Here is a thread from an other site that has lots of information on achieving what you are looking for:

Pay particular attention to the posts by "Zonie" about using lye to achieve the depth and contrast that you are talking about. Zonie is an aeronautical engineer and builds really beautiful stuff. He is very helpful and will answer questions if you send him a PM.

Good luck on the project - that looks like it will be a beautiful stock when finished.
