Wood Trick Galaxy Marble Run 3D Wooden Puzzles for Adults and Kids to Build - 15x12.6 - Electric Driven - Roller Coaster Wooden Model Kits for Adults and Teens to Build

I rarely write reviews but this defiantly warranted the time. This is an excellent model, but not for the faint hearted. Patients is defiantly the buzz word and lots of it. Some of the pieces can be tricky to remove from the board and care is needed not to break them. Coming from an engineering background I can appreciate the work that has gone into producing this model and I must say the Laser cutting accuracy is astonishing. Top tips: dispense with the silly little piece of sandpaper supplied and 'borrow' your wife's emery board she uses for her nails, far easier to use for the fettling jobs. For parts that have multiple location pegs, file a small chamfer on all corners of the pegs to aid location. A fair bit of force is required to locate pegs so I found a pair of long nosed jewelry pliers very useful to apply pressure in the right places. If you require glue,then something is wrong. Finally, one (and only one) small quibble, is that I found that the base board between the motor unit and the large wheel to be a little too flexible thus allowing the pinion gear to come out of mesh with the large gear under load. Sorted this by gluing (sorry) a small reinforcing strip across the base (Photo).

The tolerances of some parts are a little too tight. Many of the "mortise and tenon" style locatins are an interefrence fit and do take some persuasion. I lightly chamfered the corners of each lug to avoid the pressure needed to locate them - that's why no glue required! the holes for the balls to drop and the side barriers on the chute assemblies are extremely close tolerances to the diameter of the balls. You must ensure adequate room for the balls to run on assembly. Study the instructions and diagrams VERY carefully, at times study pages ahead to get a more positive perspective of the locations. Overall a brilliant manufactured kit and somewhat time cosuming to do it justice, which was exactly my cup of tea. Hats off to the designer, would recommend to an accomplished builder.

I was very impressed by the precision with which each part had been cut. Without laser-cutting technology this would have been almost impossible. The finished product is wonderful to watch in operation. However, some parts did not fit tightly enough together (notably the rotating dome) and had to be glued (I used Araldite Rapid), so that they do not come apart during operation. The model does take quite a bit of battery power when operating and I made a modification so that the motor can be run using a 5 volt USB supply. The grand-children love it! Walter Massey 76 yrs.

First time trying wood trick puzzle, didn't have any problems, no breakages, followed instructions closely and after a little bit of adjusting marbles run like a good un, needless to say id purchase wood tricks again as found it very therapeutic

Excellent really well made loved making it

Well, having made numerous kits in the same theme of this marble run, I have from experience learnt to ALWAYS sand ALL the edges where attached to the boards and ALWAYS put plenty of wax onto the gears and ALL the holes where there is movement. When I saw this kit, I decided this was a great challenge, and it was. The ONLY reason to give it 2 stars for " Assembly " was because it is NOT an easy kit to make. When I came to press the start button, it not only started correctly first time, but also worked completely. It is a FANTASTIC kit. Well done to all involved in producing it. Video attached. Enjoy life. Bob S

this was my 2nd model I got from ugears and found it easy to build. the only thing that I found a wee bit annoying is that the lift mechanism for the marbles is in two parts and dos not clip together it is a friction fit so had to glue it. As sometimes the marble goes all the way round instead if being sent down the run.

This was great fun to build. I was impressed by the accuracy of the cut of the pieces and providing you sand down the rough joints, seat each piece properly and fully and wax where advised - it fits together like a dream. I also like the fact that they provide a whole sheet of “spares”. Useful for the occasional accidental break - I had two but had spares for both of them. Highly recommended. Took me about 20 hours over the course of a week to build.

Me ha gustado mucho la precisión del tamaño para lograr un ensamblado muy ajustado. Producto muy divertido de montar y de utilizar una vez terminado.

My first Woodtrick puzzle. Easier to remove parts compared to other brands. Took longer than I expected, but well worth the effort. Works great after some minor tweaking. Many spare parts…if you break a part, check the spare parts sheet (it takes up more than half of sheet #9!) before you get the glue out. The wiring diagram is not complete. The manual only shows the motor white wire to the switch white wire. The rest is red to red from the switch to the battery box, and green to black from the motor to the battery box. Also, pay special attention as to when to flip the sections over before proceeding with assembly, it is not indicated as others do. And follow the arrows. The manual is large and shows where to find the parts. Past experience with these puzzles is a must. Would highly recommend. Sit back and enjoy the finished product and watch it work!

Loved this wood trick model. The best yet from this brand.

J’ai adoré monter ce puzzle, il fonctionne à merveille, je les colorier et c’est encore mieux

I just finished the Wood Trick Spiral puzzle and now I’m starting this Galaxy. These are both going to be great additions to my collection of 8 marble run puzzles. The Wood Trick puzzles are my most satisfying and rewarding to build. One thing that has made the construction easier is to organize the part cards to see their number much easier and keep the parts from falling out before needing them. You can remove the top of a box (I use a large shoe box) and cut slots out on both sides (1/2 inch wide) to set the part wood cards down into the slots. You can then easily see the card numbers without having to go through your pile of cards. Hopefully this easy to make card organizer helps others. Will update this note with a review of the finished Galaxy in a few weeks. Have fun and a lot of patience. Just completed the Galaxy and it was another one of my favorite builds. Parts fit together nicely and snug. It was definitely a fun build and extremely satisfying to see it finished. It works properly with only two items needing attention unlike most of my collection’s completed puzzles. The diverter part number 225 on page 28 would not open right or left far enough when the first marble went past it. With the diverter staying pretty much in the middle the marbles would stack up behind it and not pass to one track or the other. I lengthened the side arms on this part and the diverter works perfectly allowing the marbles to move to one or the other tracks. To lengthen the sides of this part I used the small pieces from around the large gears that fall off when they are punched out of the cards. These triangular small pieces fit the side arms of this diverter piece perfectly and are a perfect length to move the diverter from side to side far enough when the marbles pass by. I attached a picture of the diverter with the extensions glued on. The other problem was the large Ferris wheel assembly and the motor box would move up from the base allowing the gears to misalign and bind up the drive line. The pressure of the motor drive gear driving the large gear would allow both to move up out of the puzzles base. I don’t like gluing pieces to the base of my puzzles as things may need work down the road after running them for awhile. A thin strong wire around part number 4 and 5 on page 33 and the base and a wire around the motor assembly holding it to the base works well. Have plenty of patients, don’t rush the assembling, have fun with it, and you to will enjoy the satisfaction of finishing a great marble run puzzle. One of the best now in my collection.
