5 Notice the burn
marks left by the
saw blade. A blade
on which the teeth
have set won't burn;
however, the
hollow-ground
planer blade is made
without set in order
to produce a
smoother cut and, as
a result, often leaves
a burned surface.
BURN RE MOVAL
I have read that a hollow-ground planer blade can be per-
suaded to cut without leaving behind the unsightly, black-
ened surfaces visible in the above photo. I have read that
if the blade is razor sharp, free of pitch, and set perfectly
parallel to the rip fence, it is possible to cut without burning.
But I haven't been able to manage it.
I clean the blade frequently, and it is kept sharp, and
of course I make an effort to properly set the rip fence,
but 1 always end up with burned surfaces on one or both
sides of the cut.
This could be a result of the fact that machine tool
maintenance is not a priority in my shop. Although I have
the standard array of power tools, I use them no more than
necessary and never take pleasure in their operation. They
produce too much noise and too much dirt, making the
shop a thoroughly unpleasant place to be.
I have, instead, focused on methods for removing these
bum makes from cut surfaces.
Those in the above photo are relatively easy to eliminate.
Placing the tip of an extremely sharp 1" butt chisel across
the thickness of the blackened wood, I drag the chisel
backward (in the direction opposite the bevel) in a scraping
motion. Two or three passes removes most of the scorching,
in addition to leveling any irregularities left behind by the
sawing process. A little work with sandpaper wrapped
around a bit of flat scrap then completes the clean-up
process.
The scorched areas resulting from the formation of the
raised panels on the four sides of this box are a little more
difficult. Because the raised panel is immediately adjacent
to these flats, they can't be straddled with a chisel. Making
the process even more difficult is the fact that the vertical
flats on each end of the raised panels run across the grain.
The solution? The only one I know requires patience
and a lot of work with a fine-toothed wood file and sandpa-
per.
I suspect that it would take less time to tune my table
saw so that a hollow-ground planer blade wouldn't burn
cut surfaces than it does to remove the burn marks after-
wards. I suspect that I'm not using my shop time as wisely
as I might. But there is a trade-off here. To achieve the
overall time savings, I would have resigned myself to several
hours of frustrating, knuckle-busting power-tool mainte-
nance, and the truth is that I would rather spend my time
scraping and sanding .
