How do I build a truss 5mx3mx3m?
What type of truss should you have, framework, trusswork, Swedish, etc., there is a plethora of different constructions.
If you absolutely want to make them yourself, buy the truss book as it includes a design and dimensioning program for timber and nail plates.
Otherwise, if you have time to wait, it is both cheaper and easier to buy prefabricated trusses... I know from experience as I am building five framework trusses myself that will contain about 3000 anchor nails.
It's the first and only time I'm building such trusses myself!!

Thanks c_vette for the answer! I simply can't afford to buy everything ready-made. There are probably parts that I can manage myself. I meant a saddle roof with a slope of 27 degrees. I wanted to know how ONE saddle roof is built and use it as a template for the rest. I need 10 of the same!
One trick is to look at construction descriptions from, for example, svensk trä and finja betong. The latter has some constructions where it's intended for you to build walls with their products, but they also have drawings for roof solutions, incl. trusses in various widths.
Thank you mats_o for the answer! Good tips!
I borrowed the truss book from the library. The calculations and drawings were attached to the building permit application.
Rough estimate on nailing yourself (Byggmax prices):
Span 8.4m, 14°
Material cost (approx. 20lm 45x195 and approx. 8lm 45x95 around 575 SEK each
Nail plates about 10 per side, i.e., total about 20 per truss, average price 10 SEK each approx. 200 SEK
Anchor nails, can't be bothered to count, guesstimate 400 per truss = 80 SEK
Total: 855 SEK each - Say 1000 SEK each to be on the safe side.
What does an equivalent prefab truss with shipping cost?
I recall a previous rough estimate showed about half the price when nailing yourself.
Once the first one is done, the rest go pretty quickly.
If there are 2 of you, you can make a truss in an hour. One cuts and one nails... and there are always curious onlookers who happily hammer in a few nails.
Sure, there are many nails, and it can be felt in your arm, but anchor nails go very quickly once you get the hang of it
it's not quite like hammering five-inch.

Investigated the price situation (Norrland): 1500kr each, plus 2000kr shipping. Then decided to buy dismantled lumber cheap (very good condition, from a military building). It included sills, floor beams, wall studs, and roof truss wood. I have previously built a wood shed and an outhouse. I have also looked at finished summer cottages to learn more. So I'm a novice, but building roof trusses can't be that hard. I'm happy to nail as many nails as needed. I asked for specific advice. When placing the two beams, which will become rafters, on top of each other and cutting one end at an angle, what determines how angled the cut should be? Is it possible to nail the support beam to the wall studs and then nail the rafters to the support beam? Or must the entire triangle be nailed together first and then hoisted/pulled up to be nailed to the wall studs? I think everyone has a point in their reasoning, but as I mentioned, I can't afford it, and besides, I think it would be fun to look at the cottage and say: It turned out well!
I don't know what you mean by 5x3x3 meters... but the forest industries have a description of the so-called "enkelstugan."

There you'll find trusses with spans of 5.2 meters and 6 meters, and you can choose the snow zone. However, the angle is a bit different, just over 30 degrees.
Maybe that can help.
I myself think, just like many others here, that trusses are one of the most sensible things to outsource, at least if the spans are getting longer and/or the models more complicated.
But OK, if it's up to 6 meters in span and a very simple construction, then you can probably consider making them yourself.
