    Quonset hut under construction. N scale.

    I am deciding whether the ridges for the curved part should be longitudinal or transverse. I have prototype pictures of both types; I presume that is because of the prefab nature of the building. It sure seems it would be easier to make them longitudinal.

    Reference the quonset hut corrugation direction.

    I believe the "correct" answer is that the ridges should be transverse, for drainage. Otherwise at the top of the structure you get puddling, and that's a sure fire recipe for leaks. Clearly you need curved panels to do it this way, so as you say there's prototype for each.

    Most common is front to back on a building like yours. 1st it's hard to get the sheets to bend the other way, 2nd they're overlapped so they don't leak. Usually theres a ridge cap with vents, so puddles aren't an issue. Mostly #1, trust me, it's hard to do it the other way and get it to look right (on the prototype:tb-biggrin:).

    Quonset Huts!!!

    That is all these are!!! Old Style, Quick Build, Post WWII Military buildings turned Commercial.

    I've seen lots of these in my life, most notibly the one's I slept in while serving my time in South Korea. Seen videos on how to assemble them and such.

    These things were made one way. No ridge cap needed as the corrugation does not run across the hut but from the ground on one side to the ground on the other.

    I don't know how proto-typical you want to get, but to do it right will be the more difficult of choices.

    So far it is a great looking building!!!!

    I've never built a commercially available one, how do they bend the sheets without creases?

    Quonset Hut

    Sheets of corrugation are pre-bent and drilled at the factory. They come ready to assemble in the field. The sheets are alot thicker than regular corrugated sheeting used on roofs.

    Googled this mfr of steel buildings. Now then what size structure were you looking for??
    They have some excellent pictures & prices both inside & out!

    A classic military building has the arch design. Newer versions can have a straight side panel. The corrugations go sideways, not lengthwise.

    The main advantage appears to be the lack of any interior posts, so the whole space can be used for whatever. The disadvantage is the lack of any side windows. Not sure if they could be "insulated".

    Walthers did a Nscale version with sidewalls. Have fun with your project!.

    Quonset Hut

    I'm just getting back to read this thread after a few weeks. Thanks for all the responses and ideas on the corrugations. I think I will make the corrugarions run across the building. The picture I have like that appears to be a "standard" building as it is very large and roomy. The smaller building seems to have an odd shape.

    The smaller building has curved "windows" cut right in the side. I don't know how they braced it or kept the rain out. OTOH, it doesn't rain much in San Antonio, so...

    I thought there was another thread on this? With pictures.

    [edit] Heck I'll add the pictures:
    "Standard" hut, very large, probably 30 feet at the top.

    Smaller structure. Very long compared to most Quonset huts.
    [edit #2] The photo above is a Quonset hut with longitudinal panels; this is rare as far as I can tell. There is a row of transverse panels across the top.

    I am in the process of building a quonset hut for my layout. I can find several references to quonset huts all through TrainBoard, but not a lot of information in one thread. Please add your pictures or ideas of both prototype and models to this thread.

    I'll start with my pictures. But first, I will copy some other good posts from another thread. They will appear above this post and may appear incongruous to the thread, but never fear, it will all work out. I hope. Here goes.

    [edit] It worked to get the thread started. All the posts above this one were copied. I know I have seen other quonset hut models and photos on TB, so you guys please post them up. Thanks.

    Two more photos of the large structure.

    Close up of roof/end interface:

    Back of building. The bottom of these windows are six to seven feet above the ground.

    Wow! A double. I don't think I have ever seen one of those before. Probably "kit bashed" after the war.

    Rix Products also makes modernized Quonset huts.

    Here are prices from their 2008 catalog.
    628-0410 Quonset Hut Prefab Quonset Hut 24 X 33 X 12 scale feet (HO)............$11.99
    628-0710 Quonset Hut Prefab Quonset Hut 24 X 38 X 12 scale feet.(N)...............$11.99

    Below are images of an HO scale Rix quonset hut:

    Each side of the Quonset is different. On side has a large garage door and the other side has a walk in door and window. These are photos of an unpainted kit so the glue marks will still be visible. The detail is excellent and it makes a very nice kit even though it is a little on the small side. I wish the edges of the roof panel were a little less thick but to do that it would have to be brass or some other metal and it would list at a lot more than $11.99.

    To give an impression of the size, I have included, in the photo, a 1972 Chevy pickup and a 1977 Firebird

    That would be my guess. Good luck with your project!

    Here is my painted Quonset hut. I did the panels longitudinal, didn't like them, and changed them to transverse. But, I see form the pictures above that there are some Quonset huts with longitudinal panels. It appears that longitudinal panels are rare. I am not sure that the one I saw with longitudinal panels was original; it was very small.



    Dee Das: The other two huts are the Rix products you suggested. Very nice product and thanks for the suggestion.

    I built one from prototype photos. It has the ribs vertical on the sides.

    Looks good, Russell. :thumbs_up:

    Just thinking...you could cut a PVC pipe lengthwise and have a good shape. I might use a table saw to get a clean and, more importantly, an even cut.
