A steel scraper is a pice of steel 0.85mm
thick by 2 1/2 " x 6". My favoured brand is from a Sweedish
company formerly called Sandvic, now known as Bahco (more
info). The illustrations below help clarify the videos. . |

The illustration above shows the 3 views
of a steel scraper on the right and a close up of the side view with
a jointing file on top. The idea is to file the top edge of the scraper
at right angles to the face, leaving a sharp square edge. |

This illustration shows 3 stages in working
the top edge with the jointing file. The irregularity on the scraper
is exaggerated to illustrate an idea. The top view is what you are
looking at as you file and you can see the areas the file cuts are
brighter than the hollow areas and as filing continues
the bright areas connect. At the moment all the bright areas connect
the edge of the scraper is dead flat. So when you hear me talk about
"seeing" and "feeling" in the video clip this
is the seeing part. The feeling part is obvious, as the work approach's
flatness the file is taking more and more on each cut, requiring more
effort.

The
reasoning behind stroping the scraper only once |
 |
|
|
| The exagerated illustrations on
the left show the sharp right angled edge of the scraper close
up. Far left (1) is a freshly prepared scraper with one edge
stropped only once, the turnover is slight, only that sharp
right angle, the business end, has been turned over. Pic #2
has been stropped repeatedly, a lot of turn over , and the question
is why? When the business end, that sharp right angle, is no
better from the extra strokes and to return it to optimum condition
(flaten it back and stroke it with the steel strop again) will
require more work than the edge stroked only once. It's really
a case of the most efficient method and with only one stroke
with the strop the tool can be maintained in optimum condition
with the least work. |

Cleaning
up large surfaces is just the begining of using a steel scraper
and, thankfully, is also the most demanding way to use the scraper.
The way you hold the tool is the secrect, when you have the
handling technique down and you can clean a flat surface really
well, effortlesly pulling a good shaving, the rest is easy.
Here's more on how to hold the scraper
and a review of the ways to tackle flat surfaces, moving on
to clips of cleaning up variuos chair components starting with
flat shapes then cuved and cylindrical shapes, and I use the
scraper towards and away from myself.!!! The difference is that
the effort required cleaning up a flat
surface is huge compared to that for working curved/cylindrical
forms (like the chair top rail), the effort required is tiny
by comparison so the scraper works well in either direction.
Consider this clip as an introduction to the incredible versatility
of the steel cabinet scraper. |
