UGEARS Tourbillon Table Clock - Sky Watcher 3D Wooden Puzzle Mechanical Kit - DIY Desk Clock for Adults and Kids

Interesting and challenging project. Great fun and educational at the same time.

Background: This is the second UGears model that I have assembled and just like the first one (Steam Locomotive U-460), the plywood quality felt very good and hefty and the engineering put into the model was very impressive. I purchased this clock thinking that all the lessons I learned from building the Steam Train would make getting this clock smoothly functioning in a jiffy. I was extremely wrong in this assumption. Assembly: My kit was missing the cardstock for the clock dials, but I contacted UGears's customer service and they mailed me the parts to me with no charge. Very nice! It took me 3 days to assemble since I spent the time to wax and sand for a soft finish on every surface (it is imperative that a 90 dollar kit should look and feel good). The build was very complex but satisfying to engage with. I however do recommend buying your own set of quality round toothpicks as I found the ones provided to be of quite low quality. Also, consider buying own your supply of paste wax as you will need a lot more wax than what the kit provides. The instructions for installing parts were clear, though I had to look online to understand some of what was happening when it came to the moving/calibration steps - the descriptions there were a bit lacking. Fortunately a QR code in the manual pointed me to videos that I found helpful. Tuning: It was daily process of fiddling with the tourbillon to figure out what needed sanding or further lubrication. After assembly without tuning, the clock would run for a minute at a time before seizing - which wasn't up to my standards. Learning how the mechanism works before fiddling with it and sanding down actual geometries is vital for not bricking this expensive puzzle. I did craft some parts myself, such as a cleaner pallet lever with lower friction gems and a longer guard pin essentially get near perfect performance. It runs as advertised now, keeping up power for 2ish hours before stopping. I am now extremely familiar with the Swiss lever escapement mechanism. If I had some final tips - it would be that friction is the enemy, and always know how things work before deciding to make permanent modifications. Conclusion: This is a very nice kit and the plywood is of good quality. Costumer Service was helpful in proving me with missing parts and had a fast response time. The toothpicks and wax provided are insufficient in quality and amount so it would be best to purchase your own. The Clock is unlikely to work well right after assembly and will require to be taken apart for further tuning. Perfecting the clock is time consuming process and requires a passing level of knowledge or mechanical intuition but doing so will result in a clock that runs as advertised. I recommend this to anyone with a passing interest in these sorts of things and the patience to back it up.

Todo bien. No es difícil de hacer y pasas un rato entretenido. La pena es que el reloj no funcione las 24 horas, si fuese así se acabarían desgastando las piezas

初めは長く動かなかったけど、しっかりメンテナンスしてら動くようになりました。 付属の蜜蝋が塗りにくくて塗りやすい部分しか塗らなかったら15秒ぐらいで止まっでしまうので、別で蜜蝋クリームを購入して塗り始めましたがなかなか塗るのに手こずりました。 その時、歯車という名前で閃きました。 歯車というぐらいなのだから歯ブラシを使用してガシガシ塗り込んだ所、止まらなくなりました。横回転させる部分の軸受け回転部と下部構造の溝の深い歯車にしっかりと塗り込んだ所、現時点で5分以上止まらなくなりました。（稼働時間確認中） 潤滑は大切です。

Very nice piece of mechanical artwork, I finished it in 2 days, was difficult to make it work properly, but I was able to "break-in" sand-off the edges of the gears to reduce the friction and other form of movement restrictions. I've put some lithium based grease with paraffin wax and it work decently well. It looks cute !!! *You need to lightly sand the edges of the gears with a nail polishing file and properly lubricate them, to reduce the friction between the meshing teeth.

Ugears è una marca fantastica per puzzle 3d in legno, quindi andate sul sicuro. Difatti questo prodotto è davvero ben fatto, bello e funzionante. L’orologio è di media difficoltà e le istruzioni sono chiare e facili da interpretare (attenzione che in due punti dei numeri sono invertiti, ma basterà vedere le immagini a colori per rendersene subito conto). Le altre accortezze sono: nonostante i pezzi vengano fatti con precisione e siano difficili da rompere, siate delicati nel rimuoverli dalle assi. Con la giusta manualità e dopo qualche esperienza, sarà sempre più facile. Infine, il punto più importante, per prodotti meccanici che devono girare a lungo (circa 5 ore) come questo, è necessario passare sui pezzi (specie su quelli indicati nelle istruzioni) la carta vetrata per rimuovere eventuali schegge e, soprattutto, è fondamentale una buona lubrificazione. La paraffina fornita, per me, è davvero troppo poco. Da tempo uso una normale vaselina bianca grassa, che adopero con un pennello. Questo rende, come vedete dal video, i meccanismi estremamente fluidi. Senza questo passaggio, al 90% l’orologio durerà pochi secondi / minuti. Buona costruzione!
