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. 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!

The media could not be loaded. I bought it for my husband and he loved it.He said it was easy to assemble and the manual is very complete. You have to lubricate very well the scape mechanism so it can work properly (parafin). His clock works for 6-6,5 hours non stopable. Really nice to learn more about mechanical clocks. Best purchase ever.Ideal for 14+ year old.

As to a clock, will keep decent time, spring has an absolute limit of about four hours. Has enough energy to run the pendulum at most two and a half hours. I found the rear axle support on the spring gear set too far back and a bit out of alignment causing the gear to fall off and shorten the run time. I fashioned a replacement out of scrap from the A panel, cut off the top of the original support, and used super glue to attach the replacement to the original. Make sure there is a slight gap to allow the spring to move freely. I considered a second spacer on the front except it would not engage the next gear.On the top three gears and pendulum, adjust the spacers to allow a slight gap on one end not to touch the frame. Otherwise there will be too much friction for the clock to run. You can do the same for all but it is most important for the top ones as the friction will be magnified a hundred fold or more. Some white lithium grease may help on these gears, not needed on th rest.As to demonstrating how mechanical clocks and geared systems work, a most excellent demonstration model, so so on the properties of pendulums.As to building the model, think IKEA instructions. As to gap measurement, numbers accurate, diagrams suggest using a tool that will often give a different measurement. Recommend long nosed pliers, practice first on one of their easier models to get a sense of how to assemble these and work with the material.Update: After running it around fifteen cycles, it seems to be wearing in and running out most of the spring. Last cycle ran four hours and ten minutes. Pretty much reached the theoretical limit.

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.

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 bought a couple of these model kits and they are absolutely wonderful. A great activity to do with kids or your spouse, definitely kills the boredom. Instructions are easy to follow and once they are put together they work! On this one, my boyfriend and I had broken one of the hands to the clock, we tried gluing it back together only to make things worse. I emailed the company to see if there was a way to get a replacement piece, and they are sending me a new kit!!! How awesome is that?! Great product and great customer service. I will be buying more. :)
