It's the dunk tank.
This is where you come to post big-brained hot takes by chuds, libs, or even fellow leftists, and tear them to itty-bitty pieces with precision dunkstrikes.
Rule 1: All posts must include links to the subject matter, and no identifying information should be redacted.
Rule 2: If your source is a reactionary website, please use archive.is instead of linking directly.
Rule 3: No sectarianism.
Rule 4: TERF/SWERFs Not Welcome
Rule 5: No ableism of any kind (that includes stuff like libt*rd)
Rule 6: Do not post fellow hexbears.
Rule 7: Do not individually target other instances' admins or moderators.
Rule 8: The subject of a post cannot be low hanging fruit, that is comments/posts made by a private person that have low amount of upvotes/likes/views. Comments/Posts made on other instances that are accessible from hexbear are an exception to this. Posts that do not meet this requirement can be posted to [email protected]
Rule 9: if you post ironic rage bait im going to make a personal visit to your house to make sure you never make this mistake again

What the fuck. Plastic will lose that .0002" tolerance if somebody farts in the same room (especially .0002 over 12 inches!). How do you even measure the location of a hole that size? If you're trying to nail the position down to .0002 what the fuck is the cylindricity supposed to be? Atomically perfect?
I’m over here thinking about temperature changes. It will be precise within 0.0002” at the ambient temperature on whatever Wednesday at whatever time
Going by a thermal expansion calculator, if the part is steel, then a temp increase by only 20F will cause the length to increase by 0.0048”. Idk what the coefficient of expansion is for plastic, but it also has one and it’s probably going to result in variations larger than 0.0002”
