ick up a 0.020 diameter end mill with 1/4 inch flutes.

You don't have any .020 EDM scraps lying around?


I love this group almost as much as the EAA guys I drive 280 miles every
month to hang out with for an hour and a half. Sure, we could've sent it
out for that. But there isn't any reason that the post can't be blended
into the wall instead of being a separate feature, so I got out my #2
pencil and created rev A., because I know what mounts on the mounting
post and what it needs to be and what it doesn't need to be. And I
didn't sit down in a meeting for two hours with six people to talk about
it. The guy making the part asked me if he could blend it in, I looked
at it, said sure, and it's a done deal.

It's the kind of clumsy engineering that makes things expensive beyond
reasonable comprehension. Do you know how many custom screws we crank
out on the old Brown and Sharpe screw machines? Custom screws. There
must be, what, fifty million stock screws in the world? And these guys
sit around drawing the parts without any consideration of the fastener,
and then they invent a custom screw to put the widget together. It isn't
cleverness, it's ignorance.
