Mark Aspery, Instructor of Blacksmithing
Sierra Forge and Fire.
As a professional smith and blacksmith
instructor, I am often reminded how little I
actually know about the craft of blacksmithing.
To that end I usually try and attend a week-long
blacksmithing class a year.
This year I attended a Darryl Nelson class at the
John C. Campbell School in North Carolina.
My thanks go to the Francis Whitakker
Blacksmith Education fund for approving a
grant that made this possible.
Step 1 A
As a class we made a number of different
animal heads during the week. The class started
with a bearʼs head. The stock was 1 1/2” square
hot rolled A36. Length can vary, but you will
need enough to hold in the vice with about 4-
inches protruding above the jaws. The other end
needs to extend past the box/screw mechanism
so that the work-piece does not turn cartwheels
in the vice as you work. A handle welded on
will address this situation as well as making the
bar a little lighter to work with.
Step 1 B
Step 1; The basic shape
Forge a taper to the end on three sides only. The
end should measure about 9/16” wide by 7/8”
tall and taper back to the parent bar-stock over
1 1/2 inches.
Step 1 A
To create the brow, turn the bar so that the
straight side is uppermost and with about 2/3 of
the taper resting on the anvil deliver a half faced
blow. You should be working over a rounded
portion on the nearside edge of the anvil when
you do this. Leave a slight taper from the
shoulder to the end of the bar.
Step 1 B
To deine the jaw and front of the cheeks, either
use a top and bottom fuller as shown or a spring
swage at least 1/2-inch diameter. The rear of
the fullers should not extend past the brow line.
Fuller in to leave about 5/8-inch and a slight
taper to the front of the jaw.
Step 1 C
Forge in the remaining stock using the edge of
the anvil and your hand hammer. The snout

will have a rounded top and a lat bottom to start
with. Place the bottom of the jaw on the anvil and
knock the corners of the top of the snout with a
view to making it round.
Step 1 D
If you cannot see a bearʼs head in the rough at this
time, itʼs time to get the book out and see what
exactly it is that you are making!
Step 2; Fuller work
To create the eye socket, deine the brow and the
top of the cheek bone you will need a hand held
1/4 to 5/16-inch fuller about 7/8th to 1-inch wide.
Fig 1.
With the center-line of the fuller in line with
the top of the snout and the side of the fuller
extending slightly over the snout forge in the
eye socket. Remember that carnivores have their
eyes facing forwards, so do most of your work
from the front. Herbivores have their eyes on the
side of the head. My wife seems to have eyes
everywhere, especially when it comes to sneaking
in a new tool!
Step 2 A
Extend the fullering around the side of the head
and blend it into the parent bar-stock.
Step 2 B
Bears sometimes have a ruff around the neck and
a beard under the jaw. This next use of the fuller
deines both of these features. Starting with the
edge of the fuller where the eye socket inished
fuller in a walk to tool down the side of the bar.
Angle the fullered groove towards the jaw to
deine the rear of the cheeks. First create a groove
by fullering at 90-degrees to the bar and then
come back and push the stock back to create the
ruff. I am breaking this step into two parts but in
reality the making of the ruff and the beard are the
same step and techniques.

Once you reach the bottom of the bar when
creating the ruff, turn towards the jaw and with
the fuller on the corner of the bar start to push
the corner into the bar to create the beard. The
beard does not run to the very end of the jaw but
stops someway before.
Steps 2 D and E show work in progress.
Step 3; The Ears
Using the same tool as above, place the business
end above the eye socket and hold the tool at
an angle. You will push material back from the
face to create an ear and at the same time create
the eyebrow. As you push the material back
drive the material slightly towards the centre
of the bar. If you omit this step the tool will be
delected upwards and you will have very small
ears. Of course, too much angle and you end up
with bat ears. Step 3 A
Step 2 E
Step 3 A
Taking a sharper than normal centre punch,
place the point at the bottom, centre of the ear.
Drop the angle of the punch so that the taper
on the end rests lat upon the brow and make a
depression of about 1/8-inch or so. If you feel
like youʼre driving towards the brain you are
holding the centre punch at too steep an angle!
Step 3 B
Step 2 F
The forehead is formed using the same tool. A
bear has a pronounced forehead. With the inside
of the tool on the centre-line form two grooves
each running back and angled away from the
centre-line. Do most of the work by the snout
and feather out the fullering as you get to the top
of the head. Blend in the sharp edges with the
same tool. Step 2 F
Step 3 B
783633092.005.png 783633092.006.png
Using a hollow ended fuller, (Fig 2) place one
corner in the depression you just made. Rock
the tool out so that it touches the body of the ear
as well. Start from one side and spread the ear
out giving it texture as you go.
You may need some clean-up work from the
back of the ear with either the fuller or the
hollow ended fuller.
Step 3 B and 4 A show the results
Using a hand held butcher or your hand chisel;
cut a groove around the lower jaw about 1/16-
inch down.
A hand held side set will push the upper section
in to create the lower lips and give you the mass
to cut the lower teeth.
Step 4 B and C show the progression with the
arrow in Step 4 C showing the result of using
the side set on one side only.
Mark the center of the tongue with an offset
chisel
Taking a small curved chisel, again ground on
the outside of the tool edge, cut the tongue. Start
about 1/16 th -inch back from the front of the
teeth. Step 4 C
Step 4 B
Step 4 A
Figure 2
Step 4; The Jaw and tongue
Drive a curved hot chisel held about 2/3ʼs down
from the tip of the nose cut the mouth. Angle the
cut down towards to bottom of the head as you
go. This will leave a nice taper to the snout from
the tip of the nose back to the cheeks with the
curve leaving a hollow in the upper jaw.
I have my chisel ground on the outside edge to
help with this.
Step 4 A.
Step 4 C
783633092.007.png 783633092.008.png 783633092.009.png
Start by cutting down; but quickly change the
angle of the cut to the back of the jaw. If you dig
too deep you can seriously shorten or upset the
lower jaw and give your bear an overbite.
Work the chisel back to the rear of the mouth.
Donʼt allow the tongue to touch the top of the
mouth as getting it down can be both frustrating
and damaging.
Step 5; The Teeth
Using the same curved chisel, start at the center
of the front teeth and cut irst to one side and
then the other. This creates the mass for the
canines. Donʼt aim too deep as you cut. Use a
smaller hollow ended fuller and work the mass
into sharp canines.
The offset chisel will mark the other teeth both
on the side and on top as shown.
Step 5 A and B
tep 5 B
Step 6; The Nose
Using the same curved chisel as above mark a
line for the nose. Remember that a bear has poor
vision but a really keen sense of smell. Donʼt
skimp on the nose!
On the front of the snout create a good line
leaving the nose forward of the rest of the stock.
On the top of the snout use light blows as you
are identifying only the edge of the hairline.
Use a smaller curved chisel and aiming slightly
towards the centre of the snout put in the
nostrils. Allow them to lare a little. Leave a
little gap between the two chisel marks.
Use the side set to push away the stock to the
side of the nose to make it stand out a bit farther.
The result is shown in Step 6 A
