If you have experience with building scale models, then you shouldn't have any trouble with this, and they do include QR codes at a few points in the instructions for online videos to show how certain parts go together. Total build time is about 8 hours.In addition to the tools and parts included, I would also recommend a sharp hobby knife, tweezers, and either fast-setting wood glue or a superglue which works on wood... while the parts all go together well, some need a little reinforcement. Just be warned that some parts are more fragile than others, so be very careful when removing parts from their sheets.It's a good build, working from the base on up, separated into sections - the 'elevator', the whole gearing mechanism (you need to see the eccentric gear at work raising and lowering the elevator - some very nice engineering there), the ball path tower, and the multiple path platform. Section by section, and it all fits together. I would definitely suggest using the wax they include as they show to avoid friction between the woon parts, and to make it all smoother. Also, make sure that the ball at step 5 is firmly pressed into its 'basket'... you'll understand its purpose as a counterweight and a path blocker once the build is finished.The only addition I would make to the build is step 41 - take a piece of narrow scrap from one of the wood sheets and glue it on top of piece F12, about an inch long, from the corner and along the long side of the piece... if the ball is moving fast enough, it might actually jump over the rail formed by F12.Overall it's a fun build, and watching the elevator - and the upper gear - at work is fascinating. I would recommend this to someone who enjoys building and mechanisms, or as a gift for the same reasons.
It is a gift for my husband’s birthday, so I still don’t know how the assembly process will be and if they are really fine pieces or difficult to assemble, when he has the gift and starts to assemble it I will tell you his impression about it. So far, I like the box and the image printed on it, plus the information I’ve gotten from other people who have bought and put it together.
This is my first purchase of this type. Great project piece. Parts snap off easy with care. Instructions were easy enough to follow however you will need to pay close attention to orientation detail of some parts. I would purchase another from this manufacturer.
The instructions were very easy to followI bought for a gift. And they love it.
I bought this puzzle to work on with my son. The instructions come in the form of pictures, much like the Lego kits – are easy enough to follow. The pieces come precut in several thin boards of wood. Detaching has not been a problem. However, when fitting the pieces together, several have easily broken apart rendering the piece unusable. I’ve had to superglue a few together using small pieces of paper towel to reinforce the repair. You also have to get creative with how to get some parts together as they have to be manipulated in tight spots. Overall, I wish the pieces were a little more sturdy. We are enjoying putting it together and seeing the progression toward the end product.
Instructions are clear to build it step by step.
