Things I did different:
Handle is 12" x 1.5"
Head is 3" tall
I adjusted the interior dimensions to accommodate the changes. I started with a piece of nice red oak 3/4" x 3.5" and tried to expand or contract dimensions to cut as little as possible.
Start of glue up. The 2 interior pieces glued to the handle.
Exterior slabs glued on:
Now time for the spoke shave to smooth the faces and round the handle.
I will drill for dowels through and through so it all stays together longer. I am not sure of the finish I think I might just leave it the way it is. All and all I think it was worth the time, 2 nights and money, FREE.
