Truss:
- 2x4 lumber (3.5x1.5" in the USA).
- 7/16" oriented strand board (OSB) plates
- Plates are 7x16", and the small squares are 7x7" typical
- 22 inch high
- Vertical after every 2 diagonals
- Total diagonal length of members from left to righ - 22"
- Verticals are 15" high
- Our trusses are 32 feet long
Learnings:
- If I were to do it again, I would just do the top and bottom parallels, and cover with 24" OSB from 4x8' sheets, on both sides. This is DIY 'engineered lumber'. I call it the wood-OSB sandwich.
- Total cost of truss shown is about $50 for 32' including nails for nail gun
- Total cost for new version is about $40 for the same, and I guess that the strength is much higher for the simple wood-OSB sandwich. Just stagger the joints properly. The weak point in the former is the large number of small pieces. The more monolithic, the better.
