This quote above is probably good advice for someone starting a chassis, depending on your backround tolerances are different to people, when i was plating +-2.5mm was acceptable on most jobs, but when i done a spell in a machine shop +-0.5mm was huge on some jobs

On a chassis everyone should be aiming for zero tolerance i know in the real world this is almost impossible especially when its welded but we should strive to be as exact as we can.
