb and makes sure you spigot is always the optimum size.
