    [TC20] 6352 Cargomaster Crane Remake

    You can move the two axles one stud apart. Then you don't need the black elongation parts. You can use 3 12T gears in a row to bring the power to the functions. Another option is to use a wave form selector. But then you need more vertical space.
  2. Even though I don't think this beats the gorgeous design of @Erik Leppen, it does not stick out and it is easy to add a turntable in the center:

    [MOC] Mammoet PTC-200-DS RIng Crane

    Fantastic build. At these sizes a whole new set of constraints appear that you have to take into account. Making it operate so smoothly is a big achievement.

    [WIP] Hennessey Venom F5

    It has been nearly a month since my last update, but a lot has happened in that time. I have modified @Anto's brilliant 8D+N+R gearbox to make it fit in my model, redesigned the rear suspension, the front suspension, the door mechanism, the monocoque and tweaked the bodywork to make the doors open/close better. So basically almost every part of the build was updated . Here are some photos of the current (practically final) state: Final functionality is: Independent suspension on all wheels Steering through steeringwheel in cockpit 8D+N+R sequential gearbox operated through removable HoG in the rear Scissor doors operated through HoG gears behind the seats Detailed V8 engine Comments, critique and questions are appreciated as always Leg godt, Jeroen

    [MOC] LTM 11200 Mobile Crane

    Wow,that is an impressive crane! I too can attest that fitting that many functions inside at this scale is very challenging and if someone would have said it can be done with 49.5 wheels and Control+ I would not have believed him. The width may be not to scale, but if you hadn't mentioned it I wouldn't have noticed, so I guess that is a good compromise you made. Driving these X-outriggers is surprisingly difficult. It is also one of the (many) functions in my crane that struggle. Keep up the good work

    MOC Amazone UX 11201 Trailer Sprayer

    Great appliance. 2 meters span with so little bending, triangles just rule the world
  7. Great model Eric. Dimensions look just right. I particularly like the use of the bottomside of the Control+ Hub as grille.

    [WIP] Orion - 1:10 racecar

    It is looking good so far. As mentioned by others there are a few friction locked solutions in your suspension that violate my own designrules, but if it works I'll be the last to complain. The monocoque is looking really sturdy. Do you also have connection points higher up for the axles to connect to the monocoque?
  9. At this point I would set the chassis aside and make a mock chassis with just 4 wheels at the right place and a central structure connecting them. Really very simple, not even steering. And then start modeling the outside. You can use all the space on the inside to make structures that can hold panels in exactly the right position and orientation. Once you have finished sculpting the bodywork you can either put it in a Lego-CAD program (including all the structures that you needed to position the panels and flexaxles). In CAD you can then remove the structures and see if you can find more simple solutions for attaching the panels that also fit to your chassis. Or you can start copying the bodywork to the chassis that you set aside and then work out the solutions for the panel positioning IRL.
  10. That is some subzero programming you have there! I know a little bit about the programming required to go from a R-theta like steering to cartesian movements, that is superimpressive to run on an EV3. Oh and the robot looks & works fantastic too. Some subtitles in the video might help though. A simple: 'learning the waypoints', 'run the sequence automatically' would help the viewer. I almost lost attention before the last fifty seconds where the magic happens.

    [MOC] Ferrari F50GT

    Thanks for letting me know. Something fishy is going on in my new website, but it seems it works again now.

    [MOC] Ferrari F50GT

    During the desing process I actually did use flexaxles, but it added a lot of gaps to the bodywork. These LEGO models are always a compromise and in this case closed bodywork won it over absolute scale accuracy. I agree about that front, it is just plain ugly on the real car . I was actually quite pleased to find this solution for the roofscoop The lights are indeed difficult to model in LEGO technic. I did think about adding edges, but these are almost immediately so thick and massive that they distract more than they offer. Again, compromises... I tinkered a bit with the springs in this model. At first it had hard springs, but my customer wanted a lower stance, so I changed them to soft springs. What is it you don't like about the roof? Would you have preferred a flat roof? thx Well, it is my job, so I do spend a lot of time building. And of course, experience does speed things up.

    [MOC] Ferrari F50GT

    Hi, Before I started on the Venom I had a couple of other projects that I was working on. Today I'd like to present one of them: A 1:10 scale replica of the Ferrari F50GT that I designed as a non-exclusive commission. It has the usual features of a 1:10 scale supercar, or at least these should be the usual features I think (are you listening LEGO?): - independent suspension on all wheels - working steering through steering wheel or removable HoG - a 4-speed sequential gearbox operated through a lever in the center column - a V12 fake engine with easy access through a removable engine cover - both doors and both clamshells can be opened As is typical for the cars from these years a black slightly upward slanted black line is part of the design. I wanted to make that brickbuilt, instead of using a sticker. There is some nifty angled framestructure behind the doors to get a sturdy solution and I am quite pleased how it turned out: The rear also features some subtle angles to keep that black line continuing, but also the exhaust pipes point ever so slightly upwards. For those interested, building instructions are available on my website. And if you have the 42125 you'll already have ~60% of the parts. Leg godt, Jeroen

    [WIP] Hennessey Venom F5

    Thanks guys, I forgot about that one. Luckily this car is designed in a modular way, so replacing the gearbox is relatively simple. I had to shrink @Anto's design a bit further to make it all fit, but I think it will work. No and yes (mini-LA's) Exactly that. Yes, the engine cover will be removable. And thanks everybody for the advice and feedback. Much appreciated!

    I made my first 8 speed sequential gearbox in my DB11 in 2016. This one is in principle the same. I try to to push myself everytime to come up with something new, but I just couldn't make it work/fit with a 7+R this time . So reverting back to a known concept feels simple to me .
