After fighting the setup half a day, I finally realized a tiny bit of floor pan was hanging up one of the rails, pushing it out of position. This threw everything off 1/2” at the rear.
I stripped off the clamps and rails and trimmed.it.one.more.time. Yeeesh!
Finally, I was able to make everything come out straight and square. Enough.
But not before I re-rigged my trammel supports for more travel. I couldn’t quite get the long sides measured.
The frame measures square and straight now within 1/16” everywhere, by my measurements. Considering my equipment, that means it’s absolutely no worse off than 1/8” in 120” on the thrust vector. That’s about 1/960 or a thrust angle of no more 0.08° from center.
Plus the suspension is all adjustable for way more than that.
That final setup and adjustments took all of my remaining will to fight on, until tomorrow.
I’m praying for still air, because the welding starts then.
Also, be careful if you ship a Chinese car to America…
