Does the jaw drawing include the blank being held?
blank fits, jaws don't?

Why is the door missing from a clearance argument?
12 pointsAaron, yes, blank is in it. Gabriel, old machine drawing. Door got treated as a later detail. I've asked our setter to mark its working opening on the same view.
2 pointsDo the cheap drawing check, certainly. But do not spend days saving a base position nobody has actually committed to. I walked away from a layout that consumed the changeover route whichever way we turned it.
16 pointsIf there is another approach available, Anil, what makes this one attractive? Shorter travel, or does the setter need the other side? That would change how much effort I would put into it.
21 pointsSetter works from the other side. I'm trying to keep that access. Isabel, agreed about not falling in love with a dot on the floor. This dot is currently only pencil.
6 pointsCan the jaw backs be shorter?
8 pointsThat is one for the toolmaker, Aaron. Shortening a drawn outline is very cheap until someone has to make it grip properly.
10 pointsMeant ask them, not cut them ourselves.
13 pointsFair enough. A revised jaw could help, but I would want them to check release as well. A part can be easy to carry in and awkward to leave behind.
6 pointsDoor outline is on the drawing now. Straight entry is blocked by the jaw backs; angled entry gets those past but puts the rear fitting at the door edge. So there are two snags, not one.
5 pointsDoes either approach leave room for the opened jaws?
7 pointsImran's release point matters here. Anil, have you been given just the closed-tool picture?
11 pointsOnly closed. Toolmaker sent the open outline after I asked. That also interferes at the angled position. Thanks, Imran, that would have been an expensive omission.
12 pointsSo that angle is out?
16 pointsWith this tool, yes.
17 pointsWould the setter accept a different fixture orientation, Anil, or would that just move the obstruction into their way? I do not know your machine access well enough to guess.
6 pointsMoving the fixture can also change their loading job. Do not offer it as a painless fix before they have seen it.
16 pointsThe setter has looked at the alternative orientation and doesn't want it. Harder to clean the pocket and inspect the seat. We have binned the angled approach and asked the toolmaker whether a different tool concept is worth pursuing.
20 pointsAt least the door finally got a vote.
