Wooden 3D Puzzles for Adults Aero Clock - Mechanical Puzzles for Adults, Wall 3D Clock Puzzle with Pendulum Model Kit - DIY Miniature Kit Crafts Gift for Birthday - 320 Pcs

This is the first time I’ve built one of these wooden models, and I gotta say it was super fun. Instructions were pretty clear for the most part and the end result feels like a solid mechanism. Didn’t break anything and got all the strings set up without too much trouble. It looks great, especially when it’s in operation. All that said, don’t expect it to work smoothly without putting in some extra effort to fine tune it. It’s super important to sand all the places that are indicated in the instructions, as well as any gear faces that may pass against the static supports. Especially important to sand the pendulum and escapement gear. The wax included in the kit is tricky to apply properly to the gears, so I got some candles from the dollar store and applied melted wax with a paint brush. That took a bit of time but overall it was enjoyable. I’ve spent a bit of time trying to break the clock in, and so far I’ve been able to get it to go for about 15 minutes before I need to give it a slight nudge. It’s improving quickly with more use though, so I’m feeling optimistic about it breaking the hour mark by the end of the week. Edit: 1 day later and it’s going for more than an hour now at a time now. Didn’t do anything except keep nudging it along to break in the mechanisms. I’d gladly build more of these models if I had the space for it!

Heel mooi. Wel voorzichtig ermee zijn. Ben er druk mee. Fijne tijdsbesteding. Hoge kwaliteit en duidelijke omschrijving. Prima product.

Great kit. Went together well. The balloon was fiddly, but all in all, great fun. And it all worked! The balloon rises, then falls on the hour. It kept stopping and eventually traced it to one of the mounting screws that wasn't fully screwed in, so it twisted the whole clock slightly. Found that 2kg of sand totally filled the weight bag. (dried it well before weighing). The minute indicator has to be turned about 7 minutes cw before the ratchet kicks it when adjusting. The pendulum "weights" could do with finer adjustments to achieve more accurate time keeping, but I'm just happy it all works 😁

I've built quite a few laser cut wood kits (marble races, clock, toys, etc), and this is the best so far. It was a real pleasure to build. The instructions are excellent. After a bit of fine tuning the clock keeps pretty accurate time, with run times of about 19 hours before I need to reset the weight. The wax stick that comes with the kit is not great (and is very small). Instead of hard wax, I used soft furniture wax, which was great for waxing the teeth of all the gears. The one small drawback with the clock is the setup of the faces. They're not easily read from a distance. I've set up 15 minute markers behind the balloon, which makes a fun (but not very accurate) way to read the time from further away. Further note: I have modified the string for the weight, and am now getting run times of 21 hours.
