Help with old topic regarding engineered joint on joist

[diy_er]

Hi, some time ago i saw a topic showing good pictures of a an engineered joint connecting the new floor joist to the roof rafter at the eaves area, thus forming a truss when fitting a new loft floor.

I wish to put new floor in loft to high standard and liked what i saw can someone remember this post and link me to it please.

Cheers , brilliant site.
