Which bracket measurement am I meant to give the fixture supplier?

I'm buying an FR5 fixture package. Our bracket sheet gives a clamped angle and a different released angle. Which goes on the enquiry?

What does the current drawing actually require you to inspect, Liam? I'd want that answered before a supplier picks whichever number makes their proposal look easiest.

Released assembly angle. The clamped figure is an old process check.

Send the drawing requirement. Include the old checks as background, clearly labelled.

Our old sheets included checks after a correction operation without saying so. I'd ask whether your released figure was measured before or after any straightening

And do those two figures belong to the same bracket? I got caught reading a batch summary as if it followed one part through the process.

Same serial number. Released reading was before correction, according to the inspector.

I wouldn't send only the finished drawing and hope they price the awkward bit. Tell them the old process needed correction, with the limits of what you know.

That's why I said include the old checks.

Fair, I read past that. Your version covers it.

Who actually did the correction, Liam? The inspector may know when it was measured without knowing what happened on that bench.

A fabricator who's still here. Asked him to join the supplier call.

That helped on ours. The person doing it explained the awkward handling as well as the correction, which was missing from the neat little route description

He says the gusset fit varied. I hadn't even included fit-up photos in the enquiry.

Were the gussets all to the same revision? Not claiming that's the cause, just wondering what varied before welding started.

Revision C throughout that run. Quality is checking the incoming measurements. Thanks, Omar, for the correction question.

Leave room for the supplier to say the incoming condition needs work before fixture design. Buying more restraint because it sounds decisive would worry me here.
