    [MOC] Full Lego Technic locomotive - in 1:22,5 scale

    It is so elegant, so beautiful! I tried to build the exterior by technic parts but it always looks weird because the building style of technic is abstract. This model is not an ordinary technic abstract style, more like stud style. By showing wide panels and sides of liftarms, there is a similar effect of stud building. This is the only place not copied with the style of flank. Thin liftarms covered by tiles may be better.

    [MOC] Tintin Unicorn Ship

    It is the first time that I see a MOC ship with smooth hull bottom. Fantastic!
  3. I just update a GC to show these couples. I love Schwerer Gustav's bogies much more than its big gun.
  4. Hmm, Yes, you are right. I didn't design control stuff yet. It's not a big deal. The differential adder can figure out those inconsistent problems even the switch is opposite, the adder protects the system to avoid teardown.
  5. I fixed the scale and dimension then I was thinking how many functionals could put it in. Why do I need to save space if there no other interesting stuff need to equip? Besides, there is an engineering issue if only one battery pack. The center of balance is not in the middle. It could derail when turn, and also low the friction which is the key point for the train's drag force. Weight matters
  6. Thanks for the deep thinking of this model. My design philosophy is to recreate the spirit of real things. so I try my best to build the most powerful lego locomotive like its real body, this is the core motivation and must match. That is why 2 XLs needed. On top of that, let us consider engineering issues. 2 XLs have monster torques, How to make full use? Actually I wanna classify this model: Level 1: remove gear and power, it is like a static model that kids can pull by hands on the rail. Most of kids like to do this more than RC. Level 2: one group of power(1 XL+1 battery box) equipped with the clutch gear and 8x4 driven just for light-duty, That why I put an adder in the system. Clutch gear is still necessary, You know, the actual performance is determined not only by the design and mechanism but assembling is mort important. the potential lockup is not rare when inappropriate or untuned assembling, especially for the kids. Level 3: For ALOFs, we wanna release the full power, let's remove to normal 24 teeth gear, 8x8 driven. all the systems can resist high torque. Yes, your guys are right, axle damage is rare especially in a lego train. the bottleneck for the rain is always friction. For this model, it is heavy with batteries(the most tight way to increase the weight in limited space is AA battery) and 8x8 driven that maximum friction. Of course, XLs have low speed, It's also important. I linked those videos just to show the torque that the axle can tolerate. No related to the build method of Lego. Thanks again for all your guys discussion.
  7. Yes, I see. Look at this, the steel axle can resist over 1000Ncm! However, if we change axles, we have to change everything either. It will not be Lego model again. I am not a Radio Control scale model fans, at least in the forum. I prefer to follow the rules of Lego world.
  8. it was born to pull Heavy Gustav, the ultimate rail machine in human history, so, this model, will pull 1:35 Heavy Gustav which is still in my mind.
  9. Well, the 24 teeth clutch gear is like fuze wire. It has the unique ability to harmlessly slip the axle if sufficiently high torque is applied. Normally, the threshold is 2.5~5 Ncm, so if torque came from XL is over 5 Ncm, it will slip and protect all the systems. We should know a single XL motor's torque is about 14.5Ncm, Dual XLs with adder is even up to 14.5x2x80%=23.2Ncm. This is much higher than any clutch's threshold. Actually it is another topic. A single XL motor can make lego plastic axle permanently damaged. Dual XLs can twist it apart. What is the result? The clutch gear keeps the system under the 5Ncm output. When it comes to the potential, It can up to over 20Ncm, but first of all, maybe we have to change to the steel axle and other components that don't exist in Lego world.
  10. I will make a video later (maybe later than I thought, the crazy virus) while I got all the bricks that build the shell. You know, I don't wanna all your guys to see a skeleton running on the rail and,,,,,I have to switch VPN to get youtube there, where my broadband access drop from 500M to 50k~
  11. The level 1 gear followed the adder is a 24 tooth clutch gear(60c01) which can protect the system from unpredictable torque and no 8 tooth gear in the power system. adder with gear clutch by Nash Liu, from Flickr

    Train door mechanism

    How to huddle it up by motor? Your another video is already a perfect solution
  13. This is my first post that I was so confused about which theme I should post in: train? technic? scale modeling? I finally choose train tech just because it's a train after all If I made a mistake that put it in the wrong place, please forgive me. Actually I created a MOC train that is a 1:35 scale model and also with technic internal though it looks like ordinary stud-built. It's a model but not only looks look. It should be able to do something like the real one. 1, Origin It won't be happy if a man never creates something. Since my kid likes train toys very much, I start to focus on rail transportation. I found Lego's official sets are quite compromised since they need to match the mass need. The traditional scale train models are normally small and very expensive which is also hard to get in China especially one delicate like Marklin(okay, it's because of the price). We are AFOL, so I must have a scale train model, not a toy. 2, about type Targeting train is also in very straightforward logic. I am ready to build "Dora" (Heavy Gustav) as the showdown to my kid. I will tell him nothing is necessarily built on the rail after completion of this ultimate rail machine of all the time in history. Heavy Gustav cannot move by itself, I need locomotives. yes, before any creation on the rail, the locomotive is the prerequisite. That would be very clear, D311 diesel-electric locomotive was specialized built for "Dora" by Krupp. Two groups of double D311 drive "Dora" to move with each on two four-axis chassis. pic1: D311/V188 in WWII D311 WWII by Nash Liu, on Flickr 3, Scale It is a scale model that also needs to run on standard 9V track. The scale bases on the gauge of track known as L-gauge scale that is between 1 and O gauges. I choose 1:35 because there are the most resources of 1:35 Military models When TAMIYA continually push this scale. pic2: a scratch build D311 static model with 1/35 Scratch Build 1/35 D311 Model by Nash Liu, on Flickr 3, Exterior The ordinary stud brick build is always more graceful and beautiful showing than technic build. There is no weird gap and abstract design like technic exterior. However, the stud brick is not flexible to show various details and often takes up a lot of space. SOT can show as one stud, but SNOT often has to spend 2 studs to show different details. If Lego develops more special bricks and plates for combination and detail showing, the precision of the Lego model will be up to another level. Maybe Lego's official target is only toy. pic3: what this lego train model looks like(I don't have enough unicolor bricks, so I post computer rendering graph) MOC D311 Diesel Electric Locomotive 1:35 Exterior by Nash Liu,on Flickr 4, Interior Beside exterior, the model is ensouled by the functions that should be capable like its true body. D311 is the most powerful locomotive at that time, so the model also should be the most powerful train in the lego universe. pic4: super compact technic design with 4 motors that are parts of load-bearing MOC D311 Diesel Electric Locomotive 1:35 Interior by Nash Liu, on Flickr 5, Extreme Design What is an extreme design? Simply speaking, it is not a waste of one stud. Designers are very likely to MOC without limits. We can often find super complex and magnificent masterpieces on the web. But the model should have confine, at least confined by scales and functions. From the above, I list the following features. 1, Dual XL motors 2, Dual stepper motors for clutch and gearbox 3, Dual 8881 battery boxes that contain 12 AA batteries for the enormous duration 4, 2-speed gearbox 5, differential adder for XLs coupling 6, clutch between 8x8 and 8x4 driven 7, bogie integrated driven system pic5: a prototype that shows adder, XLs, steppers, and general structures Prototype PowerFunction D311 by Nash Liu, on Flickr 6, work with its couple The ultimate Gustav is still a blueprint in my brain. Many guys including me are curious that what they look like when Gustav is moving in history. I build GCs and PS with an appropriate scale. the model of Gustav is 1:72 normal design. I scale down D311 to match 1:35 by PS(Sorry, who can tell me which CAD can change design size by scale?) I CANNOT wait to build 1:35 with extreme design. Although the specification is not clear yet, one thing I can make sure and a super exciting feature is how to make this giant millipede turn on Lego standard track. It should be very magnificent.

    [MOC] GAZ 53 Soviet dumper

    Sorry, I only followed the pictures that you posted. That's true, GAZ 53 is a platform with various dumpers or other structures.
