Cowley Double Drive vs Kiln Crafts Thistle: Which Pottery Wheel Is Right for Your Studio?
The Cowley Double Drive (£1,650 inc VAT, seat included) is a classic British-designed pottery wheel with a unique cone-and-ring drive mechanism — built for reliability and favoured in UK studios for decades. The Kiln Crafts Thistle (£1,699) is a modern UK-designed direct-drive wheel with a Hall-effect foot pedal, built-in USB charging, and a 30-day home trial. They're £49 apart in asking price and a generation apart in drivetrain design. Here's how they compare across every spec that matters.

The Price Question: Which Is Actually Cheaper?
At £1,650, the Cowley looks £49 cheaper than the Thistle's £1,699. But the comparison isn't quite that simple. The Cowley's price includes a thickly padded seat — a meaningful addition, since a separate pottery stool is typically an extra cost for any wheel that doesn't come with one. The Thistle is sold as a wheel only, so if you need a stool, add that to its price.
On the other side: the Cowley's delivery is calculated at checkout and is not free. The Thistle ships free anywhere in mainland UK. For a 36kg wheel, delivery adds a real cost to the Cowley's total. On a landed-price basis, the two wheels are very closely matched — but the Thistle has the cleaner, all-in price.
Drive System: How the Cowley "Double Drive" Works
The Cowley's drive mechanism is genuinely distinctive. Rather than a belt or a direct motor-to-shaft connection, it uses a spherical cone driving a synthetic drive ring, with further reduction in gearing. This is the "Double Drive" of the name — a two-stage cone-and-ring friction system that delivers the torque needed for throwing. It's not belt drive, and it's not direct drive; it's a design that has been refined over many years and has a loyal following among UK potters.
The practical characteristics of the cone-and-ring system: smooth, responsive speed control; good low-speed torque; and a distinctive feel that experienced Cowley users often describe positively. The trade-off is that friction elements — like any wear surface — will eventually need attention. The synthetic drive ring is a replaceable component.
The Kiln Crafts Thistle uses an 800W direct-drive motor. There are no friction elements, no belt, and no gearing between motor and wheelhead. Torque is delivered directly at every speed. There is nothing to wear out in the drivetrain — the motor shaft IS the wheelhead shaft. In practical terms: the feel is consistent from the first session to the thousandth, and long-term maintenance is minimal.
Centering Capacity & Wheelhead
The Thistle has a 25kg centering capacity and a 320mm (12.6") wheelhead. The Cowley rates at 20kg with a 280mm (11") wheelhead. On both measures, the Thistle has more working capacity — 5kg more centering and a 40mm wider working surface.
For most studio potters, 20kg is generous — it comfortably covers decorative vessels, large bowls, and ambitious production runs. The Thistle's extra capacity and larger wheelhead won't be decisive for most buyers, but if you regularly work at the upper end of single-throw weights or use large bats, the Thistle has more room.
Speed Range
The Cowley runs 0–240 RPM; the Thistle reaches 0–300 RPM. For throwing and centring, the difference is negligible — most throwing happens well below 200 RPM. For trimming, decorating, and faster surface work, the Thistle's 60 RPM extra headroom is occasionally useful. Neither is a deciding factor for most potters.
Foot Pedal
The Cowley uses a mechanical foot pedal — a well-established design that gives functional speed control across the range. The reverse switch is a standard rotary control rather than a foot-operated function.
The Thistle's Hall-effect foot pedal is contactless: speed position is read magnetically with no physical wear components. The feel stays identical after years of throwing — no dead zones, no gradual drift in calibration, no contacts to clean or replace. For potters who spend long sessions at the wheel and want precise micro-speed control, the Hall-effect pedal is a meaningful step up.
Studio Footprint
The Cowley's overall dimensions are 1030 × 530mm (length × width), which includes the integrated seat. The Thistle's wheel-only footprint is 60 × 65cm, with adjustable legs (40–65cm working height). Both wheels weigh almost identically — 36kg vs 35kg — and are comparable to move. If you're setting up in a compact studio, factor in that the Cowley's seat extends its effective length significantly.
Warranty & Buying Experience
The Cowley Double Drive carries a 2-year limited warranty — year one covers parts and labour; year two covers parts only. Importantly, transport costs for warranty claims are borne by the customer, not Potclays. If you need the wheel collected for a second-year repair, that's an additional cost on top of the wheel's price.
The Kiln Crafts Thistle has a 3-year warranty, one year longer, and comes with a 30-day home trial — you can use the wheel in your own studio for a month and return it if it isn't right for you. There is no equivalent trial when buying the Cowley through Potclays. The Thistle also ships free anywhere in mainland UK in 2 working days; the Cowley's delivery is calculated at checkout.
Who Each Wheel Is For
The Cowley Double Drive is a strong choice if you want a wheel with a well-established British design and a distinctive drive feel that experienced Cowley users value. The included seat adds real value, and the price-with-seat is competitive. If you're drawn to the Cowley's proven heritage or the particular character of its cone-and-ring drive, that preference is entirely valid.
The Kiln Crafts Thistle makes sense for potters who want a modern direct-drive wheel with maximum long-term reliability, a larger wheelhead, higher centering capacity, a Hall-effect pedal, and a 30-day home trial — at a price that, once delivery is factored in, is closely matched to the Cowley. You get more modern technology, a longer warranty with better terms, and a stronger buying experience.
Verdict
The Cowley Double Drive is a genuinely good wheel — a classic British design with a loyal following and a unique drive mechanism. If you want a wheel with heritage and a seat included in the box, it earns serious consideration.
For most potters weighing up the two, though, the Kiln Crafts Thistle offers more: a larger wheelhead, greater centering capacity, an 800W direct-drive motor, a Hall-effect pedal, a 3-year warranty with better terms, free delivery, and a 30-day home trial. At comparable landed prices, the Thistle's technology and buying experience make it the stronger purchase for the majority of studio and home potters.
