I don't know of too many boiler designs other then the standard 45 slope boiler and the EN boiler.

And this wedge boiler design. Do you folks have any other ways of making a nice boiler.

I use the boiler from the Lone Ranger train on most of my builds... it works fine for my Roaring Twenties-era (that's the 1920's in case you didn't know) layout.

Depends on what size you want. I use the following SNOT design for my Single Fairlie and Lombard Log Hauler:

Also, pretty sure that the cheese-wedge boiler you posted is the same as the Emerald Night boiler, but with cheese wedges instead of curved slopes.

I use a boiler design close to the EN boiler, but with a smaller diameter.

Also, pretty sure that the cheese-wedge boiler you posted is the same as the Emerald Night boiler, but with cheese wedges instead of curved slopes.

EN's is larger (mostly through extra plates under the curves) and considerably more hollow.

How big a boiler do you need? There's a *lot* of techniques, all with their advantages and disadvantages, but one just because idea may be perfect for one loco doesn't mean it fits at all on another.

Here's another one:

For one of my projects, I needed a boiler with exactly 17 plates diameter. But I'm not quite happy with the use of hinge plates to get a more rounded shape, so I abandoned the project for the moment.

Could you do the top and bottom in the same way as the bottom? Or even use 3-wide slopes?

I'm not looking for anything in particular I thought it might be a help to have a post about most boiler designs we can think of. I just really dislike the EN boiler.... It gives up a lot of potential for detail unlike a cheese wedge boiler.

I don't think this violates any rules, and pretty sure Tony posted these for general use and education, but I used this boiler on a narrow gauge design. e.g. it's small and would fit on an american or narrow gauge early loco. Set of 2 pics:

This allows for a modified plate with clip light to be added to attach a dish to the front of the boiler. All props to Tony!

I really like the EN boiler design...though I have modified it a bit for my builds. I mostly build North American Steam and need something a little more like an oval.

I like this design because I can put a lot of detail on it like the hand rail and walk way and even steps on the side or clip extra pipes along the side and it still looks nice and round.

Exploded view.

Super clever work, all! Love seeing these studies and solutions. Very cool stuff.

For my BR70 I needed a narrow boiler, only 4 studs wide. The obvious choice at that size is macaronis but I still needed to attach sand boxes and stuff at the top.

After trying a number of options I ended up putting tiles around core made of wheels. The tiles are just held in place with (original Lego) rubber bands.

What did you use for the smokebox?

From my untrained eye it looks like one of those submarine propeller hub.... things....

A similar technique was used for the water tank on 10246 Detective's Office, using the old wide technic chain links wrapped around a 24-tooth gear, and the tiles plugged into that.

Yup, absolutely correct:

Very nice use of the submarine propeller hub.

The Dino neck piece can work too. It's tough to get it all to hang together.

In the old days I used castle corner walls similar to this tanker MOC.

There.... I made this using 2 different types of boiler designs for this smaller locomotive. I got this built during a stream on twitch if anyone is interested.

I started a (digital) design of the NBDS 118/119, later known as NS 4500. For this I needed a 4 stud wide boiler as well. I usedthis and this. In addition I used a few of these to connect a dome and pipes.

Macaroni bricks can be used in place of the round brick without holes, but because the round plate doesn't exist in green I can't build a NS version yet.
