  1. Hi all, after a quite long absence from the forum, I'd lilke to show you this small MOC I just prepared. It should have been a model for the Octrainber, but since I've no time to prepare the whole diorama, I'll show you only the little railcar. The Egger-Bahn is a model line created in the 60s, based mainly on fictional freelance rolling stock (even if some models were inspired by real prototypes). These models were in 1:87 scale, running on H0e track - therefore simulating a narrow gauge system. One of the main models was the articulated steam railcar you can see in this picture taken from internet. The lillte railcar is articulated and composed by a steam motor and an half-passenger wagon. It is a very nice model and I've always liked it! Since I'm working a lot on big scales, I wanted to do something different, so I got back to 6-wide on 4-wide track: It's super-deformed as my other small locomotives I made , and it's based on the 9V red MicroMotor. It can run on black Lego narrow-gauge track and on LEMAX Christmas Train track - which is perfect for small Lego models (and features straights and larger curves). Here below you can see the different components, like the MicroMotor, the rear bogie, and body parts (motor and trailer). And here's a detail of the motor and passenger trailer. As you can see, the 9v MicroMotor is mounted upside-down, and moves the rear wheels of the steam motor. The power comes from a 9v battery box, but I succeded to run the Micromotor on small 12v batteries. Some home made electronics may save space! The batteries should be placed near the trailer link, therefore their weight - insisting on the only driven axle - can improve traction. I hope you like it! Ciao! Davide
  2. In honor of Good Friday during the Coronavirus pandemic. We need look no further for hope than the atonement of Christ. This is my first attempt at a fully articulated figure ... and also my first Bricklink Studio render. The body is colored with a combination of dark orange and medium nougat. All 5 wounds are represented with wands used to show the blood dripping. The use of angled curve slopes and tiles hints at musculature. Claws, minifig hands and a round plate with handle are used to represent the delicate details in the hands, feet and face. The King's crown of thorns is made from a barbed wire element.

  4. Hey guys, here's a rather simple project I recently started. I wanted to build something that's highly playable and not too complex, so I decided to do a tracked vehicle of some sort. However, this one will be unique in that steering is not done by tank drive, or by traditional steering. It's by an articulation joint like a front loader. This model will have all-track drive, articulated steering, and a pneumatically tipped bed. The bed will be on the rear module, which will contain no motors. All motorization is done on the front module and the only things passing through the articulation joint/turntable are the drive axle and pneumatic hoses. Propulsion is done by a single L motor above the front differential, steering is done by a M motor that controls 2 linkages going in opposite directions with worm gears, and the pneumatics are controlled by a M motor that simultaneously drives a 6L pump and Sariel's autovalve. The mechanical elements do take up plenty of room in the front module, but once the bodywork is in place most of it should be concealed. My main purpose in building this MOC is to find an opportunity to really use dark azure Technic pieces. My Grapple Truck I6 and my current WIP Red Beryl X were both started with the intent of using dark azure pieces, but both times I was faced with a limited collection of them. I've recently ordered some extra dark azure pieces off Bricklink, and considering a cab on a model this size shouldn't really use that much pieces I think this finally be my first dark azure MOC. If you guys have any suggestions for me, please let me know. Photos:
  5. Ever since I've started to use beams-built tracks, I have been suggested to use rubber axle joiners instead repeatedly. These are a bit expensive when you need a few hundred of them, but I've finally hit a clearance sale, and well, here's an experimental vehicle. It has a number of problems, but now at least I know what not to do when using rubber tracks: Reading & photos:
  6. Hi, this is my C Model for the 42043 - MB Arocs, It's an articulated tractor with a tipping trailer! Tech specs: 1x L Motor 3x Pneumatic cylinders, 2x 11x2 to lift & lower the trailer bed, and a 1x5 cylinder to open & close the trailer flap. 10x Wheels, 8 on the tractor in a dually configuration, & 4 on the trailer. Well, now on to pictures! All pictures & more are available at my BrickLink
  7. Hello all! I was reading the forum for quite a long now, but it didn't feel quite right to post, without proper introduction. Well, finally, let me present my first MOC here on Eurobricks: Remotely Controlled Mecalac MTX Here is the quick video showing the operation: More Pictures: Description Statistics: Weight: ~1500 g Part Count: ~1400 Dimensions: L x W x H (without boom): 300 x 140 x 220 mm Remotely Controlled Functions: Driving & Articulated Steering Continuous 360 Slewing Elevation of 1st boom section ( mLA) Elevation of 2nd boom section (LA) Sweep of the 3rd section (mLA) Elevation of the 4th section (mLA) Articulation of a Bucket (mLA) Power Functions components: 3 x L Motors 1 x Servo Motor 1 x M Motor 3 x IR Receiver 1 x AA Battery Box 1 x 9V Battery Box The color-coded render showing the drivetrain: The functions are distributed by two gearboxes - one located in the chassis with two clutches, and one in the superstructure with three clutches. The chassis gearbox is switched using the M-motor through a worm gear. The same motor controls the deployment of outriggers (Similar idea is used by Pipasseyoyo in his dump truck When the outriggers are raised, the two L motors in the chassis provide driving and steering. After the outriggers are deployed, motors drive two clutches in the superstructure gearbox. The third clutch is driven by the L - Motor located in the driver's cabin. The superstructure gearbox is controlled by a Servo. To make it work I have to get rid of most beloved Servo feature - return-to-center. Otherwise, the gearbox will be switched to neutral, each time the controls are released. The solution turned out to be pretty easy: One may say, that using the M-Motor for the gearbox would be easier and more compact. But I like the limited degree of rotation provided by the Servo, so I don't need to stop the motor precisely at the right moment. And, to be honest, after I came up with the Servo solution, I liked so much, that I'd decided to implement it besides some shortcomings. As a result, 8 functions are driven by 3 motors. But the controll requires some practice, since you need to switch the gearboxes often. And as you can see fro the video it is extremely slow. So you can't actually 'play' with it. But it works. About the development process (you can skip it, if it is enough reading for you; I haven't found a way to make a cut) After I had completed my first working MOC - a Unimog truck, I was looking to build something more technically complex, so I can put to a good use all the gears and u-joints I have accumulated in my parts collection. Well I have achieved that. In the course of the project I have ordered the additional u-joints together with a lot of gears four times, and then a little more. The inspiration came from the ingenious brick-sorting excavator by IbrahimFitzGibbon. About the same time I came across Blackbirs's Technicopedia, and was impressed with the old sets, where often several functions will be controlled by a single motor using some crazy switching mechanism. And when while on trip to Germany I saw it. Mecalac 12MTX excavator working on a narrow street in all its glory. This is it. Compact, complex, with tons of functions packed in a small space. I knew, I must build it. After I scaled the blueprints to the medium wheels I had at the moment (68.7x34R), it was obvious that the implementation at this scale will be almost impossible. Will all the motors and gearbox clutches in place where was almost no space for the structure or drive-lines. So I decided to go for it. It was extremely hard. You know, when you are completely sick of it, but something keeps you going. Every time I would start working on a new mechanism, the first version will be two or three times bigger than it should. And when after dozens of iterations it will fit, but won't work. So optimization, optimization and optimization. I have 58 LDD files for that thing, but they only reflect major changes, when I needed to start from scratch. In total it took almost three years. The main challenge was the boom. Mecalac boom have five articulation points instead of three in a traditional excavator. That means that I needed to pass four drive lines through the first rotational axis and three through the second one. Anyone who built the excavator knows how difficult it it is. I wasn't able to use u-joint for the first two axes because of the limited articulation. Additional challenge was the implementation of the third articulation point, since the axis of rotation is for that one is rotated at 90 degrees to the previous axis, and they are only few studs apart. Figuring out the way to twist the axes took a loong time. At the end I am satisfied with the result. But not more than that. It works. But you can't play with it. Because all the arm functions have a very long drive lines with a lot of gears, I had to heavily gear it down to be able to overcome all the friction. So the arm functions are extremely slow. But all the ideas work. I I really love same places in the model. Like the Servo with no-return-to-center clutch, chassis gearbox switch coupled with outriggers deployment, three u-joint passing the chassis' articulation axis at angles. There, I finally used that teeth on the old gearbox gears. Coupled with old style half bushes, it allows driving the axle directly (see the orange drive line below). And I hate Yellow color now.
  8. Hi, Check out my newest creation!
  9. Hi, I have recently started a tracked vehicle project. I have made a few other topics about it, building it etc. I was wondering if anyone has made a vehicle then turned around and made it articulated. (Especially tracked) I also need tips on how to do this. Thanks

    MOC: WIP. A perfect 317.

    This is My Own Train 10205-1. Yes really. Well it did start out that way; - I purchased it off Bricklink, - a slightly played with 10205-1 with no box, but with instructions, with crooked stickers and all parts present with one or two minor substitutions. It's been hanging around a while in a large clip top plastic bag waiting for me to do something with it. It came to pass that I'd decided it was time for me to learn about PF so I decided to use the MOT 10205-1 as a guinea pig, - only I didn't fancy having a steam loco with diesel trucks. Easy peasy on went eight BBB medium wheels and four sets of Technic coupling rods, and somehow it all happened from there. It began with the tender. The standard MOT tender is a poor wee underfed thing that could barely fit one 'AA' battery. I had a 9volt battery case that took 'AA' batteries so I decided to use it, basically building the 8 wide tender around the battery case and mounting it all on two four wheel trucks. An 8 wide tender needs an 8 wide cab to follow after and so it went from there. I wanted a good sized cab to act as a junction box and a place to put the PF receiver unit and the new 8 wide cab is 2 studs longer than standard not counting the roof overhang or fall plate. The boiler is 1 stud longer than standard and overall I think the loco's proportions are reasonably good. My new No: 317 looks like a Mallet, but is really a Meyer as both power bogies are fully articulated. I chickened out with trying to fit connecting rods for the present as I would like to get the loco running properly first and if it looks to be a really useful engine I'll buy a set of Zephyr's rods for it and finish everything off properly. Still a few little jobs to do such as sorting out the tender coupling and fitting the PF receiver once it arrives. The cab roof needs some more curved slopes to match the ones in the middle as I'd run out and made do with the 2x4 ones. The red bands on the domes and cylinders came about because I didn't have enough 2x2 circular plates in black so I used the red ones. It was supposed to be just a temporary fix, but now I'm thinking the red bands can stay. I've only just now realised that I'm going to need a turntable now so I'd better hurry up and finish my two road engine shed so I can do a proper survey and peg out where it's going to be put. There will be more to come with No: 317 and as I make progress I'll post more pictures and updates here.
  11. Hi Everyone I have been trying to find info on the Rolligon, but not having much luck at all. My main query is to find out how the steering works in an 8x8 version. As you can see from the very small pics below obviously turns in the middle but does it pivot up and down to allow for hills/ terrain? Does it still "roll" as well? Any info or advice would be great, Thanks!
  12. Hi. it's been a long time since last moc. on account of me moving. however i have been working on a articulated truck inspired by the Uniknick. like this one: Here it is: the model features (at the moment): - XL-motor for steering. - 2 x NXT motors for drive. Features i would like to implement: - front and rear hitch. - winch. i also mean to build a unimog u4000 or 402 cab for it. however i am not too good at building those sorts of things. i hope you can help me there. Here is the LDD file: http://www.brickshel...thout_motor.lxf Enjoy! Will upload more pictures to my brickshelf soon.
