    Actuallly, I could've bought a vintage real truck for what this MOC has costed me in total, but well... this one is more convenient to store away than a real one at least Noticed that I forgot to answer your question about the lights. The front headlights are those vintage white 1x2 bricks with built-in bulbs. The poppys, Michelin men, spotlights in cab and taillights are all the PF LED lights.

    Hi Lego friends! A short video of my Lego truck, a Volvo F12 Globetrotter log truck. I've been building it over the last couple of years, when money and energy has been present. It's close to 1:10 in scale and weight is 7,1 kilos. It's driven by two buggy motors and the steering is provided by one XL motor. Until the other day it also had a gearbox, but when making the video that gearbox failed utterly so I removed the whole thing and connected the motors straight to the axles for now. There's some more information in the video description if you are interested in the build. It's quite uncertain if I will work more on this truck or not, maybe it will be scrapped, but at least I wanted to share this short video of it here. Hope you enjoy!

    I'd love to try one in real life... but that will probably never happen. There are differentials in the trucks axles, but no ability to lock them. So if one wheel on each axle would start to slip, I'm stuck. But the truck isn't built for terrain unlike the forwarder, it's built because I've always wanted a truck and can't afford a real one

    Some pics then... About the Forwarder, search on my Youtube channel for "Forwarder" and you will find some videos of it. (Why on earth does my quote end up in my picture post???)

    Hi and thanks for the comment! For some reason I don't suceed in creating an account at Brickshelf (when I hit create account, "The webpage couldn't be found", but maybe later on if I get it to work.

    Hi Is there any way to retract the LA in Lego Digital Designer? Or is it only useable fully extended? Thanks in advance

    Hi all, A little presentation of my LEGO Forwarder named XXL for obvious reasons :) It has been a project in my spare time for some years now and still not finished (probably never will be...) Most basic facts: Weight: 6,7 kilograms Dimensions: 95xx36x50 studs Drive: 8 XL motors + hub reduction Steering: Forced by controlling front left with rear right and the other way around (because of the weight in combination with the huge friction from the wheels) Wheels: From 8466 (4x4 Offroader) Some vids from Youtube: Feel free to comment or ask questions, I´ll try to answer them :)

    My last video. Can anyone top my load? ?

    Well, it ofcourse depends on how long tracs you need to get the right fit for your tyres. And if your tyres are not as wide as the powerpullers, you'd need to build with other parts than me. But you can see in the videos how they are built up, one trac consists of 455 pieces right now.

    More mud is not an option. When inspecting the mess after that movie, I noticed that in the bottom of the XL motors there is a hole right into the electronics... I wasn't aware of that when driving into the mud, so it was pure luck that the motors survived. I can't seal of that hole without reducing ground clearence, which has high priority. Also, the wet mud almost destroyed my $250 tracs, it had penetrated into them in every possible way, they were extremly stiff when I got home. More suggestions?

    Thanks! It acyually took me some YEARS to come up with a design that fitted the powerpuller tyres and was strong enough for the task... However, a new video today! There will be another one in the next few days, however not this dramatic, but then my wallet needs to rest a while before next video can take place.

    Yet Another video shot today, enjoy!

    Well, I like to try limits ? and when I build something I want it to be as close to perfect as possible, so I have to torture it to see if I have done a good job ? now I know that the turntables are the dealbreakers load-wise, and I can't change them, they are what they are. When they separated in the video the total weight was almost 13 kilos, and going uphill most of the load was at rear wheels. Add to those conditions that the tracs have quite high tension, so there's great force on the turntables from the tracs alone. A little rough terrain on that and they separate, sadly ? So if the machine gets going again, I'll have to come up with a movie theme that doesn't involve any load ? The tracs are now in the bathtub, I haven't dared to have a look att the wheels and hub reductions yet, but probably I will have to disassemble it all once again. I assume many parts are toast ?

    Some new videoclips, hope you enjoy ?
  15. morson1
    Any suggestions of theme for new movie(s)? Improving the creature on various points right now, but soon it will be ready for new challenges. But I have no great ideas... ?

    Okey, some help would be appreciated. Yesterday I tested the Forwarder with some serious load, and the rear motors cuts off very easy. Where is likely my problem? The setup for each pair of wheels is: 1 battery box ----> 1 V2 receiver ----> 2 XL motors (connected together at one of the receivers outputs). Which is the weakest link with this type of setup, the battery box or the receiver? Would it likely help me to run 1 battery box and 1 V2 on every XL motor separate (at least at the 4 rear Wheels)? I need more POWER The problems starts @3:00 in this video, the rear wheels won´t move, and there is no way the front wheels can move can move that piece anywhere by themself, especially with rear wheels locked...

    Another vid (I thought I accidentaly deleted this video file but found it yesterday, shot at same day as other two videos). Enjoy!

    ...and another one

    New vid from today, enjoy!

    Yes it's planetary, so 1:4 then ?

    My main goal was to build a powerfull machine drive-wise, and that it should be able to load a log but not much more than that. As the boom is around 50 cm long and quite thin to not look bulky, you can imagine the forces on the parts if I'd try to lift something "heavy". But actually I've never tested it's full capacity. Now the machine has been stuffed away several months with empty batteries, I'll try to get my hands on some new ones and make some more vids. I was quite happy when I came up with the double LA trick. I'm sure many others also done that, but I didn't find the idea somewhere, it just suddenly popped in my head. ? But it took alot of trial and error before I got it to work and stay together. About the cab, as you've already pointed out, it's full of PF stuff, and they already work really bad in daylight so they need all line of sight they can get... So right now there will be no more details in the cab. I've had plans on lights however, but that is just plans this far. Ehm, math is not my ballpark, but the XL motor is mounted straight into a large turntable (which forms the rim), motor has 8 tooth gear, you do the math ?

    About connecting two battery boxes parallell: I´m building a vehicle with 5292 motor, and it stalls way to early. Been reading around whole day, but not sure anyway, so I ask for safety reasons... Is it possible and safe to connect two battery boxes in parallell to get more current? If so, can I power one receiver (V2) with those two boxes, or should I go for two separate "power units" each containing one box and one receiver (mating up at the motor)?

    Hi, Trying to build a truck here, and have a question about Ackermann steering geometry. My truck will have two driven rear axles, fixed axles, non of them steerable. If you look at the attached picture, which alternative is the correct one? Should I line up my steering according to the blue lines, pointing at the center of the first rear axle? Or should I aim for the red lines, which points at center between axles? Or are both alternatives wrong, and in that case, what is the correct solution? Thanks!
  24. morson1
    My main interest from the beginning was really if tyre scrubs occur on both axles on a real truck, or if real truck manufacturers goes for the blue line in my drawing and put all the scrubbing in the rear of the two axles, meaning that the truck acctually turns around the first of the rear axles. The note about Power Pullers was about my forwarder. On the truck I will use ordinary truck wheels.
  25. morson1
    The Forwarder: PowerPuller wheels, 8 wheel drive, one XL on each wheel, straight into hub reduction. Forced steering. Four LA:s for lifting boom, driven together by one XL. Claw rotates with micro motor, claw open/close with pneumatics. That's about it :)
