I have used the acetone process on several stocks with god results. However I was in a musical instrument repair shop where they fix and refinish a lot of stringed instruments i.e. violins, cello, stand up bass. They were abhorred that I would soak a fine piece of wood in acetone. They use ozone heat lamps to draw out the oil saying they would not introduce any other substance in case it warped the wood or altered the tone of the instrument. They offered to do one of my gun stocks but I haven't taken them up on it yet.
