jim: tariq, this should be a light push fit but it didn't feel right when i measured it with the plug gauge.
tariq: the hole must be too small.
jim: No, the size can't be the problem. I've just checked this hole and it measured within tolerance.
tariq: Have you got the drawing?
jim: I've got it over here. It's part number 3785-65D. That's the hole just there.
tariq: Mmmm. Twenty-five millimetres plus or minus nought point nought two one. It's not out of round. have you checked the surface finish?
jim: No, not yet. that could be the problem.
tariq: it looks a bit rough to me. write up the rejection slip and send it back. make a note. the machine shop might be able to rework it.
jim: ok. thanks, tariq.
