ok so i cut out to piece of wood and then cut out the board with the same line graph and when i go to put the 2 together the it dosent line up right
there must by way too much flex in your machine.
I assume the line piece is supposed to be consistent in width. Just from the pics it is way off.
So i’d say get your machine tuned properly first.
I concur, I would think the white line dont align due to the inconsistent width of the red wood due to that.
If you are cutting the walnut stripped board right through, then this video might be applicable to you.
If you are doing an inlay, then I would follow the suggestions already offered above.
The wood inlay is wider than the bit used for the curved cut, thus your wood is ‘stacked’ instead of being lined up.
I cut a lot of segmented pens and bowls. It is key that the wood removed is exactly the same as the new wood or inlay that is put in its place
