Command the Power Train
Marvel at this engineering party trick and have onlookers baffled as you spin the top gear while the lowest ones don’t move at all. Are you harnessing dark magic?
Perhaps, but these days most people call it physics. Alas, no magic tricks here. Just unnecessary yet satisfying engineering that reduces the movement of the gears to near standing still. It’s mesmerising to behold.
Quite the Puzzle-Pin to Behold
Do you dare release the gears? Once removed, this simple pin can only be put back in when all the gears align once more! That’s a 16,384 revolution journey - or maybe more if you forget which direction you started in!
Just like planetary alignment, this rare event can be marked with all the holes lining up and the pin being returned home like a tiny cosmic needle. How many revolutions will you get?
Why Gear Train?
Why not! We were inspired by this little bit of physics, but it’s also amazing to have a real life bit of engineering to hold and interact with. Gearboxes are always hidden away in blocks of metal and shrouded in mystery, or guarded with bright red warning signs ‘DO NOT TOUCH!’.
No longer! Now you can get hands on with how these gears work and feel. We set out to create a satisfyingly tactile, handheld, accessible version of the previously unobtainable. You can enjoy a bit of physics, baffle those who pass your desk, and most of all have some gear-shaped fun.
Torque the Talk
Harness the power of the gears. Simply turn the first gear and watch as your motive effort is enhanced by the power of two by each gear. Feel the torque of each level, and interact with gears like never before.
The Gears Have Aligned
Each part is precision machined using CNC machining, and then hand assembled in our UK workshop. Fuelled by Yorkshire tea and a desire to shine, out team machines each part from solid metal to the same tolerances used in aerospace engineering.
Each part of the Gear Train fits together like a Swiss watch, with perfectly meshed gears for maximum satisfaction. You won’t find any mass manufactured parts here, and while it takes a bit longer it also guarantees quality that lasts a lifetime.
Geared to Perfection
Introducing fidget factor; you won’t want to put this stack down! Keep idle hands busy while you come up with all your best ideas, or get lost in the motion. Gear train is a fidget toy in a class of its own. Like the world-record-breaking Class A4 steam locomotive. That’s a pretty good class to be in.
Do you think this is what fidgeters all around had in mind when they wanted to keep busy? Maybe not, but if you’re going to get fiddly it may as well be with a well engineered mechanism.
Tactile Treasure
Not just designed to be a mechanical marvel, the Gear Train gives satisfying tactile feedback. It feels great to hold, and will greatly please your little mechanoreceptors. As the old saying goes,‘happy mechanoreceptors, happy life’. Or something like that…
These gears are designed to be touched. Each edge has been finished to perfection, so there are no sharp bits or rough patches. When you hold this gear stack, you won’t want to let it go.
Experimental Inspiration
Artist Arthur Ganson created the piece Beholding the Big Bang, an incredible exploration of the estimated age of the universe. A set of gears over a meter long has a motor running at one end, with the final gear set in a block of concrete.
This impossible looking setup was geared down so much that even with the first gear spinning at speed, it would take 13.7 billion years for the last gear to turn. Because of this, it’s possible to anything with the final gear - in Ganson’s case, it’s embedded in concrete! The gear set still runs perfectly, and it’s a great demonstration of the principals of gear ratios and how powerful they can be.
Shiny Steel
Corrosion resistant and tarnish proof, this solid stainless steel construction will stay looking as good as it does the first time you hold it for years to come. They’ll be excavating this thing in hundreds of years and marvelling at its excessive gearing system.
Weighty stainless steel gives that heavy reassurance that it’s well made, and perhaps consistent paranoia of dropping it on your foot. We wouldn’t advise that though.
Breathtaking Brass
Like clockwork mechanisms of old, this design uses brass gears designed to pay homage to those early machines.
The gears will run so smooth that even the Swiss master watch makers will look on in envy. This version has a hard anodised aluminium base, because every handheld fidget toy needs a perfect weight distribution. This makes it more comfortable to hold and the hard anodising prevents any corrosion, keeping your gear train running for years to come.
Locomotion, Not As We Know It
Enhance your power output by 16,384! Each gear doubles your torque input, and you can even reverse the motion using the lower gears in the train and watch the top gears spin out of control.
But are you strong enough to work your way down each gear and harness the full power of the gear stack?
Catch a Train to Satisfaction
Work your way down the line to get different tactile feedback from the torque on each gear. If you fancy a challenge, try turning the sixth gear down! If you just want to sit back and enjoy the ride, engage with the top gear and enjoy your existence in a perfect world of train bliss.
One Hand, Two Hand, Red Hand, Blue Hand
Fidget with one hand, both hands, or have it take pride of place on your desk and use just one finger to twirl your gears! Feeling ambidextrous? Gear train won’t judge! You can use this bad boy with any finger on any hand. You could even use your toes if you’re so inclined.
World’s Strongest Fingers
Turn those gears, and turn your fingers into powerlifters. Working your way up and down the gears gives your fingers a workout, and will gradually train your pinch strength. Soon you’ll be dangling off the Burj Khalifa by your finger tips, and eventually you’ll be grabbing with the strength of a coconut crab. Show those coconuts who’s boss.
Fancy Desk
Have your desk toys stand as a testament to engineering. People will walk by and want to know just what’s going on, and you can tell them all about it. It’s a fidget toy you’ll be proud to display.
Service Please!
You can also take it apart and service it yourself if it needs any help along the way, or maybe you want to challenge someone to put their own gear train together! Either way, your train isn’t going off its tracks any time soon.
Lasting Lifetimes
Like any great steam locomotive, Gear Train will still be turning in 200 years - that’s our guarantee. If it’s not, send it back for a repair or we’ll replace it. We’re confident in what we do, and how we do it. We design like they did in the Victorian era, and we use the best materials we can get our hands on all to ensure this train will keep chugging throughout time.
The product and pictures of the product are different from the one shown in advertisement videos. In the promotional videos you can see both stacks have the same number of gears, 7 each for a total of 14 which would only give you a ratio of 1:8192 and my guess is that they noticed that which led to them adding another gear for 15 total to get to the advertised 1:16384, which is great, however, they could only easily fix this, by adding a gear to the stack that doesn't have the locking pin cause otherwise the locking pin wouldn't fit because it would be to short.
Because the locking pin stack is now 1 gear shorter than the other means that the last gear of that stack has only a 1:8192 ratio, meaning you'd only need 8192 rotations of the top gear to fit the locking pin back.
So for the full gear train experience you'd have to make the bottom gear of the locking stack rotate twice to get the intended 16384 rotations.
Normally I would let this slide due to being a technicality however since MetMo prides itself on accuracy and precision I just can't in this case which is why I'm giving it a 4/5 stars. It's still a fun and fantastic product working (mostly) as advertised.
This is not a too serious review just something that's bugs me, loving precision and accuracy myself.
I am thoroughly impressed with the MetMo Brass Gear Train. The craftsmanship is outstanding, and it truly feels like a premium, well-engineered piece of metal. It's a fantastic addition to my desk and a great conversation starter. Highly recommended for anyone who appreciates precision engineering!
Pretty boring and really rather expensive - what it does is probably not really worth doing and mreley confirms i have too much money to waste. I must try not to make such silly impluse purchases - never again -- hopefully
Another excellent product!!
I found this to be a well engineered item, once picked up it's hard to put down.It took me 50 minutes to complete one cycle and put the pin back in.It keeps your mind occupied while being quiet relaxing.I love it and I'm sure it will last a lifetime.
Well made like everything with MetMo - these gears are fun and stylish. I'm waiting until I have no other things to do in life before I rotate them 16.000+ times back to the start. Thank stars I could tell by looking at it and could go back and reinsert the pin. Also you can disassemble if you really get desperate!!
Shipped 3 weeks ago and still have not received it.
Hi Tom, Thanks for getting in touch, and we're sorry to hear about the delay with your order. Our customer service team is already in touch and working to sort this for you. According to the tracking, your order had been awaiting customs clearance, which has now been completed. We’ll ask our team to follow up with you on this, and your order should be with you very soon.Cheers Team MetMo
It took four months just for this item to be shipped. There was absolutely no disclosure that it would take that long, i wouldnt have bought it if i had known. Seems like false advertising honestly. This company needs to get its shit together. I’d expect better based on the price
Fantastic build quality, with no sharp edges and the gears turn very smoothly. A well designed little device which can be very addictive!
Seems well made , not cheap and ill fitting .
Could be a bit bigger! Or smaller 🤣 It works perfect. And I like the fact that you can take it apart to reset it! Thank you very much!!
Out of 4 Metmo items I have, this is unfortunately my least favorite, despite looking forward to it the most. The whole structure seems a bit wobbly, I think due to only being anchored on one side. That results in a lack of precise alignment which then makes things jam up.
Hey Adam, thanks for your feedback! This was actually an issue identified in some of our earlier batches, and can be fixed by tightening the central rods with a 2mm Allen key. If you're still having any issues with your Gear Train though, please reach out to our customer service team and they can take a closer look. Cheers Team MetMo
Love this x
I love it. It’s great to just fiddle with etc, but after trying to line them up again, they don’t :(6 gears line up, but one gear is totally off kilter. Guess I have to dismantle it and try again. No idea what caused it.
Hey Philippe, thank you for your feedback! We actually found that some of the Gear Trains were arriving slightly loose (possible movement in transit!) and it misaligned the gears. A quick fix to resolve this is to gently tighten the top posts using a 2mm Allen key.If you’re still experiencing any issues, please don’t hesitate to contact our customer service team and they’ll be happy to help further.CheersTeam MetMo
Beautiful engineering and craftsmanship! It feels great to hold and even makes a nice whirring sound when spun on a lower gear. I love the challenges of making a full rotation and disassembling/reassembling.
