Torque The Talk: The MetMo Gear Train

There is something undeniably primal about the satisfaction we get from mechanical movement. In a world increasingly dominated by touchscreens, haptic feedback engines, and digital simulations, the raw, tactile clunk and whir of physical gears feels like a return to sanity.

We have long championed the “desk toy” here at The Coolector, but to label the latest creation from the British engineering wizards at MetMo as merely a toy feels somewhat reductive.

It is a lesson in physics, a sculpture of torque, and a challenge to your patience all rolled into one. Enter the MetMo Gear Train, a device that promises locomotion, but not as we know it.

The concept behind the Gear Train is delightfully simple yet visually baffling. It is a handheld gear reduction unit that fits comfortably in the palm of your hand, yet it packs an exponential punch. The mechanism features a stack of precision-machined gears that create a reduction ratio of 16,384 to 1.

What does that mean in practice? It means you can spin the top gear as fast as your fingers will allow, and the gears at the bottom will appear entirely motionless. It looks like a glitch in the matrix or a feat of dark magic, but it is simply—and beautifully—physics in action. Each gear in the stack doubles the torque of the one before it, letting you physically feel the power build through every level.

It transforms hidden engineering into a mesmerising, interactive experience, taking the internal workings of a gearbox out from behind the “DO NOT TOUCH” warning signs and placing them directly into your hands.

MetMo has released this mechanical marvel in two distinct flavours to suit your aesthetic (and budget). For the purists who love a warm, vintage industrial look, there is a Brass version available for £99. If you prefer something a bit more clinical and modern, a robust Stainless Steel variant can be yours for £148.

Both are CNC-machined from aerospace-grade metals and hand-assembled in the UK, ensuring that this isn’t a throwaway plastic gadget but a solid companion built to last for generations. The weight and finish of these metals add to the “fidget factor,” making it nearly impossible to put down once you start spinning.

But the Gear Train isn’t just about watching wheels turn; it’s also a puzzle. A removable pin holds the stack together, and daring to pull it out initiates a challenge that might take you hours to resolve.

The pin can only be reinserted when all the gears align perfectly once more—a rare cosmic event that requires a full 16,384 revolutions of the input gear. It’s a journey that tests your persistence and offers a deeply satisfying “click” when the planetary alignment finally occurs and the needle returns home.

We often talk about “fidget toys” as mindless distractions, but the Gear Train is in a class of its own—much like the world-record-breaking Class A4 steam locomotive it shares a name with. It is designed for physicists, engineers, and anyone who appreciates the “why” of how things work.

It allows you to command the power train, baffling onlookers as you spin the top gear furiously while the bottom remains stoic and still. It is unnecessary engineering at its finest, a celebration of torque and tactile feedback that proves, once again, that the best things in life are often the ones you can hold, spin, and marvel at.
