OK so I'm back looking for help.
The Mrs has now suggested that she would like me to make her a square oak block with a bowl carve in to it so she can put her jewellery in at night.
I gave her a breakfast bowl (which she chucked at me.... it missed).
Now I really do not know where to start on this ........
which bit to use.
what tool path to set.
I have tried but all I get is a round hole with flat sides....

Any ideas ......
