Here is a small maple HF I just finished. You have to love Maple. It is around 5"dia by 4" high. I used my home made hook tool to return under the lip of the bowl. The opening was only 3/4" green. It ended up around 1" after returning the bowl to true it up. This bowl is turned from scrape I got from a large blank that I cored 5 bowls out of for a friend.
