Kuličková dráha se spirálovým zdvihem

Perfect function, I enjoy playing with it daily....

The spiral hoist is a great challenge both for brain and fingers I can reccomend this type of puzzle building as excellent. Aged 88 common sense says stop, but the challenge to brain and shaky fingers is not to be igfnored, I will be back for more challenge 88 or no 88 Graeme

Straight forward to assemble. Assembly instructions are excellent.
Overall, a great product.

I absolutely love the Ugears marble runs; they're a huge step up from other brands. The best part is that they're completely manual and made of wood—no plastics or electronics, which, for me, really takes away the charm of these devices. As always, I'm amazed by some of their mechanisms, like the spiral lift or the "start race". It's truly a three-marble race! I can't wait to build another model to connect with this one. Which of the other three models would you recommend me? The only downside is the manual crank, which is a bit stiff and doesn't turn smoothly, may be should have more gears previously, Thanks, Ugears, great job! 😎👌

I've assembled a lot of Ugears models. This turned out a lot better than I would have thought, considering how complex it is. It worked on the first try. Take your time, sand and lubricate everything, use spray Dry-Lube, and its' great! Thanks for a great model!

This is a fantastic kit, with several gimmicks and a very clever track design. I used paraffin oil to lubricate it, which worked very well and it ran very smoothly. But there are some areas for improvement. I hope that the part near the lifting end of part 116 can be tasted a little better, and the E8 area can add a fence outside. I don't know why the ball sometimes flies out from there. And I hope to add electric drive, which will improve the viewing experience

I loved building this kit, it was by far one of the more enjoyable ones I have done, the movement and design is fantastic!

There are however a couple of improvements I would suggest...

1. Either pieces 37 need to be a bit longer or pieces 50 need to be a bit shorter, the balls keep getting trapped between them. I have removed them and taken the edges back a bit with some sandpaper and it runs better now.

2. The torque from the handle is too much for the tower to resist, this would be improved if piece 25 could somehow be connected to the base at another point to help resist the torque.

3. There are more moving parts in this model than I have encountered before and the wax is not always sufficient to lubricate the surfaces, I have taken some pieces apart and used a light furniture wax to improve them movement.

Hopefully this helps!
