Brad,
Just my humble opinion, but 80, 150, 220 and stop. Walnut and cherry are too coarse grained to benefit from finer sanding and if you polish hard maple down to 300 or 400 it will not soak up much of anything like stain or finish. Also, use a coarse file to get the rasp marks out or you will be sanding for a week. Thanks for listening.
