Tractor boom is a practical/good idea!
Homemade trusses!
Terrible idea..... using SMALL squares of chip board as truss plates!
Likely would NOT meet code anywhere!
In a North Idaho snow load environment, those "trusses" are a very bad idea!
Design may(?) be OK, but connectors are UNSAFE!
Perhaps..... OK in Tucson?
My house has been picked over by many a person, most just do it in person and not from 3000 miles away.
Well smarty pants, you don't know as much as you think you know.
My house is 100% custom built to be super efficient, super strong, and super high tech.
If i told you what it cost me to build and what the house appraised out at, and what it would sell for, it would give you a heart attack!
Yes the trusses are hand made, as is the rest of my house, but they are 120 PSI 2x6 top and bottom cord engineered trusses.
I have the stamped engineered blueprints.
Laser measured deflection was less than 1/4" across 40 feet clear span with 6 feet of wet snow on them.
120 psi is twice what is required for our heavy snow load.
Oh and FYI, I also build and remodeled quite a few homes in Phoenix, Scotsdale, Carefree, Cave Creek, and Paradise Valley, AZ and their trusses can have more load than snow load specs, because of heavy roofing coverings like stone, tile and slate.
They are also built with better lumber than what a truss manufacturer would use.
All tamarack / larch that is grade stamped Select GOLD or also know as Select structural (best of the best) .
And yes the tie plates are OSB, that are construction adhesive, 2 1/2" stainless stapled, and ring shank nailed.
There are a ton of articles and engineering studies done on this type of truss manufacturing
They do not fail over time, or under extreme weight shifts.
They also do not fail over time like small stamped metal plates.
