Nissen huts are one subject I have done quite a bit of research on. I bought the book about Quonset huts a few years ago, but it does not have enough info on dimensions. I had searched online but found nothing, so it was encouraging to find some good drawings online this time.
The classic Nissen hut is 16ft wide, but was also done in 24ft and 30ft widths. Interestingly the curved panels for the 16ft one are actually bigger than the ones for 24ft. A school had some Nissen huts and had published info on sizes. Unfortunately they did not have any of the biggest ones, so no details. I wouls assume they were more similar to the 24ft ones.
The panels on the 16ft ones are 10ft 6in long, and each section of building(framework) is 6ft. Based on normal corrugated iron being in pieces about 30in plus overlay, this would result in odd figure for section, so maybe the panels ere either wider or narrower.
My initial design in 3 sections is full 6ft wide, and overall in 1.12th scale, far too big to print(it seemed to stick on upload), so I would panels separately. Need to do some tests on framework.
In 1/32 scale first test on complete section including framework uploaded OK, so hopefully OK for 1/24 as well. If not, then it will be the curved pieces which will be printed(they are the difficult piece to make). Would like to know actual widths so can produce sections to make un-built huts etc.
Most of the kits I have seen only reproduce outside, not inside, unless you opt for one of the fancy etched metal kits, but not sure if they are available in bigger scales.
One thing that had not dawned on me was that this year the Nissen hut is 100 years old, although it is partly based on older designs. The patents date from 1916.
That website is new to me. odd I did not find it. Some interesting photos, and one showing construction of an even bigger hut(40ft wide). Looking at one photo and I estimate each piece is 2ft wide plus overlap. Will have to count waves to check(8 times 3in is 24in so that must be it- so with overlap 27 or 30in).
