Chassis out of square

[will_08]

As said its never going to be perfect, i would like to know what tolerances are actually achievable?

Cutting errors (length & angles) + Parallax errors (from measuring devices) + lack of truth from timber jigs/build base's + heat distortion etc.....................

just got to get as close as you can.

Although big errors at the beginning, start snowballing down the line. Before you know it you'll have to alter loads of tubes to accommodate one error.

Good luck m8
