It's Elm - Always the same rotten trunk
30 cm Large - 20 cm High - Thickness less then 1 cm
it's the first hollow which the thickness it's all the same...
i'm incredible please about that...
becouse i dared,
and it was a success that nothing went wrong..
i Use Bowl Gouge how much how it could be used,
Then Rolly munrow which is superb Tool for Hollow,
i have to thank chuck Vicmarc 120 to keep it strong and balance in its place.
