I have carved the inside of the vessel probably 90%. I have removed wood from the outside so that very little of the vessel is over 30mm. thickness. The vessel now weighs 16kg. I have to get the moisture content down, so the less wood that I have to dry, the better. The ends have been oiled to slow down the drying.I now have it wrapped in plastic and strapped to the kitchen ceiling above the heater so I can sweat the excess moisture out.
