Examples of what I mean: link
Perhaps to support the roof of your underground base/lair, your asteroid tunnel, or even your spaceship? link link QUESTIONS: Well, have you guys seen this awesome step-by-step? link Any of you done anything similar? Or did you do something else to end up with the same results? If so, what tools and materials did you use? Dan

link His stuff is fantastic. Looks easy but I wonder if I have the patience to make enough of them |

I wish there was a roof section for these: link Dan |

Easy enough to laser up the struts arch shape, might be 'fun' to make sure the holes are accurately placed Unless using plastic or flexible plyboard the curved top would have to sectional. Regards MMG. |

They make this stuff for rain gutters that might be a good start. link |

I just wish those holes weren't in a straight line. If they were, they would be perfect for all that stuff:

What building is the greenhouse roof in the original post from? |
| Claypole | 23 Jun 2014 3:12 p.m. PST |
The Temperate House at Kew Gardens. |

Thanks! That is one of the places in London I still need to see |

FYI, and so you can put a name on it, the more modern examples above are called castellated beams. Typically the holes are in an hexagonal shape, though obviously round is common, as well. Steel is sold by weight per foot and most of the bearing capacity of a steel beam is found in the depth of its section, so the castellated beam is a common solution for long free spans. It's also convenient for passing duct work, plumbing, and electrical conduit through. There's more about castellated beams than you probably ever wanted to know! The beautiful roof structure from the Temperate House is a different animal-some sort of hybrid beam/truss structure. |

ArkieGamer: "the more modern examples above are called castellated beams" Perfect! Now I know what to call them. Thanks, Dan |

Got a bit bored & a load of free time. So something akin to this?
Is 18Wx7cmH, beam is 1cm deep. Regards MMG

Wow! That was quick!!! I think that, if you were to reduce all the dimensions by almost half, they would be suitable for most 15mm projects. From tunnel roof supports, to spaceship bulkhead beams, to roof supports for moderately-sized buildings. Thoughts? Dan |

Can do other sizes as needed, there are minimum sizes I can do, as leaving less than 2mm width uncut between holes makes the MDF somewhat snappy. Regards MMG. |

Think the hex might improve the strength a little. |

There's more about castellated beams than you probably ever wanted to know! Not necessarily… ;->= I always assumed keeping the overall project weight down entered into it. For instance, the beams inside a dig. And, I'd think the circle would be stronger; angles tend to concentrate stresses. Doug |

I guess that many Star Wars illustrators aren't familiar don't see the need to use those beams in the design of space craft:

Check out these Blue Fern Studios "Techno Rings": link I'm sure there's gotta be several useful applications for that product in our gaming world, don't you think? Dan |

A 1/72 model kit for the flying sub….from the old tv show?
Had some perfect beam supports….used them ages ago in a Gorkamorka bmp conversion |
