Looking For Best 4-Speed Sequential RC Gearbox
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This is my second post on the EuroBricks community and another question asking for as much help as I can get to master the art of the technic gearbox. Like I said in my previous post, for my Lexus GX EV3 4x4 SUV, I tried my best to use Sariel's 4-speed sequential and it ultimately failed on me. Quoting one of my replies... I would be relieved if I could finally finish this creation after five months of difficulty. Here are some pictures of the entire chassis. I said before that the issues with this was that the gears clicked a ridiculous amount at the highest gears which stopped the car from moving. (Hence the reason why the transmission I want needs to have a clutch gear to absorb the large amount of torque) -
Hello Guys! I am trying to find grease in America that would be safe to use on Lego 12v motors (from the 80s) without paying horrendous prices. I am wondering if anyone has found suitable grease in the U.S. I have had a few people tell e about ROCO 10905 but that would be $20 to have it shipped over here from Europe. Thanks -RailCo

The 10 x 18 bucket in Black is used in this set, i am wondering if the older type in Yellow could be used instead? Part #2814: https://www.bricklink.com/v2/catalog/catalogitem.page?P=2814#T=C&C=3 -
Suspension Ideas?
TechnicRCRacer posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi, I have been working on a new MOC (which I will leave as a surprise) and I can't seem to build a tiny rear suspension with a buggy motor driving it. I have seen these in other models before, but it is just too hard to reverse-engineer it. I am trying to make it within 15L by 15L. Help is appreciated -
Please let me know how I would get my MOC photos down to 10.24 KB. I can't seem to find a way to do this. I have seen awesome people post their MOCS here. I can't seem to get it to the file size. Thank you for taking the time to read my post.

Gear Grinding/Clicking Issue In Gearbox (EV3)
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'm building a SUV drivetrain for my Lexus GX EV3 project that has independent suspension, four-wheel-drive, and a four-speed gearbox with a medium EV3 motor that shifts the gears. Unfortunately, after testing the drivetrain, I found that when in 3rd or 4th gear, the gears make a clicking noise when moving forward and then straight to backward. However, this clicking somewhat occurs less when going from reverse to forward. This clicking really "grinds my gears" and I don't know what to do to stop the gears from clicking. My gearbox is a custom version of Sariel's four-speed sequential that is fit for the vehicle I am building. The input in the transmission is switched to provide more speed. Two large EV3 motors drive the input. I've noticed that when the vehicle stops, it goes the opposite direction for a little bit. Also, like I already said, this clicking only happens in 3rd or 4th gear, but mostly the 4th gear since it brings the most speed. I tried to solve this clicking with different gears and whatnot, but no matter what they still clicked when the vehicle moved forward to backward. The motors and the gearing also bring a lot of torque as much as it brings speed, and this might be one of the problems. Is there any way I can solve this issue so the gear clicking will stop in this situation (moving foward and then straight to backward) for now on? Here's a photo of the bottom of the drivetrain. Thank you in advance for any assistance that you may be able to provide! -
Hello, I am reaching out to all 12v train users. I recently purchased and received a 12v train (the 7725). Unfortunately the motor is dead, I put it on the track after building the whole model and setting all the track up to find it not moving. At first I thought maybe if it hadn't run in awhile it would need a little help. That didn't work so I tried it by just connecting a wire to the motor itself and gently moved the wheels. The motor started to produce a light smoke so I immediately shut the power off and haven't tried anything since. I did see some life though at one point, it did move about 1/16 of a turn at best and I could hear it trying to move. If the seller is cooperative hopefully I can work something out with him. If not I was hoping many people on this forum could lead me in the right direction. Here is what I know about the motor: It looks to have been opened before. It is the version with the separate bogie pin. From what I can see there is some hair spun around the axles. I am wondering if I need to completely give up on the motor or if there is a way to fix or replace just the motor inside. I am really lost and would love any help that someone could give me. I looked for awhile but I haven't found a post about someone having the same problem as me. Even if someone has a broken lego casing for the motor but there electrics still work I could be interested in that as well. Thanks, -RailCo

Hello all, I have a quick question about the BBB medium wheels. I noticed many people have made MOCs with them and have been able to make the non-flanged wheel and the flanged wheels (i.e. an 0-6-0) be right next to each other. I am not sure how people did this because my non flanged wheel is the same depth as the flanged wheels. Also, I was wondering how people put traction tires on these wheels. Thanks! -RailCo

[HELP] Buzzing Motors with SBrick
Saberwing40k posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Well, I recently took the plunge, and purchased a few Sbricks for use in my creations. In order to test the setup, I connected some motors, and used a profile I threw together. The setup I used has 2 SBricks being controlled by my device at the same time, and my problem is that, with one of the SBricks, I have two M motors hooked up to it, and when I activate them, they run just fine, but when I let the joystick return to center, the motors buzz, almost as if the SBrick is not fully shutting them off. I'm not sure if it's a problem with the SBrick, or not, as it is one I tested before, and it had trouble with controlling my other motors. Is there a setting I am not aware of that would fix this? Has anyone else had this issue? Update: I tested it, and it seems to be an issue with the brick, although, in a bizzaro twist, I don't have the problem with sliders, only when those channels are controlled by joysticks. -
Truss design - are these ones OK?
Captainowie posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi folks. I need some advice from people who have experience building large structures. I'm looking at building a GBC module that takes balls across a gap between two tables, that's high enough to walk under. I need a vertical lift of about 1.3m, and a horizontal travel of about 1m. Now, this would be by far the largest model I've ever undertaken, so my intention is to design the thing in LDraw before I buy anything. This means I can't see how sturdy the structure actually is, so I'm asking you all whether what I've designed so far is sensible. I've got two slightly different truss designs. One that I think would go better for the vertical parts, and one for the horizontal. Each is a single unit 16 studs in length, with the idea that you join as many units together as you need to get the length/height required. First, the vertical segment: And what three of them together look like: I feel that this truss is going to be strong in compression/tension, but all that space in the middle makes me nervous - is the 5x7 frame box going to be solid enough to make it strong in torsion as well? Next, the horizontal segment: And three of them together: This one I think would be quite resistant to bending in the up/down direction (exactly what you want for a horizontal beam supported at its ends), less so in the side/side direction, but also strong in compression/tension. This one would be somewhat heavier than the other - overkill? or is the extra strength warranted? I'd appreciate your thoughts on these two truss designs. If you want to see the .ldr file that these images came from, it's here. Regards Owen. P.S. If anybody wants to take these and make them into a tower crane for [TC8], go right ahead. EDIT: Yes, I know there are no triangles. I am relying on the rigidity provided by the 5x7 frames in place of diagonal bracing. -
One thing I like to do is make MOCs, but design them as if they were official sets. One example here is my Senate Duel MOC: However, it has no play features at all, apart from the ability to slide around (thanks to boat bottoms) and the ability for minifigs to sit down, both of which are very bland. The ability for minifigs to sit down could be advertised as a play feature, but I still need 1-2 more. Does anyone have any ideas? :) Thanks in advance, and no, clipping stud shooters on the side is not an option VaderFan2187

[HELP] Crawler Front Axle
offroadcreations posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello, I am trying to reverse-engineer a MOC by RM8. I am having trouble making the front suspension and steering sturdy. Does anyone have ay ideas of how to make it more stable? Here is what I have so far: Any advice is appriciated. Thanks in advance. Here is the video the truck is in. -
Hello! I have noticed recently that I can't buy any Lego from any other amazon site than my home country. I am curious why this is? Also since I cannot buy Lego internationally anymore from amazon, does anyone know of other shops from the UK or Europe that ship to the U.S. internationally they can recommend. All suggestions appreciated -RailCo

(Help) Extendable Outriggers Without Gear rack
Kmuffin posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi all. I'm currently making a moc with some small sets. But I wanted to make some extended outriggers but the parts in the sets I'm using don't have 1x13 gear racks and the 1x7 gear racks are already used (which are anyways a bit too short). Is there an good way of making extendable outriggers without a gear rack? -
Hi guys, I'd like to create a set, a small one, for a series I invented, that is some kind of saga, now this one I thinked should be one of the smallest in the series, a set priced 14,99€ and is inspired by a real gate. In the file you will find some reference photos and a prototype, made by myself, but that lacks a lot. I tried to make it, and I did my best, but it's not already what I'm looking for. Now what I ask you guys is to think as a real lego designer, so take this model and review it, change whatever you want or even start it again from the beginning, to make it looks like a real set, but the most important is: make it cool! This is not a contest, just an help I ask you. This idea could be interesting because everyone can make a different thing, that is related with his idea of lego set. Sorry for bad english. https://www.dropbox.com/s/yoetg94jv2arrbc/set.to.rar?dl=0 hope you enjoy this

My first attempt at an Un-Specific Pacific (USP) was met with only partial success, it wasn't very fast or powerfull, it looked too toylike for my tastes and it was mechanically unreliable. The chassis and drive was basically a stretched and bastardised EN chassis and it was clearly not fit for purpose. I've been planning a v2 for a long time now, and have finally started. The XL motor is getting replaced with 2 L motors and the gearing has been simplified significantly. This has vastly improved the speed and (i think) the power to the wheels, but the has come at the expence of grip, causing not only significant wheel spin but also it to routinely pop the con rod from the leading wheels. It's powered through the centre (flangless) wheels, which drive the outer (flanged) wheels via the con rod. I did this in an effort to maximize the weight and power applied to the two flanged wheels, but that's looking like a dead end right now. Any ideas, suggestions or tips would be greatly received. Current build (tender will probably stay largely the same as the original build, although I'm toying with seeing if those little baring will make the standard Lego train wheel assembly a little less draggy). And v1 (before all the bits had arrived). Once I have it mechanically where I want it, I want to give it a smaller boiler and a more tapered cab roof, plus any and all grebelings I can think of.

I've been researching miltary moc's for months now, and finally have a couple of vehicles built and I was wondering how other people would start. I have a decent sized collection and was hoping to do the moc in a grayscale (white, gray, black). I was wondering if you had any advice for moc's of any size. Thanks- kartracer21

92908 Portal Axle - how does it work?
Richard Dower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I actually genuinely dont get what these do?.....it seems you can add gears to this, what is the point of that? I am not a steering and geometry expert or a car person, are these designed to add some interesting new techniques and building options? http://www.bricklink.com/catalogItemIn.asp?P=92908&in=S -
[HELP] Controlling 3 driving rings at once
TheMindGarage posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'm building a 6-speed sequential gearbox for use in a future MOC and I've come across an issue. Basically, I need to control three driving rings with a single input, but I can't figure out how to do it. I'm familiar with the standard method of controlling two rings by using eccentric mechanisms 90 degrees out of phase, but this doesn't work with 3. I need six positions that can be selected with a single axle. I don't need a paddle-shifter - I can do that bit myself. The positions must be in order like this: [The three changeover catches are in a line, F means flipped forwards, R means flipped backwards, O means in the middle/neutral] FOO ROO OFO ORO OOF OOR This is all to do with the way the gears are arranged (I needed the ratios to be close; difference between each gear is around 1.3x). I can't change this. The crucial thing is that the mechanism must be compact. I can't give exact dimensions, but I'm quite pushed for space in this MOC. Thanks in advance for any help! -
9398 into 41999?
Richard Dower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I have been thinking about trying to build 41999, i have 9398....to save money on PF parts i would like to use the stuff in 9398. The V2 IR was very easy to remove, just two pins....but without taking apart 9398 or removing a tons of parts....is there any easy way to get out the servo motor or the L motors without too much hassle? Or is it a nightmare job that would require a big rebuild? -
Hello everyone, I am fairly new to this forum and noticed that there are many "guilds" that run the place. I was wondering if this forum is used to support the worlds and story lines that have been set before me, or if it is encouraged to bring in original story lines. Excuse my noobery, -Deme

I've recently emerged from my dark ages, only to be greeted by my entire collection dismantled inside of a large bin. Because I want to finally be able to utilize all of my resources when building, I've been attempting to organize my collection. However, I don't want to end up completely organizing my collection, only to get lazy and end up undoing all of my work. So, does anyone have a method of organization that would allow me to find what I need fairly easily, but not take me days to accomplish?

Hi all, I am rebuilding all my sets to see if they are complete. Today i rebuild set 357 firestation. I do this with the help of bricklink to find all the correct pieces. Bricklink stated that there are 4 4-long en 1-wide bricks with a legoland engraving in the set. 1 in white and 3 in red. I know where the white one belongs in the set. But where do the red ones go? I can't figure it out.

41999 parts in 42064
Richard Dower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
i have been looking over the parts list for 41999 and it has some of the rarest and most exclusive parts, notably the Dark Blue and Metallic Silver parts. i was looking at 42064 and noticed this search ship features quite a few of those rare parts, can anyone double check or spot them for me? do i see the 1x11 and 1x15 liftarms on Drak blue?....i also see the small Dark Blue panels 87080 and 87086, can anoyne see any other liftarms or Technic connectors? as someone who missed out on this set i am interested in trying to find and collect the unique parts to i can build this beautiful set, i have seen it rebuilt in others colours but i think Dark Blur looks the best. http://www.bricklink.com/catalogItemInv.asp?S=41999-1 -
