I'm going to a competition at the end of the month and this is a drawing from last year's test that I have to practice. The bottom edge of the cored hole just before the fillet is supposed to be 1.8 but the best I seem to be able to get is 1.79.

Hello,
I may not be understanding your issue correctly, but this edge of the core is 1.80:
As is indicated on your drawing.
It's a casting with draft, so further into this recess, the diameter will be less than 1.80.
Since it's a drafted core with radiused edge, I'd interpret the drawing to mean 1.80 at the virtual sharp.
Which is what I measure.
Like I typed, I may not be getting the picture.
Cheers,
Kevin
Thank you! I suppose I hadn't thought about the virtual sharp...
You're welcome and good luck with the competition.
Cheers,
Kevin
