Ok, magic marked the edge again, and used 45 degree x strokes, and same with a swoop. (as in the shavelibrary)
The middle is touching the stone, just a little but touching so OK.
However on one side the toe is not touching at all, regardless of the stroke.
As Gssixgun advised I put on 2 layers of tape. No difference. Just to see what happens, 3 layer of tape, no difference ...
I'm getting the feeling I should put this Dovo aside and send it over to a pro :-(
