UGEARS Sky Watcher Tourbillon Table Clock - 3D Wooden Puzzles For Adults, Wooden Model Kits for Adults to Build - Astronomical Mechanical DIY 3D Puzzle Clock, 3D Puzzles Adult

Great product.not yet built.still in process of removing components fron plywood sheet!!

Was a little concerned on what I was going to get. However, the quality of the product and precision engineering of the parts are incredible. Parts are tight to fit together, but not such that you have to alter them. Can be fidley and some bits a little fragile. Once fully constructed, I was amazed that it "Just Worked". For my next kit (yes I'm hooked now), I will look at better ways to wax moving parts.

well made, but with a few design flaws. The kit is well presented with well lasered wood sheets. Instructions are good but you need to carefully check the views as to orientation/direction of view. I built the kit but would not run. Carefully checked against build instructions and built to the book. 1. I removed one of the spacers (part number 128) on the forks to prevent the locking pin (part number 129) fowling the escape wheel. 2. I replaced the 'toothpick' bearing for the tourbillon cage with a brass pin as this is an area of high friction. 3. I added 2 washers to the tourbillon cage pivet to raise the assembly slightly to prevent rubbing on the circular gear track at the top. 4. I added 4 rollers (made of brass for ease) to stabalise the tourbillon cage. The two wooden ones (part number 166) were to small to keep the cage vertical. Overall, happy with the kit. With the mods, now runs for about 3.5 hours on a wind.

I have not finished this..the plywood is very fragile it can break easy then you got to hope you can glue it back..some warnings about spring was not noted how it can bounce back after winding it and it releases'it snaps back violently so becareful with that..when the skywatcher is completed it is pretty good..its the plywood being fragile you got to be careful of and be sure when putting parts together you have correct parts in each step ant put together correctly you make a mistake and attempt to take something apart the plywood could easily break so be careful

This model is quite fiddly to assemble, but do it carefully and it works really well, and is actually quite accurate. It's obviously not meant as an actual clock, but as a novelty piece, it is excellent and extremely interesting. I had to add some ptfe spray in one or two places to aid the moving parts, but it ran for hours before I actually decided to stop it. Highly recommended!

Looks as if the parts are well cut and it should be fun to make up.

Read the instructions safty is to be observed. This was very enjoyable to do. The outcome is good. SAFTY FIRST watch the main spring do not release the lock until you put the head on. I almost took the end of my thumb off. When finished the clock was working after a bit fiddle, not much if you follow the instructions. I was patting myself on the back and found the dials were not moving. Had to strip down and found part 21 had broken. I am now waiting for UGEARS to send me a new part. found takes few months to get spare parts but they came. At the minute with the war they take a little longer as I had to send for spares for other puzzles but they still come. You are informed when dispatched and its free great service.

Very disappointed that this is sooooo hard to get it to work, rebuilt 4 times but looks like it’s a great paper weight Followe videos etc but still no joy, Sorry Ugear but don’t work for me Good luck who ever buys it Denis B

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.

El producto es lo descrito y es lo que se espera. Muy entretenido y relajante de hacer. No esperes una carga de días, solo durará unas pocas horas (4-6h). Pero es para lo que es, entretenimiento y tener una cosa curiosa.

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

It's a really amazing model. You just need to lube everything, and it's probably best to use solid silicone wood lube instead of a paraffin stick. Even so, it will only work for a few hours at most. Still, it's amazing that it does. I've built many of their models, and this one is way above the others in terms of mechanical design. Somebody over there really had to know a lot about clock mechanisms. The design itself is really something, not just for a puzzle but in general. As an engineer, I could imagine designing some other models, but I would have no idea where to even start with this one. It's probably not for young kids. Setting it up so it works takes a lot of time itself. I'd say, this is more of an adult kit. (patience) Now I want a real clock like this, made out of metal...
