Why a Coat Hook Makes an Ideal First Forging Project

A coat hook is one of the best teachers in the forge. It uses almost no steel, takes under an hour once you know the steps, and quietly walks you through drawing out, twisting, scrolling and finishing — the four techniques that underpin nearly everything else you will make later. It is also genuinely useful, which matters more than it sounds. A hook you hammered yourself and screwed to the wall by the back door will teach you more about why a twist sits evenly or a scroll opens too wide than any practice bar ever will.

This project is designed for someone with basic hammer control. A gas forge is easiest, though a solid fuel forge works perfectly well. Mild steel is forgiving, cheap and predictable, so leave tool steel on the rack for now.

Tools and Steel to Have Ready

• Steel: one length of 10mm round mild steel, roughly 250mm long. This gives you a backplate, a twisted shank and a scroll with room to spare.
• Tongs: a pair that grips 10mm round securely — the hook will try to spin if the jaws are loose.
• Hammer: a 1–1.5kg cross-peen or ball-peen. Heavy enough to move metal, light enough to control.
• Twisting wrench: a large adjustable spanner or a dedicated twisting bar. A vice with soft jaws is a good anchor. Two pairs of hands make it easier.
• Wire brush with stiff steel bristles, ideally one for brass brushing.
• Pillar drill with a 4–5mm bit and a countersink, or a good cordless drill and patience.
• Finishing: beeswax, boiled linseed oil and a lint-free cloth.

Never forge galvanised, plated or painted steel. The coatings give off genuinely harmful fumes and will ruin your lungs and your coal alike.

Forging the Backplate and Shank

Start at one end. Heat the last 45mm to a bright orange and forge it into a flat tab about 30mm wide and 6mm thick, working from the centre outwards with light, edge-to-edge blows. Keep the tab symmetrical — a lopsided plate looks careless on the wall. If you fancy a fishtail, spread the very end a little wider, then true the edges up with a file once it cools.

Next, draw down the middle of the bar if you want a tapering shank. Bring about 100mm to a bright orange and gently reduce the diameter to roughly 8mm, rotating the bar a quarter turn between blows so you keep it round rather than diamond-shaped. Aim for a smooth, gradual taper. If the metal starts to look dull red, stop and return it to the fire — working cold steel only causes bruised edges and cracked shoulders.

Now mark your twist zones. Chalk or a light centre-punch mark works well. A pleasant, rustic layout is a 60mm plain section, a 60mm twisted section, then a short plain gap before the scroll.

Twisting the Shank Evenly

Twisting is where most beginners rush, and where most hooks end up looking uneven. The secret is heat and steadiness, not force. Bring the marked section to a full, even bright orange — not a sullen red, not a sparkling yellow. Clamp one end in the vice, fit the twisting wrench to the other, and turn smoothly, keeping the bar dead level.

As a guide, one full rotation per 25mm of length gives an open, hand-forged twist. One and a half rotations per 25mm gives a tighter, more formal pattern. Count your turns and stop at the same number each time; that consistency is what separates a nice hook from a scrappy one. Let it cool in air rather than quenching — a quench can leave the twist brittle and slightly rippled.

If you want two twists separated by a plain band, twist the first section, allow it to cool, then repeat. Trying to do both in one heat rarely ends tidily.

Shaping the Scroll

Draw the tip of the remaining end down to a soft taper, roughly 5mm at the point. This makes the curl graceful rather than blunt. Now heat the last 40mm and bend the first 20mm to about 90 degrees over the horn of the anvil. Once that initial bend is set, work progressively: bring the curl forward a little at a time over the horn or a scrolling fork, closing it into a spiral with a small gap between the coils. A good scroll resembles a fern frond — inviting, not cramped.

Keep the scroll in the same plane as the backplate. Check it by laying the whole piece on a flat surface; any wobble means a correction while the metal is still warm. Small adjustments with a pair of bending forks are far easier than they look.

Finishing, Fitting and Aftercare

Drill two 4mm holes in the backplate, about 20mm apart, and countersink them so the screw heads sit flush. Drill while the plate is flat and supported — forcing a drill through a curved plate is how bits snap.

For a traditional black finish, bring the whole hook to a dull red and brush it hard with a steel wire brush. This lifts the scale and leaves a soft, smoky grey. Then warm it to around 200°C — hot enough that spit sizzles — and rub in beeswax or boiled linseed oil with a cloth. The wax melts into the surface and cures to a warm, satin sheen. For interior use, a coat of clear lacquer over the wax keeps the finish from marking wallpaper.

Fit with two 4mm screws into wall plugs or directly into timber, and check that the curl clears the wall by at least 40mm so a coat can actually hang. Every year or so, warm the metal lightly and reapply a little wax. That small ritual keeps a simple hook looking well-kept for decades.
