Making fire tools for a wood-burning stove: a UK blacksmithing project
A wood-burning stove really only asks for three tools: something to stir the coals, something to pull ash forward, and something to carry it out. Most shop-bought sets are too short, too thin, or sized for an open fireplace rather than a sealed box with a narrow door. Forging your own takes an afternoon, a bit of mild steel and a tape measure — and you end up with tools that actually fit through your door.
Measure the stove before you strike
Every dimension that matters comes off the stove itself, not a catalogue. Before you cut any steel, measure the width and height of the door aperture, the depth from the door to the back brick, and the width of the ash pan recess. Write the numbers on the wall of the workshop.
The shovel blade and the rake head must each pass through the door opening with a few millimetres to spare. Too wide and it will not go in; too narrow and you will be shovelling ash for ten minutes. On most UK stoves, a blade or head of 75–100mm on a 400–500mm shaft hits the sweet spot.
Length matters just as much. A tool that is too short puts your knuckles near hot cast iron. From handle end to tip, 450–550mm suits most stoves, with the last 130–150mm given over to the grip.
Steel, tools and a sensible setup
- Poker: 520mm of 10mm round mild steel, or 8mm if you prefer a lighter feel in the hand.
- Rake: the same round bar for the shaft, plus 20 x 5mm flat bar for the head.
- Shovel: 1.5–2mm mild steel sheet for the blade, round bar for the shaft.
- Fittings: 4mm round bar for rivets, a short length of tube or flat for a collar if you want one.
On the bench: a hot cut chisel, a half-round file, a hacksaw or angle grinder, a wire brush, and a block of beeswax. A 1kg ball-peen and a lighter cross-peen will cover everything here.
One hard rule. Never forge galvanised, plated or painted steel. Zinc fumes are genuinely harmful, and you cannot tell by looking whether a piece of scrap has been coated. If you do not know where a length of metal came from, it does not go in the fire. Work with ventilation, and keep your head out of the smoke.
Forging the poker
- Cut 520mm of round bar and bring one end to a bright orange heat.
- Draw the tip out over about 60mm, then crank it into a small right-angle hook or flatten it into a blunt chisel edge.
- Work the handle end into a hook, eye or small scroll — something your hand can find in a dark firebox.
- For a twist, heat 120–150mm just below the handle, hold one end in the vice and turn the other with a wrench. Four to six even turns over 100mm looks deliberate rather than accidental.
- Let it cool in air.
A sharp spike is the wrong choice for a stove poker. It slides off clinker and scratches glass. A flattened, slightly hooked tip breaks up the fuel bed and drags coals forward without gouging the fire bricks.
Mild steel does not need hardening for stove tools. Quenching a poker gains you nothing and gives a thin section a reason to snap.
The ash rake
A rake pulls ash and unburnt fuel forward without dragging it over the baffle plate. Keep the head 70–90mm wide and the tines short, around 25–35mm.
The straightforward version: forge the end of the shaft into a flat, cranked blade and cut two slots with a hot chisel to make three tines. The neater version: forge a separate head from 20 x 5mm flat, split it into three or four tines, and rivet it to the shaft through a lap.
Either way, bend the head so it sits at roughly 45 degrees to the shaft. Flat to the floor, it pushes ash about. Angled, it lifts and rakes it.
The shovel
Cut the blade from sheet at around 80–100mm wide and 120–150mm long. Forge the edges smooth, then dish the blade gently over a shallow hollow in an end-grain log or a swage block. A dished blade carries far more ash than a flat one, and less of it spills back onto the hearth.
Attaching blade to shaft is the only fiddly part, and you have three options:
- Fold two wings up from the rear of the blade, wrap them around the shaft and rivet through.
- Form a separate socket cone from sheet around a mandrel, rivet it closed, then rivet it to the blade.
- Weld it. Serviceable, though a riveted socket tends to outlast a weld that has been cycled through hot ash for a few winters.
Two or three 4mm rivets are plenty. Peen them cold against the anvil and file the heads flush.
Finishing and hang loops
Wire brush every piece while it is still warm — hot enough that you would not hold it, but well below a glow. That lifts the scale and leaves a grey satin surface. Then rub in beeswax or a beeswax and linseed oil mix while the metal still holds some heat.
Do not paint or lacquer the working ends. Anything that goes into the firebox will burn off, and paint fumes in a living room are thoroughly unpleasant.
Small details worth the effort
Forge a loop or eye at the end of each handle so the set can hang on a tool stand rather than colonising the hearth. Round off every tip and corner before you call a tool finished — a sharp point scratches stove glass, catches under baffle plates and chips fire bricks.
Using and looking after the set
Keep the tools long enough that you never reach over the door with bare fingers, and store them where the handles stay cool. Re-wax once or twice a season, and check the shovel rivets each autumn before the stove comes back into regular use. A loose rivet is a two-minute fix at the bench and a burnt hand if you ignore it.
If you are unsure about your stove installation, what you are permitted to burn in a smoke control area, or whether a modification is sensible, ask a qualified installer or your local authority rather than guessing.
