Negative rake scrapers *PIC*

john lucas
If you want a really good easy tool to use for bowl interiors make yourself a negative rake scraper. I bought this scraper blank from Doug Thompson and ground the tip into a negative rake with both angles being the same. To raise a burr I just run it across the grinder with my Robo Rest set for 45 degrees. When the burr gets dull which happens pretty quickly you simply flip the tool over, run it across the grinder and get back to work. I don't even shut the grinder off. This tool is much less grabby than other scrapers, takes just seconds to put a fresh burr on. It also does a fabulous job of shear scraping.
