Our FR5 planning sheet lists how far each hand-loaded blank sticks out but not how long the blank is, and somehow the conclusion says inconsistent seating, which seems a remarkable amount of certainty from half a measurement.
Why are we blaming loading when nobody measured the spacer blanks?

Pair overall blank length with exposed length for each identified sample. Also agree the chuck reference with the setter. Otherwise two people can make equally careful measurements of different things.

And check the end that meets the stop, not just the end you can see.

Our burr was on that hidden end. Worth checking, not assuming it's yours.

Have the setter define the intended seating and manual comparison method before taking another set of readings, while automatic loading remains outside this check.

Setter and inspection agreed the reference and marked each blank, and the first paired measurements explain most of the spread through actual stock length, which the spreadsheet had politely ignored

What does most leave over, Robin? One awkward blank or variation across the lot?

Were any individual blanks repeated, so you can distinguish differences between blanks from differences in seating the same one?

Repeat the identified awkward one and ordinary blanks through that agreed check, rather than taking another handful and losing the links again

One blank gives a larger exposed reading on some repeats while ordinary ones are consistent, and the setter says that one feels different at the stop, so it is retained separately with its readings

Did inspection find a damaged end on that one?

A raised edge on the stop end, yes, but we have not assumed it caused every longer reading just because it looks guilty

Sensible. Mine was a burr; yours still needs the contact checked.

Keep the blank's original condition documented and let the setter and inspection assess how that edge meets the intended stop, rather than changing the loading allowance around it.

They confirmed the raised edge makes that blank catch before full seating; ordinary conforming blanks remained repeatable, so the estimate now separates normal length variation from this rejected blank's seating fault

Useful result. Has the corrected allowance reached the FR5 proposal itself, or is the old figure still living in the supplier's copy?
