#40. WIA: Bevel-up vs. Bevel-down Planes

Download High Resolution
Running time: 1 hour, 14 min., 42 sec.

Christopher Schwarz moderated this session on the second day of Woodworking in America in Berea, KY. Robin Lee and Thomas Lie-Nielsen participated. Highlights of items covered during this session:

Summary (from notes I took during the session – but everything is on the video):

  1. Characteristics of both types of hand planes.
  2. Questions with Robin Lee and Thomas Lie-Nielsen.
  3. Questions from the audience.

Now for the good stuff:

Using a Veritas bevel-up plane as an example, Schwarz explained:

  1. There is no removable frog.
  2. These have been called “low angle” tools, which can be confusing because they can be made into high-angle tools.
  3. What changes when using a bevel-up plane? We gain, due to some of the following advantages, and lose some due to a few disadvantages:
  • The sharpening angle of attack influences the angle of the tool: Low angle, for end grain, for example; and high angle for “tricky” grain.
  • The adjustment mechanisms are vastly different; they result in easier, and more accurate, blade adjustment with the bevel-up tools. Blade projection is easier; but lateral adjustment can be more tricky on the bevel-up planes.
  • There is no separate chip breaker. Robin Lee discusses wood failure.
  • Some discussion followed on changing the angle of attack by changing the back bevel on the iron; Schwarz does not like this approach, as it doubles sharpening time.
  • A major advantage of bevel-down smoothers and jointers: Making adjustments “on-the-fly”, which gives great feedback to the user.
  • A disadvantage of the bevel-up tools: Cannot “point” with the index finger, or make adjustments.

Starting about 45 minutes into the session, the panel took questions from the audience. This was a great session with two major players on the tool manufacturing side, an amateur woodworker who doubles as a magazine editor, and an audience hungry for information.

#39. WIA: Advanced Dovetailing with Frank Klausz

Download High Resolution
Run time: 1 hour, 51 min., 47 sec.

Frank Klausz returns in this episode on Advanced Dovetailing, to share how he makes half-blind and mitered dovetails. He shares tips that are crucial to get excellent joint fit with a minimum set of tools. I filmed this during his wonderful session, at the Woodworking in America hand tool conference in Berea, KY.

The session opened with Klausz talking about his background, and his search in America for “…others who made dovetails like his grandpa made them, back in Hungary…”. He later told the audience he has made “… a total of 12 of these, and now is getting ready to make his 13th mitered dovetail joint…”

Pins-first is the order of the day when making both, the half-blind, and the mitered varieties of dovetails. Klausz also uses a sharpened pencil to mark the tails from the pins; and, from the Pins vs. Tails dovetailing videos I filmed during his first session, white glue is what he uses to assemble the dovetails. He considers white glue a great stress-remover when the time comes to glue up dovetail projects – the longer open time of the white glue is good for these, he says. Of course, he is right.

#38. WIA: Part 3 of 3 – Forgotten Workbenches and Workholding

Download High Resolution
Total running time: 48 mins, 54 seconds

This episode is all about workholding:

  1. Face vises – Racking is the main reason The Schwarz does not like them.
  2. Leg vise: Elegant, cheap, GREAT!
  3. Shoulder vise: Best choice for dovetailing drawers – it is fast. It is great, but too complex.
  4. Crochet: Used with holdfasts, it is great, and cool.
  5. Sliding dog vise: Otherwise called the Wagon Vise. Recently installed one on of his benches.
  6. End (tail) vise on European-style benches: Fragile, and they sag!
  7. Dogs: Round or square? Likes square, bur coming around to round. It is hard to make square holes. The round dogs are best because there is a large after-market that caters to these.
  8. Battens: Offer an effective way to work: Low profile, and cool.
  9. Planing stops: Made from scraps; make them as thin and wide as possible; install on the face vise.
  10. Planing boards: Great if the workbench is not flat; Chris has made available a construction drawing on his blog.
  11. Deadman: Installed on his Roubo; has nothing but praise for it.
  12. Other benches: Concrete block bench; wheelwright’s bench, with leg vise and cabinets; the Modern Roubo”; the English hybrid, with angled leg vise but straight legs; Moxon’s bench; the “sink” bench (laughter!), which is a Shaker bench corrupted.

The Schwarz answered many questions, all terrific and relevant, until he ran out of time. The discussion could easily have run much longer, but everyone had to run to lunch, to the Marketplace, and to other terrific sessions.

I took a good look at the construction of the sliding deadman…
