This is Part 3 of 3 of the session on Scrapers: History, Preparation and Use, with Christopher Schwarz. Part3 concludes the series on scrapers.
To get some continuity from Part 2 into Part 3, I included the last 3 minutes from Part 2 as the introduction to this episode. This way you can get back to speed quickly.
In Part 3 Christopher Schwarz actually draws the burr on the scraper. This Part starts with some discussion by The Schwarz on drawing the burr, and continues with the rest of his findings on the study he conducted:
Approximately the last half portion of Part 3 consists of a Q&A session. Several very good questions originated from attendees to this session, with (what else?) equally good answers from The Schwarz.
I hope you enjoyed this three-part series on scrapers, and hope you will return for more videos from the following sessions I attended:
Not on video, but rather from my own notes, I will have a post on Modern Tools, Tolerances & Myths, with Robin Lee, Thomas Lie-Nielsen, Konrad Sauer, and John Economaki.
I would love to receive your Comments, and any questions or suggestions regarding the Woodworking in America series of videos, and any other content.

Note: I split this session into three parts, for easier downloading of the high-resolution file, and viewing in shorter segments. I apologize for the clumsy tripod movements – for example, at around 50 seconds into the video, the camera came close to hitting the floor. But everything in the session is on video.
By the end of Part 1, Christopher Schwarz had covered the history of scrapers, using information from “…12 dead guys and 2 living…”, the literature back to the mid-1800s; he was unable to locate earlier references in the literature. He also covered interesting facts about how wood fails, documented with superb photographs of the types of shavings formed. As Part 1 ended, he was filing one edge of the card scraper on the bench.
It is worth repeating here that this work first was published on the PW blog on April 20, 2007; you might want to keep the printed article for future reference. In my opinion, though, it is worth the time to watch Christopher Schwarz go through the entire procedure, in which he fully documents every step, and many misconceptions, about sharpening card scrapers.
Now, Part 2:
In this episode Chris does the prep required to get the edge ready to turn the burr, and covers the following:
It was only earlier this year I finally found myself able to properly sharpen a scraper with any kind of repeatability. But, if you are still struggling to get nice, thin shavings, this session is for you!
