I mean saving after every change is a bit much.

Honestly, @lily70 is right, and that finisher's tip just turned my whole plan upside down too.

Is this just how we deal with old stuff now?

That's a solid save by your buddy's operator, @val_williams. I saw a pad split right down the middle on a 60-ton pick last year, looked fine until the sun hit it just right. We keep a spare set of 4x8 timbers on every site now, just in case. A quick swap before the concrete shows up beats a failed lift test any day. Good ops catching that stuff are worth their weight in gold.

Man, that's the worst. I used to think oil was foolproof too until a similar mess made me switch to wiping varnish for anything that might get wet. @the_anthony, your buddy's bug story is exactly why I'm so paranoid now.
