DIY Charcoal Iron From Scrap Metal and Welding Rod

Have you ever wondered how people ironed their clothes before

electricity reached every household? Charcoal irons date back

centuries — the Chinese were already using heated metal pans

filled with charcoal as early as the 1st century BC to press

fabric. The "box iron" design we recognize today, with a hinged

lid and a hollow body for holding hot coals, emerged around the

15th century and became widely used across Western households

from the 16th to 18th century.

Growing up, I always found these old charcoal irons fascinating —

simple, heavy, and built to last. So when I had some scrap metal

lying around in my workshop, I decided to build one myself from

scratch, the traditional way: a hinge at the back, a latch at the

front, and side vents to keep the charcoal burning — just like

the originals.

This project combines traditional design with practical metalworking

skills: cutting, welding, and shaping by hand. I didn't have access

to CAD software, so the entire design started as a hand-drawn sketch

on paper — just a pencil, a ruler, and some patience.

Total cost? Just $2 for the scrap metal sheets from a local junkyard.

The result is a fully functional charcoal iron that pays tribute to

how clothes were pressed generations ago, built entirely with basic

tools: a hand grinder, a drill, and a 60A welding machine.

Let's get into how I made it!

- 1mm iron sheet (for the body)

- 4mm iron sheet (for the base/sole plate)

- Welding rod (for hinge pin and latch hook)

- 2mm welding rod (for welding)

- Old broom handle, 10cm length, 1.5cm diameter (for handle)

- 2 screws (to secure the handle)

Tools:

- Hand grinder with 4-inch cutting disc

- Hand drill with 4mm drill bit

- Electric welder (60A, 2mm welding rod)

- Welding safety glasses

- Sandpaper (grit 120 and 240)

- Whiteboard marker / Tipe-X (for marking the design on the metal sheet)

Total cost: ~$2 (scrap metal from a local junkyard)

Build time: 1 day

Since I didn't have access to CAD software, I sketched the design

manually on paper, complete with exact measurements for every panel:

front, sides, ventilation panels, base, and lid. I also marked the

hinge hole and latch hole positions, along with the handle placement.

This hand-drawn technical sketch became my main reference for

marking and cutting the metal sheets.

Using a hand grinder with a 4-inch cutting disc, I cut the 1mm

sheet for the body panels (front, sides, ventilation panels,

back, and lid) and the 4mm sheet for the base plate, following

the pattern marked with a whiteboard marker.

For the lid panel, I left two small tabs protruding on each side

— these would later become the mounting points for the hinge pin.

Using a hand drill, I drilled a small hole through each of the

two protruding tabs on the lid panel.

I then took a piece of welding rod, cleaned off the slag, and

welded a small flat metal tab onto each end of the rod — these

act as stoppers to prevent the rod from sliding out once inserted.

This rod was then inserted through the drilled holes on the body

tabs, allowing the lid to pivot open and closed, just like a

traditional door hinge.

To secure the lid when closed, I drilled a small hole at the front

tip of the lid panel using a hand drill.

I then took another piece of welding rod, cleaned off the slag,

and bent it into a U-shaped hook using pliers. This bent wire was

inserted through the drilled hole and welded in place from the

underside, creating the latch hook that will lock into the body

bracket below.

For the body-side latch bracket, I first cut a small L-shaped

piece of metal and drilled a small hole through its protruding

edge using a hand drill.

This drilled L-bracket was then positioned at the front tip of

the body, at the "connection notch" location marked on the S2

panel design, and welded permanently in place. A short piece of

welding rod was inserted through the drilled hole, acting as the

catch point — when the lid is closed, the latch hook from the lid

slots through this hole, locking the lid securely shut.

I welded the panels in this order using a 60A welder with 2mm

welding rod:

1. Front-left and front-right panels (S2)

2. Ventilation side panels (S1, left and right) — these feature

a jagged saw-tooth cut pattern to allow airflow for the charcoal

3. Back panel (B)

4. Base plate (4mm, BOTTOM) welded to the bottom of the body for

heat retention and a flat ironing surface

The handle was made from a section of an old broom handle, cut to

10cm length and 1.5cm diameter. It was mounted onto two metal rods

welded to the lid, then secured in place with screws to prevent

it from loosening or spinning during use.

After welding was complete, I cleaned off the welding slag and

smoothed the joints and edges using sandpaper (grit 120, then

240) for a cleaner finish and to remove any sharp edges.

This project shows that you don't need expensive tools or software

to build something functional and traditional. With just basic

welding skills, scrap metal, and a bit of patience, you can create

a working charcoal iron that connects to the heritage of how clothes

were ironed before electricity.
