Feinmechanik in Perfektion – Wunderlandians #16


My “Wilde Maus” (wild mouse), as we would say… As you know, we’re currently building a fair, a big project with more than 40 rides. There is so much to do like technology, movements, lights… It’s going to be awesome! This is my part, I’m building Ikarus. It’s a ride moving up and down and spinnning and it has single gondolas which also rotate. The biggest challenge will be providing the single gondolas with electricity. So this is my part, this is my base plate and now we’ll start. I used to work as a medical engineer, it was a nice job. But at some point, I had enough of it and wanted to do something different. I wanted more freedom and self-realization, something the Wunderland offers a good platform for. We ordered this model building set from Scholz. I’ve already taken a look at it and gave it to the model building department, they can start putting some of its parts together. In the meantime, I took a look at the original pictures. I then decided to place the enginge on the inside. At the original, a cable pull is used. But I consider a different drive to be longer-lasting. The idea is having a square middle piece, with a spindle inside and its motor below. This will make the entire waggon move up and down. This was my first try of preparing a square-cut. It wasn’t successful, the material loses its shape as soon as I start cutting. The split in the middle changes and there isn’t enough space for the carrier. My current idea is using a u-profile. I want to mill it until it’s a square with an edge length of 15 or something like that. I’ll leave out a little split in the middle to use it for the waggon’s carrier. This is the u-profile I’ve already milled. It used to be 15×15, I’ve just milled down the sides. I’ll place a spindle inside which is driven by a motor below. This will be my carrier. How do I approach such a project? I first take a look at the model building kit, you can get these from various companies. I then decide which parts of it I can use, usually only the cover parts, the technology has to be done by me. Otherwise, it wouldn’t survive operating times of 16 hours a day. Then I think of how to do the movements by using gears, belts, chains or spindles, there are plenty of options. The rest usually happens step by step. The column is ready. This is the base plate we’re now milling a square into. The column will be placed in the plate and then I’ll think of how to add the motor. After having done that, we’ll have realized the up and down movement. Everyone basically takes the projects he likes to do and thinks he is able to do. In my case, I chose the free fall rides, the free fall tower and Ikarus. I thought I was suited for these projects because of my way of working and my technical knowledge. That’s why I chose these projects. The column for Ikarus is ready, the base plate is prepared and the motor holder is milled. I will now put it all together, so you can see the progress. It already moves up and down, the next step is building a waggon and providing it with electricity. I thought of using spring steel wire. My current idea is attaching it next to the column. The waggon will move up and down on the outside. I just need to figure out how to transfer the electricity from the spring steel wire to the waggon. It will work out somehow, I’ll think about it when it’s time. Here I have a round piece of plastic, but it doesn’t have the right diameter yet. This will be the main part moving up and down. I have to make it smaller and square-cut the inside. In addition to that, I have to think of a way of attaching the two carriers. I prepared the waggon and will now start doing the square-cut. The column is four-sided and this is the part moving up and down. How did we develop the ideas for the fair? In the beginning, we sat together and thought of ideas, no matter if they were realistic or not. We sat together and imagined a fair that would be more spectacular than a simple model. I had the idea of building a small cotton candy bar. The visitors could have taken a tooth pick and make their own cotton candy. But it was not possible, having food in the exhibition is too difficult. We’ll place the finished part on the column. Now we’re having up and down movements. Now I have to think of how to let it turn, most likely with a gear wheel motor. This is where we place the spring steel. My idea is using brass hulls, maybe with a copper netting inside. They could run on the spring steel and would be my current collector. That’s the plan. Last time, we achieved that this part moved up and down. In the meantime, I made some progress. Michel milled such a cross for me. It’s the same size as the original, but made of aluminium, not of plastic. It’s already painted, that will make it easier for us later. This is where I will attach the copper rings and a holder, it will be my current collector. How about the movement of the cross? Thomas printed this for me and it works well, it will be attached down here. This is where the motor will be placed, a gear ring is still missing, otherwise it would move. Where would I place myself if I’d be a figure of 2cm? Most likely at the Elbphilharmonie. It’s such an impressive building that took lots of time and technology. It was such a spontaneous project, from monday to friday, it was a little stressful in the end. Eternalizing yourself there must be cool. Most special about our work is the freedom we have. We can develop and build push-buttons and add our own ideas. We can work on our own, but also ask our colleagues for help whenever we need it. Then we talk about it and build it together, that usually works well. As you could see, I put the pieces together. I will now attach the contact spring on the side to transmit the electricity. Then it should work. I still have to move it to the top, that’s what I wanted to use the spring steel for. Therefore, I want to use brass hulls the spring steel can move through. This is where I want to get the electricity from. A while ago, I tried letting spring steel wire run through brass hulls to provide electricity. But it didn’t work, there were too many contact failures. That’s why I want to add a copper netting. I want to achieve better contact. Which push-button needs the most maintenance? My “Wilde Maus” (wild mouse), as we would say, the cable car whose cable constantly gets damaged. It happens all the time. Sometimes it works for four weeks, sometimes just for three days. But I didn’t have time yet to work on a more sustainable solution. This will be installed next. It looks impressive with all these thin wires. The next step is adding the spring steel wire. Now there’s a connection between the spring steel and the collector. I still need to add cables to provide the rings with electricity. From there, I will go to the motors on the outside. I will need two or four additional cables for the lighting. I made it. Let’s put it on the column. Everything is installed, now I will add some provisional cables. Next step will be trying it out on its original place in the exhibition. Do I sometimes listen to the people trying the push-buttons I built? When I walk by, it is indeed interesting to see how many people there are and how their reactions look like. You are happy if it works and the visitors like it. Ikarus is now in the exhibition. With provisional cables. I will quickly put it together and then we can start. These things are supposed to move aswell. But they don’t. They are now spinning a little too quickly. But at least they are moving. The problem was that my current collectors for the up and down movement crossed and caused a short circuit. Let’s see if the whole waggon also moves up That looks good. The current collectors work well. These are the conducting wires I used spring steel for. It runs through a hull with a copper netting inside. Over a pressure contact, the spring steel wire transmits the electrictiy to the outer copper rings. And from there, it goes to the motors. Ikarus will now move back to my work place. I will line it and change the provisional cables to a final version. The lining will hide this construction. Ikarus also needs some lighting. There is much to do and we need to hurry if we want to open the fair by the end of the year to present you something extraordinary. We hope that you liked this little insight in one of our projects. See you!

  1. Ich würde euch bitten, die Skipisten in Österreich durch fahrende Skifahrer zu ersetzen. Das würde mich sehr freuen und den Themenbereich auffrischen.

  2. Super Einblick und Respekt vor der Ideenvielfalt und dem Engagement um solch komplizierte Vorhaben umzusetzen.

    Hier kann man deutlich sehen welch ein Aufwand nötig ist um trotz der Komplexität en Miniatur einen realistischen Klon herzustellen.

    Man versinke in Demut! 👍👍👍👍

    Dankeschön für das Video.

    👍👍👍🇺🇸🚐🇺🇸🌞😎

  3. Cool! Haben diese Klebestreifen mit Domino-Muster auf der Anlage eventuell was mit der Shaper Origin zu tun? 😀

  4. Ich liebe das Wunderland. ich bin mit meinem Sohn extra nach Hamburg gefahren um das Wunderland zu besuchen. Ich finde Italien ist der WAHNSINN. von der Darstellung meiner Heimat War ich etwas enttäuscht ( Österreich )

  5. Immer wieder schön zu sehen wie ihr trotz der gewaltigen Größe so viel Zeit und Liebe in die Details steckt. Sehr gerne mehr davon! 🙂 Lieben Gruß aus Bulgarien.

  6. Die Kirmes wird der Hammer 🔨.Die Realisierung des Fahrgeschäfts ist turbogeil.🤩👏👌
    Klasse Arbeit.👍
    🐉Gruß powerandy 2020

  7. Der Wahnsinn schlecht hin. Da kann man sich glücklich schätzen, wenn Leute mit solchen Ideen und Umsetzungsgeist an das Werk gehen und es funktioniert! Chapeau! 👍👍👍

  8. Servus MiWuLand. Sehr interessant wie so ein Model in der Planung anfängt und dann zum fertigen Modell wird. Auch genial, wie man zu diesem Beruf im MoBaLand kommt, also was er davor gemacht hat. Echt genial sowas mal zu sehen. LG Tino

  9. Super Clip und tolle Lösungen die ihr euch einfallen lasst, zwischen Modell getreuer Nachbildung und Funktionalität, die dem Dauerbetrieb ja stand halten soll.
    Das Fahrbild vom Ikarus finde ich ohnehin sehr schön. Schade, dass man ihn auf der Reise nicht mehr sieht.
