Run time: 34 minutes, 30 seconds

Christopher Schwarz, Editor of 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 downloading and viewing. This is the high-resolution video (as high as I can get with an old video camera).

Background:

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.

Apologies:

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.

# 31. WIA – Dovetailing: Pins vs. Tails, Part 3

Run time: 17 minutes, 04 seconds

In this episode Frank Klausz discusses the importance of undercutting below the base line, and his preference for cutting both pins and tails flush with the boards. Roy Underhill introduces the concept of “bishopping”, which involves leaving the pins proud and using a ball peen hammer to “spread out” the protruding wood to make the fit appear better than it truly is.

Later, both present several variations on the dovetails:

  1. Half-lapped (or half-blind) dovetails: Look carefully inside this joint, as “there is room to undercut in every direction”.
  2. “Secret” mitered dovetail: Most of the joint is concealed, so it is impossible to determine how “clean” the joint may be. Frank Klaus will cover more on this joint, when he actually cuts one in the Advanced Dovetailing session. I will also have this session on film.
  3. In one segment Roy Underhill calls himself “The Rhinestone Wood Guy” – to the delight of the audience.
  4. The Puzzle Dovetail, done on the diagonal.
  5. The Rising Dovetail, used to hold mallet heads and highlighted on the workbench in use for this session.
  6. The Swallow Tail dovetail – I am not sure if this one is accurate, but it is on the video. Klausz and Underhill agreed that this one is truly a scarf joint. And I believe it is a very interesting joint. Layout involves careful work with gauges, etc.

A short discussion ensued on chisels suitable for dovetailing work. Most important: Sharp cutting edges, and beveled edges, to allow the chisel to get in tight quarters! When asked about the best angle to sharpen the chisels, Klausz answers, true to form: “The angle is SHARP!”

# 30. WIA – Dovetailing: Pins vs. Tails, Part 2

Run time: 21 minutes, 05 seconds

In the last episode, Frank Klausz and Roy Underhill reviewed the basics, and why dovetails should be cut a certain way.

In this episode Frank Klausz actually cuts the pins and the tails, explaining in detail how the layout should be done for best results. Hilarious at times, but dead serious when it comes to the subject of dovetails, it is easy to see it is passion in its purest form that drives Klausz to be the master he is.

When asked if plywood would be OK for drawer bottoms, his response was “… I would NOT have plywood in my house – here, take 30 dollars and buy some decent hardwoods for those drawer bottoms…”

The through dovetails he cut during this session were perfect, without the need to do any “bishoping” (using a small hammer to fill in the gaps in the tails). This is explained in the video in detail. The joint Klausz made – consider he did this with a camera over and under his shoulder, and other fun interruptions:
