Part 1: Filing the Edge.
Christopher Schwarz, Editor, Popular Woodworking (PW) magazine, does a terrific job in this session. He is entertaining, and has an uncanny ability to convey his message accurately and succinctly. I split this session into three parts, for easier viewing. This is the high-resolution video (as high as I can get with an old video camera).
This session is Schwarz’s presentation on a topic he researched, and published on the PW blog on April 20, 2007. The published article shows the steps required to properly do the job, and mentions “…a list of 14 different techniques for sharpening this rectangle of steel that have been published since 1875.” In the video he talks about the references he found, from “12 dead guys and 2 living”, and which were the foundation of this work.
For Part 1:
In this first Part, Chris covers the historical background (nothing about sharpening scrapers appears in the literature until 1875), his work on wood failure (Types 1, 2, and 3 shavings, and why tearout occurs), and the first part of scraper preparation: Filing the edge.
The next two episodes will show the rest of the session with Chris, and the wonderful shavings he produces with a well-sharpened scraper.
In three areas I came close to disaster – the camera and tripod came close to falling to the floor… My apologies, as I also had trouble with tight tripod movement. But the entire session is on video.
