I keep looking on the web at the intricate, beautiful, wooden models made by the "compagnons" in France.
They are made as part of the apprenticeship of young craftsmen who move around the country staying at different
places for 6 months at a time to learn their trade. Fascinating that such a training system should still exist in the
modern day and age.
I found an article in Arlas Obscura that talks about the system.
Paul Krenitsky introduced the workshop on card scrapers.
As well as demonstrating how to use a scraper Paul showed his Veritas scraper kit which includes both a sharpening and a burnishing jig. Plus he showed the
Veritas scraper holder, a metal and plastic fixture that grips the scraper and can put a bend in it. This reduces the stress on hands and thumbs.
DVD that is available on Hand Scrapers
A card scraper is a sheet of hard steel which is smooth and square and then has a raised burr on its edge.
Several members demonstrated their preferred techniques for raising a clean burr.
Chris Pribe showed a very precise method based on ideas from Chris Schwartz. He uses waterstones to create a smooth
square edge and to smooth the faces. He uses a scrap of plywood to hold the sheet square while smoothing the edge. He uses a ruler to space the sides off the stone so only
the part of the face near the edge needs to be smoothed. He then runs the burnisher a few times on the flat side to create a bur. He then clamps the scraper in a vise
and gives the edge a few strokes with the burnisher held at a small angle.
Burt Rosenzweig showed a simple method using medium and fine whetstones to smooth the edge and faces. He drills a hole at a 2-degree angle in a wood block to hold his burnishing pin and just lays his scraper flat on the block against the pin to roll his burr.
Per Madsen uses a special purpose chuck he purchased from Woodsmith that holds a metal file as well as a burnishing pin.
Jon Blackmore uses a Lapsharp to do the initial squaring and smoothing. He cuts a thin kerf with a bandsaw in a block of maple and clamps the scraper in it while doing the
Yeung Chan showed a wooden scraper plane he made which will not only smooth difficult grain without tear out, but will also improve the flatness of the surface. The blade
is dragged at a 5 degree angle. He explained that hand scrapers must be used with caution as they can create grooves in a flat surface if over used.
Stan Booker mentioned that Carl Johnson had given a talk on card scrapers at BAWA in 1990.
After a 30-minute break for scraping practice we had show and tell.
Dennis Yamamoto described a project to replace a house door. The panels were Honduran Mahogany with
Redwood stiles. He used the leftover wood to make a cabinet with coopered doors. The coopering was hard to do because of the difficult wood grain. The dovetailed drawers
were all concave. He was also asked to do a small table for Deer Hollow Farm which he made out of Sapele with tapered legs. He then described a large dining table, 7 feet
long by 30 inches wide, with curved stretchers and a curved top. Joinery was mortise and tenon.
Bruce Powell brought in the completed footboard from the Elm queen size bed he has been fabricating. 3 inch long dowels reinforce the mortise
and tenon joints between the legs and the panel.
Yeung showed an example of his Chinese table leg base joint which consists of 3 pieces splined together at 120-degree angles.
