Ugears - Aero Clock
The Aero Clock isnt just a 3D wooden mechanical model is an educational toy and a pretty showpiece. The Ugears Clock is an actual working clock that you can build yourself, mount to a wall, wind up, then watch as the seconds, minutes, and hours tick by. The Aero Clock is an ingenious puzzle and DIY Stem kit clock mechanism, unlike any other clock. It is a lovely piece of precise engineering that reveals the workings of a weighted pendulum clock to builders and viewers alike. Like all Ugears models, it also has that extra touch of whimsy, to captivate and charm our growing legion of fans. As you build the Aero Clock, a wooden wall clock with a pendulum, you will learn the basic principles behind clockworks, how the steadying influence of a swinging pendulum operates through a rocking anchor, locking and unlocking the gears on an escapement one second at a time, thereby regulating the (slow) descent of the weight as it drives both power gears and timekeeping gears. The Ugears Aero-Clock with a pendulum is a marvelous puzzle and the perfect family project. When you work together to assemble this DIY wooden clock model kit, you will experience the satisfaction of building something together and not just any model, but an actual functioning timepiece. Afterward, youll have a beautiful object for the home, something your family can enjoy together as time goes by. How are STEM toys a smart way to learn?

I got this clock kit for Christmas and thoroughly enjoyed assembling it. The problem, as I saw someone else mention, is that it doesn't work. Well, at least, it won't go for longer than an hour at most (usually it lasts 1 - 5 minutes, after I jiggle it or realign the cogs). I've spent so much time watching troubleshooting videos and making tiny little adjustments and I still can't get it to sustain operation.I believe the issue is that the frame isn't sturdy enough to keep the main cogs properly aligned, and after time they bind up and stop. The front panel that holds the clock dials to the backing cogs kind of leans forward, and after a time, the cogs start to wind crooked and the clock stops. Sometimes just pushing the front panel forward gets it ticking again ... MoreI got this clock kit for Christmas and thoroughly enjoyed assembling it.

I've spent so much time watching troubleshooting videos and making tiny little adjustments and I still can't get it to sustain operation.I believe the issue is that the frame isn't sturdy enough to keep the main cogs properly aligned, and after time they bind up and stop. The front panel that holds the clock dials to the backing cogs kind of leans forward, and after a time, the cogs start to wind crooked and the clock stops. Sometimes just pushing the front panel forward gets it ticking again (for a few minutes).In desperation (because I really want it to keep ticking - it's so lovely when it's working), I took it off the wall and used wood glue to bind the loose joints. When the clock is ticking, the frame starts to loosen at the joints and I thought maybe tightening the frame would help minimize all the cog shifting it's been doing. It seemed to help a little at first, but now when I look at the clock from the side, I can see that the main cog at the bottom has two problems: it's extremely loose on it's wooden axel and easily becomes crooked, and I think tinkering with it so much (or running it so long loose like that) has caused that cog to become visibly warped.So, my final conclusion is that it's a beautiful thing to have up on the wall, but I've realized that wanting it to actually keep ticking is too much to ask. I thought about buying another one (maybe mine was machined on slightly flawed wood, perhaps?) but just saw another reviewer saying he had the same problem with two kits, so I guess I won't do that. Makes me sad, because I think it's a work of art. It looks great mounted up on the brick column we have, and would be thrilling if the thing would just keep ticking.

This clock is fantastic. The build was fun, but not too difficult. There are a lot of reviewers saying the clock is not functional, but it definitely can be! The instructions do make a few steps a little ambiguous. Watch the troubleshooting steps video if your clock doesn't continue to run. I had to sand the sides of the pendulum pivot to get the clock to continue to run. Make sure it will run continuously with the balloon disengaged before attempting to get the balloon working. I had to add a little bit of weight to the carriage car to keep the line routed correctly. I wound up not using any extra weight on the balloon counterweight. The clock doesn't keep exact time, and being made of wood, temperature seems to affect it. Mine runs fast (about 1 minute per 2 ... MoreThis clock is fantastic.

Mine runs fast (about 1 minute per 2 days), but it's definitely good enough. I have to rewind it twice a day, because it'll only go 22 hours before the sand bag hits the ground.

I bought this clock without reading the reviews. I just thought it looked cool as all get out and I had to have it. I am in no way an “advanced” builder but I do not like to give up. So that being said and putting commen sense together it’s a clock. Clocks usually take some kind of precision. Well to my realization there’s precision in every part of the clock and the fact that it’s wood doesn’t really help at first. So I have not yet gotten the ballon to work but that will come. I have figured out the once built it needs to kinda settle in so it’s not going to 100% work at first. Keep trying to keep it going. For the weight I used pea sized gravel. Getting the weight just right is important because if it’s to heavy the gears will bind if it’s to light the gears will ... MoreI bought this clock without reading the reviews.

If your an inexperienced builder like myself just keep plugging away at it it’ll pay off in the end.

the kit is difficult to deal with since some of the assembly is required when it is mounted in place, couldn't mount it in the workshop. Some of the instructions are color coded with no idea what the coding indicates. The routing of the cables are not very clear. All in all it was fun to build but because of the above mentioned issues and the rickity design I have not gotten mine to run more than a few seconds at a time.
Second unit I buy and both were a disappointment! The clock and design are beautiful. Although the instructions are mediocre at best, I had a lot of fun building specially the second time. The clock holding mechanism and self level are too flimsy to hold the weight of the 2.2 kg counterweight. Buy for the beauty do not expect it to work! I still haven’t gotten my second unit to tick tock!
The clock is really cool. The engineering is superb. The manufacturing is great. The instructions are mostly good but could use some text at times. Pay close attention! I suggest you use the U-Tube videos to supplement them. They also offer product support.
The neighborhood knows we have a Muzeum of all 1000's of different things, including many 3D Puzzles. I was given your Grand Prix car and what a great project. I am 78 years old and it probably took me longer than some but it was fun watching the progression. The vehicle is very precise and an amazing adventure and I will be buying more UGEARS. Paul
The clock was great to build and try to get working. Problems are , theres to much friction even with waxing the shown parts so it keeps stopping and unable to get it slow enough to keep time. Also the bit withe balloon drop doesnt work when connected as it just stops the clock. Looks great though!!
As a career woodworker/furnituremaker, the dead precision of the cut components is astounding. The illustrated instructions are easy to follow and snapping the components together is very satisfying
Ugears are the best and most innovative of all the wooden mechanical toy makers precise Laser cutting superb instructions they may not always "Work" as such but are great to look at
