Your scrapers can finish surfaces that are
impossible to plane. However, if you work too long in one area, it is
hard to control the flatness of the entire surface. A scraping plane is
useful to use in combination with hand scrapers. Work difficult areas
with the hand scrapers as needed; keep the surface flat with the
scraping plane.
The thinner blade (.020") is quite flexible and is great for scraping
shorter, complex surfaces. The thicker blade (.032") will take
a heavier cut, and is best for larger surfaces.
Burnishing:
Before you use the scraper, it is helpful, but not absolutely
necessary, to turn a burr on the edges. To create a burr, hold the
scraper upright in a vise. Use a burnisher and begin by holding the
burnisher at 90° to the blade, decreasing the angle
with successive passes. Work the edge until you can feel a
distinct ‘hook’ all the way across. Be very careful
not to cut yourself on the upright scraper.
Use of a burr will give more aggressive cutting action.
When re-sharpening, first hone the old burr off, then square the edge
with a stone or file, and repeat the burnishing process. You can
usually re-burnish a few times before it becomes necessary to square
the edge.
Materials:
The Lie-Nielsen Hand Scrapers are made from premium, high carbon
Swedish Tool Steel hardened and tempered to Rockwell 49-51. They will
take a burr well and last a long time. The long sides have been ground
square. If you wish to use the short sides, file square before
burnishing.
Maintenance: The
scrapers are made of Steel and will rust. Keep them lightly oiled and
wrapped in cloth or treated paper when storing the scrapers between
uses.
