KnoB & Handle. After removing any
excess solder from the box joints
and cleaning up the brass body,
you’re ready to make the wooden
parts of the plane — the front knob
and the rear handle. Both of these
are made from glued up blanks.
You can cut the blanks to rough
shape based on the patterns pro-
vided. Then use rasps, iles, and
sandpaper to inish shaping these
pieces.
Brass Pin. The handle and knob
will get glued into the body of the
plane with epoxy. Before doing this
however, I added the brass cross
pin for the lever cap (see Figure 1).
This pin is installed by turning
the plane on its side and drill-
ing a 1 / 4 "-dia. hole through both
sides. Then after inserting the
pin, the ends are peened over to
rivet the pin in place. Then ile
the ends lush with the sides of
the plane. (This is covered in

If you’ve already made the jack
plane featured on page 44 of Aus-
tralian woodsmith. 62, this block
plane will be a piece of cake. The
construction is very similar to the
jack plane, only simpler. (Take a
look at the exploded view draw-
ing below to see what I’m talking
about.)
Brass Body. Just like the jack plane,
the irst step in building the block
plane is to make the brass body
of the plane. I started by cutting
blanks for the sides and sole of the
plane from 1/8"(3.17mm)-thick
brass stock. Figure 2 shows the
dimensions for the blanks as
well as the layout for the box
joints. (You can also download
full-size patterns for the brass
parts of the plane, as well as the
knob and handle that are added
later.)NOTE-check the dimen-
sions on your download. The
printer that you use may distort
the template.
The box joints are cut on the
table saw, using a jig and a spe-
cial carbide-tipped blade that
is designed to cut non-ferrous
metals. Since the box joints on
this plane are the same size as
55
115
the box joints on the jack plane, you
can use the same jig to make them.
(Refer to page 52 in issue No. 62 for
more information on making and
using the box joint jig.)
Once you’ve cut the box
joints, go ahead and cut the
sides of the plane to shape on
the band saw. Then cut the
sole in two pieces to create the
mouth of the plane (see Figure
2). Now you’re ready to solder
the brass pieces together. (You
can ind detailed instructions
depth in the Working with Brass
article.)
When it comes to gluing the
knob and handle into the body of
the plane, no matter how neat you
try to be, you’ll probably wind up
with a little bit of epoxy squeeze-
out to clean up. You can scrape and
sand this off once it’s dry.
The blade will rest on the
handle, so you want to make
sure that the face of the handle is
lush with the bevelled edge of
the throat opening in the sole of
the plane. If it’s not, a small ile
and some sandpaper can ix the
problem.
The last step is to add the
blade and lever cap.

making the cap

The lever cap is nothing more than
a hardwood wedge with a knob at
one end. The cap slips underneath
the cross pin in the body plane. By
tightening the knob, the edge of
the cap is forced down against
the blade, holding it in place.
The trick to making the
lever cap is to start with an
extra-long, squared-up blank
and drill all the holes irst.
Then you can taper the blank
to create the “wedge” shape
of the lever cap.
Start by drilling a counter-
bored hole for the T-nut (see
drawing at left). To create the
rounded groove in the front
of the lever cap for the brass
cross pin, drill a hole through
the edge of the blank.
Using a band saw, stand
the blank on edge and
cut the cap to its wedge
shape. Now just cut the
curved proile at the top
of the blank and sand it
smooth. Finally, add the
T-nut and knob.
