PS: Hey Mr. Markus - any more thoughts you have that you could like maybe share with me BEFOREHAND?

You can't depend on roof panels to maintain the structural integrity of your roof framing.
If you wanted a cathedral ceiling, you should have put in a properly-sized ridge beam. The roof would not have sagged then.
I would recommend putting in some diagonals to prevent racking in your roof structure, too.

By racking do you mean bending in the horizontal plane into a parallogram?

Nice work though. You have a stunning building and it should be a real class setup when you are all done.

But it immediately came to mind; 1 track with -V- grooved wheels, and the other side a flat-track. Can be quite accomodating with any variance in width or flex.
Welding ain't as precise as most dudes think. I used to straighten car axles by placing welds in strategic spots after preheating, etc with 180k psi tensile welding rods---
bla,bla.... Runouts in the .00x", etc.
Maybe next time?
PS one question- did you chaulk-line the tracks to see if the welds pulled the tracks 'concave' a bit??? I find it a bit hard to fathom a triangle 'truss' flexing that badly to bind if everything is straight.....? Just an idea.

Each roof slope is a rectangle now. There is nothing to prevent that from distorting into a parallelogram in the future. Corner braces or large diagonals will stop that distortion.
Large diagonals would be the strongest solution at this point.
Run two on a side, each from an outside corner to the midpoint of the opposing line of the roof.
Since one diagonal will always be in tension, they don't have to be that beefy.

You can see one of the remaining details I need to take care of, my neighbor two houses over with a yard light shining on the building. She seems agreeable to my paying for a light shield.
Next to do: side panels on roof, install cable system to roll the roof, finish the door and apply weatherstripping. Once I know this thing is weather-resistant (but aiming for weather-proof), I'll hook up the juice, run the wiring, and build the warm room, then I'll be ready to move in.

It's about 70 feet down the hill from my house. Gonna try a 4G hot spot first. If that doesn't work, then I can mount a pair of wireless antennas. Hate to dig another trench for CAT-5.
