OK Dale here it is.
Turn the outside
Coat liberally with mineral spirits, go have a cup of coffee or start a second piece while it dries [about 20 minutes]
The mineral spirits will give you a "surface dry" that you can sand with out too much clogging of the sand paper. I usually sand to 320 at this point.
Chuck the bowl and turn the inside.
Coat the inside with mineral spirits so that it is running freely. Turn the rpm's up as high as you dare with the particular piece. Add more mineral spirits to the inside.
The centrifugal force will actually throw the mineral spirits through the wall of the bowl. Stop the process when no more mineral spirits are hitting your shop wall.
Let it dry. Again you have a sand-able surface.
Finish sanding the inside and re-sand the outside to remove the sap and mineral spirits that passed through the wood.
Apply finish.
As I said last night, I have been doing this for 19 years. Working alone down here in Belize before I had the internet I made things up as I went along. With no good sources of dry wood and to impatient by nature to wait I started turning green and stumbled along until I perfected this technique.
