Hello everyone.
I can nail two planks together and make something, so far so good. But when it comes to more complicated matters, I need help.
So: I'm building a porch for the house. About 2.5 x 3 meters, so it's not a big build and no large spans on the roof. But I don't know how to handle the construction of the roof trusses. See attached image.
If I just overlap the pieces and pull them together, the top plate will end up in the air on the other end.
If I cut the ends of the trusses at an angle, the top plate will be easy to handle, but I'll have a much trickier time with the assembly of the truss.
What should I do??

Saw at an angle and join with nail plates. Otherwise, you can order ready-made roof trusses so you don't have to think about it, for example here http://www.takstolsfabriken.se

It IS tricky to make roof trusses. Just bring out the try square.

"Hammarband" - it is not the bottom part of the roof truss, it's the top part of the wall.

Andersmc is absolutely right, the bottom part of a truss is called the underram, the upper parts are called the overram, and the pieces in between are usually called struts.
 
One can't know everything ;-/
But diagonal cutting is, as I understand it, the recommended option! Let's see if the weather allows enough outdoor time tomorrow to try this.
Downpour and building is not a great combination!!

Well, that's a good thing, otherwise forums like this wouldn't be needed :) But if you are unsure, it's better to ask and learn that way or find it out by yourself.

I agree with you, I also cursed the Swedish summer today, the one that's supposed to be so nice, bah. Get the things out, you just start, and then comes a damn shower, and you have to quickly get everything in again, and that's how it goes. Just have to grit your teeth.
 
Prefabricated trusses are clearly the best.

The issue with four???? There's no problem with that distance, the timber can withstand the twisting that occurs with those timber countries.
