Tim,
Most of the others have covered what I may have written but I will caution you about using ebonized wood that if the darkening does not go all the way through the inlay you will cry when you flush it and realize the maple shows through. For a project this size you are better off using real ebony and using scarf joints to make the strips seem continuous. This way you will not have to go out and buy long piece of ebony and it will be cheaper then you think, fast, and look better than the maple will.
