[MOC] Mining Dump Truck - Lego Technic 42114 Model B
eric trax posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Building B-models between major projects has become quite normal for me. Such a break and playing only with Technic bricks is a very good way to reset my mind 😊 This time it was the 42114 set and the Mining Dump Truck was created as an alternative model, for the excavator from the 42100 set. The plan to build this vehicle from the 42114 set appeared a few months ago. I put it off for later, because I thought I wouldn't have enough panels to build a nice dump box. Over the weekend, I sat down with bricks and in a few hours the first version of the tipper was created. I liked it so much that the final version differs from the prototype only with minor changes. The biggest difficulty in building this model was its size of frame. When planning, I insisted that the model must use the original app, because that could be easily configured and played with it immediately. The machine has double wheels on the rear axle, so the frame basically contains the engines, gearbox, and a rear axle. In addition, the set has only long actuators so placing them in the dumper was also not easy. At the end, everything was packed into a pretty nice model, which uses over 78% of the set elements. The tipper was supposed to look good with the R9800 excavator from the 42100 set. So I scaled the Liebherr T282 to 1:42 scale and built the model on it. The appearance of the dump truck is a combination of the previously mentioned Liebherr and CAT 793F. It is not an exact copy, but there are similarities.

Liebherr PR776 Dozer - Lego Technic 42100 alternate model
eric trax posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The idea for the B model in the form of the Liebherr PR776 appeared in December 2019. Unfortunately, I had no experience building alternative models, so first I assembled a simpler model - skid skidder based on Bobcat T870. Having already some experience and, what is important, knowing what I can afford during the build, especially the list of parts, I made it. I tried to make all the functions and as much as possible to make the original look like this The tactic I chose when designing was to check whether the new engines and hubs would fit in the 1:18 scale model (scale to the wheels). In fact, when I put the first hub between the tracks and the drive motors, I ran out of space in the chassis. Another problem was the new, long actuators. While they are great for lifting the blade, they are too long for the ripper. In the original, these actuators are very short. To keep the dimensions of the ripper I had to build them much more into the center of the model. This added another space problems and the need to place one of the engines at the bottom of the frame. I really wanted the model to resemble the original as much as possible, so I started building with modeling the hood. Then I took care of the blade, which consumed almost all DBG system bricks. However, the basic curvature was pretty nice. Its appearance gives a lot of visual effect. The problem was the shape of the cabin. I don't know who designed the original, but there is a suspicion that he was drunk. Fortunately, it was possible to create a quite realistic cabin and interior. It is masochism to use the Control + system on models of this scale. How to build in two large hubs so that you can replace the batteries from the bottom and turn them on from the top? The first hub is located under the hood between the tracks. From the bottom we have access to the battery and we activate it with a clever switch in - the left platform. The second hub is located directly under the cabin. This can be easily folded back to gives access to the control hub and turn it on using a switch in the cabin The model does not have a realistic suspension. I resigned from it because the model weighs over 3 kilograms. I really wanted it to be stable and the tracks did not make such terrible sounds as the model A while driving. There are, however, four tilt carts that make it easier to climb over obstacles. Some technical data: Length: 46 cm, Width: 25 cm, Height: 23 cm, Weight: 3.04 kg Drive and steering – 2x XLarge C+ motor Ripper – lift (Large C+ motor) tilt (Large C+ motor) Blade – lift (XL C+ motor), tilt (Large C+ motor) I wanted the application configuration to be as simple as possible, so I also created a custom profile in the buwizz application which greatly simplifies the configuration of the model control. I also made a layout to make the control panel pleasing to the eye.

42100 test stage 1
Sammerz posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello Just wanted to confirm the rotation of the black wheel/cog during the stage 1 test for 42100. The app makes it look like it should turn a full 180 degrees and then turn back... but when I test it is doing about a quarter turn (around 90 degrees) then turns back Could this be wrong or I am being over cautious... Many Thanks Sam -
[MOC] Skid Steer Loader - Lego Technic 42100 Model B
eric trax posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi. Guys! :) The high pace in building agricultural models I imposed myself last year meant that I had to take a break. I need something completely different and new challenges. Then I decided that it would be interesting to build an alternative model for the official set. The limited amount of bricks always boosts creativity. The 42100 set doesn't have a B model at the moment. When I saw model of Bobcat loader build by my friend Makkes', I thought it might be a pretty interesting idea for an alternative model. However, I didn't want to build a typical skid steer loader. Looking through this type of machine, I found the Bobcat T870. It is interesting because it has additional links and support arms. For what? Well, to get the vertical lift path. The whole system eliminates the bucket moving back effect and this makes loading onto trucks much easier. I built a loader in just over two weeks. Scaled to the wheels gave a 1:9 result. From the first pin, I planned that the model would be built modularly. It caused me a bit of problems but I learned a lot and the whole construction contains 14 modules. I started by building caterpillars and I am very proud of them. Technic links are very well stretched much better than in model A. The model is not complicated but its construction gives a lot of fun for example connecting the caterpillars with the frame and then the drive. When I ran out of one cardan, I decided to assemble it from the available elements. I wouldn't be myself if I didn't take care of visual issues. I knew at the planning stage that I wanted to finish the cabin with pneumatic hoses as a cage. I added many details such as oil tank, distributor, radiator, muffler. When we talk about visual details, operator's seat is my favorite part. I am aware that the model does not use the full potential of the set. Only a Control HUB and three engines and some parts are left for use. I treat this model as a warm-up before the next one Marek, as usual, create building instructions for the model and of course he did a perfect job. The original application is not suitable for control this model, so I decided I would create another instruction for the BuWizz application so that everyone could easily configure it. Model dimensions: Length 42cm, Width 23cm, Height 26cm, Weight 2480 gram Drive 2x XL, arms lifting XL, tilting bucket L motor. The building instructions are available at: https://sellfy.com/p/dwatsg/ https://rebrickable.com/mocs/MOC-37222/M_longer/42100-skid-steer-loader/ Photos and video below. This is my first alternative model so I am interested in your opinions. -

Hi everyone, I’m started a heavy machinery channel on YouTube. I have taken advantage of this by doing a review of the technic 42100 Liebheer. It’s different to say the Sariel reviews. Side note, I’m not some hungry salesman. I’ve been in the Lego community a while. While my collection isn’t as impressive as Blackbirds. I’d be interested in doing more if this gets enough attention. Check it out and please let me know what you think. https://youtu.be/N9yB-ITD2QY -
[ Movie ] "Excavengers" battle (PF vs Control+)
cyberdyne systems posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Soon after I've got my 42100, I decided to use it for making something epic and funny. So, after a month of work I've made this "movie" which tells a story about the last battle between old and new. Don't take it too serious, just have fun! P.S. Moral of the story is that the winner hasn't won at all. Cos' all the fallen gained an ability to be revived into different models and live forever, but the winner will stay useless and untouched. :) -
[MOC] Lego 42100 Mini-Replica
cyberdyne systems posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Good (random time) everyone! I was fascinated by the 42100. So, as I still haven't got one, I've decided to make my own version, but a bit smaller... I came up with an idea of an extra small excavator with all possible functions on board. No RC this time, of course. Only manual controlling. The bucket was a hard thing to do. But this quarter-cylindrical piece and a rope served me really well. I tried to make it as close to the real set, as possible. All the pipes, railings and barrels were recreated in my replica. The mechanisms inside the haul are both simple to understand and hard to invent: First boom section is raised via small linear actuator placed inside superstructure The same LA lifts the second section Worm gear to turn the levers system which tilts the bucket The bucket can be opened by pulling the rope Big turntable supports the superstructure. I don't really know what else to say/write. So the video is at your service. This video is a bit humorous. I hope, you would like it. Thanks for watching! -
More opinion about custom 3D printed Technic parts
896gerard posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Dear readers, For a new project that started a while back (about a year ago), I was investigating a certain track configuration for a tracked vehicle. It pointed out that I needed a lot of ground clearance from the track wheel, but the track wheel could not be two studs wide: the tracked vehicle is only 15 studs wide and a lots of gears, motors and linkages need to be in between. As you can see, the standard wheel above is two studs wide due to a ring of 1/2 a stud that supports the track. This ring is not always necessary. In fact, the tracks barely even touch this ring under normal driving. A lot of you will recognize the difficulty with this wheel: it protrudes half a stud to both sides. In many designs, the number of horizontal studs is uneven: an M motor, XL motor, frames, differential, everything has an uneven width when measured in studs. This enables a symmetrical design as Lego Technic has no beams with even lengths (only 3, 5, 7, 9 ..). That's why many Technic designs of this day are an uneven number of studs wide. This is in contrary to the olden days, where all Technic components and widths were even. Check for example the old style liftarms, differential, frames, motors and even battery boxes. With this theory lesson over, it is easy to see why this track sprocket introduces a problem: when the wheel is mounted in the uneven Technic system (to get a nice symmetrical design with uneven Technic beams), the wheel size is even! So the wheel can not be connected to a liftarm at the place where the axle connects to the wheel. There needs to be a distance of 1 stud to any supporting liftarm. This is mostly done with a bush or a 3L thick liftarm. This also means that to mount this sprocket very strongly, the minimum width of the structure (when fit in an uneven system) is 5 studs. Then I started thinking: how nice would it be if there would be NO distance to any supporting liftarm? In that case, the sprocket has to be only 1 stud thick and the supporting structure is only 3 studs wide. Also, the support ring has to go. This is an enormous space saver when the maximum width of your vehicle is 15 studs.. I decided to draw the part in Solidworks and print it with my own 3D printer. Out of curiosity, I checked GrabCad to check whether someone got the same idea too. To my amazement, somebody had already tried this part, with the internals to be the 40 teeth gear. This is done with a reason. A standard 3D printer is generally very bad at printing axle holes. If you draw the outline of a standard Lego Technic part (that has a nice axle hole) into your 3D printed part, the part will be connected firmly inside the model(nice) while the axle is inserted into a Technic part, so no troubles with cracking plastic will occur. In short, I printed that part. It didn't work. (See image below). It turned out that every 3D printer is a little different. A tiny offset can cause a diameter difference, which then will cause friction, because the track doesn't fit around. The wheel needs to be perfect to make the solution work. That's why I decided to design my own custom sprocket wheel from scratch. This was my first 'from scratch' attempt. As you can see, the pin and axle holes do not have great quality. A revised 3D design is in the image below. As you can see, there is a large hole in the middle. This hole fits two 4185 pulley wheels (shown right) very tight. This means the vehicle is connected to a nice and round axle hole, while the 3D printed part is also fit very well to the vehicle. The sprocket diameter is not arbitrary as the number of 'lobes' is fixed: there are no half lobes, otherwise the wheel won't work.. That means that for the same tracks, a limited number of wheel diameters exist. As you can see, there is a slight ring in the 1 stud wide sprocket wheel, not all track support is gone. The 3D printed results: I was really happy with the quality of this wheel, the drawbacks from 3D printing don't show up and the wheel is very strong and straight. In the image below, is is visible that the tracks fit very smoothly around without additional friction. It is also visible that the wheel is just as wide as two pulley wheels, so one stud. I was so amazed when the 42095 set was launched. There was my not-published-about part, exactly the same size, in a real Technic model! And now there will be 4 DBG ones in the 42100 Liebherr, which will drop the price. There is one 'slight' drawback though. My 3D printed wheel is only one stud wide, needing only a frame of 3 studs wide to support it. The new 42100 sprocket wheel has the 1/2 stud ring protruding out of it on both sides, taking the drawback of the old wheel onto the new wheel. That's a pity. It could have been so nice. Then comes the question: why would you 3D print parts? That's cheating. And I agree. It is cheating. I never do this in my models. You are allowed to check my YouTube. I even built of a 3D printed way of getting three axles through a Lego Technic turntable but never used the solution as I do like pure models. Then, why am I doing it now? Because currently, I'm using Lego Technic as a strong platform for a scale model that requires 100% of the quality of Lego Technic, but cannot do without adding custom parts. Even the most skilled builder cannot work his way round sprocket wheels that don't exist. That's why I see it as an engineering project, and from that prospect, creating your own parts (when all else fails or doesn't exist!!) does not show lack of skill but broadness of view.. Surprisingly, some other minds thought alike and brought a Lego Technic wheel of the same size on the market. Too bad.. Let's start building and stay thinking! -
42100 QA Issues
Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Here are the issues I found during build of my 42100 set: 1. Damaged motor - I had a simillar injury on one of the C+ hubs in the 42099: 2. Actuator's input shaft color is Dark red instead of Orange. Also one actuator seems to have corrosion, while the other has a very rough surface finish: 3. Instructions have a few issues too. The 2L axle here can interfere with the 12 tooth gears if not inserted fully. I'd use a normal cross-pin here: 4. This assembly is almost impossible to take apart without damaging bricks: 5. You can't test the model in third phase. App won't connect to the hubs, because all motors are not yet wired to the hub. I'm thinking contacting lego costumer service regarding actuators, they seem to be a poorer quality than normal ones and they also feel like they are totally unlubricated. What is your opinion on the issues above? -

[MOC] Lego Liebherr R 9800
Tomas TECHNIC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I really like the Liebherr R9800 so I decided to build it myself. My version has got six functions (all powered by PF elements, controled by three IR receivers) Drive - one L motor for each track Turning superstructure - M motor Arm - XL motor, M motor, M motor It is not as big as official Lego Liebherr but functions (I think ) works really good.
