Note: Some commenters have asked for CAD or STL files. Unfortunately, we will not be sharing these, for two reasons: to protect intellectual property, and to prevent disappointment on the part of the requester when, inevitably, they find that simply having the CAD files does not mean that they can reproduce this system in working order. Being a complex machine, it requires thorough understanding of some of the engineering decisions in order to install, troubleshoot, and maintain, which I cannot provide. Those interested are, however, certainly encouraged to develop their own system, in which case I will gladly answer occasional technical questions.

Thanks for your kind words, appreciate it!

[@bahnvideos99]

Dieses Video ist wirklich absolute Oberklasse! 👏🏻Sowohl vom Schnitt als auch von den Aufnahmen, diesem Kanal gebührt viel mehr Reichweite für diese Qualität. Deine Videos und Bauwerke haben mich schon als Kind inspiriert mit Lego auch Seilbahnen nachzubauen da ich das einfach total cool fand, leider habe ich es nie so gut hinbekommen. Nach fast 10 Jahren haben sie mich dann wieder inspiriert mir einen 3D Drucker zuzulegen als ich das Video anfang des Jahres sah! Das war mit die beste Investition überhaupt da es den Möglichkeiten der Kreativität fast keine Grenzen setzt. Echt Respekt vor der ganzen Arbeit, sowas ist sehr aufwendig sich auszudenken, designen und dann später zusammen zu bauen. Mach weiter so und danke für die Anreize und Inspirationen etwas selbst zu erschaffen! 👍🏻👌🏻

[@TheTimmy376]

Danke vielmals für das Kompliment. Wir nehmen den Algorithmus wie sie kommt... Es ist schön zu hören, dass unsere Videos Menschen begeistern können, und dazu inspirieren, sich an dieser Hobby zu beteiligen. Wünsche dir viel Glück und Spaß beim Design und Bau deines Projektes! Wenn ich Fragen beantworten kann oder wenn du diskutieren möchtest über ein Teil deines Designs, lass es mich gerne wissen.

[@matlegofan]

Wow, your creations are better every time ! I love that you used lego gears and tire to convey the cabins in the station. Is the grip also 3D printed ? Congratulations on this new amazing project !

[@TheTimmy376]

Thank you Mat. Yes, the grip is 3D printed. Stainless steel pins retain the lever and wheels, while a spring recovered from a ballpoint pen and clipped to the proper free length provides the required grip force on the inner claw. The Lego gears and tires, although very convenient, unfortunately appear to be the design's weak point. The hubs in which the Lego axles spin wear out quite quickly, necessitating frequent cleaning and replacements. It seems they are not quite built to handle this load... Properly maintained, they work with good reliability though.

[@matlegofan]

@@TheTimmy376 wow very impressive that such small part are able to be 3D printed ! Yes that’s the problem with lego parts, they can wear quickly. I hope you will find a solution to this, but it’s still a great work, again !

[@TheTimmy376]

@@matlegofan Thanks! It's not a huge problem, really. But the solution to this will have to be in the form of a complete station redesign, where we won't use any Lego parts at all. Instead, we will use metal axles, gears, and ball bearings. And yes, very small parts can be 3D-printed, but it does require quite a bit of post-processing, such as removing support from very delicate features and drilling out holes which were printed radial to the print bed.

[@matlegofan]

This is amazing. I have been trying to build out of Lego for a while, and have yet to be successful. Do you have cad files or recommendations?

[@stefanrichter7562]

Tolle Konstruktion! Gibt es Pläne nach denen du konstruiert hast?

[@ggtransport2024]

(Project code SB22) what do you mean? Also, how did you make the cabins for the gondola? Keep up the great work 😄😄😄

[@TheTimmy376]

Thanks! The gondolas were 3D-printed using a translucent filament, 2 perimeters (0.8mm window thickness). The pillars are slightly thicker to make them appear more opaque, and are painted red, along with the floor, roof, and window frames. The detachable grip, hanger (connecting the cabin and the grip), and the ski racks are printed in opaque black, and are not painted. The hanger subassembly is screwed into mount points on the cabin, which permits a cabin to be swapped out if it becomes damaged (which has sadly happened on a few occasions). The "Eagle Express" markings on the lower front and rear windows are custom-printed adhesive stickers with transparency. The project code is basically the codename or working title of the project before it got the "Eagle Express" name. The previous year's 3S prototype was simply codenamed SB21, you get the pattern :)

[@jesseb0rn51]

Really cool model! What is the track width? 185mm like the JC or something custom?

[@TheTimmy376]

Thanks! Track width is 204 mm. It isn't based on any existing system.

[@modellseilbahnen577]

[@Martin24720]

Did you design all the parts needed for the lift and how long did you build it? Still very decent piece of work you made there.

[@TheTimmy376]

Thanks! Yes, almost every part was designed by us, and 3D-printed. The remainder are aluminum extrusions for structural purposes, and were purchased with the required diameter and length, then machined by hand. From the first sketches to the realized system took approximately 9 months.

[@lucamuller1811]

😍😍sieht fantastisch aus! was hast du für ein Seil verwendet?

[@TheTimmy376]

Das ist ein 3mm Stahlseil. Ich glaube, wir haben es damals bei seiletech.de gekauft.

[@vonrollskyway1]

From. One model ropeway builder to another, great job. Can your ropeway carry any weight? As for rope tension, what do you use?

[@TheTimmy376]

Thanks, great to see you here again! The weight-carrying capacity of this system is much lower than last year, on account of the grip which is prone to sliding on the steel rope if any weight is added. It does this because we deliberately selected the lowest reasonable spring force in order to reduce wear on the grip mechanisms and the attach/detach rails on station entry and exit. The weight of a single car is 35 grams, the most payload we've had on a single car is a 60-gram cheap action camera. Tension on the rope was set to roughly 5 kg unloaded (no cars on the line), limited by the radial load rating (70 N) for the main drive stepper motor, which bears the full tension. Best seen at 1:49 in the video, the main drive is installed on an inclined, movable carriage, sliding on 8mm rods on linear bearings. The tension can thus be changed by an electric linear motor which has about 60 mm of travel. There is no pneumatic or counterweight tensioning, it's "set and forget".

[@vonrollskyway1]

@@TheTimmy376 very nice. I'm really supprized that with no free moving tension via counterweight or hydraulic, your ropeway doesn't bounce. Simply awesome job. Come and check out what we build sometime. Great job once again

[@TheTimmy376]

You're right. I think the reason for the lack of any bouncing or pulsing is the fact that there is very low resistance in the entire system, because every sheave is on bearings, and the inertia of the rope itself, which is quite heavy. I'm familiar with your builds. They look very solid. Very impressive indeed!

[@vonrollskyway1]

@@TheTimmy376 bearings in each sheave. Very impressive. On ours we use a oil impregnated carbon fiber insert I machinened for each one. Very time consuming. I tried the bearings and over time they give out or seize up due to outdoor elements. What brand of bearings do you use for your sheaves

[@TheTimmy376]

@@vonrollskyway1 Ah, the oil impregnated insert is very clever. I can imagine it's very time consuming to manufacture indeed. Does that setup need frequent lubrication? To be honest, we simply used relatively inexpensive Chinese unbranded bearings, although they are nickel-plated (or at least, they should be). But you make a good point, weather-resistance is a concern on these. We do not know how they would hold up if this system was installed year-round like your builds. It is a common size so we could upgrade to Misumi bearings if necessary without redesign. To give you some more detail on the design, it's not only the sheaves which are on bearings: the rockers carrying the sheaves are on two bearings each, and the rockers carrying those are themselves on two bearings each, as is the main rocker arm, for a total of 22 bearings in each sheave train.

[@BradeBlake]

@thetimmy376 what scale is this? Would you consider and custom work - considering you have the components modeled, just curious.

Wie hast du die Klemme gemacht! Baue nämlich meine eigene Seilbahn gerade!

[@Seilbahn3]

Sehr coole Bahn, aber vermutlich mit extrem hohem Verschleiß bei den ganzen Plastikteilen?

[@TheTimmy376]

Danke! Etwas Wartung ist erforderlich, aber insgesamt ist der Verschleiß nicht so schlimm. Der größte Verschleiß tritt bei den Lego-Teilen im Fördersystem auf. Außerdem leidet die Klemmbacke bei sehr heißem Wetter etwas, da sie aus einem Material mit einer niedrigeren Glasübergangstemperatur besteht und regelmäßig ausgetauscht werden muss. Die Seilrollen werden durch die Fettablagerungen auf dem Stahlseil geschmiert, die aus dem Herstellungsprozess vorhanden sind, so dass sich eine Fettschicht auf den Seilrollen ablagert und sie vor übermäßigem Verschleiß schützt. Mit Ausnahme des Lego-Räderwerks sind alle bewegenden Teile gelagert. Niemals musste ein solches Lager aufgrund von Verschleiß gewechselt werden.

[@imabeapirate]

how'd you make the rope?

[@TheTimmy376]

We bought a 3mm diameter stainless steel cable, and spliced it along a length of I believe around 3 feet. We didn't have the best technique for the splice, but it worked well enough.

And the 3s? Sold?

[@TheTimmy376]

The 3S was disassembled for parts (aluminum, motors and electronics, and fasteners). All of the 3D-printed parts and custom-length aluminum extrusions are still intact though, as are all of the gondolas, so it can be reassembled without much mechanical difficulty. Selling the 3S, or this MGD system for that matter, is not something we are anticipating because of the high level of maintenance that is required, which may be difficult for someone who was not involved in the design process to do successfully.

[@ryan-faa-ptcroav]

EDIT: TheTimmy376, I have sent you an more detailed email to your email address in KZbin. Please respond there! Alright, here I go again. I am making a 4-CLD as a project, and I would like some advice. First, nice project! My previous comment, in the 3S project, got taken down, or I simply cannot find it, probably because I was asking for STLs. I found on your videos, that you don't provide or sell CAD / STL files for different personal projects. I completely agree with your decisions, for intellectual property / copyright protection. You mentioned that you can answer questions, so: 1. How did you make the grip? As seen in 0:39, it seems like there is no specific spring for the grip. How do you achieve grip strength (on the haul rope) and detachability at the same time? (If you don't mind answering, of course) 2. How do you make the sheaves go up when the grip is contacted to it, as shown in 0:38-0:40? Do you use springs of some sort? 3. Also, does the bullwheel, with enough tension, have enough traction and friction to move the haul rope? I think with normal PLA, the bullwheel will move, but the haul rope will just "sit on it" and don't move along with the bullwheel. Note: I have mechanical engineering backgrounds, some 3D printing experience, and pretty decent background in cable transportation (especially chairlifts) so you can use advanced terms related to those listed above. I hope I can get some help from you! Thank you in advance! -Ryan
