Hello! Just finished building this myself, it went well! But I notice that your model spins faster than mine. Is it because of friction, or battery , or do I need to replace the motor. Let me know, thanks! Awesome review!

Awesome review. To the kid, amazing job. To the interviewer (Dad), great questions! And happy Father's day!

I have this particular Marble run along with a couple of smaller one's which have a crank handle to turn. They turned out pretty good but I'm still a little afraid to get started on this one. You did a fantastic job young man assembling this monster. If there was one part that you would stress to pay real close attention to what part would that be? Thanks for sharing.

I completed mine and I know how much it takes to build one properly. Great job. I also think I noticed that you may have had to remove the bottom rubber band from the ramp level so the ball would not simply fly off the rail. I wonder if anyone else had this problem and do you think this is a design flaw?

Just finished my own last night. Glad I've been working up to them because it was not easy!

great video...

I just finished the Wood Trick Spiral and it was not simple. the galaxy has like 700+ parts and it is quite an accomplishment. Bravo.

Spettacolare... ciao dall'Italia

This guy sounds very familiar to Andre..

I expected the tolerances to be finer it’s a bit of a drag having to sandpaper the gear teeth.

In the UK you get the star destroyer it took me 18 hours to build it you don't get the other shops or the poster what with it

Great job, turned out awesome! I just love all these types of wooden puzzles/models. This one looks massive and challenging but that's part of the fun, thanks for sharing - very cool!

Good presentation by him ❤

Keep at it , would have loved to have had access to these modern things to learn from, may it survive warp free.

Lovely video, thanks for sharing (and making the run!) I always feel with these runs that they aren't as creative as they could be, only having three short non-interactive) routes for such a complex machine seems a waste. I yearn for one that's 'cleverer', having collections of marbles that build up to release other rarer paths and such like.

Nice review!

I noticed there is a flaw in the design. The balls will jump the track at the bottom of the 3 diving boards devices in the section you called the Zig Zag. I took off the rubber band on the bottom one so it will stay down. The ball goes too fast for it to lower the bottom one and it goes over the curved railing. I watched other videos of this and even the one from Wood Trick took off the rubber band, so the bottom board stays in the down position. I see you did that too.

I just finished one of these. I have done a lot of these wood kits made by different companies (most from UGears). It says 6 to 8 hours to build, but it took me longer than that. This is something you don't want to rush on. Besides sanding the gears, you have to put wax on them and the other moving parts. The parts will be stiff at first, but once the wax has been rubbed into the parts, they move a lot easier. I would turn each section by hand to break it in. Sometimes it helps to wiggle the supporting pieces to find the right spot where it will move easy.

I sooo love this father son interview! Great work!

Kudos. I've built a few of their models and they are not easy to put together.

I’m 41 and just discovered these. I bought an Intrism mini and had a lot of fun with it. I already bought a ROKR Marble Parkour. The problem with being 41, I can buy all of them with minimal judgement (which I probably will), I can also buy a couple extra boxes and hand them out to my geek/nerd fans as gifts! So……. Am I going down a dark path? Is this basically the equivalent of gambling program?

But lego is like $800

Good job!

Thank you. Your encouragement both in the video and the comments helped. So did seeing the finished piece.

Awesome job! Just finished building this myself and it was a blast. Only broke one piece, but luckily there are plenty of spare pieces for the most fragile ones. And to answer the question about how many pieces... there are 678. Biggest set I have worked on to date. Very fun project. Recommend to anyone that enjoys Wood Trick or Ugears models. This is my 16th one, and boy it was a dozey. If you are new to this type of model I recommend doing some of the smaller ones first so you don't waste 115 bucks.

EXCELLENT job and a great explanation. I am a modeler with over 50 years building and have just started with two of the Woodtrick train engine models. This will hopefully be my next one. I am very happy I came across your video. Keep up the good work!!!!!

Very nice job on the video,and your puzzle looks great! Does Wood Trick have an online video showing the construction of this puzzle? I'd like to have something to fall back on incaae I have a question. Thanks in advance Ralph

Great Job , I bought this and I'm a little intimadated by the amount of pieces. Hope mine runs as smooth as yours does when its done.

@Andrey Smirnov perhaps you might not want to post on TFL videos with your personal account? And you might want to change your privacy settings on facebook, unless you don't mind everyone looking at you, your wife and daughter. No disrespect, I've just seen plenty of other youtube stars get hounded by crazies. Thanks for the funny video & keep up the good work!
