I'm not sure that mechanical precision is that important. Everything on a view camera is infinitely adjustable so as long as it doesn't move between composing the shot and pressing the shutter it will be fine.

You don't want anything warping though as this can affect the correct seating of lens boards, the ground glass back and the focussing rack, possibly leading to light leaks and difficult focussing.

Judging by the number of wooden cameras in existence, I don't think it's as much of a problem as you are imagining it to be.
