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 !shitreactionariessay@lemmygrad.ml
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

I've used waterjet, CNC, and EDM parts. The waterjets typically give me ~100 micron accuracy, CNC ~20 micron and EDM ~10 micron.
"All parts of the vehicle"
Yeah just cut out the body in waterjet, how hard can it be?
Doesn't temperature affect precision within that range? Like when the parts cool down, they'll be unprecise.
At my old shop they gave the job of running the EDM to the old dude who regularly fell asleep during his shift.
What I'm saying is that those machines are slow as hell.
For years, the production rate of cybertruck was 0/year.
Musk wants us to use EDM to manufacture all the parts, so we're committed to producing a single cybertruck a year
