A subreddit for explaining and demonstrating building tips and techniques. Looking for a way to improve articulation of joints? Need an alternative method for joining bricks in different directions? Need ideas for building gearboxes or engines? This is the place to post ideas and ask questions!

This is not a subreddit to show off completed MOCs or finished creations. The idea behind this subreddit is to demonstrate techniques in building with Lego, give ideas for alternate methods, inspire ideas, and to answer related questions.

If you are stuck in the process of building a MOC and looking for ideas, this is the place to ask questions.

If you have found some interesting techniques for building, this is the place to explain them.

Explanations with pictures for how Lego mechanisms work are always welcome!!

Creating a bend help please

Hi everyone, I am trying to create a stable slight bend in my lego design, that will be able to have flat tile on the outside of the bend. I have attached a couple of pics of the closest examples of the bend I am trying to achieve. The 2nd pic of the lightsabers, is also an example of what I mean with the flat tiles on the outside of the bend. Thank you in advance for your help.

Techniques for adding roof shingles to Monster Fighters Hanted House (10228)?

I recently ordered this beautiful old set, 10228 Monster Fighters Hanted House, which is en route:

The interior could use some more love, but that's easy enough (technically speaking).

Other than that, there's just one thing that I think it's really lacking: Detailed shingling on the roof!

A lot of recent sets have really made themselves stand out as truly beautiful with the roof shingling.

Examples:

bookshop

blacksmith

rivendell

The bookshop roof is especially lovely imo, and includes dormer windows like those on the Haunted House. But I'm really open to any techniques that might get similar affect.

At the more basic end, we mostly just have some plates facing outward on the roofs so that some loose tiles can be attached:

Wednesday

DnD

Suggested techniques?

I think if I can just affix plates facing outward on the roof, then I can decorate them with shingles however I see fit. But there are two complexities that come immediately to mind:

  1. Figuring out how to fit plates together flush while also covering the original roof shape
  2. Figuring out how to attach them with hopefully minimal remodeling of the interior

I'm going to see what I can come up with when the set arrives, but if anybody has advice or can point me to a relevant blog post or anything, it'd be greatly appreciated!

EDIT: Looking at Bookshop's instructions, I see that it is using clips and a bunch of stacked plates that just fold down vertically from the top and rest there, not fixed at the bottom or sides:

That should be easy enough for the flat faces of the roof, but the corners will be more complicated. Looking at Wednesday Addams gives some more insight about how things can be attached in the turret/corners:

But it seems like it's going to be black magic figuring out which wedge plates can fit together to produce a valid roof 😰

Build Idea

I have myself a customized Lego Creator Expert 10265 1967 Ford Mustang GT Fastback, and one of the custom things I gave to it was a tow hitch

And some time after that I thought "What if I made a trailer that can fit a Lego car like the Mustang on it?", and when the Lego Icons 10304 Chevrolet Camaro Z28 got released, I thought "What if I bought it and built a trailer for the Mustang to tow the Chevy around?"

So my question is, what bricks would I need to build a transport trailer for the 10304 Z28? (Please send the brick ID numbers)

How do I design a small HEPA filter and flush pivoting window

My wife wants me to make an MOC biosafety cabinet for herself and some of her friends/work colleagues, and I've run into two small issues.

  1. The first issue is a HEPA filter on the top of the inside of the cabinet. The only way I can think of doing it is with a grill plate and using an inverted flat plate (studs on both sides, 1 standard thickness or less thick). Does LEGO make inverting flat plates? If not, any ideas on how to design a HEPA filter on the bottom part of a LEGO plate? (It looks like a fine mesh irl.)
  2. The second issue is a window. I'm looking for a solution over 2x6, but at most 3x6 in size (landscape). I've found via bricklink that LEGO appears to make a 3x6 clear window and that could work. However, I would like the option to have the window pivot open roughly 3/4 or higher from the top of the window. Alternatively, it could slide up - which is what these cabinets have irl, but sliding seems practically impossible on a small build, unless there's a specific piece that does this. I tried a window, but my wife didn't like the colored rim on the bottom and I'm unsure if LEGO makes 3x6 (landscape) windows anyway. Is there a way to make a window that can pivot out or up that is relatively flush with the exterior of the cabinet? I don't want to have the window taking up one stud width on the exterior of the cabinet, nor do I want the top part of the window to have a large gap.
  3. While I'm asking, does LEGO make a normal scientist minifigure? The ones I've found are silly. I was hoping for something like the minifigures for city space.

Here's an image of it's design so far. It's not finished: it's primarily for helping me see the sizing.

Thank you for any input.

Small gaps between tiles?

I’m getting into solo building so I wanted to start with something simple. I chose to do the Hexahedron from the game Fez, but I’m having trouble. I can’t think of a way to leave a gap between the shapes on the cube’s faces as shown in the picture. The only solution I could think of is to make the gaps 1 stud in width, but that would substantially enlarge the build, which I’m not looking for.

Most creative use of a part

What is the most creative use of a piece that you have seen? The most-off-the -wall use that made you second guess yourself as a builder?

I want to recreate my house using LEGO

Hey everyone,

I could use some advice. I want to make a LEGO model of my house and need to figure out how to recreate it using the blueprints. Any tips on how to go about this?

Thank you all in advance.

Hidden rooms/ secret passages

I'm looking to build secret passages/hidden treasure rooms. My kids love finding secrets and Easter eggs Like that in buildings and bases. Even ships, they live space ships. How do I hide these things where it's not obvious or bulky? I have limited space for these things.

Is there a Lego sponge like material?

For the EV3 and spike series, there’s an ultrasonic sensor that uses sound to see distance from an object. In my class I’ve used sponges and sound proofing to demonstrate how the sound waves interact with the environment to my students. I was wondering if there is a LEGO piece that would have a similar property.

How to I get this arch to meet back up to the plate studs?

How do I get the hinge arch to meet back up to studs on a regular grid? What degree angles should I use? Alternatively I can also use brackets to connect the hinge arch but that wasn't working either.

Rotating parallel adjacent bars

https://preview.redd.it/x5fs438cs05d1.png?width=1540&format=png&auto=webp&s=11803cd853ebfdb415c7a4325b85a539e5613e5c

I'm really struggling to find a way to rotate these bars adjacent to each other like this. I really wish LEGO had a positive stud version of 2555 it would literally solve all my problems.

If anyone knows of some obscure piece or technique I'd love to hear it. The bars have to be in close proximity, almost touching so I can't use 48729 + 11090 because the bars would be way too far apart. They have to be able to rotate 360° so I can't use 2555 + 61252/4081.
