The hand-loading sheet lists different stick-out readings but no sample identities. Before our UR5e study goes further, can I learn anything from it without pretending those are repeated checks of one blank?
Then don't. Label the limitation on the sheet and have inspection define a fresh identified comparison. Length, the end against the stop, and the intended seating contacts need attention; exposed length alone mixes those questions together.
I've kept the old sheet with that warning. Inspector is identifying the retained blanks and asking the machinist how each was intended to contact the stop. Automatic loading remains outside this check.
Chuck face to exposed end, confirmed by the person who measured it. Thanks Leah, I've added that description without inventing the missing sample links.
