Dear all, Another year, another crane. This time it's a crane in the size range of the 42042. The crane hase the same track size and width, and shares more or less the same frame, but this time in black, also I decided for now not to motorize the tracks. The body has also more or less the same size and structure as the 42042, but I tried to make the body less wide. The crane has 4 motors, 2 L-motors for the 2 winches on top, one XL-motor for slewing and 1 angular motor for the 3rd winch. They're all housed in the body and connected to the battery box aft of the main body. The 2 ballast boxes each hold 150grams of ballast. The building showed me it's indeed difficult to make a rugged build, due to the flexing of lego parts because of sideways movement of the crane boom. this was almost complete fixed with the installation of the 2 springs and some additionals beams for support at the front of the body. For now the crane can lift 350 grams in its highest and most comfortable position. The cabin has an openable door and can be tilted upwards(not seen here) I used the good old lego metal hook with 50 g of ballast stuck to it, I didn't use a turntable this time because it would make the hook too bulky and too big Here's a view of the panels removed, you can see the placement of the motors and the winches, the winch of the hook is directly connected to the angular motor, without any gears The last photo is for scale, in it's highest position the crane reaches 1,35 m, additional sections can offcourse be added

[ENTRY] 1873 & 6258 Pirate Treasure & Smuggler's Shanty - Remake 2023
MyFirstMOC-Hun posted a topic in Pirate MOCs
Hello! This time I combined two classic sets, Pirate Treasure 1873 and Smuggler's Shanty 6258. This is a small island where life goes on and there are traces of greed and a few skeletons to show for it. There are also several hiding places to stash your loot, gold bars and gold coins. Soldiers about to dock bring the pirates their pay for a job well done. On the island there is a fisherman who sells his wares, a tavern of course, a shelter for the captain, a defensive cannon to keep out intruders, at least until the pirates escape. But are there still drunks lying on the beach who can't understand how the rum ran out again? And let's not forget the old man pushing his wages on the little cart, waving to the barman that he'll soon be able to pour another batch of wine. Flickr Instagram -

Hello builders, I've started the long process of reorganizing my LEGO parts and I want to get back into constructing LEGO MOCs. I'm looking for inspiration. I'm interested in MOCs of a 16x32 foundation. Whilst I understand some may see this size as too small, I feel it's good for conserving precious space. I'm wanting to construct a street, with buildings opposite side. If anyone has any decent 16x32 foundation MOCs that they would like to share, please feel free. 😊 A quick search: scarovich - [MOC] Pizza Shop - 16x32 modular (will edit this post)

Hello! I'm running out of sets (especially since there's more than one that someone else has already made and I don't think I could create a better one) that I'd like to revisit, but this one is still here. And this is the 6246 Crocodile Cage remake. I increased the set dimensions a bit to get the detail I had in my head. I added one more native, because I think there's plenty of room for it in this area. The top of the set is modular and there are also some movable parts, like the rock that hides a golden trophy or the secret door at the back of the cave. In the cave are the skeletons of a couple of stranded pirates and the skulls of two natives who died in battle. Instagram Flickr

[MOC] Lissajous Machine (but failed)
Carsten Svendsen posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everyone I haven't posted a new MOC in a long time, mainly because I haven't had the interest lately. This thing has been with me for years now, trying to get it to work, and it is one of those projects that causes so many headaches and will never work properly, no matter what you do. So this video is the result of straight up agony, and I do not think I'll be revisiting this again. I haven't disassembled it because I hadn't got the time before putting all my LEGO in storage for a few years. So "enjoy" my failure See a few photos here But maybe let me tell a bit about this contraption as if it had worked alright: The first challenge was to figure out a soutable gear ratio. I chose to make the 2nd fastest (orange) the 1:1 gearing from the motor as then the slowest was still able to spin somewhat comfortably. The size of the circles and spacings are all a function of the LEGO brick arches and discs. To get the arms in the right location, I had to offset them by 0.5 studs, which was easy enough with some 4-pin connectors with axle hole. Then the challenging bit - designing the gear ratios to also fit inside the box. It looked like there was a lot of room, but I had to use many more gears than what I thought, so this wasn't so easy either. Also here, I had to space them by 0.5 studs. I had initially only planned to power the red (the fast) ends which would be 3 motors, but there was just no power at the slow end when I did this, so back to the drawing board. I then decided to power each side from either end, which meant I had to add gearing in the small corners - 1:1 for one end, and 1:5 on the other, in some cases. The slow end was the hardest to figure out and need quite a few more gears. Now for the fun part, to see if it works! Turn on the motors and yup, everything is running at a different speed, as I expected. This is not good, as the axles will keep twisting more and more, or gears will skip. So I had to figure out a solution to sync them up. I went with Power Up, and no matter what I did, there was no way to sync them up in software. I had to write my own code, and I'm not good enough for that. It would work sometimes, but mostly just with 3 motors for some reason. So in the very end, I decided to link them up physically, but this was a challenge in itself. They are long distances, what's the best way? I ended up with the ol' steam engine solution and just multiplied that by 4. And it works great! As long as nothing is stalled anywhere, because then gears will tick over and over. In the video, you can hear this, and it's probably because those gears already need a replacement. But it is so darn hard to do. Lastly, decoration - this was already decided on well before I was halfway through with the project. It had to bricks, because of the arches. Building the long panels was easy, but building the corners took some more skill. Not too much it turns out - I looked for help here in Eurobricks and no one would help. What seems simple to you, may not be simple for me. Anyway, I ended up with some lightsabers underneath and some clips to hold the corners in place. They aren't perfect, but I guess nothing in life ever is. Also the large panels move around all the time, I think the tolerances on those arches aren't actually perfectly round, they seem kind of oval. What went wrong with the demonstration though, was that a CV joint on the backside had popped out, and so the whole left side of it wasn't spinning to begin with, thus being the source of most of the issues shown. And then I also only bought a pack of 24 marker pens, when I needed 25, luckily I had one extra lying around that fit the 1x1 LEGO dimensions. And acrylic is not cheap! 2 sheets of 0.3mm each. But I guess that's nothing compared to all of the black panels, liftarms and plates and bricks that I had to buy. Failure all around. If anything it was a good learning experience. -
[TC 25] 42055 C-Model: Mining tipper truck (rat race)
Timewhatistime posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi Eurobrickers, I really like the idea of the TC 25 shrinking contest, but unfortunately I won't be able to participate. This contest will give us a lot of creative mocs. In some cases the participants will choose the same set, which will give the opportunity to compare and appreciate the entries. Nice! Back in 2017, I built a simple small C-Model of (part of) the BWE set 42055: A shrinked version of the mining truck which was included in this set. It was also available as a single set (42035) some time before - rather this is the colour scheme my little C-model corresponds to due to the yellow panel. The main challenge was that it needed 4 wheels (= 12 t bevel gears), but 42055 includes (hard to believe...) only 3 pins for that purpose (tan 2L axle pins without friction tan). ;-) So the fourth axle ist a brown 3L axle with stop. Probably it won't meet the specifications of the contest because of the electric function... ;-) https://brickshelf.com/cgi-bin/gallery.cgi?i=6492892 Mining Truck 42055 C-model https://brickshelf.com/cgi-bin/gallery.cgi?f=569964 More pictures I didn't manage to insert a brickshelf-picture in this topic, so just use the links in case of interest. :-( -
Hello! This time I reworked the 6254 Rocky Reef set for the Classic Pirates tournament. There are two pirates and a skeleton in the set. The island and the cave were once inhabited by natives, but the pirates felt it would be a great island to hide their treasure and took over the place. The only traces of the ancient inhabitants are the small totem detail left at the back of the cave and the skeleton in the cave. Of course, what pirates would they be if they didn't have a little place to hide an emerald right now. The roof of the cave can also be removed for playability, and there is a small jetty on the island, if you bring supplies for the two pirates by boat, you can untie it. Instagram Flickr

XL two track railway locomotive shed (finished in real bricks 10/4/23)
Murdoch17 posted a topic in LEGO Train Tech
This model was originally built by my father around 2005 / 2006 for an old 9v-style MOC steam engine we built together based off set 7722. It was three tracks long and one track wide at first, but I reworked it to be five tracks long and two tracks wide in late 2015. Both of these earlier models were almost totally black with a little splash of red. Fast forward to 2023: I have remodeled the MOC almost entirely. I've changed most of the black to tan, blocking up the lowest row of windows, and changing the red doors to light gray. The roof remains untouched except for twelve parts above the doors / back wall. The building is a little under 5 tracks long, or about 75 studs in length. The maximum side clearance is good enough for a 10 stud wide model (no overhang at that width) while the trains can be no more than 11 bricks tall. Here we see the rear of the MOC. The roof comes off and the inside has a new raised platform to allow for maintenance to the engines. (before it was just totally empty) This model can hold most of my steam engine designs (not all at once of course!), although it is probably too short in length for some of my diesel units. The dismantled 2015 version is in the spoiler tag. EDIT 10/4/23: Real pictures added, entire post restructured. Thoughts? -
[Entry] 1492 Battle Cove 2.0 Ahoy there scallywags. Introducing my modern version of that classic Pirate polybag 1492 Battle Cove. Lego inflation is real and sets are larger and more expensive then they used to be, as such my moc has 104 pieces compared to the 26 pieces found in the original set. The key features of the set are a small brick fortification on a tropical beach underneath a palm tree, that is protected by a cannon and shark infested waters. I chose to keep the plant life to a minimum like in a official Lego set. I wanted this set to feel less like a AFOL moc and more like a set released by Lego. There are some really realistic palm tree mocs on this site. Likewise the fortification walls can be made to look more realistic if you use plates instead of bricks, however that really increases the part count. As a added bonus play feature, since the walls sit on only 2 studs, they can fall down if they receive a direct hit from cannon shells fired from a ship at sea. ++++++++++++++++++++++++++++++++++++++++++++++++++ For the AFOLS who like brick built cannons, I also did a version of Battle cove with my 18 piece brick built cannon. I personally like the look of brick built cannons for their size and affordability. However if Lego were to release more pirate sets, I think they would stick with the projectile launchers, as they are fun to play with. ++++++++++++++++++++++++++++++++++++++++++++++++++ =============------===================-------==============-----======================------============ As always thank you checking out my moc, and please feel free to leave any comments or suggestions. may you have fair winds and following seas

Model of a New Flyer XD40 transit bus in MTA livery. The model has roughly 3800 pieces. Features motorized drive, steering with working steering wheel, passenger doors, and a removable Cummins engine model with moving pistons. Functions/features: Drive Steering with working steering wheel Remotely controlled doors Removable Cummins engine model with moving pistons Instructions available on Rebrickable: https://rebrickable.com/mocs/MOC-153565/JLiu15/2015-new-flyer-xd40-mta-bus/#details Because my NJ Transit New Flyer XD60 model was a huge success, I decided to reuse my design and make another Xcelsior model - this time a XD40 in MTA colors. Unlike my NJT XD60 model which has the livery done entirely using stickers, the blue stripe livery MTA used prior to 2016 is easy to design with blue LEGO pieces. As a result, the model is recognizable as a MTA bus even without stickers, which is why I specifically included "MTA Bus" in the name. The model is not simply my XD60 model cut shorter. The chassis is redesigned from scratch. The front and rear axles are placed at a half-stud offset to allow for smaller wheel arches. The XL motor for drive is placed in front of the rear axle instead of behind it to allow space for the Cummins engine model. The battery is placed much higher and is accessible by removing the upper rear body panel. I added a switch on the roof to allow the battery to be turned on without removing the body panel, so it only needs to be removed for charging. There are also no supports in the chassis for the rear door as the rear door on MTA Xcelsiors open outwards, and the front of the chassis is redesigned to accommodate both the mini linear actuator for the front door and the connection from the steering wheel to the Servo motor for a working steering wheel. Lastly, the chassis is also designed to specifically accommodate for MTA's seating layout, most notably with only a single seat per row on one side in the low floor section. Like my XD60 model, there is also a roof frame that holds both motors for the doors as well as the rear door mechanism (which uses the same general principle as the inward-opening front door despite opening outwards). The roof frame is attached to the chassis using beams, making for a robust "skeleton" that the body is built around. The bodywork has also been redesigned in several places. The wheel arches are now smaller due to the half stud offset of the front and rear axles, although I had to use inverted slope pieces instead of arch pieces to allow the blue stripe to be built entirely in LEGO. This means the wheel arches are not perfectly curved here, but I found it to be a fair compromise for making the entire blue stripe in LEGO. The front lower body panel is one stud higher here compared to my XD60 model, although it kind of makes it look like the front of a MTA Orion VII NG (MTA Xcelsiors in the blue stripe livery have the bottom edge of the front windshield curve downward slightly, and such a curve would be very difficult to model in LEGO at this scale. The rear body panels use a simpler and more robust design, the front roofline curves are angled slightly outward (the space between them was increased by 2 studs), and the side body panels are attached to the chassis/roof frame using white 1x1 Technic bricks with axle hole and part 27940 in white. This allows for a seamless body without pins showing; part 27940 in white was not yet available while my XD60 model was being built. The roof is primarily built using 6x6 tiles this time instead of 5x11 Technic panels - because MTA's 2015 XD40s do not feature a full roofline, the transition from the side body panels to the roof is much more noticeable here which is why I went with the tiles. The model's functions all worked well. The single XL motor was more than enough to power the model, especially considering this model is lighter than my XD60 model. Although the moving pistons on the Cummins engine model are not easily visible (there's one piston visible under the last row of seats), I am happy that I was able to add some additional functionality to this model. And because the pistons are made using half bushes, the engine makes a nice sound while the drive motor is running. While designing my XD60 model I thought there was too little space in the front to incorporate a working steering wheel without compromising the rigidity of the chassis, but I was able to connect the steering wheel to the Servo motor just fine here. There is less reinforcement immediately in front of the front wheels so they don't collide with anything when steering, but the side body panels keep everything robust. I did not test the rear door mechanism before installing it on the model so I was concerned how well it will perform, but it is usually able to open the rear door fully with each door panel rotating 90 degrees. Sometimes the mechanism gets stuck while opening the door, but reinforcing the pieces a little usually solves the problem. While at first glance this MOC looks like my XD60 model shortened and without an articulation joint, it was really a new MOC from scratch. The chassis is completely redesigned and has little resemblance to the chassis of my XD60 model even without accounting for the lack of the articulation joint and a third axle. The bodywork was also improved in several places. All of the functions performed as expected, and the finished model is easily recognizable as a MTA XD40 even without stickers. Speaking of which, I decided to make my model bus 7225 operating out of Grand Avenue Depot in Brooklyn signed for route B62. Overall I am very satisfied with how my second bus MOC turned out, and I plan to continue making bus MOCs in the future, with one already in progress. Video: Photos: Brickworld Chicago Photos: -
two 1930s American freight trains with ten new freight car MOCs - real world models
Murdoch17 posted a topic in LEGO Train Tech
I've had these ten train cars built for months now (years in some cases!) and thought I'd better upload them before I forgot again. The two old-fashioned freight trains consist of the following items (in no particular order): - red standard caboose - two boxcars - three generic open-top wagons - flatcar with rail load - OCTAN fuel tank car - livestock car with cow - green streamlined caboose This green 1930's streamlined caboose was inspired by a very similar real-world Wabash caboose located on the Katy Rail-Trail at St. Charles, Missouri. This caboose model (along with the green streamlined one) is inspired build-wise by the Katy Caboose (as in, "The Caboose who got Loose" from the children's book) model I copied in late 2021 from TrainedBricks' MOC. These two nearly-identical boxcars were inspired by set 7597 (Western Train Chase) from the 2010 Toy Story 3 line. They are 99% the same except for colors in a few places, as not many train cars are identical to each other - especially freight! The simplest car of all: a flat car with railroad track / rails strapped to the top in four rows. These three generic wagons cars are actually British Railways plank wagon models, not American at all... but they work well enough for me! These cars were designed by the_chestertonian, but sadly he deleted all his photos. This is just a quickly-mocked up tanker car in OCTAN colors. It's nothing too fancy, but it does look good. (to me at least) This livestock car was heavily inspired by 2014 CITY set 60052 (Cargo Train) but with a roof for more realism. I can now understand why LEGO left it open top in the set, but I managed to make it work. The roof (which was designed with the same look as the boxcars) is even removable and the ramps fold down so you can take out the cow. Believe it or not, the freight cars wouldn't fit in this box in any other configuration! That's all I have... Thoughts? -
Hello! This is a redesigned version of the 6259 set, with a more modern look. In addition to the two soldiers, the set also features a captured pirate. A small desk, treasure chest and escape route from the prison have also been replaced. The roof of the building is removable and modular. Instagram Flickr

Hello! I entered the competition to make a remake of the 1889 Lego Pirates set. Hidden in a small cave in the rock is a treasure chest full of diamonds, covered by a door made of vegetation. But just in case someone does find the treasure, a small gold bar has been hidden away as an emergency stash. More pictures on my insta account, because it simply won't allow more. MyFirstMOC Insta

Welcome to the NeRDZ. What is the NeRDZ.? It is more of a concept of myself wrapped in a design that should be as appealing as possible than just a building. The thought behind it is that we live in a time in which we are increasingly forgoing real contacts. We are using digital ways to pursue and share our interests - without necessarily realizing how socially lonely we are. Because comics & e-sports have now arrived in the mainstream and there is also a growing adult community of brick fans, the NERDZ should create an opportunity to bring people together at one place. It's basically a kind of bar where comics, video games, briceks and music are the focus. To linger with old friends, to find new friends and of course to have a lot of fun. It is aimed at anyone who is enthusiastic about these hobbies and would like to meet like-minded people - but also at anyone else who finds fun in these topics or would like to get to know them. Other ideas for this concept that are not incorporated in this project could include: - the organization of regular competitions (e.g. MOCing challenge, karaoke night with movie songs or a tournament with the game console) - A sale of MOCs I Theme days I Sevice employees in superhero outfits (a classic space outfit was used instead in this version) - a lot more About the building: The building was constructed about a year ago. It was actually designed for another competition, but after finishing my project there I distanced myself from taking part again immediately. As it was designed without IP, the BDP represents a suitable opportunity to resume the project. Link: https://www.bricklink.com/v3/designer-program/series-2/763/NeRDZ.-[Comics-&-Bricks]-[Coffee-&-Bar] Real life build: For the BDP, some adjustments were made compared to the real built version: parts and colors were adapted to the BDP palette, some parts (which I didn't own) were used. In addition, the number of parts has been reduced without causing any disadvantages in terms of presentation or stability The set now includes almost 2.000 pieces (1.999), six minifigures (two employees / four guests) and three animals (dog, cat and a spider as signal sign – an Easter Egg, maybe you’ll figure it out). There are no custom stickers - I wanted to keep it simple and used the BDP range instead. The building can be opened completely and the roofs can also be removed - to explore each area extensively. In detail, these areas are: - Front building with outdoor area, main entrance, snack bar with stone oven, bathroom and hallway - Construction corner with brick table and some miniscale MOCs - Gaming and comic/book section - Karaoke area with dance floor As usual, I tried to include a lot of details. Therefore, the list above is certainly to be supplemented. I hope I was able to get you excited about this project and to bring you closer to the idea of the NeRDZ. Of course I would be very happy about your vote and a short comment. Thanks for "listening" and see you soon :) Yours, Tobi aka MM

As promised, some "fancier" pictures of my modular LEGO Harry Potter Three Broomsticks MOC. Since a lot of you asked - if you are looking to build this yourself or are curious how it was built, you can check the 7 part video series over on my YouTube channel, where the building progress is shown in full detail. https://www.youtube.com/@Uniqueorn/ While you are there, should you feel like it, throw me a like or a comment. It is greatly appreciated! Also, if you like to follow the progress on my other LEGO builds, you can always follow me. Happy building! -
I have been trying to find a place to post Mocs I have built from some of the designers here. (first to admit im pretty useless at anything computer related and may have missed something). But if there isn't such a place, is it possible to add one. ? A place where building, even an old, moc of someone's wouldn't require a dreaded " old post bump" to show it? Anyway that's all I have, and if I have completely missed a spot to do this, I guess this post is mute.......

Built this SHIP last night using some advanced building techniques, but I'm not sure what the right term for this type of hull design is. It has a lot in common with a Cog, but the curve on the prow is the wrong shape - wondering if anyone can help me figure out a more accurate classification. It's definitely a merchant vessel as the primary cargo is animals.

Model of a Mack Granite truck equipped with a boom and flatbed. Features drive, steering, full suspension, motorized boom elevation, extension, and rotation, winch, and extending/lowering outriggers. Functions/features: Drive Steering Full suspension Boom elevation Boom extension Boom rotation Winch Outriggers Instructions available on Rebrickable: https://rebrickable.com/mocs/MOC-150955/JLiu15/mack-granite-boom-truck/#details After the 4-output distribution gearbox on my MCI D4500CT Commuter Coach model proved to be ineffective, I didn't want to simply abandon the gearbox design. I decided that I was going to tweak the gearbox a little to be used in a new MOC. I had wanted to use the same suspension setup for my MCI D4500CT model as a test bed for the suspension design, so I settled on incorporating the gearbox into a truck model. A boom truck like this is a MOC I had wanted to make for quite some time, as I see plenty of them in the US but not that many MOCs of them. Because the turntable for the boom is placed higher up, it leaves more room to route gears/axles from the gearbox to the 4 functions it controls. Because the gearbox sits in the heart of the chassis between the outriggers and rear axles, the chassis is built very densely. The gearbox makes use of two Control+ L motors: one for shifting and one for driving the output functions. The drive motor (a Control+ XL motor) sits directly behind the gearbox, and drive is transferred to the rear axles via an extendable CV joint. The drivetrain is geared down after the CV joint to reduce the amount of torque applied to it. Lastly, there is another Control+ L motor for steering which is built into the front axle. I designed the suspension (a simple live axle for all 3 axles) entirely in Stud.io before building it physically, so I had no idea how it would perform upon building it. However, the entire setup worked flawlessly, and there are no issues with drive transmission into the suspended rear axles. My initial plan for this MOC was to just build it as a generic US-style truck, but upon finishing the cab someone said it resembled a Mack Granite, so I modified the cab to actually make it based on the Mack Granite with the Mack Bulldog emblem from the 42078 Mack Anthem set in the front. A number of metallic silver elements are used in the front, although due to the relatively low number of pieces available in that color there is still plenty of gray in the front (such as the bumper). The Control+ hub is placed in the back of the cab and is removable for battery replacement by removing the roof, as the hub and roof are attached to each other. This means the sides of the cab must be sturdy to compensate for the relatively loosely attached roof, so the doors do not open on this model. I decided to build the cab in dark blue, a color I have not used much before, as I now have a sizeable collection of dark blue pieces from the 42083 and 42154 sets. I built the boom in yellow to contrast with the dark blue cab. The boom is built around 3x19 frames covered with tiles. Their abundance of pin holes makes them a good candidate for crane booms. It was difficult routing the two motorized functions through the turntable and into the boom, as two separate axle functions must pass through a small space. Because only two axle functions can be routed through a turntable, I had to make the winch manually operated with a ratchet mechanism. I was initially concerned about the weight of the boom, and while the boom does tend to lean forward during the elevation process, everything remains intact even at maximum elevation and extension and the range of the boom is quite impressive. There are no stoppers for the boom rotation, so the boom can theoretically rotate infinitely as there are no wires going through the turntable. The outriggers, however, were a weak point for the model as they are quite flimsy and are unable to lift the truck off the ground without substantial bending, so I limited the outriggers' legs extension to where they are able to make contact with the ground. Additionally, I should have geared down the mechanism substantially more, but a modification would require essentially rebuilding the chassis from scratch. As a result, I set the gearbox motor responsible for driving the gearbox functions slightly below maximum speed. I had wanted to be able to control the gearbox functions with a single touch (e.g. pressing one button shifts the gearbox then drives it in a given direction) but was not able to figure it out so I went with a much more straightforward (albeit more difficult to use) controller setup. A single slider is used to drive the gearbox functions, and three buttons are used to shift the gearbox (up 90 degrees, down 90 degrees, and return to one endpoint). I have to keep in mind the position of the gearbox while controlling the model, but the setup overall worked well. Overall, this was a MOC that had plenty of mechanical complexity, but certain functions could've been designed better. While all of the functions work as intended, the boom leans forward quite a bit when the boom elevates and the outriggers cannot lift the truck off the ground. The front axle could've also been reinforced better, as during the steering calibration process the steering pinion gear often skips a tooth. Despite the drawbacks of this MOC, it still largely met my expectations as the drivetrain and suspension worked flawlessly and the dark blue/yellow color scheme worked well. Video: Photos:
