Link to: Setting Up a Scraper Plane
From Walke Moore Tools:
If you’re new to scraper planes or scrapers in general, you may want to read this first.
My Lie-Nielsen #112 scraper plane has become indispensable to me since I purchased it about a year ago. Whether I’m dealing with exotic woods, interlocking grain, or just smoothing a knot with the usual grain reversal surrounding it the scraper plane does it all and I would not be without one at this point. But maintaining a scraper plane can be tricky and unlike hand planes, there isn’t a lot of information out there on how to set them up. Hopefully this will help (so please tell your woodworking nerd friends).
