I turned a test bar the other day. 2 thou difference bigger at tailstock end.
Just used my Mitutoyo digital indicator after making a holder for it.
At first I was very pleased with the result.
Zeroed it at the tailstock end.
It shows a 2 thou difference by the chuck.
The I realised it should show a 1 thou difference. Or should it?
Why the discrepancy?
