This post is several years of but still relevant today. I have changed my technique very little, mostly that I don’t scrape so much but use a flat sanding block to level. Sometimes though, the the best way to get rid of a dimple or blemish is by scraping. I also, at the time, tried to keep it simple as most builders won’t have some of the equipment that I do. This will yield great results for the beginner guitar builder.
