The first thing you should have done was to make sure your replacement ebony piece is only slight larger than it needs to be when finished before you glue it on so that there is less wood to remove after you have it glued. When working with bow frogs, a small vice with leather or rubber jaw covers is helpful to hold the frog securely in a position so that you can work on the damaged area. I frequently grind down a small piece of thin wood scraper steel to the curvature needed in the area of the frog I'm working on. Then slowly and carefully scrape off the excess wood. Finish with 600 wet and dry sandpaper.
