Our hand-loaded spacer blanks have different stickout readings. Nothing else measured. What separates blank length from seating before the planned FR5 loading study? Automatic loading is not authorised.
Why are we judging seating from exposed length alone?

Were those readings repeated loads of one identified blank or readings from several different blanks?
14分Several blanks, with no individual identities on the sheet.
11分Then that sheet cannot give you loading repeatability. It mixes whatever varies between the blanks with whatever varies when they are seated. Keep it as an observation that exposed lengths differed.
23分I'd have the setter show the measuring face and intended seat to whoever collects the next readings. Two people can both write stickout while using different references, and the spreadsheet will politely accept both.
9分David, would a marked sketch beside the sheet be enough for that reference?

A sketch helps after they agree what it represents, Louis. I'd still ask each person to show the reading on the actual arrangement; the drawing cannot reveal that they understood it differently.
6分Dinesh, can you measure the overall length of each identified blank before the agreed manual loading checks?
10分Yes. Quality can include blank length and repeated manual seating readings in the new sheet.
19分I would also keep the blank's end condition visible in the inspection notes. Length alone isn't the complete physical explanation if the relevant contact surface differs, though nobody has established a contact defect here.

Would subtracting blank length from stickout isolate seating, or am I oversimplifying that?
15分Depends on the defined references. I wouldn't subtract columns before agreeing what each measures.
9分Which end and fixture reference does the current stickout measurement actually use?
6分That isn't specified on the old sheet either. I'll leave the calculated column out for now.
20分Good reason to define the method before designing the spreadsheet. The useful question is how the blank sits against the intended reference, not whether we can make two available columns cancel neatly.
11分David, I'd still record the raw lengths even if the derived measure waits. Otherwise the next review discovers that somebody retained only the calculated answer and threw away the evidence behind it.

Agreed, Will. I was objecting to an undefined calculation, not the raw measurements; keep those with the blank identities.
20分Will the repeated loads be distinguishable from repeat readings without unloading?
21分I'll give those separate entries. Thanks Nadia; repeat reading and repeat loading were sharing one heading.
22分That distinction matters. Measuring an unchanged setup several times can help you understand the measurement, but it does not show how consistently a blank seats after removal and replacement.
18分Who is agreeing the completed manual measurement method with quality and the setter?
