Use
and Sharpening Instructions for Hand Scrapers
Owning
Hand Scrapers will help you cut your sanding and finishing time
in half. And the end result will be considerably better than if
you had used sandpaper alone!
Hand
Scrapers will remove material faster, and at the same time, eliminate
uneven spots that sandpaper and steel wool only help to magnify.
But they can do more than remove a tissue-thin shaving at a time
- they can also be used to remove glue and lacquer more efficiently
than with any other method. So keep them out in the open and well
within reach!
But
before you begin, a few words on proper sharpening and use to help
you along...
Sharpening
Your Hand Scrapers in Six Simple Steps
-
Clamp
scraper in vise
-
File
edges perfectly square with Single-Cut Mill File
-
Hone
edges with Medium India stone
-
Hone
with Hard Arkansas stone
-
Remove
honing burr
-
Burnish
edges with a burnishing tool or the shaft of a screwdriver
|
|
a)
Clamp scraper in vise, hold file even with the blade edge, perpendicular
to scraper face. Draw in long even strokes. |
b)
Remove file marks with a Medium India stone; complete honing
with a Hard Arkansas stone. Avoid rocking the stones at all
times. |
|
|
c)
Move sharpening stone along both faces of the scraper until
burr is completely removed. |
d)
Hold the burnisher or screwdriver shaft at about an 85-degree
angle and draww it lightly, both down and along the edge of
the scraper at the same time, until a slightly even burr forms. |
Special
Tips:
-
When
scraper edges dull, it is not necessary to follow the complete
sharpening procedure. Simply burnish old burr up flat, then
form a new one at a slightly lesser angle (e.g. 80-degrees).
After putting new burr on four or five times, follow complete
sharpening procedure.
-
The
most common sharpening mistake is burnishing too hard! This
gives the burr a big hook which will dig too far into the wood
(except when scraping rough stock).
-
For
rough work (removing glue or lacquer, rough scraping) - simply
file edges; sharpening stones is not necessary.
|
|
a)
Curl fingers around scraper ends, bowing it slightly with thumb
pressure. |
b)
Angle the scraper away from you at about 70-degrees from the
work surface and push... |
|
|
c)
...or toward you and pull. |
d)
Hold the scraper diagonally, but move parallel to the grain
of the wood. |
|
|
e)
Hand Scrapers should not make dust. |
f)
...they should make tissue-thin shavings! |
Getting
The Most Out of Your Hand Scrapers
-
Bow
scraper slightly, using thumb pressure
-
Hold
at about 70-degrees - not perpendicular to work surface
-
Hold
askew to grain, but move with the grain
Additional
Uses For Hand Scrapers
Although
Hand Scrapers are primarily used to remove machine marks, they are
also great for:
-
Removing
glue
-
Removing
old finishes
Special
Tips:
-
Depending
on the angle of the burnish, scraper must either be held flatter
or more upright to produce shavings instead of dust.
-
A
dull or unevenly burnished edge will also make dust instead
of shavings.
-
After
scraping machine marks, wood blemishes, etc., scrape to the
sides, front and back of this area to avoid creating "dips."
Note: Hand Scrapers (properly sharpened) will leave a smoother
surface than 220-grit sandpaper. Lack of this area to avoid
