Thanks so very much for making this video, Leo! Some of the pictures are unclear and your detailed angles really, really helped a lot!

I built the pinball over the holidays and it took me 3 days to finish. This so much fun to build i could not getaway from it they did a great job creating it. If this is like the pinball i suspect it should be great. The workmanship in these kits are amazing.

Hallo Leo, ein tolles Stück Technik, schön gebaut und gut in Szene gesetzt. Du hast mich überzeugt, ich habe mir das Teil bestellt.

This is a fun little project my husband got me for Christmas. I'm still plugging away at it, and can't wait to see if it'll work as well as the one in this video. :)

Tank you very much! So great and beautiful ....

Thank you for your video, I just ordered this, will be my first marble run . I like the "chance" rocker on the top, so can get stochastic results.

Finally an intelligent "toy of sorts" forcing the brain to really engage! Love it!

Thank you for your video as I saw those puzzles online and my inner kid is running everywhere in me, wanting one. ; )

Wat fijn dat je ook laat zien dat er wel eens wat breekt, of dat je wat vergeet, of wat andersom plaatst. Soms denk ik dat ik de enige ben die dat overkomt.

Just saw an ad on Facebook for this and drew my curiosity. Checked Amazon for any reviews with videos and should have just started with KZfaq. Interesting concept

Super-helpful, thanks!

it was the best marble run kit that I have done, pieces fit precisely and it actually works very well. I added an electric motor and some micro switches and led lights

I have this kit waiting to put together. Might start it tonight.

I just got mine today. Thank you so much for the video. This will help alot

Sounds fun

I really like that

//well this was like a good book, once you started reading it you didn't want to put it down. It took me about five days to finish the project and breaking about five tracks, boards and whatever you want to call them, I ended up gluing them back together and also using a glue gun with hot glue to get them back together again. It worked for a few items but when I went to put them in place I had to remove some of the glue from the glue gun. I have a few areas that I have to check because the balls won't go through two areas and the balls get stuck in two places where it looks like I need to get a little more slant on the area to keep them flowing... Working on that part right now?... I am checking on the left over parts to see if I missed using them. Patience - - - - Patience..... Ron

Finished it about an hour ago. Not everything is working yet: the angle isn't quite right on a couple of the slides*, so the balls don't continue on until I jiggle it, and the collection and release isn't 'releasing'. Generally it's working better than I thought it would though, even though I can't snap the funnel cyclotron quite in place, nor the collection slide. It'll be fun to tinker with it later--that was a fun project and your videos helped a lot! You're right--so many extra pieces, and sadly a large amount of waste. I'm sure it's that way with all the projects in your vids. * the base that everything sits in (the G plate) is warped, so that may be causing some of it. I'm going to screw the whole thing down onto plywood to straighten it.

Built it all in one day as per instructions, without glue or other tools other than what was in the box. The balls wouldn’t slide smoothly through the ramps, and got stuck everywhere. The next day I bought crazy glue and glued the ramps together. I also had a problem where the ball would lose momentum and stop in the corner of the last ramp before intersecting with the other bottom ramp. My fix (which was not in the instructions) was to glue the corner of ramp rail to the surface of the ramp. This seemed to do the trick and now everything is running smoothly. The only problem that I could not find a way to fix is the release at the top. If you crank the wheels too quickly the ball will remain on the acrylic gear and fall off the machine rather than go on the ramp. It’s incredibly annoying, and the only solution is to move slowly and keep an eye on the balls as they’re moving up. Other than that it’s a fun and decent project that works 80% efficiency if you use glue and 50% if you don’t.

It is not working for me. After build everything. The ball cant get through all the track

Some one known if is possible use some kind of lubricant. The mine not run constant.

I can't get the "seasaw" at the top to flip the ball bearings both ways. Any tips? Also, in a few places the balls are stuck underneath one of the bridges.

I can’t get the small ball release paddle to release the ball. When the ball hits the paddle the ball gets stuck at the top and won’t fall. I don’t understand what I’ve done wrong.

I read the instructions very carefully and yet the marbles halt in a bend because the bend is uphill. I don't understand what mistake I made. I have to push the marbles with my finger so that they move

Has anyone tried mounting the kit to a wood base? Just wondering what type of hardware you used.

Has anyone tried to motorize this yet?

How do you press the little plastic bushings on? The tool provided is mostly useless.

The marbles fall through the holes in the middle of one of the top ramps (the one that has the things dangling down). What do I do about that? Thanks!

I just finished mine. The ball putting past the T piece at 1:47 doesnt happen for me. T Piece is plenty loose, but the ball just stops. And it can fill all the way up with the rest of the balls, and still doesnt move forward to let the balls through, or the top ones drop. Any tips?

wouldn't be too difficult to motorize!

What I meant is that some of the pictures in the instructions aren’t clear!

Mine, the marble keeps stopping at some point.

Mine just arrived today and I can't wait to dive in. These wooden puzzles are fantastic, so many spectacular projects! I came across another similar model that looks amazing too kzfaq.info/get/bejne/jaxkd92Clt_Wl5s.html Thanks for sharing your great video!
