I work as an estimator in the construction industry, residential home building, as a roof truss estimator. That's the last 20 years or so. I've been in construction-related fields all of my life & will retire next summer. I'm not an engineer, but I do have to deal with a lot of the concepts involved in building trusses.
I started as a cabinet maker for houses, then did a stint in aircraft cabinetry & have build a few rifles, a couple of small wooden boats & other things. I've played with darkroom work & photography, cars a bit & knives.
Here's a job form 2 weeks ago. A church I sent trusses for was built by a guy who didn't read the bracing instructions I provided. Half the trusses came down. No one was killed, fortunately... This is why I can't wait until I can retire, there's a lot of stress at times that goes with the job.
The walls after the trusses came down.

The trusses were 56' long, dual sloping flats.
