Depth problem with wood thickness

Ran I to an issue yesterday with my v carve.
The fontni picked had some fine lines to it.
The thickness of my wood measured .466
My depth cut was .2 using a 90 degree bit.
On some of the fine lines in the fonts it did not carve.
My guess is that the thickness of the wood in that area was different then the thickness I put in.
Is there a way to compensate for variations in the thickness of the wood to keep this from happening again? I know that every piece of wood will not be perfect.

I would consider a thickness sander if you do a lot of this kind of stuff. Most commercially sold wood isn’t flat. It may be warped or even have snipe in it.

Any time you want to do a V-carve with fine detail, I’d recommend running a facing operation.
