Hi Group, I just got around to building a negative rake scraper. I got a high speed tool steel blank to make it out of. I was wondering how critical the angles that are ground on it are? I was trying for 25* on top and 40* on the bottom. I ended with 21* on top and 47* on the bottom. I tried it out on a bowl that working on and it seem to work pretty good. Still need to make a handle for it though. A friend of mine has a purchased one and the angles on it appear to be the same and centered. Not the best pictures but they will give you some idea. Thanks, Jim
