ROKR 3D Wooden Puzzles DIY Clock Kits for Adults to Build Wood Model Building Kit Unique Birthday Gift Pendulum Clock

The media could not be loaded. Very nice way to pass some lazy afternoons. We bought several Rokr kits . But this is by far the best. The satisfaction of having a working clock at the end of several hours of build time is epic!Some tips: take the time to same and burrs out of the gears. There are not many but it’s worth the extra time.Also, spin each gear on its spindle to be sure it’s not too warped. I had one that seemed warped but it was actually the smaller gear attached to it. There were extra gears which I used to even out the wobble.Wax only the gears the tell you too. I used a lighted Glade candle for the wax , then after waxing I used a hair dryer to remove/ melt the excess wax, repeat the process , and then Hit the timing gear and pendulum again with the hair dryer.One error I did note: on the main spring gear, the tabs stick out behind the gear and the spring can get hung up on the tabs protruding out the back. I sanded then down so the back of the gear is smooth and the spring will not get caught up on the tabs.It was easy to see this was a problem when you let the gears fly without the pendulum , you could see the spring bump when it hit the tabs.....Level the clocckI currently have it running on about 3-4 hours of accurate time. Some more fine tuning should help it work for the full wind.

These models are always fun to assemble and the directions are thorough.At first, my unit would stop after five seconds. I tried sanding all the teeth on the pendulum gear but it didn't help. I removed the pendulum, which is the last piece, and clock worked great although super fast. I noticed the pendulum assembly had a lot of play. I placed some wood glue on all the joints on the top of the pendulum. After drying and placing the pendulum back in the clock, it works great!! As I suspected, the loose joints in the pendulum was taking too much energy out of the swing.

This kit was a lot of fun to put together. I would recommend it to anyone who likes model kits, and especially mechanical engineering.The Good:The pieces were easier to pop out than I anticipated. Final assembly was also easier than I thought considering how many gears and axels there are. The entire thing looks pretty nice out of the box with no tools needed, nor modifications. It's pretty fun to watch the clock go. I was skeptical how well it would keep time, but it remained surprisingly accurate for over an hour.The Bad:The clock sometimes stops randomly. The pallet fork gets stuck on either side, so it's not something I could easily fix with the included leveling pieces. It might be a drive train issue, which is somewhere between difficult and impossible for me to fix. Taking the pieces out and assembly will almost assuredly cause sore fingers. Use the included wooden tool and scrap pieces to help spread out the pressure. Mistakes while assembling the axels are very difficult to undo. The assembled gears on the axels were sometimes wobbly and I don't know what I could have done differently to straighten them out.The Ugly:The instructions don't always do a good job of explaining what is important or how a step will affect future steps. It also would have been nice if the instructions had a section for suggested modifications, such as using wood finish or paint on some parts. The English in the instructions is sometimes a little unclear, which is understandable considering it is a Chinese company. The hands are very difficult to see at a glance, which is not ideal if you want to use this as a primary clock.Overall I would recommend this as a mechanical model kit, it's fun to assemble and it looks cool. I would not recommend it as a clock, since mine stops randomly thereby making it unreliable.

the only problem was a couple of gears were bent , and clock won't run

The media could not be loaded. Ok, so this was REALLY fun to build. It took me about 1 hour and 40 minutes. Each cog wheel in the clock has a very similar build so take your time on the first two and you'll breeze through the rest. After those are built, the rest is magic.. It's SO fun to see everything come to life. My use for this product was very specific.. I actually ended up removing the pendulum and spray painting everything gold and stuck the whole thing in the casing of an old grandfather clock as a prop for a set. (in place of the pendulum I added a small motor because I needed an illusion of time for my project).The wood quality is FANTASTIC. It's easy to pop out each laser etched wooden puzzle piece from the wood sheets they arrive in. The instructions are very, very straight forward. Nothing to read, just clear illustrations (clearer than IKEA's) . Take your time, give in to any perfectionism you have, have fun, and you'll have a stunning and satisfying piece of art to display!

I bought this for my son as a gift and we had fun assembling it together. However he was very disappointed when it didn't work at the end. The pendulum kept getting caught. It's very very important to get it just right and the directions don't help. The directions say no glue required and the pendulum bob loses inertia when swinging due to the parts having a little give, so to fix this issue you need to glue parts D1 D3 D4 D7 and D8 together and make sure that D8 and gear C5 are perfectly centered on each other. After this and it worked fine. After wind up you'll get approximately 3 hours of time keeping then you'll need to wind up again.

I've built some of these before. It's really fun. And I'll be buying another...

It looks great. My child who got it for Christmas just hasn’t had time to build it fully yet. We did see a built sample in a specialty toy store (for $55) that looked really nice. I think it will be great and I think it will be more useful than her typical build it and forget it models.
