SHARPER SCRAPERS
I like to keep my super scrapers nice and sharp. Here’s an easy little way to touch them up. I squared up a piece of scrap steel in my mill and drilled the hole in the same setup so it’s nice and square. I drilled the hole just under the .375 tool post size for my boring bar diamond lap, then honed it to size for a nice tight slip fit. Put the fixture on the post, set the scraper on the diamond lap so it’s sitting flat, then tighten the clamp. Sweep it back and forth with the wheel running a few times and check your edge. Doesn’t take long and they’ll scrape like new again!
