Little hard to assemble and tune properly. Worth every penny when works.

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.

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.

A great kit, yes it’s tricky, yes it may not fully work if you do it wrong, clocks are a feat of math and engineering, anyone expecting more than a semi functional model is not understanding what goes into a real timepeice. For what it is I loved it, in fact I will make another but decorate this time. It’s not for the feint of heart or beginner yes, however! Anyone can build it if you can follow a picture instruction book and have good glasses. Not all will get it working. Time to build of 11 hours they say, yes I agree. You need to sand, wax and smooth parts for nice low friction movement. If you just pop out the parts, put them together it could take 3 hours too. It will not work and then you will give it less stars. So this where the advanced builder comes in. Advanced builder will take their time and make a nice model that functions at a basic level. For the impatient builder you will still achieve a nice model that will not function for long. Think what type of builder you are and expect the result that you put in. The kit: Read the instructions Read the instructions again Follow the instructions (mainly for us men who believe manuals are for putting your cups on) Very well laser cut, did not need a knife in my case Get more wax and check out YouTube on how to wax cogs Wax the cord Buy good sandpaper and smooth all parts for low friction movement Sand all cut edges where you can, the laser leaves joins to keep it framed in transit, these need removing Have patience The correct weight will be important in the bag, try lead shot rather than sand Weight on the balloon counterweight is also important to slow down the balloon drop when running. Test each cog as the kit comes together for friction and movement Make sure you hang on the wall to complete, if you try to build first, hang later you will tangle your cords and lines It’s a model clock, please do expect to get the correct time after 5 minutes of use It’s also quite sturdy once built Have fun building it, that is the overall aim, it’s a great achievement no matter how far you get. Sorry! It’s a long review but I found it a great model to work on and looks good on my wall
