I learned how to make hooks from Geronimo Bayard in May of 2001 . He was quite a character. Nail-in hooks were the first project in his beginning blacksmithing class. They teach drawing-out and bending. Hooks are also handy to have around.
I'd like to thank my wife, Dorothy, for taking these photographs of the process I use to make hooks
The
piece of steel in the pictures is 5/16 inch square bar, eight inches
long. You can use a bigger or smaller piece to make a longer or
shorter hook.
-----------------
First, I measure about
two inches of steel beyond the edge of my anvil. This is conveniently
the width of my hammer.

-----------------
I
begin drawing out the bar from this point, trying to get an even
taper about four and a half inches long. It will be important for the
tip to be as small as possible without risk of burning it up. The
taper is rounded. (Forge S-O-R: first Square, then Octagonal, then
Round)
-----------------
The
piece curves a bit during forging, but is easily straightened. Always
position the piece with the bulge upward and flatten toward the
anvil. I like to use the "step" by the anvil's table for
small pieces like this.
-----------------
Don't
forget to brush off any scale that clings to the work.

-----------------
The
next step is to make the curlie-Q on the tip. This adds a lot of
character to the finished piece.
Take a good heat - bring the
tip up to yellow, but be watchful so as not to burn it. Hold the
hammer face at a forty-five degree angle to the work and "brush"
the end as it sticks over the anvil. The piece will curl downward.
-----------------
I
usually need to true up the curl at this point. Then I continue by
tightening the curl. It's important during this part to be flexible
with specific technique. I try to "figure out what the metal is
trying to say to me." A little practice goes a long way with
these tip curls.
-----------------
Again,
some truing-up will be in order. Close up the curl as tightly as
possible.
-----------------
Next
I chamfer the edges of where the hook's belly will be. This is a bit
of a departure from what Geronimo taught me - he had us round a
sufficient length of bar prior to making the tip curl. The belly on
his hooks was a little thinner and nicely round. (His way allows for
using a shorter piece of stock to begin with as well.) It is
important for the belly not to have squared edges, as this could
potentially damage something that hangs from the finished hook.
-----------------
Now
it's time for my favorite mistake. (OK, so it's my second favorite
mistake.) Take another heat on the piece, making sure that the
curlie-Q is pointed upward in the fire. (Having it pointed upward
reduces the risk of burning it - which is my favorite mistake.) Lay
the piece over the edge of the anvil with the tip-curl pointed
DOWNWARD. (Up in the fire, down on the anvil.) It should rest right
at the point where the chamfering stops. Give a good whack or two
just beyond the anvil's edge. You should get about a
forty-five degree angle at the anvil's edge, with what Geronimo
called "inertia" in the rest of the heated piece.
____
Quickly and carefully quench only the tip curl
before making the hook body.
-----------------
Now
you can bang on the curlie-Q without deforming it. I use the same
"brushing" technique to bend the hook that was used in
making the tip curl. I do alternate this with banging directly on the
metal to form it to the anvil's horn. True up on anvil face
afterward.
-----------------
Now
that the hook is done, we can concentrate on the nail-in spike. Note
that you could just as easily put a second hook on the other side!
That would make an "S" hook instead of a nail-in hook.
Optionally, one could weld the hook onto a fireplace too, ladle, or
other implement. It's also possible to punch & drift a hole for a
ring or chain or such. The possibilities are limited only by the
imagination.
However,
I promised a "nail-in" hook, so that's what we'll do
here...
To make the "nail," we have to heat up the
opposite end.
-----------------
I
measure about two inches and draw out square to a point. Brush off
scale as needed.
____
Next, bend the nail over at a 90 degree angle. Make sure that
it is square and true it up.
-----------------
The
final step is to twist the bar. To get the most use out of the final
heat, the bending wrench should be pre-set to loosely fit the bar.
The vice should also be set up and ready to tighten.
-----------------
Heat
the piece up and clamp the hook body in the vice. Twist smoothly with
the wrench, 360 degrees. When finishing the twist, make sure that the
nail and the hook are lined up.
-----------------
Brush
of the scale, let it cool, and call it "done."
-----------------
To
install the nail-in hook, just nail it in!
