Building a chariot requires assembling four main components: a pair of spoked wheels, an axle, a lightweight platform (the box or basket), and a long draft pole that connects to the horses. A typical two-horse chariot measures roughly 2 meters (about 6.5 feet) wide and 4 meters (about 13 feet) from the back of the basket to the tip of the pole. The construction process centers on woodworking skills, particularly steam bending, joinery, and careful wood selection for each part.
Choosing the Right Wood
Different parts of a chariot face different stresses, and ancient builders chose their wood accordingly. The wheel rims (called felloes) and the crossbar of the frame need hardwood, since they bear the most impact and need to resist damage from rough ground. Black walnut or a comparable dense hardwood works well for these structural pieces. The same goes for the wooden dowels and pegs that hold the wheel together, since they’re critical to the wheel’s integrity.
The draft pole, which runs from the basket forward to the horses, also benefits from a strong, slightly flexible hardwood that can absorb shock without snapping. Ash and elm were historically popular choices for poles and bent components because they combine strength with flexibility. For the hub (the central block of the wheel) and the spokes, you have more latitude. Softwoods like cedar can work for parts under less direct stress, though hardwood makes every component more durable. If you’re building for actual use rather than display, stick with hardwood throughout.
Building the Wheels
The wheels are the most technically demanding part of the build. A functional chariot wheel is roughly 1 meter (about 3 feet) in diameter, with spokes radiating from a central hub to an outer rim. Ancient wheels used four to six spokes, while later designs used eight or more for added strength.
Start with the hub: a thick cylinder of hardwood, drilled through the center to accept the axle. Cut mortises (rectangular slots) evenly around the hub’s outer edge to receive the spokes. Each spoke is shaped with a tenon on both ends, one fitting into the hub and the other into the inside of the rim.
The rim is where steam bending comes in. You need to soften the wood enough to curve it into a circle without cracking. Place your rim stock into a steam chamber and bring the temperature to at least 212°F (100°C). Steam the wood for about 15 minutes per quarter inch of thickness. For a rim piece that’s one inch thick, that means a full hour of steaming.
Once the wood is pliable, you bend it around a circular form. This is not a solo job. Historical reconstructions at Brown University found that bending a half-wheel section required four people: two bracing the form, one clamping the wood as it curves, and one doing the actual bending. A bending jig with a steel strap on the outside of the curve prevents the wood from splitting during the process. The strap compresses the outer fibers that would otherwise crack under tension. You’ll likely need to bend the rim in two halves and join them, since bending a full circle from a single piece is extremely difficult.
Once the rim sections are dry and hold their shape, drill holes on the inner face to accept the spoke tenons. Assemble the wheel by fitting spokes into the hub, then attaching the rim. Secure every joint with hardwood dowels and hide glue.
Constructing the Axle and Platform
The axle is a single straight beam of hardwood that spans the full width of the chariot, with both wheels mounted at its ends. It needs to be strong enough to support the weight of the platform and one or two riders while absorbing the shock of uneven ground. A round cross-section works at the ends where the wheels mount; the center section can be squared off for easier attachment to the platform frame.
The platform, or basket, sits directly on top of the axle. Its frame is a simple rectangular structure made from hardwood rails joined at the corners. The floor can be made from planks or, for a lighter build, from woven leather straps stretched across the frame. Ancient chariots used this woven floor as a form of suspension, since the leather flexed over bumps instead of transmitting every jolt to the rider.
At the front and sides, attach a semicircular guard wall about 1 meter (3 feet) high. This can be a light wooden frame with rawhide or wicker panels. The back is left open so riders can step on and off quickly. Keep the basket as light as possible. Chariot performance depends on minimizing weight while maintaining enough structural rigidity to hold together at speed.
Shaping the Draft Pole
The draft pole is a single long beam, roughly 2.7 meters (about 9 feet), that extends forward from the basket to the yoke that sits across the horses’ shoulders. It has a square cross-section for strength and is curved upward from the underside of the basket to the height of the yoke. This upward curve keeps the pole from dragging on the ground and positions the yoke at the correct height on the horses’ necks.
The curve can be achieved through steam bending a naturally straight piece, or by selecting a piece of wood that already has a natural curve in the grain. Using wood with a natural curve is stronger, since the grain follows the shape rather than fighting it. The maximum stress on the pole occurs about 2.3 meters from the front end, near where it meets the basket, so this section needs to be the thickest.
Reinforce the connection between the pole and the basket with a pole stay: an L-shaped brace that runs from the draft pole to the front of the basket frame. Between the pole stay and the draft pole, lash leather thongs or wooden braces in an arched pattern. This creates a truss-like structure that distributes the pulling forces across a wider area instead of concentrating them at a single joint.
Reducing Friction at the Axle
A chariot wheel spinning on a bare wood axle will grind, overheat, and eventually seize. You need lubrication between the hub and the axle. Ancient builders solved this with animal fat (tallow), which was the standard axle grease for thousands of years. By the time of the Roman Empire, builders had moved to more refined options: greases made from calcium salts mixed with olive oil, essentially an early version of calcium grease still used in modern machinery.
To keep the wheel on the axle, fit a wooden or metal pin (called a linchpin) through a hole drilled near the end of the axle, outside the hub. This prevents the wheel from sliding off while still allowing it to rotate freely. If you have access to basic metalworking, a bronze or iron sleeve inside the hub and a matching sleeve on the axle end will dramatically reduce wear and extend the life of the wheel.
Final Assembly
Start by mounting the basket frame onto the center of the axle. Lash or bolt the frame rails to the axle so the platform is stable but the connection has slight flex. Attach the draft pole to the front of the basket, running it forward and upward. Install the pole stay and its reinforcing braces. Mount the wheels onto the axle ends, grease the contact surfaces with tallow or a similar fat, and secure each wheel with a linchpin.
At the front end of the draft pole, attach a yoke: a horizontal crossbar shaped to sit across the necks of two horses. The yoke connects to each horse with leather straps and padding. The entire pulling force of the team transfers through the yoke, down the draft pole, to the axle and wheels.
Before hitching horses, test the rolling resistance by hand. Push the chariot across flat ground and listen for grinding or wobbling. The wheels should spin freely and track straight. Any wobble means the hub bore isn’t centered or the axle ends aren’t uniform. Fix these issues before adding the dynamic stress of horses at speed, since a wheel failure under load can be catastrophic.
