Moore Pattern Hand Scraping

My take on the mechanics of the Moore (crescent moon) hand scraping stroke. Also cover scraper sharpening tips and marking medium application. Thanks to Wayne Moore for "Foundations of Mechanical Accuracy" which inspired me roughly 40 years ago to start scraping and pursuing accuracy.

"Shop Notes"* by brs_workshop

• Robin's background and experience with scraping
• Showing the basics of the crescent pattern, hand positions and motions
• Scraping with a smaller scraper in a full pattern on a test piece
• Explaining how to sharpen and lap the scraper blade, advice on radii
• Showing the sharpening wheel. These right-angle slow-speed face grinders used to be widely available from every woodworking supplier. Even Harbor Freight sold a version (sometimes called Wet/Dry grinders). However, these now seem unavailable in the U.S. If someone knows why, please share.
