Thank you sir, this exactly explained why people always say that the bird's mouth must be 1/3 of the width of common rafters. I think of this question for a long long time. You finally gave me the answer

Excellent and informative video. Thank you.

Do you know what codes or textbooks call out where you can start measuring from to get your similar triangles that aren't on a edge of the wood? It doesn't feel intuitive to me at all.

Lovely accent...

[@jimmys511]

Can’t you obtain the length of the rafter by stepping the framing square holding the square on 12 for the run and 7 for the pitch and step it the amount of feet for the run of the building? Instead of figuring out math?

I just need to know what time it is I don't need to know how the watch works

confusing

[@TurboMountTV]

Considering the gaps probably not the best explanation / technique.
