Manual for setting up the Veritas Skew Rabbet Plane
The
Veritas Skew Rabbet Plane is one of the most important tools in my
workshop. It is used to create fine rebates in drawer bottoms
...
...
and planing large rebates for the rear panels in cases
...
There
has been some discussion about the difficulty in setting up this
plane, in particular, positioning the blade and nicker. This is
complicated by the skew blade, which is more tricky to sharpen to the
ideal profile than a square blade. There is a significant advantage
for a skew blade, which makes this worthwhile, this being that the
plane will plane cleanly across the grain.
You
will note that the front knob has been removed on my personal plane.
I will explain this shortly, and advise that others do the
same.
Two
items here: the first is the sub-fence. This is 240mm x 40mm. It
provides greater registration, while the wood offers less resistance.
Secondly, the brass knob for the depth stop has been given a slot for
a screw driver. This makes it easier to lock down more securely.
I
have two fences, a straight one for rebate work, and an angled one
for raised
panels ...
There
are two areas which are vulnerable to movement, which will be
disastrous: the depth stop, above, and the fence, which is locked
down by circular brass rings. It pays to tighten these further. I use
a pair of plastic-mouthed vise grips (which will not damage the
brass) ...
Inside
the body is a screw ...
This
controls the nicker. Loosen the screw and the nicker will slide
in-or-out of the body. The nicker is used when planing across the
grain. It sits ahead of the blade and creates a path for the blade to
prevent tearout. It is not needed when planing with the grain.
It
is the harmony of blade and nicker that determines how well the
rebate plane with work:
1. The blade must project a smidgeon
(technical term for 0.5mm) from the side of the body. This is
necessary to cut into the inside corner of the rebate. If it did not,
the plane will be forced progressively away from the wall, creating a
slope instead of a square face.
2. The nicker needs to be at,
or slightly further away from the body than the blade. If the nicker
is set too close to the body, it will not pre-cut for the blade, and
the result will be tearout along the shoulder of the rebate.
3.
The blade projection needs to be set parallel with the sole. If it is
canted one way or the other, it will prevent the floor of the rebate
being square to the shoulder.
Set the nicker before you
set the blade. This is the nicker. It is screwed on at an offset so
that it may either project below the sole, or above the
sole.
Remove
the screw ...
...
and sharpen the nicker. Just a few rubs on a fine diamond stone will
do this. Mine is a 20 year old 1200 grit ...
Loosen
the screw that holds the nicker barrel, and it will come out ...
Setting the nicker
…
with blue tape ... what else
did you expect from me! ....
Three
layers of blue tape will total about 0.5mm. Replace the nicker and
barrel. Orientate the screw to the lower end for the nicker to
project for a cut ...
Now
place a rare earth magnet on top of the tape. This will lift up the
nicker to this height ...
Once
the nicker is set, install the blade. Set is just a fraction inside
the nicker. Once positioned and locked down by the lever cap move the
set screws into position (against the blade). This will enable for
set up to be done without any fuss.
It is not that easy to see
here, but both the blade and nicker project from the body ...
Now
set the depth stop, and lock it down. The ruler is measuring from
below the depth stop to the tip of the blade (not the edge of the
sole) ...
Here
is a demonstration board, where we will create a rebate across the
grain. This is soft wood, which will penalise any set up errors with
tearout along the shoulder line.
To
set the fence, what I do is mark the width of the rebate with a
cutting gauge, and then place the nicker in the cut line, and push
the fence up against the side of the board.
The
hand position is thumb where the knob would have been, pushing down,
and palm against the fence, pushing against the side of the board
...
Start
the first cut at the far end. This creates a down hill slope, which
planes more easily (like planing with the grain). Also, deepening the
shoulder progressively will minimise tearout.
If you notice a
little tearout along the shoulder, loosen the blade screw
fractionally, and use a plane hammer to tap the blade in a little. I
could see this happening here very faintly, made the correction, and
then all was well.
Now move back and plane again ...
This
is the result we are after ...
Checking
for square ...
Setting
up the blade
Freshly
sharpened blade. The bevel has been hollow ground, and then honed on
the hollow. This blade will not need to be ground again for a long
time.
Try
and set the blade for parallel and side projection at the same time.
If it is not possible to achieve parallel, then the bevel angle needs
to be corrected. The problem is that, without the blade being
parallel with the sole - not with the mouth, per se - one side will
cut higher than the other. Do not worry if the blade is not even
against the front of the mouth. It will still cut appropriately.
Take
your time to get this right. Bevel angle of 30 degrees ...
Place
the blade in the plane. Note the set screws against the inside of the
blade ...
Once
the blade is positioned as close as possible - it is not final at
this stage - then tighten up the set screws until they touch the
blade ...
Once
the blade has been fully positioned, it is unlikely that it will need
to be set up again.
When making adjustments, such as
re-positioning the blade projection, press the blade against the set
screws, then loosen the lever cap, and use the adjuster
...
