Well I did - but I'm not a carpenter.As to the purlinsWhy? Isn't that how they splice rotten joists?
What could be simpler than taking one piece of wood and then cutting a bit out with one saw?
I don't think many SE's would recommend site gluing of structural parts.Why not glue and screw ply triangles to the rafters above purlins?
Seems to me it would be easier, quicker and let the rafter maintain its full depth.
Like this....Not cutting it.
If you have ridge, purlin then wall plate it's a few cuts.
.
The ridge beam is best located beneath the rafter ends.^^. A bit like that but I was more thinking of the purlin/centre of the rafter
I'm confused, as far as I can see you've indeed cut birds mouths at both ends, and there's no purlin to need one. Those horizontal ties near the top is presumably triangulation to keep the steel in place until the gable wall is built, and the cross bracing between the first 3 rafters at the same height to keep everything in line?Like this....
